The polishing method of tungsten rod and tungsten plate
1. The polishing method of tungsten rod：The regular round tungsten rod polished to the mirror can use 2000 - dimensional diamond grinding wheel to be polished and grinded in centerless grinder.
2. The polishing method of tungsten plate: regular square is generally used in the surface grinding machine, you can use 2000 grain size diamond wheel to polish.
The machinability of tungsten rod and molybdenum rod is poor. In order to improve the machining efficiency and machining quality, the following methods are used to improve the machinability of tungsten rod.
The surface of tungsten molybdenum rod billet has hard oxide layer, when process it, it will make tool wear or produce "knife" phenomenon. Therefore, before processing, we should remove the surface oxide layer and reduce the tool wear.
The temperature of pure tungsten rod is very high, in order to improve the machinability, it is available to use the blowtorch to heat the workpiece to 200 degrees, and then machine it.
