Machinery & Tools for medical devices

Manufacturing medical devices places demands on machinery and tools that go beyond precision. In demand are turn-mill centres and Swiss-type lathes for small, complex parts in titanium and stainless steel, grinding machines for instrument cutting edges, EDM machines for fine contours, plus tools, workholding and fixtures that stay reproducible over thousands of parts.

The decisive difference from other industries lies in validation. A machine on which medical devices are made is qualified — installation, operation, performance — and any significant change to machine, tool or program can trigger a new assessment. Anyone supplying a machine therefore ideally supplies the documents needed for this: specifications, acceptance records, calibration certificates for the measuring systems.

Then there are materials that shape machining. Titanium tends to gall and needs sharp edges and plenty of coolant; cobalt-chrome is tough and wears tools quickly; plastics such as PEEK require different geometries from metal. The providers listed here range from machine manufacturers and dealers through tool and fixture makers to service providers for maintenance and qualification.
