CNC Grinding Parts
Manufacturer of Accurate CNC Grinding Parts by JIOU TIAN
As a manufacturer of precision-driven CNC grinding parts, JIOU TIAN provides incredibly accurate components to industries that require perfect surface finishes and accuracy down to the micron level. We manufacture shafts, gears, bearing races, and bespoke profiles for use in semiconductor, automotive, aerospace, and medical applications using state-of-the-art CNC surface grinders, cylindrical grinders, and centerless grinding systems. Our grinding procedures guarantee smooth integration in high-performance components by achieving tolerances as close as ±0.001mm.
Superior Grinding Skills
- As a CNC grinding parts manufacturer, our areas of expertise are:
- Surface grinding: Mold plates, tooling dies, and optical mounting surfaces must be flat within 0.002 mm.
- Cylindrical grinding: ±0.003mm precision in diameter for fuel injector parts, spindle shafts, and hydraulic rods.
- Centerless Grinding: Producing rollers, bushings, and pins in large quantities with Ra 0.1μm finishes.
- ID/OD Grinding: intricate geometries with concentricity less than 0.005mm, such as ceramic insulators and valve seats.
Assurance of Quality and Certifications
- Workflows certified by JIOU TIAN under ISO 9001:2015 include:
- Rockwell testing is used to verify the hardness of pre-ground materials.
- roundness testers and laser micrometers for in-process inspections.
- Final CMM examination to confirm surface roughness, cylindricity, and parallelism in accordance with ISO 1302.
- Complete traceability, including certifications for heat treatment and plating, for defense and medical components.
