Machining tungstenalloys

As mentioned above, tungsten is ultra-hard and is extremely difficult to machine. Some say heating it with a burner improves machinability, and others say machining it under below-zero temperature condition prevents damage to the cutting edges of a tool caused by heat. Nevertheless, we machine tungsten at room temperature.

In order to machine tungsten, you need right cutting tools. We have tried different tool materials such as diamond, CBN, and ceramics. However none of them were as good as tungsten carbide in terms of durability and cost effectiveness. Among tungsten carbide, we choose the one with high hardness and toughness. In addition, tools need sharp cutting edges to reduce cutting forces and prevent the workpiece from cracking or breaking. Since the cutting edges lose their sharpness rapidly when machining tungsten, it is also essential to employ tool geometry which provides efficient chip control. Moreover, we grind our tools in-house to maintain edge sharpness of the tools. Since rapid cutting edge wear is inevitable, we machine tungsten quickly while the tool maintains its sharpness, and regrind the tool as soon as it loses its sharpness. A dull tool causes cracking and chipping around the edges of the workpiece.

It is important to choose the right end mill for your project to achieve the desired outcome. Understanding the different types of end mills and their intended uses can help you make the right choice. It is also important to consider factors such as the material being milled, the depth of cut, and the feed rate when selecting an end mill.

MachinableTungstenAlloy

Sizes of crystal grain of tungsten vary depending on temperature and duration of manufacturing processes. And crystal grain size affects the machinability of tungsten: larger the grain, worse the machinability. Since tungsten crystal grains grow larger by the progress of recrystallization, resulting in significantly worsened machinability, obtaining the material with heat history becomes even more important than when machining molybdenum.

If you are new to machining, you might be wondering what an end mill is. An end mill is a type of cutting tool that is used in milling applications. It is a rotating tool that is used to remove material from a workpiece. End mills are usually made of high-speed steel (HSS) or carbide and come in a variety of shapes and sizes. They are available in solid and indexable milling styles

Consider factors such as material, cutting diameter, flute count, coatings, and cutting speed and feed rate when selecting an end mill. By taking the time to choose the right end mill for the job, you can ensure efficient cutting and a high-quality finish.

Tungstenpowder

Tungsten is produced by sintering tungsten powder at even higher temperature than that of molybdenum. And then, like molybdenum, it goes through processes such as forging, rolling, and swaging. Since crystal grains of tungsten are much harder than that of molybdenum, milling it can rapidly wear the cutting edges of the tool. Even worse, tungsten is brittle and prone to cracking and breaking during machining operations.

Using end mills can be a challenging task for beginners, but with the right tips and techniques, it can be a rewarding experience. Here are some tips and techniques to help beginners use end mills effectively:

Using end mills can be a rewarding experience for beginners with the right tips and techniques. Secure the workpiece, choose the right speed and feed rate, use the right cutting depth, clear chips often, lubricate the end mill, and test the cut before milling the entire workpiece. By following these tips and techniques, beginners can use end mills effectively and achieve high-quality results.

Understanding the Different Types of End Mills is an essential part of learning how to mill. End mills come in a variety of shapes and sizes, each designed to perform a specific type of milling operation. Here are some of the most common types of end mills and their uses:

The end mill is named after its cutting end or tip, which is shaped like a cylinder or ball at the end of a long shank. They feature several end types for cutting, flutes, and point angles.

End mills are commonly used in milling machines, which are machines that use rotary cutters to remove material from a workpiece. The milling machine moves the workpiece against the rotating end mill, which cuts into the material and removes chips of material to create a desired shape.
