Product Details
High Speed & High Pressure Lapping Machine
The EJW-380HSP series is a polishing machine equipped high-speed and high-pressure process function.
This machine is designed for high-precision and high-efficiency polishing of substrate-shaped polycrystalline sintered diamond (PCD) and CVD diamond. The temperature control system, especially developed for PCD polishing, responds to the temperature rise of the grinding wheel and controls the spindle speed and pressure to maintain the optimum processing temperature.
In addition, many of the next-generation materials are hard, brittle, and difficult-to-cut materials, and the specifications are such that they can withstand severe processing conditions using high pressure and high rotation speeds that achieve high-efficiency polishing.

Cylindrical Polishing Machine
This machine is a special polishing machine designed to mirror-finish for cylindrical surface. A combination of a 3D polishing pad for aggressive polishing along the cylindrical shape and CS slurry that acts as a carrier for diamond abrasive grains can provide a surface roughness comparable to ultra-precision mold.
