Automotive brake disc has high requirements for finish and processing efficiency, usually the surface roughness is required to be Ra1.6
A cutting tool in metal working can be defined as “any tool that is used to remove metal from the work piece by means of shear deformation”.
The part of the cutting edge that is not involved in the cutting is damaged by a chip hammer.
The face and the flank are pain surfaces, the cutting edge can be assumed to be a line.
Mono-crystalline diamond die blanks can be used in hot drawing and cold drawing of various metal wires, with high quality polished surface and long service life.
A milling cutter is a rotary tool with one or more teeth used for milling. When working, each cutter tooth intermittently cuts off the margin of the workpiece.
Replacement of passivated sand. When the passivation time of 400# sand tool is more than 20 minutes, the sand needs to be replaced or redeployed.
The dicing blade used in wafer cutting is a missing link in China's semiconductor packaging industry chain, which has been dependent on import for a very long time.
Customers use ceramic diamond cylindrical grinding wheels to grind PCD roller tools. At first, the customer was not satisfied with the chipping effect of using a domestic brand grinding wheel. Currently, customers use a resin diamond grinding wheel from a certain European brand to achieve better grinding results, but the cost is relatively high.
A diamond roller is a high-efficiency, long-life, low-cost grinding wheel dressing tool that uses electroplating or powder metallurgy methods to inlay a large number of diamond particles on the surface of a steel roller. It is used for special machine tools and gear grinders for mass form grinding. Rotating at a certain speed (thereby reducing the relative speed between the roller and the grinding wheel) produces grinding and rolling effects on the surface of the high-speed rotating grinding wheel, so that the grinding wheel obtains a sharp working surface that matches the roller profile.
