Electroplated Diamond tools

Electroplated Diamond tools
  • Product：ELECTROPLATED DIAMOND/CBN BURS
  • Specification：Custom made according to your request.
  • Characteristics：Specialized in grinding work piece of glass. When CBN cutter is working on CNC milling machine, the controller should have pet drilling function. Since as the S = 20000 RPM, F = 100, the cutting depth is not over 0.01mm, otherwise it will cause bad result of chip removal. It is related to the CBN grain size. The CBN grain size is proportional with the surface roughness of work piece. It’s more like grinding glass than cutting glass. The spindle runout of machine will influence the accuracy of cutting. According to experiments, the diamond holes of CBN cutter will be blocked for deeper cutting length, then the cutting oil or cooler cannot take chips out. It will caused damage of cutting edge and short tool life. That’s our interior experiment result.

This type of CBN cutter is specialized for grinding glass parts. The controller should have pecking function to avoid bad chip removal, which is related to CBN particles since the particle size is in proportion to the roughness of surface. We should say “grinding glass” instead of “cutting glass.”The spindle deflection will influence the grinding accuracy. Grinding is based on the consideration of smoothness, flatness, and parallelism. Press the surface of glass slowly and grind it by using abrasive. It is hard to control the smoothness, flatness, and parallelism under speedy cutting.

Grinding can be divided into coarse and fine grinding (fine grinding can be told as polishing). Coarse grinding is with bigger particles, it may increase the efficiency to get rid of thickness. When it reaches predetermined thickness, use find grinding to polish the surface of light transmittance and clarity. This way can restore the clarity of glass surface and light transmission.
