How are tungsten carbide parts made?

Choice of Processing Methods

For tungsten carbide products with complex shapes, we usually use sintering processing technology for shaping. This method allows for the production of complex shapes while maintaining the material’s mechanical properties and allowing for necessary dimensional adjustments. For tungsten carbide products with high precision requirements, the following machining processes are employed.

Fast Wire EDM Cutting

First, use wire EDM to cut tungsten steel material into the desired shape and size.

Medium Wire Cutting

Subsequent fine cutting is performed to achieve more precise shapes.

Grinding

Grinding includes surface grinding, internal cylindrical grinding, external cylindrical grinding, internal and external cylindrical grinding, centerless grinding, and PG profile grinding, etc.:

• Surface grinding: Mainly used for processing the surfaces of square parts, enabling control of surface parallelism and perpendicularity, as well as step grinding.
• Internal cylindrical grinding, external cylindrical grinding, and internal and external cylindrical grinding: Specifically used for processing circular parts and enable control of concentricity.
• PG profile grinding: Specializes in processing curved surfaces and the machining of carbide tip positions, meeting the requirements of programmed grinding.

Grinding is used to generate the required shapes and dimensions.

CNC Machining

Further machining is performed using CNC machine tools after quenching to achieve subtle deformation. It is highly efficient, but equipment costs are typically high.

CNC Turning

CNC lathes are used for complex surface machining to chamfer the faces of the parts and precisely control chamfer angle tolerances. CNC lathes are used to machine holes and slots in the parts.

EDM Machining

EDM machining is mainly used for blind hole forming, while slow wire cutting is more suitable for through-hole machining, and both can achieve micro-hole machining.

EDM machining is performed to shape areas requiring tight tolerances.

Slow Wire Cutting

Finally, slow wire cutting is used for precision cutting, ensuring that the finished dimensions meet the design requirements.

By employing the above processes in combination, we can achieve the production of tungsten carbide products that meet the design requirements. Our technicians have undergone extensive training to ensure the quality of each process. Our precise machining capabilities are one of our major advantages.
