What Are the Key Factors for Achieving Longer Tool Life with Aluminum Milling Inserts

Achieving longer tool life with Aluminum Milling Inserts is a crucial factor for any manufacturing process. There are several key factors that must be considered when selecting the right inserts to maximize tool life. These factors include material type, coating type, insert geometry, cutting speed, feed rate, chip load, and coolant type.

The material type of the insert should be chosen based on the material being machined. Different materials require different inserts, so selecting an TCGT Insert insert that is optimized for the material is essential for achieving the best results. The coating type of the insert should also be considered, as different coatings can increase tool life and performance.

The insert geometry is also an important factor in achieving longer tool life and performance. Inserts with better geometry have lower cutting forces and generate less heat. This reduces tool wear and improves the surface finish.

The cutting speed, feed rate, and chip load are also important factors for achieving longer tool life. The cutting speed should be selected based on the material being machined and the insert’s geometry. The feed rate and chip load should also be adjusted accordingly to reduce cutting forces. Too high of a feed rate or chip load will cause increased tool wear.

Finally, the type of VBGT Insert coolant used should also be considered. Different coolants can provide different levels of lubrication, cooling, and chip evacuation. The right coolant can significantly increase tool life and performance.

By considering all of these factors, it is possible to achieve longer tool life and better performance with Aluminum Milling Inserts. By selecting the right insert, material, coating, geometry, cutting speed, feed rate, chip load, and coolant type, it is possible to achieve the best results.

MIG vs TIG Welding: Which One is the Right Choice?

TIG and MIG welding are two common electric arc welding processes in sheet metal fabrication. Both produce welded joints of top-notch quality and efficiently join different materials together. However, they have unique processes, advantages, and disadvantages, making them have different applications.

Choosing between the two sheet metal welding processes should only occur after a thorough MIG vs TIG welding comparison. Therefore, this article will fully do the MIG vs TIG comparison, exposing you to the differences between the processes, their advantages and disadvantages, and their applications so you can decide on the right method.

To choose the better method of the two, you must know their differences. Knowing the differences between MIG and TIG welding will allow you to easily make a TIG vs MIG comparison using the parameters highlighted below.

The power source used by both welding processes is a major parameter when looking at the MIG vs TIG comparison.

TIG welding uses AC or DC power sources depending on the type of metal and the desired type of electric arc. The AC power source used in TIG welding is more suitable for Aluminum due to its cleaning action (i.e., it removes oxide from the metal surface). In contrast, the DC power source is applicable for creating strong electric arcs.

MIG welding uses only a DC power source.

Material compatibility is not a cogent MIG vs TIG welding comparison parameter compared to the power source because there is a slight difference between both processes.

Both welding processes are compatible with the same materials, such as Aluminum, carbon steel, and stainless steel. However, you can consider the thickness of the material to choose between the two methods.

TIG welding is more suitable for working with thick metals due to the better operational control, reducing the tendency to destroy the workpiece.

MIG welding uses consumable electrodes, while TIG uses non-consumable electrodes.

Electrodes functions in creating electric arcs, acting as fillers, or in electric conduction. Due to the difference between both processes in electrode use, this is a major parameter in the MIG vs TIG welding comparison.

Two types of electrodes are used in electric arc welding: Consumable and non-consumable. Both electrodes create electric arcs. However, during welding, consumable electrodes are consumed as fillers.

Examples of consumable electrodes are mild steel and nickel steel, while non-consumable electrodes are copper-coated carbon, graphite, and tungsten.

Shielding gases are responsible for protecting the welding pool and workpiece from atmospheric contaminants during welding. On the one hand, MIG welding uses CO2 (the most common), helium, argon, and oxygen as shielding gases.

On the other hand, TIG welding uses argon as the shielding gas. In some scenarios, you can use a combination of helium/argon (for welding materials with high nickel content), argon/nitrogen (stainless steel), and argon/hydrogen (stainless steel).

A welding torch generates a lot of heat and must be cool with the right coolant. Two popular coolants used in welding are water and gas.

On the one hand, air cooling is light and cheap but less effective when dealing with very high temperatures. On the other hand, water cooling uses water better than air.

Due to TIG welding generating more heat than MIG welding, it uses water cooling welding torches. Nevertheless, you can still use air cooling welding torches for both processes.

The quality of the welded area is another crucial factor that makes the MIG vs TIG comparison distinct. TIG welding is of better quality as it reduces a clean and beautiful surface finish along the weld line. Hence, it is the better product method requiring a high aesthetic appeal.

MIG is faster than TIG welding because TIG welding requires a higher level of detailing, and it involves using filler materials.

TIG welding is more expensive due to the cost of components and higher welding quality and detailing. It also requires more time which increases the power needed and the cost of power.

The major difference between MIG and TIG welding arises from their components. Below are the different components of both processes.

Here are the most important components of TIG welding you should know when comes to TIG welding:

1.1 Power

The power source can be AC or DC. An AC power source is suitable for working with Aluminum due to its inherent cleaning effect. DC power source produces a stronger arc, but it is only suitable for working with a clean surface, so the gas shield works.

1.2 Torch

A TIG torch comes in many designs. Common ones have an on/off switch and control in the handle. Some use a foot pedal to control these commands. They are majorly water-cooled due to the high heat involved in the process.

1.3 Foot pedal

This is responsible for controlling the amount of electricity that enters the torch. When you push the pedal, the amount of electricity entering the torch increases, and the electric arc gets hotter. This speeds up the welding process. However, be careful of the extra heat and speed.

1.4 Electrode and gas shielding

The electrode tip is responsible for the electric arc shape, while the gas (normally argon) emitted by the nozzle protects the arc and the weld pool. The nozzle requires a gas lens for gas flow. They come in different sizes, which determines the gas coverage.

1.5 Filler material

The filler rod should have a size dependent on the workpiece thickness. Also, the material should match the workpiece.

1.6 Backing bars

They are made from copper or Aluminum and clamped at the back of the welded piece. Here, they disperse heat to cool the weld area. You can also use water-cooled backing bars (which involve circulating cold water through the bar).

MIG welding uses a different set of equipment to achieve the same goals. Below are the important components used in the process.

2.1 Power Source

MIG welding requires a DC power source for the process’s high heat. Hence many MIG welding enthusiasts refer to it as a constant voltage power supply.

2.2 Wire

The wire feeding system should be smooth for better welding quality. There are two major MIG welding wires: flux-core and solid MIG wire. The former is a metal containing a flux compound that forms a gas that protects the arc and the weld pool. This type of wire does not require a shielding gas. In contrast, solid MIG wire doesn’t contain any flux and needs a shielding gas.

2.3 Electrode

Electrodes used in MIG welding are consumables, i.e., used in the welding process. They come in different shapes and sizes, with the common sizes used being: .023, .030, .035, and .045. Of the four, the .035 is the most common.

2.4 Torch

This component protects the arc and transfers current to the wire. They can be water-cooled or air-cooled. When choosing a MIG welding torch, consider the weight, ease of use, extraction, neck config, and cable length.

2.5 Gas shielding

MIG welding uses CO2 or argon as shielding gases. They are responsible for protecting the electric arc and weld pool from atmospheric contaminants.

For people new to the process, you can understand the TIG vs MIG welding comparison by getting to know the process properly. Below is an overview of the principle surrounding both processes, their advantages and disadvantage, and their applications.

TIG welding is an electric arc welding process that uses a tungsten electrode to create an electric arc that generates heat for welding the material.

The heat generated melts a filler material fed by the operator into the joining space or weld pool. During the welding, argon, or other combination such as argon/nitrogen and argon/hydrogen shields the electric arc from contaminants.

TIG welding is the better method for welding metals with a thickness of about 10mm and higher welded part quality. However, it is slower since it involves manually feeding the filler material. The electrode is non-consumable, and it creates a deep penetration.

  • With high precision and accuracy
  • Delivers quality welded joints, which improves its level of aesthetics
  • It is environmentally friendly
  • Gives the operator better control
  • There is lower maintenance and operation cost since it uses non-consumable electrodes
  • An expensive process due to the need for filler materials.
  • It is a slow process
  • Requires a clean welding surface

For welding thin metals

TIG welding has better operational control, making it highly precise and accurate. Hence it is the better method for welding metals with thin thicknesses.

For welding aluminum

Aluminum and other metals such as copper and titanium are sheet metals with low thickness. Also, they require an aesthetic finish without a loss in their functionality. TIG welding accuracy and better-welded joints make it the most applicable electric arc welding process for such metals

Suitable for short production runs

Due to its accuracy, TIG welding is the better method for short production runs. However, it becomes more complex and expensive when you use it for long production runs.

For making products that require aesthetics

TIG welding delivers a quality welded joint making it the better welding method with aesthetics. Hence it is applicable in the artwork, construction, etc., where aesthetics is a selling point.

MIG welding is an electric arc welding method that uses a consumable electrode to create an electric arc that generates heat for welding the material. During the welding process, CO2 shields the electric arc from contaminants.

Unlike TIG welding, MIG welding doesn’t need a filler since the electrode is consumable. Also, the process is semi-automatic (or sometimes automatic) due to these consumable electrodes.

-The welding process is fast and cheap-With accurate -It is semi-automatic or automatic-Produces a clean welded line

-May not be reliable due to unstable electric arc -It is not environmentally friendly due to the production of smoke and fumes-Not suitable for thin material as it can burn it

For welding thick metal parts

MIG welding uses a consumable electrode that is a filler and solidifies welding. This makes it easier to weld thick metals.

Applicable in welding low defect parts

MIG welding is not a start and stops mechanism like TIG welding. Its continuous nature reduces the chances of welding defects, making it the perfect method for welding low-defect products.

Welding longer production runs

MIG welding is production efficient and easily managed. Hence it is the better method for long production runs.

According to sheet metal fabrication experts, MIG welding is better than TIG welding. Below are a few reasons why MIG welding is better:

MIG is more diverse

MIG welding has higher diversity due to the use of consumable electrodes. The process makes it easier to join two metal parts together without stress.

MIG has a better speed

MIG welding is an automatic or semi-automatic process. Hence it is faster than TIG welding. Also, MIG welding is continuous without focusing on details like TIG welding.

MIG is easier to operate

TIG welding requires the operator carbide milling inserts to have high technical expertise before considering the process. On the other hand, MIG welding does not require much technical expertise giving it batter ease of operation.

MIG and TIG welding processes are common electric arc welding processes with a wide range of material compatibility. Both methods are unique, with different advantages, disadvantages, and applications. To choose effectively for your project, you can make a comparison to show the most compatible one for your project.

What is the main difference between MIG vs TIG welding?

The major difference between TIG and MIG is based on their application and principle. MIG is more suitable for thick metals, unlike TIG welding, while TIG welding is ideal for thin metals due to the operational control. Also, MIG welding uses a consumable electrode that acts as a filler, while TIG welding uses a separate filler. You can check other differences between MIG and TIG welding above.

Is MIG or TIG better for welding aluminum?

Both processes are suitable for aluminum welding. However, most sheet metal fabricators would choose TIG welding because Aluminum is a light material that requires better operational control. Also, Aluminum is used for its aesthetic appeal, and TIG welding’s quality welding makes it the better option

Should I Choose riveting Over Welding?

Riveting and welding are both joining methods with their advantages and disadvantages. For example, riveting is a temporary method, while welding is permanent. Also, welding has less aesthetic appeal than riveting. Considering such advantages and disadvantages would be best before choosing between both processes.

Want to get some knowledge of threads?Focus on what is important about threads

Contents hide 1Thread formation and construction 2Processing method of thread 3Methods of machining the thread on the workpiece with finishing tools.Thread formation and construction

(1) The formation of screw thread: a point on the cylindrical surface makes constant rotation movement around the axis of the cylinder, and at the same time, it also makes constant linear movement along a straight line. The trajectory of this composite movement is the helix.

(2) Thread structure: the convex part of the thread is called the top of the tooth, and the groove part is called the bottom of the tooth. In order to prevent the thread from damage at the end during installation, the thread shall be processed into tapered chamfer or spherical rounding at the beginning of the thread. At the end of the thread there is a runout or undercut.

Structural element of thread

(1) profile: made of triangle. Trapezoid, zigzag, square, etc.

(2) Nominal diameter: refers to the diameter representing the specification and size of the thread, generally refers to the major diameter of the thread. D (external thread) or D (internal thread).  

(3) Number of lines: threads are divided into single line and multi line. The thread formed along one helix is called single line thread; the thread formed along two or more helixes is called multi line thread. In n.  

(4) Pitch and lead: the axial distance between the two adjacent threads on the pitch diameter line corresponding to the two points, called pitch, expressed as P. The axial distance between two adjacent teeth on the pitch diameter line corresponding to two points on the same helix is called the lead, which is expressed in S. It can also be understood as the distance raised by turning a circle. For single thread, the lead is equal to the pitch, i.e. s=P. Multi thread s=n × P.

(5) Direction of rotation: the direction of rotation of the thread can be divided into left and right. The screw in when rotating clockwise is right-hand thread; the screw in when rotating counterclockwise is left-hand thread. When connecting internal and external threads, the above elements must be the same before they can be screwed together. The three elements of thread: profile, diameter and pitch are the most basic elements to determine the thread. If the three elements meet the national standards, they are called standard threads; if the profile meets the standards, but the diameter or pitch does not meet the standards, they are called special threads; if the profile does not meet the standards, such as square thread, they are called non-standard threads. 3. Type of thread connection thread: common thread with triangular profile.

Transmission thread: trapezoid thread, serrated thread and square thread. 4. The structure classification thread distributed on the outer surface of the parent body is called external thread, and the inner surface of the parent body is called internal thread. The thread formed on the cylindrical body is called cylindrical thread, and the thread formed on the conical body is called conical thread. The connection is mostly single line, and the transmission is double line or multi line; according to the size of the teeth, it can be divided into coarse thread and fine thread. According to the different use occasions and functions, it can be divided into fastening thread, pipe thread, transmission thread, special thread, etc. Among the cylindrical threads, the triangular thread has good self-locking performance. It is divided into two kinds of coarse teeth and fine teeth. Generally, coarse thread is used for connection. The fine teeth have small pitch, small rising angle and better self-locking performance. They are commonly used in thin-walled tubes with small parts, such as vibration or variable load connections and fine adjustment devices.

Pipe thread is used for tight connection of pipe fittings. The rectangular thread has high efficiency, but it is often replaced by trapezoidal thread because it is not easy to grind and it is difficult to screw in and center the internal and external threads. The working edge of the serrated thread is close to the rectangular straight edge, which is mostly used to bear the unidirectional axial force.

The taper thread is triangular in shape, which mainly depends on the deformation of the thread to ensure the tightness of the thread pair. It is mostly used for pipe fittings. According to the tightness, it can be divided into sealing thread and non sealing thread.

Processing method of thread

(1) The method of directly machining thread with mould

(2) The processing method of forming and rolling die to produce plastic deformation of workpiece to obtain thread. The advantages of thread rolling in thread rolling machine are: the surface roughness is less than turning, milling and grinding; the surface of thread after rolling can improve the strength and hardness due to cold work hardening; the material utilization rate is high; the productivity is doubled than that of cutting, and it is easy to realize automation; Rolling die has a long life. However, the hardness of the workpiece material is not more than hrc40, the accuracy of the blank size is required to be high, the accuracy and hardness of the rolling die are also required to be high, so it is difficult to manufacture the die, and it is not suitable for the thread with asymmetric rolling Profile. According to the different rolling die, thread rolling can be divided into two types: thread rolling and thread rolling. The two thread rolling plates with thread profile are staggered by 1 / 2 pitch, and the static plate is fixed, and the moving plate moves in a reciprocating straight line parallel to the static plate. When the workpiece is sent between the two plates, the moving plate moves forward to rub and press the workpiece, making its surface plastic deformation and forming a thread.

There are three kinds of rolling: radial rolling, tangential rolling and rolling head rolling.

Radial thread rolling: two (or three) thread shaped thread rolling wheels are installed on mutually parallel shafts, the workpiece is placed on the support between the two wheels, and the two wheels rotate at the same speed in the same direction, one of which is also used for radial feed movement. The workpiece is driven by the rolling wheel to rotate, and the surface is extruded radially to form a thread. Similar rolling method can also be used for some screws with low precision requirements.

Tangential thread rolling: also known as planetary thread rolling. The rolling tool consists of a rotating central thread rolling wheel and three fixed arc-shaped thread plates. During rolling, the workpiece can be fed continuously, so the productivity is higher than that of thread rubbing and radial rolling.

Thread rolling head: it is carried out on an automatic lathe and is generally used to process the short thread on the workpiece. In the rolling head, there are 3-4 rolling rollers evenly distributed around the workpiece. When rolling, the workpiece rotates, and the rolling head feeds axially to roll the workpiece out of the thread.

Methods of machining the thread on the workpiece with finishing tools.

Thread milling: on the thread milling machine, use the disc milling cutter or comb milling cutter for milling. Disc milling cutter is mainly used for milling trapezoid external thread of screw rod, worm and other workpieces. Comb milling cutter is used for milling internal and external common thread and taper thread. Because the length of its working part is longer than the length of the thread to be processed by multi edge milling cutter, the workpiece can be processed only by rotating 1.25 ~ 1.5 revolutions, with high productivity. The pitch accuracy of thread milling can reach 8-9 grades, and the surface roughness is r5-0.63 μ M. This method is suitable for mass production of general precision thread workpiece or rough machining before grinding.

Today, the machining center with advanced technology has become an irreplaceable tool for all production enterprises. Therefore, more and more thread machining is carried out by milling, with high efficiency, high step simplification and high precision, thus bringing greater benefits to enterprises. In order to meet this demand, many companies are born on demand. For some special needs of the thread to provide professional programs.

Thread grinding: it is mainly used to process the precise thread of the hardened workpiece on the thread grinder. According to the different cross-section shape of the grinding wheel, it can be divided into two kinds: single line grinding wheel and multi line grinding wheel. The pitch accuracy of single line grinding wheel is 5-6 grade, and the surface roughness is r1.25-0.08 μ m, so it is convenient for grinding wheel dressing.

This method is suitable for grinding precision screw, thread gauge, worm, small batch of thread workpiece and precision hob. There are two kinds of grinding methods: longitudinal grinding and cut in grinding. The width of the grinding wheel with longitudinal grinding method is less than the length of the thread to be grinded, and the thread can be grinded to the final size after the grinding wheel moves longitudinally once or several times. The width of the grinding wheel of the cut in grinding method is larger than the length of the thread to be grinded. The grinding wheel cuts into the surface of the workpiece radially, and the workpiece can be grinded after turning about 1.25 revolutions. The productivity is higher, but the precision is slightly lower, and the dressing of the grinding wheel is more complex. The cut in grinding method is suitable for shoveling large quantities of taps Coated Inserts and grinding some fastening threads.

Thread grinding: the nut type or screw type thread grinding tool is made of soft materials such as cast iron. The parts on the workpiece where the processed thread has pitch error are grinded by forward and reverse rotation to improve the pitch accuracy. The hardened internal thread is usually eliminated by grinding to improve the accuracy.

Tapping and threading: tapping is to use a certain torque to screw the tap into the pre drilled bottom hole on the workpiece to process the internal thread. Threading is to cut the external thread on the bar (or tube) workpiece with a die. The machining accuracy of tapping or threading depends on the accuracy of tap or die. Although there are many ways to process internal and TCMT Insert external threads, small-diameter internal threads can only be processed by taps. Tapping and threading can be done by hand or by lathe, drilling machine, tapping machine and threading machine.

Notes on Turning Thread: considering the expansion of thread processing profile, the large diameter of external thread (nominal diameter d) should be turned 0.2-0.4mm (about 0.13p) smaller than the basic size, to ensure that there is a width of 0.125p (P is pitch) at the top of the thread after turning, and to ensure that the diameter of the bottom hole is – P when boring the bottom hole of internal thread..

Thread seal: any plane can’t be in close contact with each other. It needs leak proof seal. The traditional method is to use rubber, asbestos, metal and other gasket, but it will leak soon due to aging or corrosion. The solid gasket is replaced by anaerobic adhesive, which can realize close contact after curing and make the sealing more durable. Metley super lubricant is a kind of special inert material with many uses. It is used for sealing of threaded pipe joint and plug, sealing of flange mating surface, sealing of mechanical box mating surface and so on. It has good leak proof effect.
