Tungsten Carbide Ball V-shaped Groove Grinding Process

The specific requirements of each procedure of tungsten carbide polished ball as follow: Coarse grinding at the beginning, machined by vertical steel ball machine and uses 100# diamond resin grinding wheel (grain size is 100). Before the grinding, the grinding wheel to be ball milled with the corresponding specifications of the groove. In addition, the groove depth is generally equal to 1/5-1/3 of tungsten carbide polished ball and runout groove should ensure that within 0.03mm.

Then the fine grinding, which also machined on vertical steel ball grinding machine and uses 150# diamond grinding wheel (the grain size is 150, finer suitable for fine grinding). It is similar to coarse grinding, the grinding wheel to be ball milled with the corresponding specifications of the groove. The groove depth is generally equal to 1/5-1/3 of tungsten carbide polished ball and runout groove should ensure that within 0.03mm.

The next is coarse pestle, which uses grinding plate for machining on vertical steel ball machine. The lower grinding plate opening 90 ° symmetrical V-groove, milled plate installation alignment groove runout less than 0.02mm. Before the grinding, the groove should be pre-grinding by the standard ball, which adopts concentration 30% grinding fluid and 140/170# SiC （grain size is 140/170） as grinding compound. Disposable add a little abrasive, with a smaller flow, pressure control in 4KN-6KN, speed 25-30r / min, grinding to a balance of + 0.03mm-0.04mm, 0.001mm in control of roundness, approved changes in diameter assurance within 0.002mm, the surface roughness of less than Ra0.4.
