Product Description

316L Stainless Steel Surgical Robot End Effector Gripper Jaws Drive Pin Shaft Turn-Mill Machining

Precision Medical Component Machining

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.

MATERIAL 316L PROCESS TURN-MILL 5-AXIS TOLERANCE ±0.005 mm FINISH Ra 0.4 µm

Material Excellence: 316L Stainless Steel

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.

Chemical Composition – 316L (wt %)
C Carbon	≤ 0.030
Si Silicon	≤ 1.00
Mn Manganese	≤ 2.00
P Phosphorus / S Sulfur	≤ 0.045 / ≤ 0.030
Cr Chromium	16.0 - 18.0
Ni Nickel	10.0 - 14.0
Mo Molybdenum	2.00 - 3.00
Fe Iron	Balance

Mechanical & Physical Properties
Tensile strength	≥ 485 MPa
Yield strength (0.2% offset)	≥ 170 MPa
Elongation	≥ 40%
Hardness	≤ 95 HRB
Density	7.98 g/cm³
Magnetic response	Non-magnetic (austenitic)

KEY ADVANTAGE: 316L maintains stable, corrosion-resistant, non-magnetic surfaces through repeated autoclave/EtO sterilization cycles, while low-carbon chemistry supports cleanroom-grade passivation – essential properties for surgical-robot end effectors and instruments.

Turn-Mill Compound Machining Capabilities

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.

Feature	Capability
Turning (OD / ID)	Ø2 - 200 mm, Ra 0.4 µm
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
Serration / knurling / slots	Custom profiles for gripper jaws and grips
Inspection	CMM, first-article report, 100% of critical dimensions
Finishing	Deburring, passivation, mirror polishing, ultrasonic / IPA cleaning

PROCESS BENEFIT: Single-setup mill-turn machining ensures tighter true position, shorter lead times, and eliminates re-clamping marks – ideal for multi-feature surgical-robot end effector surfaces.

Component Highlights & Key Advantages

End Effector Body

One-piece mill-turn body reduces joints and assembly tolerance
µ-level mating faces for tool and instrument interfaces
Clean internal channels for fluid/gas/guide passages
Lightweight yet rigid 316L architecture

Frequently Asked Questions

What materials can you machine for surgical-robot components?

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.

What tolerance and surface finish can you achieve on the end effector and drive pin shaft?

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.

Do you accept prototypes and low-volume orders?

Yes. Minimum order quantity is 1 piece for prototypes, and we scale seamlessly from R&D batches to full production runs without process changes.

How do you keep 316L parts clean and biocompatible?

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.

What is the lead time, and how do you ship?

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.
