Precision surface grinding utilizes high-speed abrasive wheels composed of aluminum oxide, silicon carbide, or CBN to achieve sub-micron flatness, parallelism, and mirror-grade surface finishes.
Engineering Specifications & Parameters
Applications
Precision linear ways, mold parting surfaces, gauge blocks
Coolant Type
Synthetic micro-emulsion with high thermal absorption
Abrasive Wheels
Aluminum Oxide, Silicon Carbide, CBN, Diamond
Flatness Accuracy
0.001 mm / 300 mm

Grinding Physics & Sub-Micron Accuracy
Surface grinding removes microscopic material chips through abrasive micro-shearing. It is the final finishing operation for hardened tool steels, precision guide rails, and gauge blocks.
Key Performance Capabilities
Flatness & Parallelism: Within 0.001 mm (1 micron) across a 300 mm span.
Surface Finish: Readily achieves Ra 0.1 to 0.2 microns (4 to 8 microinches).
Magnetic Workholding: High-power electromagnetic or permanent chucks clamp ferromagnetic parts with uniform zero-distortion holding.
