CNC Tooling for Medical Device Manufacturing Malaysia — Process & Procurement Guide 2026

Medical device manufacturing tolerates no ambiguity — not in part geometry, not in surface finish, not in your supply chain documentation. A tooling supplier for this sector must understand the difference between Grade 2 and Grade 5 titanium, know why coolant pressure matters for cobalt chrome, and be able to provide the documentation your ISO 13485 procurement process requires.

KS Precision Tools is ISO 9001 certified and an authorised distributor for MOLDINO, Mitsubishi Materials, OSG, and MRT. Here is what you need to know before sourcing medical tooling.

Titanium machining — grade matters

Titanium is not one material. The two most common grades in medical manufacturing require different tooling strategies:

• Ti-6Al-4V (Grade 5) — used for load-bearing orthopaedic implants (hip stems, knee tibial plates, pedicle screws). High strength, poor thermal conductivity. Requires: sharp cutting edge (honed, not T-land), AlCrN or uncoated submicron carbide, high-pressure coolant (70 bar minimum through spindle), Vc: 40–60 m/min, fz: 0.02–0.05mm. Built-up edge is the primary failure mode — increase Vc before reducing feed.

• Grade 2 CP Titanium — used for non-load-bearing implant shells, dental abutments, and surgical instrument handles. More machinable than Grade 5. Vc: 60–90 m/min with uncoated or TiN-coated carbide. Lower cutting forces — tool deflection on thin-wall features is the primary concern.

Cobalt chrome machining (Co-Cr-Mo)

Cobalt chrome is among the most difficult materials in medical machining — high work hardening rate, abrasive, and generates extreme heat at the cutting edge. Key requirements:

• Use positive rake, sharp-edge geometry with AlCrN or AlTiSiN coating.

• High-pressure through-spindle coolant (minimum 70 bar) is non-negotiable — without it, tool life collapses within minutes.

• Vc: 25–45 m/min for end milling. Lower than titanium — cobalt chrome is harder to cut.

• MOLDINO precision end mills or Mitsubishi Materials solid carbide grades are proven in Co-Cr-Mo — ask our team for the specific grade recommendation for your component.

316L stainless steel surgical instruments

• Use sharp, positive rake end mills and drills — 316L work-hardens rapidly if the tool rubs rather than cuts.

• OSG EX-SUS series drills are specifically optimised for surgical-grade stainless — excellent chip control and point geometry for clean entry and exit.

• For tapping: use spiral flute taps with appropriate pitch for through-holes, spiral point for blind holes. Never use cutting fluid with chlorine content — causes stress corrosion cracking in 316L.

Compliance documentation — what we provide and what we do not

KS Precision Tools is ISO 9001 certified. We are not ISO 13485 certified — and we will not claim to be. What we can provide to support your ISO 13485 procurement process:

1. ISO 9001 certificate (current, scope confirmed)

2. Manufacturer authorisation letters — MOLDINO, Mitsubishi Materials, OSG, MRT

3. Certificate of conformance on request per order

4. Delivery documentation with brand, grade, batch reference, and quantity

5. Company profile and reference customer list for your supplier qualification

We do not repackage or rehandle tooling between manufacturer and your facility. All medical tooling is supplied in manufacturer original sealed packaging — supporting your contamination control requirements.
