Grinding

Grinding is one of our strongest capabilities.
We achieve ultra-high precision on both soft- and hard-sealing surfaces across sizes ½" to 48".
 
Key performance:
· Roundness: 0.01 – 0.02 mm
· Roughness: Ra 0.2 μm
· Stable accuracy for large and heavy components
Our grinding covers carbon steel, stainless steel, duplex steels, hard alloys, and coated surfaces such as HVOF/HVAF and Stellite overlays.
Whether for tight-tolerance soft seals or extremely hard sealing layers, our grinding guarantees perfect spherical matching and superior sealing performance.
