Double Sided Grinder

GC-2M84100B Double-Sided Grinder

Double Sided Grinding Machine can meet the requirements of high-precision surface grinding or fine grinding.

Item name: GC-2M84100B Double-Sided Grinder

Grinding Disc Size: φ1000xφ450×55, φ1000xφ350×55

Application: Used for processing hydraulic components, compressor parts, engine parts


Crownkyn Superhard GC-2M84100B double-sided grinder can meet the requirements of high precision surface grinding or fine grinding, by removing the excess material on the two surfaces of the parts, can obtain extremely accurate geometric precision and surface finish. Usually, this is the last grinding step in the mechanical production chain to improve or correct the geometry of parts from sintering, sawing, molding or similar operations with an accuracy of 0.001m. Depending on the application, grinding from only one surface is also possible.

Widely used in double-sided precision grinding of automotive steering valve parts, refrigeration compressor parts, oil pump nozzle parts, engine parts, high-precision bearings, seals and other products.

When the machine is working, the upper and lower grinding discs and the planet wheel rotate simultaneously to drive the workpiece to reciprocate between the two grinding discs. When grinding, you can use diamond grinding disc, CBN (cubic boron nitride) grinding disc, cast iron disc to process workpieces to meet the different requirements of various products, so as to achieve double-sided precision grinding on workpieces made of various materials.
