Milling and drilling in medical engineering
Medical implants, surgical instruments or medical devices: The areas of implementation for medical technology products cover a wide spectrum and are growing steadily. With materials as diverse as their applications in medical engineering, machining tools by HUFSCHMIED, due to their material-specific geometries, ensure the highest possible accuracy when processing workpieces.
The use of new, innovative materials in medical engineering is beneficial to a great number of people that are reliant on biomedical technology. HUFSCHMIED provides suitable process-optimised tools for the manufacturing of these assistive devices – perfectly matched to the material in question.
Tools for medical engineering are often specialised tools that are characterised by accurate repeatability and validated manufacturing processes. Various polymers, but also metals and alloys are being used for this purpose. Our product range contains special milling cutters and drills for the cost-effective and speedy production of these engineered components.
A great number of our clients already benefit from our long-standing expertise in the processing of a wide range of materials for medical engineering. Process-optimised milling and drilling tools by HUFSCHMIED are used, for example, in the manufacturing of knee prosthetics, dental implants, but also in the production of dialysis machines and pace makers and impress with their accuracy, speed and long service life.
- Polymers in medical engineering
In the field of medical implants, components made from plastics such as UHM/PE, PEEK or CRP are being used. For the processing of these we recommend torus milling cutters and copy mills, but also spiral and stepped drills. They guarantee a fibre-free, burr-free processing combined with a high surface quality.
- Metals in medical engineering
In the manufacturing of medical engineering products made from metal, highly durable processing tools are crucial. Apart from a long service life, this sector also attaches great importance to high machining volumes.
Surgical instruments made from stainless steel or implants made from titanium or high-strength alloys present special challenges for tools. Cobalt-chrome alloys for artificial hip joints, for example, are highly resistant against wear and corrosion. Since they are relatively hard and mechanically very stable, the machining tools used have to be perfectly tailored to the prevailing conditions, in order to prevent a short service life. A cutting edge, for example, has to be positioned accurately to prevent notch wear.
Blade geometries and blade material are also critical for the processing of titanium. Apart from a perfect cut, a favourable chip formation must also be guaranteed. Furthermore, the temperature may not rise too much, since titanium, at high temperatures, enters a chemical reaction with the cutting material of the insert and releases heat largely onto the tool used. The solution here lies in the correct cutting speed and appropriate feed rate.
