The importance of surface finishing techniques in the development of medical devices and orthopaedic implants cannot be overstated. These techniques play a critical role in ensuring that medical equipment is of high quality and meets the necessary standards for professional performance. Orthopaedic implants, in particular, require dimensional accuracy, which can only be achieved through effective lapping and polishing processes.
Medical devices often have complex parts that need to be finished to exacting specifications, including sharpness, roughness, alignment, and more. To achieve this, accurate measurements are necessary, which are possible using surface finishing techniques.
Kemet Process Development Laboratories has been a leader in this field, offering a wide range of special-purpose polishing machines for medical implants. The company's latest innovation, the KemiSphere II, is a bench-top spherical/ball lapper/polisher that can lap and polish spherical forms to roundness better than five microns, with a mirror finish. The two-stage process is simple, repeatable, and affordable, and can process a variety of materials and joint sizes.
In the manufacture of tibial trays and hips, the majority of production costs come from process consumables. As a manufacturer of these consumables, Kemet is well-positioned to help reduce costs. More importantly, the company's expertise in surface finishing enables them to develop new processes and consumables to increase productivity and reduce the cost per part. The Kemet Tibial Polishing Cell, for example, has been specifically designed for finishing large quantities of replacement knee parts, such as tibial trays.
Kemet offers a range of additional products, including ultrasonic cleaning tanks, aqueous cleaning fluids that comply with ISO standards, passivation lines that comply with ISO 7 cleanroom standards, and vacuum solvent cleaners that minimise solvent loss, significantly reducing process costs. The company is a global leader in precision surface finishing and is fully equipped to offer complete support and service for all its polishing systems.
