Performance Highlights
High flatness accuracy
Surface grinding achieves flatness of 0.005mm/300mm, correcting warpage and distortion from prior operations . Standard grinding precision reaches IT6–IT7 grade .
Fine surface finish
Grinding produces finishes down to Ra 0.4μm, improving sealing surfaces, bearing interfaces, and assembly fit .
Multiple grinding methods
We apply peripheral grinding (using the wheel OD) for precision flat surfaces, end-face grinding for high stock removal efficiency, and traverse grinding for large workpieces.
Corrects distortion and cleans surfaces
Surface grinding removes oxide layers, scale, and heat-affected material - preparing blanks for subsequent machining or final assembly.
Broad material compatibility
Carbon steels, alloy steels, stainless steel, aluminum, brass, and cast iron are ground with optimized wheel selection (aluminum oxide, CBN, or diamond) for each material .
IATF 16949-certified facility
Full PPAP Level 3 documentation available - process FMEA, control plans, capability studies.
Quality Control
Applications
Automotive Components
Engine blocks, cylinder heads, brake rotors, and mounting surfaces are ground to flatness and surface finish specifications for gasket sealing and bearing alignment.
Mold and Die Components
Mold bases, die plates, and forming tools are surface-ground to maintain flatness and parallelism - critical for part quality in stamping and injection molding operations.
Hydraulic and Pneumatic Components
Valve faces, manifold mounting surfaces, and pump housings are ground to specified finish and flatness for leak-free sealing.
General Precision Parts
Flat plates, fixture bases, and custom components are surface-ground to correct warpage and prepare surfaces for final assembly.

Why Surface Grinding
For flat surfaces requiring precision, other processes have limitations:
Milling – leaves tool marks; cannot achieve the surface finish or flatness of grinding
Lapping – achieves fine finish but slower and removes minimal material - does not correct major distortion
Hand finishing – inconsistent, labor-intensive, unsuitable for production
Surface grinding delivers the production finishing capability - better flatness and surface finish than milling, with consistent results across batches. For flat components requiring sealing surfaces, bearing interfaces, or assembly-ready finishes - surface grinding is the finishing method.
