アイテック List of Products and Services

We would like to introduce a case study of "deep hole machining of titanium (Ti)" conducted at Aitec Co., Ltd. Difficult-to-machine materials such as high-hardness materials, sintered materials, titanium, and Inconel often have limited data on tool types and cutting conditions, making them less appealing to machinists. At our company, we first determine the types of tools to be used and the cutting conditions before proceeding with the machining. One of the challenges we faced in this machining process was that the deep hole machining of a φ1.5mm diameter and 50mm depth was a blind hole. 【Case Overview】 ■ Work Size ・Φ18mm × 65mm ・Deep hole machining of φ1.5mm at 50mm depth ■ Material: Titanium alloy *For more details, please refer to the PDF document or feel free to contact us.

The three main characteristics of "Titanium (Ti)" as a metal material are said to be "light," "strong," and "corrosion-resistant." However, when machining, its excellent material properties can lead to problems such as shortened tool life and an increased tendency for chips to ignite, positioning it as a difficult-to-cut material. Additionally, it has poor thermal conductivity, and there is a tendency for alloying with the main components of cutting tools at cutting temperature ranges, as well as a stronger tendency to undergo chemical reactions. Therefore, it is necessary to use cutting machines with high rigidity and appropriate tools while simultaneously taking measures to reduce cutting speed and lower cutting temperatures.
