01
Hard-to-cut materials
Titanium alloys, Inconel 718, SUS 630, hardened tool steels — backed by an in-house knowledge base of tool life and cutting-condition optimisation.
TECHNOLOGY
The Technology of CHUSHAN
“Tighter tolerance.” “Tougher material.” “Faster turnaround.” These are the orders CHUSHAN takes.
02
Thin-wall deformation control
Walls below 0.3mm — bespoke fixturing and staged cutting paths control thermal distortion and elastic springback.
03
Deep-hole boring
Length-to-diameter ratios up to 30:1, bore tolerance H6 — gun-drills and ID grinders chain from rough to finish in one pass.
04
Mill-turn geometry
Y-axis milling, B-axis tilt, sub-spindle transfer — a single set-up replaces three or more secondary operations.
05
Mirror-finish grinding
Surface roughness below Ra 0.025µm — mirror-grade work on spindle shafts and arbors. Flatness held to 1µm per 100mm.
06
Full-CMM verification
Zeiss CONTURA G2 CMM — each shipment ships with a PDF inspection report, with full-batch SPC summaries on request.
Case studies coming soon.
