Processing of titanium alloy parts, a lot of processing technology in the hardware processing industry. Recently, there has been a wave of enthusiasm on the Internet. Many large, medium and small enterprises related to this processing are more interested in this knowledge.

I mainly want to know what are the principle problems in the processing of titanium alloy parts. Let's take a look!

Five principles for the processing of titanium alloy parts

First, the clamping force of the fixture

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

Second, the depth of the infeed and the amount of cutting

The change in the amount of the cutter does not change much in temperature, so reducing the cutting speed and increasing the amount of the cutter is a reasonable cutting method. If there is an oxide layer and a subcutaneous pore layer, the large depth of cut can be directly cut into the substantially unoxidized metal layer to improve the life of the tool - titanium price - titanium periodic table - titanium sheet.

Third, the cutting speed

Cutting speed is an important factor affecting the temperature of the blade. Excessive cutting speeds can lead to overheating of the blade, severe blade edge and diffusion wear, and frequent tool regrind, which can shorten tool life.

At the same time, the surface layer of the titanium alloy workpiece is cracked or oxidized, which affects its mechanical properties. Therefore, under the premise of ensuring greater tool durability, the appropriate cutting speed should be selected to reduce the cost and ensure the processing quality.

Fourth, the geometric angle of the tool

When cutting titanium alloys, selecting geometric parameters such as rake angle and back angle that are compatible with the machining method and proper treatment of the tool tip will have an important influence on cutting efficiency and tool life.

Tests have shown that in order to improve the heat dissipation conditions and enhance the cutting edge during turning, the rake angle is generally 5 ° ~ 9 °; in order to overcome the friction caused by rebound, the flank of the cutter body is generally taken 10 ° ~ 15 °; When drilling,

By shortening the length of the drill bit, increasing the thickness of the core and the amount of the guide cone, the durability of the drill bit can be increased several times.

Five, cutting fluid

Cutting fluid is an indispensable process lubricant in titanium alloy processing. The cutting fluid not only effectively reduces the cutting temperature, reduces the heat generated by the tool and cutting friction, but also acts as a lubricant for the cutting process.

Reduce the bonding of the titanium alloy chip and the tool face, improve efficiency, reduce cost and extend tool life. However, it is not possible to use cutting fluids containing chlorine or other halogens and sulfur. Such cutting fluids can adversely affect the mechanical properties of titanium dioxide alloys.
