The birth of coated blades for the processing of titanium alloy medical parts

In the medical parts manufacturing industry, the main difference is that more than 90% of implants are made of titanium alloy Ti6Al4V, which is an unfamiliar metal for this industry. Although some stainless steels are also used, surgeons prefer titanium alloys because of its strength-to-weight ratio and better adhesion to human tissues.

Compared with the iron group metals and aluminum alloys that we are familiar with, titanium alloys are more difficult to machine. We can think of it as a kind of stainless steel, but with higher strength, fibrous chips are more prone to chipping at the cutting-in and cutting-out points of the tool. Cemented carbide tools do not require coating, because processing titanium alloys does not have a chemical reaction like processing iron, but the cutting edge must be kept sharp. In order to prevent overheating during high-speed processing, it is recommended to use PVD-coated inserts, such as IC908-IC907-IC1008.

ISCAR has specially developed a series of small parts processing blades for titanium alloys. Their common feature is that they have very sharp cutting edges, grinding or fine grinding surfaces, so as to obtain super-gloss surface finish without producing Built-up tumor. In fact, it can provide cemented carbide IC908 material, which has been popular in the aerospace industry for processing titanium alloys for decades. So far, ISCAR has a product line of small parts titanium alloy processing, including a super-sharp edge end mill, which has a bowl-shaped and ground surface; solid carbide drills have a diameter as small as 0.8mm and have a machined steel The geometry of parts and the reamer geometry for processing titanium alloys; four types of turning inserts with aggressive WF or MD chipbreakers and JETCUT cutting tools for processing titanium alloys; the upcoming TANG-GRIP for processing titanium alloys Self-clamping grooving knife with vertical mounting.
