Refractory materials, complex workpiece shapes and frequent small batch production put forward high requirements for cutting tools used in processing medical materials. Walter's precision cutting tools have a high reputation in this respect.
Medical materials, such as implants and artificial limbs, play an important role in successful surgery, helping surgeons to achieve the best medical results. The quality of medical materials is largely determined by the cutting tools used in processing medical materials. The use of cutters in the manufacture of medical materials is diverse, from simpler parts such as the shell of large equipment (such as computerized tomography) to more challenging parts for transplantation or for the repair of skull bones or the treatment of fractures.
Precision -- the most basic requirement
Tolerances in the micron range are common in the medical industry, and choosing the right tool requires keen insight and a lot of experience. On the one hand, even if drilling holes also need to use lubricants to reduce friction, heat and reliably handle the blade of the fine iron chip; On the other hand, when producing cutting-edge (burr-free) medical materials, sharp, smooth cutting tools are needed to achieve high quality surfaces. Commonly used cutting tools are HSS bits or solid carbide bits. Walter Titex drill bits from Walter GmbH are designed to process refractory materials such as titanium, stainless steel, precious metals and even composites. The standard size of the drill center hole is 0.05-46mm, and the diameter of the intercooled drill bit is 0.75mm.
Milling and drilling - dental repair
As a standard, Walter Prototyp's ProtoStar series of monolith carbide tools have diameters ranging from 0.3 to 20mm. Located in Germany, Pratt is a well-known supplier to the medical industry. Its tap and thread milling cutters are mainly used for machining titanium alloys, such as bone screws or hip joints. The thread milling cutters with a diameter of 1.6mm can also be used to produce dental prostheses.
Turning tools for manufacturing transplanted products
Although Walter has been involved in the medical industry for a long time, the classic application of its products is mainly in some small size medical devices that require extremely high precision (such as bone screws and implanted tubes). Indexable carbide inserts WSM10, WSM20 and WSM30 are mainly used in multi-axis machine tools. Tiger- Tec? The coating and microcrystalline matrix provide maximum stability for the process, the heat-resistant Al2O3 coating provides maximum high temperature hardness and wear resistance, and the sharp cutting edge ensures the product is free of burr and chip build-up. Since titanium is one of the most frequently processed materials in the medical industry, new geometric shapes NFT, NMT and NRT are used to process titanium. NFT for fine machining, NMT for medium precision machining, and NRT for rough machining, these blades can be easily combined with a tool system such as Walter Shaft XLDE for user operation.
Custom composite tool solutions save time and money
Companies in healthcare, like those in other industries, are facing increasing cost pressures. If a company wants to stand on the international stage with fierce competition, it must produce high quality products at low cost. For implant products (typically made of high-alloy steel, titanium, or titanium alloys), the specific materials and complex workpiece geometry present significant challenges to product accuracy.
For some processes, three standard tools may be required before, but now only one compound tool is needed, replacing the previous three processes with one process, thus saving time and cost.
