Manufacturing Capability
Five process domains with 100% in-house capability. Grinding, turning, gear forming, heat treatment and metrology are all closed-loop within our own system, with no external subcontracting on critical operations.
Scale · Process domain · Leading global brands · Accuracy · In-house ratio
280+ machine tools covering grinding, turning, gear cutting, dedicated lines with heat treatment, and metrology. Every process domain is 100% in-house.

Grinding
Double-disc, profile, centreless and cylindrical grinding for micron-level tolerances.
Turning
Turn-mill centres and 5-axis machining centres form complex rotational parts in one setup.
Gear forming
Hobbing, shaping and two-way rolling keep gears and special slots fully in-house.
Dedicated lines + heat treatment
Screw lines with controlled-atmosphere furnaces for consistent, traceable metallurgy.
Metrology
Full-size 3D inspection, gear composite error and cleanliness testing.
