Knee implant surface smoothness measurement - Fintek can reach surface smoothness values to Ra 0.01μm
On stand 8 at Medical Technology UK, Fintek will show how automated mass and super finishing technologies are advancing the precision of implant and medical device surfaces.
The medical industry demands continual surface improvements to ensure the safety and effectiveness of surgical instruments, tibias, femoral shafts, prosthetic sockets, bone screws, bone plates and more. Precision surface finishing is a vital post-process in their manufacture. It enhances their performance, safety and lifespan in use.
Fintek is the exclusive UK agent for the sales of OTEC Präzisionsfinish GmbH drag finishing and electro-chemical finishing machines. Two technologies that excel at automating in-house medical device finishing. Compact and low capital outlay means their return on investment is quickly realised. The company also provides a full subcontract service and an experienced technical team using the latest equipment from OTEC.
With over 40 years’ experience in medical engineering, aerospace, F1 and other precision industries, Fintek brings a depth of knowledge to surface finishing. Medical devices and implants made from stainless steel, cobalt chrome, titanium and ceramics can reach surface smoothness values to Ra 0.01μm. Using advanced drag finishing and electro-chemical technology, this is achieved quickly, with repeatable precision and quality. Inconsistencies often associated with hand finishing are eliminated.
Improving surface finishing significantly improves the biocompatibility of medical devices, by creating a smoother and more uniform surface. Especially important for implants and prosthetics in contact with body tissues for extended periods. A smoother surface is less likely to harbour bacteria so lowering risks of infections in surgical settings.
Medical devices are often in contact with bodily fluids and sterilization processes. Smoother surfaces enhance corrosion resistance, ensuring they remain durable and safe over time. Surface smoothness also lowers friction and improves wear resistance, extending implant lifespan and maintaining the device’s effectiveness. Surface finishing also enhances mechanical properties such as fatigue strength, ensuring devices withstand the stresses they encounter within the human body.
Fintek also provide other ranges of OTEC machines and processes such as disc finishing and stream finishing which can be used in medical applications. To help you realise surface improvements, Fintek technicians will advise on the best machine and process to optimise surface quality, cost effectively.
