Application hybrid CBN grinding wheel for medical stainless cutting tools

New requirements for precision tools in the medical industry
Difficult-to-machine materials, complex workpiece shapes and frequent small-batch production place high demands on the tools used to process medical materials. The precision tools produced by Walter enjoy a high reputation in this field.
Medical materials, such as implant products and prosthetics, play an important role in successful surgical procedures, helping surgeons achieve optimal medical outcomes. Cutting tools for processing medical materials determine the quality of medical materials to a large extent. The use of cutting tools in the manufacture of medical materials is diverse and extensive. It can process relatively simple workpieces such as large-scale equipment (such as computerized tomography cameras), while the production of implanted products or workpieces used to repair the skull or treat fractures. more challenging.

Precision – the most basic requirement
Tolerances in the micron range are common in the medical industry, and selecting the correct tool requires insight and experience. On the one hand, even drilling small holes requires the use of lubricants to reduce friction, reliably dissipate heat and dispose of fine iron filings at the cutting edge; cutting tools for high-quality surfaces. Commonly used cutting tools are high-speed steel drills or solid carbide drills. Walter Titex (Walter Titex) drill bit of Walter Group in Germany is used for processing difficult-to-machine materials such as titanium, stainless steel, precious metals and even composite materials. The diameter of the drill bit can reach 0.75mm.
Milling and Drilling – Dental Restoration
In the material selection of orthopedic cutting tools , stainless steel cutting tools occupy a large part. The grinding problem of stainless steel cutting tools is placed in front of the processor. The slotting of the cutting tools is the process with the largest machining allowance and the most time-consuming. For this application, we have developed a grinding wheel specially for stainless steel tool grooving, and conducted a series of experimental tests. The specific test results are as follows:
