While choosing the right implant material is of utmost importance, as discussed in our previous Joint Reconstruction Series post, the significance of optimum surface treatment throughout the entire implant manufacturing process cannot be overstated.
This relates not only to the right surface finish
– be it a high-gloss polish for low friction, a textured surface for easy
osseointegration, or as preparation for subsequent coating, rounded edges, etc.
– but also total compliance with the specified tight dimensional tolerances. The
success of a joint implant is determined by the perfect match between the
various implant components. This depends, to a large extent, on the surface
Advanced composite and metal additive manufacturing components require final surface finishing.
Whenever the surface of aerospace, automotive, creative, dental, industrial tooling, medical and moulding tools are produced with additive manufacturing the surface requires to be improved.
Additive manufacturing, the creation of 3-D solid objects by using a series of layered materials, allows the production of complex individual components from various materials such as plastic, nickel alloys, titanium, stainless steel and precious metals.
It permits the creation of shapes and geometries which are not possible with any other production method. However, the surface finish of parts created with additive manufacturing frequently requires final finishing.
The adaptation to particular work piece shapes and surface requirements can be achieved by the development of tailor-made finishing solutions.
Equipment and process methods for either the intensive or very gentle surface smoothing of such components are available according to their component substrate and design geometry.
Surf-Finisher – a new standard for automated precision surface finishing
Surf Finishing is a new surface finishing technology that can be incorporated in an automated system combining; loading, handling, processing and even inspection all in one which can give an added benefit of retaining traceability on parts.
Surf finishing is a fully automatic, dry and/or wet processing method with; extremely short cycle times, high process stability, repeatability and can provide finishing of precisely targeted surface areas for deburring, surface grinding, smoothing and polishing of delicate, high-value components with complex geometries.
Mass finishing machines come in different shapes, sizes and styles; from vibratory bowls and troughs, high energy centrifugal disk machines to drag finishing. Machines can often be chosen in batch and continuous flow versions and as such their application range is as wide as it is varied. below are just some of the possible applications:
