01 — CAPABILITIES

What We Do and How

Machining and cold forming happen in our own plant. Forging, casting, stamping, heat treatment and finishing run through long-term partner plants. One supplier, one point of contact, one quality system.

IN HOUSE

Machining & Cold Forming

6

Done in our own plant, on our own machines.

Cold Forging

Multi-station cold headers form blanks close to net shape, with unbroken grain flow.

5 cold headersSizes 11B – 31B

CNC Turning

Shafts, sleeves, bushings, fittings and flanges turned from bar or blank, including Mazak and Hardinge precision lathes.

17 CNC lathesBar and chuck work

Swiss-Type Turning

Sliding-headstock lathes for small, long and slender parts such as pins, shafts and fittings.

2 Tsugami lathesTurning, drilling and milling in one setup

CNC Milling

Vertical machining centers and a horizontal machining center for blocks, manifolds, flats, slots and hole patterns.

9 machining centersHurco VMX · HTX500

Cylindrical Grinding

Universal and precision cylindrical grinders for bearing seats, shafts and pins.

3 grindersOD grinding

Threading & Secondary Ops

Thread rolling, automatic tapping, slotting, press fitting and ultrasonic cleaning before inspection.

05 — FAQ

Common Questions

What do I need to send for a quote?

A drawing in PDF, DWG or STEP, the quantity, material and finish. If you have no drawing, send a sample or photos with key dimensions and we can draw it for you.

Which materials do you machine?

Stainless steel, carbon steel, aluminum, copper and brass.

Which processes do you do in house?

Cold forging, CNC turning, Swiss-type turning, CNC milling, cylindrical grinding, thread rolling and tapping. Hot and warm forging, casting, stamping, heat treatment and surface finishing are done by long-term partner plants and checked by our QC.

How do you check quality on custom parts?

We measure samples and production lots in our own lab: two CMMs (LK and Zeiss), roughness and contour testers, profile projectors, an optical diameter gauge, a vision system, a metallographic microscope, a hardness tester and thread gauges. Our plant is certified to IATF 16949.

Can you pack under our brand?

Yes. Parts can be packed in bulk cartons or under your label and barcode.
