Equipment : LB-3000 EX2

Shaft
Axel shaft for a motorcycle made with Ti-6Al-4V. Screw, shaft and head is machined in one process with combined machining.
Equipment : Hicell B-65

Axel Nut
Nut for an axel shaft with cutouts. Ti-6Al-4V.
Equipment : Hicell B-65

Parts for Aviation
Fasteners including bolts, nuts, and bushings for aviation are made with care as surface finish and tolerance requirements are stringent.
Equipment : L-16, B012, LCS, mini-TURN

Machining Center

Roku Roku Sangyo CEGA

CNC machining center with high speed spindle and high precision made by Roku Roku Sangyo. Spindle rotates at 30,000rpm. The positioning precision is ±0.1μm. Used to machine fine parts and features using small diameter end mills such as Φ0.3mm.

FANUC ROBODRILL

FANUC ROBODRILL machines generic parts. The machine is compact and easy to operate. Used primarily for second process after turning. Automatic tool change is quite rapid, useful for mass production.
