-Applicable scenarios ： Need to control End face runout, coaxiality, and mating surface roughness Ring/disk type/bearing position parts (such as flanges, bearing seats, sealing end caps, hydraulic valve plates).

- Our Advantages

Car grinding integrated/vertical rigidity: Vertical layout suppresses gravity deformation, with end faces and inner and outer circles Coaxial is more stable 。

High demand cooperation: The bearing position and sealing surface can reach after grinding Ra ≤ 0.8 μm (Higher evaluation up to Ra 0.4 μ m level)

- Ability and Indicators (Typical)

Representative workpiece: Ø1600 × 800 mm Grade vertical grinding parts; Grinding of bearing position/end face/sealing surface.

Accuracy: Key position ±0.005 mm ； End face runout and coaxiality/roundness shall be controlled according to the drawings; Grinding/grinding at μ m level 。

- Quality and Delivery

Key features of CMM full inspection; Equipped with environmental/plug/roughness gauges.

Dimensional reports and grinding process records can be attached to ensure traceability.
