Product families
Five families, each machined from your drawing. Open one to see materials, process routes and what to send.
01
Made-to-drawing pneumatic valve blocks for railway braking circuits. Interconnected internal passages distribute air and provide mounting interfaces for valves, pressure sensors and pipe fittings.
02
Precision carriers, drive shafts, connecting flanges and internal or external gear rings for robot joint reducers, manufactured to the required fit, runout and surface finish.
03
Precision matched spools and sleeves for VVT oil-control valves and CDC active-suspension solenoid valves, made from alloy steel, stainless steel or alumina ceramics.
04
CNC-turned and milled connector components for signal and current transmission, including RF housings, conductive pins, threaded sleeves, locating bases and locking parts.
05
Precision spools, sleeves, poppet valves, ball plungers and guide shafts for hydraulic valves, pumps and cylinders, machined to the required sliding and sealing interfaces.
Machining processes
From 1 mm Swiss-turned pins to 200 mm turned bodies and 1,100 mm milled blocks, the route is planned from your drawing.
Diameter 1–26 mm
Tsugami, Citizen and Star Swiss-type lathes machine slender shafts, spools, pins and sleeves. Turning can be combined with cross-drilling and cross-milling; key dimensions can reach 0.005 mm, depending on the drawing.
Diameter 1–30 mm
Woen gang-tool lathes machine compact shaft and disc components. Automated loading supports repeat production.
Up to Ø200 mm
Tsugami, Miyano and Doosan turret lathes machine larger shafts and disc-shaped parts up to 200 mm in diameter.
Mori Seiki NT4200 · Nakamura Super NTX · WT150II
Mori Seiki NT4200 and Nakamura Super NTX / WT150II combine turning, milling, drilling and boring in fewer setups. Six-axis robots with 10 kg payloads support automatic loading and continuous production.
500–1,100 mm travel
Brother drilling-tapping centers and Doosan, Mazak and Tongtai machining centers mill, drill, ream and tap plates, housings, valve bodies and fixtures. Travel ranges from 500 to 1,100 mm; typical precision is 0.005–0.01 mm.
Grinding · honing · abrasive flow finishing
In-house centerless grinding finishes shaft diameters; vertical and horizontal honing finishes bores. Abrasive flow finishing removes burrs from internal passages. Thread whirling and rolling support screws, worms and special threads; simple welding and preassembly are also available.
Materials and precision
Precision figures belong to the family shown. Select a family to see its materials and scope.
Production facility
Two main workshops and six production lines run more than 100 machines, including robot loading cells.
Monthly capacity exceeds 100,000 parts. Actual capacity depends on part complexity.
About the company
Inspection and quality
Inspection is part of the process, in a dedicated room with workstations for dimensional checks.
Before machining, we read dimensions, tolerances, surface requirements and inspection notes, and raise questions early.
Parts are measured at inspection workstations against the drawing, in a room set aside for the work.
Reports are provided where agreed. Tell us which dimensions and format you need when you request a quote.
Drawing to production
OEM work and component-level drawing and process development are supported.
STEP 1
Send your drawing with material and quantity. We check geometry, tolerances and finish.
STEP 2
We confirm the machining route, finishing and inspection plan with you.
STEP 3
A sample or small batch is machined and checked, typically in 20–30 days.
STEP 4
Production runs follow the approved process, with reports where agreed.
Typical sample and production lead time is 20–30 days, confirmed per order.
Before you request a quote
Samples, quantities, lead times, materials and reports, answered up front.
Send your drawing with the material, quantity and any finishing, plating or inspection requirements. A link to the drawing is enough to start. We review the drawing before confirming a process route and price.
Order quantities generally start at 10–50 pieces depending on the component. The four listed railway, robot reducer, automotive and electronic product families normally start at 50 pieces. Please discuss hydraulic components, prototypes and smaller batches with us.
Typical sample and production lead time is 20–30 days. The exact time depends on the part, material and quantity, and is confirmed per order.
Typical precision is 0.005–0.01 mm. Tighter figures apply to specific product families and drawings, for example ±0.005 mm for electronic connectors and flanges, and ±0.002 mm with Ra 0.1–0.4 μm for hydraulic components. Each is confirmed against your drawing.
Material certificates, in-process inspection records and finished-part inspection reports are available. Tell us which documents, dimensions and report formats you need when requesting a quote.
