Medical Devices
Medical devices cover surgical instruments, orthopedic implants, dental implants, minimally invasive catheters and surgical implant components. Common materials include 316L stainless steel, titanium alloy and cobalt-chromium alloy, with stringent requirements for surface finish, biocompatibility and defect-free quality.
Titanium alloy is prone to work hardening and surface burning during machining, requiring staged progressive grinding: coarse grinding removes tool marks and heat-affected layers, intermediate grinding refines the surface, and fine polishing reaches the target roughness, with grinding pressure and cooling controlled at every step to avoid subsurface damage.Lean Abrasives's CBN and diamond grinding wheels are suitable for cylindrical grinding of precision mating surfaces such as bone screw outer diameters and articulating hinge pins, stabilizing dimensional tolerance and roundness while reducing titanium grinding burn.
Our high-precision sanding belts cover progressive grits from 120# to 1200#, supporting multi-stage processing of surgical instruments from coarse deburring to satin finishing. Flap wheels conform to contoured surfaces of forceps, needle holders and other shaped instruments.
Polishing wheels are used for final mirror finishing of surgical instruments. Non-woven polishing brushes and nylon roller brushes gently remove micro-burrs and oxide discoloration without creating new scratches. Sanding discs, abrasive discs and sanding paper are used for manual touch-up of narrow gaps and hard-to-reach corners.
