Crankshafts (forged)
Medium lot: Annual production of 500-2000 pieces

We are capable of working with a wide variety of crankshafts, eccentric shafts, eccentric axes, eccentric holes, etc.
We can meet customer-required tolerances for eccentricity by manufacturing our own jigs.
Normally, it is 0.05.
We have a track record of 0.002 in precision machining.

(Processing process)

Material → NC lathe → M/C → Carburizing and hardening → External diameter grinding → External diameter grinding eccentric part (jig processing) → Lapping → Inspection (3D measurement)

(Crankshafts and eccentric shafts)
We specialize in machining eccentric shafts.

We manufacture shafts for a wide range of fields, including vacuum pumps, compressors, vehicles, machine tools, specialized equipment, specialized machines, agricultural machinery, construction machinery, etc.
We can handle high-precision eccentric machining using NC lathes, M/C, and external diameter grinding.

‣ Eccentricity: up to 0.002
‣ Outer diameter tolerance: up to 0.002
‣ Diagonal oil holes available
‣ Journal polishing available
‣ Heat treatment available: high-frequency hardening, carburizing, vacuum hardening, nitriding, tufftride, etc.


(Automotive parts prototype processing)

We are particularly accepting orders for prototype processing of compressors, pumps, fuel cell parts, inverters, etc.
We can handle all materials, including cutting, sand molds, and die casting.
We process a wide range of items that require both NC lathe and M/C processing.

We measure and guarantee all specified points on the drawing dimensions using precision measuring devices such as 3D measuring instruments, shape measuring instruments, 3D image measuring instruments, and roundness meters.
We also manufacture jigs and other tools in-house, which contributes to short delivery times and low prices.

Our top-tier professionals can accomplish precise machining in any procedure.
