End effectors, gripper jaws and drive pin shafts – precision turn-mill (mill-turn) compound machining built around medical-grade 316L stainless steel with one-setup accuracy of ±0.005 mm, clean biocompatible finish and full material traceability.
For surgical-robot hardware, material selection determines component longevity through repeated sterilization cycles, chemical exposure, and tissue contact. We machine 316L (AISI 316L / 1.4404) as the standard medical grade – low-carbon, molybdenum-bearing austenitic stainless steel with exceptional pitting and chloride resistance, non-magnetic properties, and excellent biocompatibility.

Our multi-tasking mill-turn centers combine turning and 5-axis milling in a single setup. Bars or blanks are fed, turned, milled, drilled, tapped and threaded without re-clamping, eliminating stack-up error and maintaining tight concentricity on slender geometries like drive pin shafts.

| 5-axis milling | Simultaneous 5-axis, complex 3D contours & undercuts |
| Drilling / cross-holes | Ø0.5 - 20 mm, intersecting and angled holes |
| Tapping / thread milling | M1.6 - M12, metric & unified threads |
| Bar-feed / live tooling | Small pins from Ø3 - Ø32 mm bar stock |

We routinely machine 316L and 316 stainless steel, 17-4PH, titanium Ti-6Al-4V, aluminum alloys and engineering plastics such as PEEK. Material certificates are supplied, and we can quote to specified grades per your drawing requirements.
Critical features are held to ±0.005 mm with 0.01 mm concentricity, and mating/sealing surfaces reach Ra 0.4 µm. General features are maintained at ±0.02 mm with Ra 1.6 µm finish.
Yes. Minimum order quantity is 1 piece for prototypes, and we scale seamlessly from R&D batches to full production runs without process changes.
We use dedicated tooling to prevent material cross-contamination, followed by passivation, mirror-polishing and ultrasonic/IPA cleaning. Full material traceability and EN 10204 3.1 certificate options are available for medical programs.
Samples are typically ready in 5-7 working days; bulk production in 12-18 working days. We ship worldwide via express or air/sea freight, with EXW, FOB or CIF terms available.
