Precision machinery Tungsten Carbide Grinding & Threading


What makes Tungsten Carbide difficult to machine?

Tungsten Carbide, also known as Cemented Carbide, is an alloy of tungsten and carbon.  It is approximately 2-3 times as rigid and dense as steel, and it is highly resistant to deformation at both extreme low and high temperatures.

This material is incredibly hard and difficult to machine, since most of the machine bits and tools are made of Tungsten Carbide themselves.  Generally, it is impossible to be machined by traditional machining process.  Though it can be machined by special tools, such as PCD, CNB, and ceramic tools, these cutting tools lose their sharpness easily due to the extreme hardness of Tungsten Carbide.

Tungsten Carbide is widely applied in the Precision Machining industry, especially within sectors such as metal machining, metal forming tools, cutting tips, etc.

Due to its material properties of high hardness and rigidity, it is invaluable in making hardmetal, as well as making mill products, high-speed tools, military weapons, and other rugged applications.

Many of our clients specialize in Tungsten Carbide molds and punches machining.  They have encountered numerous difficulties in machining this material, and even tried out with other ultrasonic brands in the past.  However, the processing time was awfully long, and the tool life was not only short but unstable.

That was when they came to HIT's Ultrasonic Machining Module!  We offer a comprehensive solution in machining these difficult-to-cut materials.  With the assistance of our Ultrasonic Machining Technology, our clients stopped worrying about spending excessive amount of money on the tools due to unstable tool life.  The processing time can also be effectively reduced, resulting in a huge reduction in the production costs.  We can assure our clients of matching up with their requirements or even achieving  better outcome!
