Coated insert for processing titanium alloy medical parts

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

Titanium alloys are more difficult to machine than the familiar iron metals and aluminum alloys. We can think of it as a kind of stainless steel, but its higher strength, fiberized chips, are more likely to chip at the cutting and cutting points of the tool. Carbide tools do not require coating, because processing titanium alloys does not have the same chemical reaction as processing iron, but it must be sharp. In order to prevent overheating during high speed machining, PVD coated inserts such as IC908-IC907-IC1008 are recommended.

ISCAR has developed a range of small part processing inserts specifically for titanium alloys. Their common feature is that they have very sharp edges, ground or finely ground surfaces for super-light surface finish without built-up edge . In fact, it is available in the hard alloy IC908, which has been used in the aerospace industry for decades. Up to now, ISCAR has a line of small-titanium alloy processing, including an ultra- sharp edge end mill with a bowl-shaped and ground surface; the overall carbide drill diameter is as small as 0.8mm, with machined steel The groove type of the piece and the reamer groove type for processing titanium alloy; four blades with aggressive WF or MD chipbreaker and JETCUT cutting blade for processing titanium alloy; the TANG-GRIP weight for processing titanium alloy is about to be introduced Load the self-clamping grooving knife.
