Our grinding and finishing operations are critical to delivering components that meet the highest standards of performance, cleanliness, and consistency for medical applications.
Grinding & Finishing for Medical-Grade Performance
- Grinding Capabilities
- We offer precision grinding methods tailored to specific part geometries and functional requirements:
- Square end grinding for coil pipes and compression springs to ensure parallel load-bearing surfaces and reliable seating
- Multi-faceted grinding for tissue anchors and helix components, where precise engagement and repeatability are key
- Consistent control of grind profiles and surface finishes across high-volume production
- We offer precision grinding methods tailored to specific part geometries and functional requirements:
- Centerless Grinding
- Centerless grinding is a high-precision process used to achieve exceptional diameter control, surface finish, and geometric consistency—especially critical in the production of medical wire and tubing components. At Motion Dynamics, we apply this capability to condition raw material, refine component geometry, and support tight-tolerance assemblies where repeatability and surface integrity matter.
- Finishing Capabilities
- Our in-house finishing systems combine mechanical and chemical methods to optimize surface integrity, remove contaminants, and support downstream assembly:
- Vibratory finishing for uniform edge blending and surface smoothing
- Chemical etching for selective removal of Nitinol oxide layers without compromising geometry
- Pickling to clean and passivate stainless and specialty alloys
- Citric and nitric passivation, fully compliant with ASTM A967, to enhance corrosion resistance and ensure biocompatibility
- Electropolishing to improve cleanliness, corrosion performance, and cosmetic finish
- Cold water deburring for delicate parts requiring non-abrasive surface refinement
- Our in-house finishing systems combine mechanical and chemical methods to optimize surface integrity, remove contaminants, and support downstream assembly:
