Five Principles of Processing Titanium Alloy Parts

Five major principles of titanium alloy parts processing have recently been discussed by many professionals on the Internet. In order to help you understand this knowledge clearly, the following information has been compiled to share with you:


Five Principles of Titanium Alloy Parts Processing:

1. Cutting speed:

Cutting speed is an important factor affecting cutting edge temperature. Excessive cutting speed will lead to excessive heat, adhesion and diffusion wear of the cutting edge, frequent tool re-grinding, and shorten tool life. At the same time, it will lead to surface cracking or oxidation of titanium alloy workpiece, which will affect its mechanical properties. Therefore, under the premise of guaranteeing greater tool durability, appropriate cutting speed should be selected to reduce costs and ensure processing quality.

2. The depth of feed and the amount of feed:

The change of tool feed rate has little effect on temperature, so reducing cutting speed and increasing tool feed rate are reasonable cutting methods. If there are oxidized layer and subcutaneous porous layer, large cutting depth can be directly cut to the basic non-oxidized metal layer to improve tool life.

3. Geometric angle of cutter:

When cutting titanium alloy, choosing geometric parameters such as front angle and rear angle, which are suitable for processing method, and properly handling the tool tip will have an important impact on cutting efficiency and tool life.

Experiments show that in order to improve the heat dissipation condition and enhance the cutting edge, the front angle is usually 5 9 in order to overcome the friction caused by rebound, the back face of the tool body is generally 10 15 in order to overcome the friction caused by rebound. When drilling, the length of the bit is shortened, the thickness of the core and the guide taper are increased, and the durability of the bit can be increased several times.

4. Clamping force of fixture:

Titanium alloy is easy to deform and clamping force can not be too large. Especially in the finishing process, some auxiliary support can be selected.

Cutting fluid:

Cutting fluid is an indispensable process lubricant in titanium alloy processing. Cutting fluid can not only effectively reduce cutting temperature and heat generated by tool and cutting friction, but also act as lubricant in cutting process, reduce the bond between titanium alloy chips and tool surface, improve efficiency, reduce cost and prolong tool life. However, cutting fluids containing chlorine or other halogen elements and sulphur can not be used. Such cutting fluids will have adverse effects on the mechanical properties of titanium alloys.
