CNC titanium milling

Titanium milling is a difficult process due to the poor machinability of this material. One of the biggest challenges is proper heat dissipation. Relatively little heat is given off by the chip, so that most of the heat is absorbed by the tool. Due to this effect, special attention should be paid to the proper selection of cutting width and ensuring proper cooling of the tool.
The next aspect in the titanium milling process is the tool size. The 70 percent rule should be followed, i.e. the tool diameter should not exceed 70% of the pocket size. A smaller clearance will isolate the tool from the coolant and may cause chip clogging that could at least partially remove heat.

CNC titanium machining

Titanium is an element that due to its high mechanical strength, corrosion resistance and at the same time relatively low density is very widely used in industry. You can meet him, among others in aviation, automotive, defense industry and medicine.

Metallic titanium, however, is an expensive material due to the complicated process of preparation requiring the consumption of large amounts of energy and raw materials. For this reason, titanium alloys with iron, aluminum and nickel have become very popular, which allow you to increase the strength of the structure while reducing weight compared to traditional steels. In addition, titanium alloys are characterized by high strength at high temperatures.

When milling titanium and other metals using CNC, remember to gently insert the tool into the material. The most common reason for tool damage is a rapid load change when the tool is inserted directly. To avoid this, an arc entry should be used, which allows a gradual increase in cutting forces and prevents tool tearing and instability. In addition, the process of generating heat and chip production is graded to full engagement in the material.
