A team of specialists from the PAFANA company has comprehensively developed a new technology for efficient treatment of medical devices from titanium alloys, which can be used in the production of other, complicated details from these materials, e.g. aviation parts
Based on the experience gathered at PAFANA during the implementation of implants, guidelines for the construction of monolithic carbide milling cutters intended for the machining of titanium alloys were developed
Summary
The effect of R&D works covered by the project entitled „Designing the surface structures of individual medical implants, produced in hybrid technology using a laser head”, implemented as part of the Smart Growth Operational Programme No POIR.01.01.01. The technology of waste machning of implants from medical titanium alloys has been improved and the technology of laser surface modification of the implant has been developed. The first was to increase the machining efficiency of titanium alloys thanks to the design of new cutting tools and new machining methods using: a 70 bar coolant, high cutting forces, a rigid system (suitable for slender items) and optimized tool paths. The processing efficiency increased more than 10 times, and the technical cost of manufacturing has decreased. The second goal was to modify the surface of the implant using a laser, which resulted in a greater biocompatibility (by 5÷10% better osseointegration) compared to the unmodified reference surface
