If the cutting depth and feed are too large, it will increase the cutting resistance and acceleratetitanium alloy milling cutterof wear. Therefore, the choice of appropriate cutting parameters can also extend the life of titanium alloy milling cutter.

A larger rake angle results in less chip deformation, lighter cutting, lower cutting resistance and cutting heat. Titanium alloy milling cutter in the premise of ensuring sufficient strength, the rake angle should be as large as possible. Reducing the entry angle will increase the length of the cutting edge involved in cutting, so the relative distribution of cutting heat, cutting temperature may decrease as the tip angle becomes larger.

If the titanium alloy milling cutter has abnormal wear or rapid wear caused by chipping, the cutting tool should be selected and the cutting parameters should be changed. In order to increase the strength of the tool, it is also effective to use a negative rake angle geometry and select a fine cemented carbide material with high hardness.

The modification of cutting conditions is to reduce the amount of cutting first, rather than greatly reduce the feed rate. In order to maintain the wear resistance of the tungsten milling machine and obtain a good surface finish, it is important to choose a high cutting speed instead of a low cutting speed. Reduce the amount of cutting, to achieve stable processing of high-speed milling machine.

Through vibration analysis, the cutting state of the attachment can be grasped and adjusted in time to providetitanium alloy milling cutterPrepare the working environment. After replacing the titanium alloy milling cutter, the size should be adjusted to ensure the correct fastening and cutting conditions.

Precautions for the use of titanium alloy milling cutters are as follows:

1. Titanium alloy milling cutter blade milling cutter is made of the whole piece of tungsten steel, the cutting edge is sharp and sensitive. Therefore, in the process of moving, installing and removing the saw blade, care should be taken to protect the alloy head from damage.

2. Regularly check the radial runout (0.02mm) and swing (0.01mm) of the machine tool spindle.

3. Before installing the saw blade, it is necessary to clean the debris on the chu spindle and flange. Flange faces shall be flat and clean and perpendicular to the axis.

4. Using a flange with the largest possible ZUI can make the saw blade run more smoothly, and the flange size should be consistent. When the flange size is 1/3 of the diameter of the saw blade, the cutting effect is better.

5. After the saw blade is installed smoothly, it should be idling for 30 seconds, and then start cutting after everything is normal.

6. Titanium alloy milling cutter: When installing the saw blade, the flange nut needs to be tightened appropriately. If the saw blade is too loose, it will slip when rotating the cut. If the saw blade is too tight, there will be internal injury or deformation, which will affect the cutting effect.

7. Before cutting the saw blade, the operator needs to bring protective equipment (protective eye jing, dust mask, safety helmet, protective gloves) and check whether the saw blade cover is in good condition.

8., regularly deal with the resin, debris and other debris gathered on the side of the sawtooth and saw plate, because the accumulation of glue will increase the resistance, resulting in high energy consumption (in bad cases will cause the machine motor to burn), the cutting quality is rough. At the same time, if the cutting edge is blunt, it may cause sawtooth damage.

　　9.titanium alloy milling cutter: When cleaning, avoid using corrosive solvents. When the saw blade is not used for a long time, it should be cleaned and ground quickly, oiled to prevent rust, and then put it into the original carton.
