Reason 1 The use of the tool itself does not match the machine settings, to be adjusted. Solution: adjust the speed and speed ratio (generally transferred to about 10: 1) made when the domestic machine to reduce the rotational speed when appropriate 2 processing material excellent. Solution: It is recommended to use a coating or PCD blade. That is, the center of gravity offset, so the rotation of a larger centrifugal force resulting in vibration when rotating more than double-edged tools, solution: to reduce the gripper position that is to be shortened to the bottom of the chuck exposed length. 2 crankshaft chuck grasping knife instability, resulting in vibration.
In the process of economic CNC machine tool, because the tool sharpening, measurement and replacement are mostly manual and take a long time auxiliary, therefore, must arrange the order of the cutter reasonably. Generally follow the following principles:

1. Minimize the number of tools
2. After a tool is clamped, it should complete all its processing steps;
3. Crude finishing tools should be used separately, even if the same size of the tool;
4 before drilling after drilling;
5. First surface finishing, after two-dimensional contour finishing;
6. Where possible, should be used as far as possible CNC machine tool automatic tool change function, in order to improve production efficiency.
Milling aluminum mainly has the following major features;

1, aluminum alloy hardness is low
Compared with titanium and other hardened steel, aluminum alloy hardness is lower, of course, heat treatment, or die-casting aluminum alloy is also very high hardness. Ordinary aluminum HRC hardness are generally HRC40 degrees below. Therefore, the processing of aluminum alloy, the cutter load is small. Because of the better thermal conductivity of aluminum alloy, milling aluminum alloy cutting temperature is relatively low, can increase its milling speed.
2, low plasticity of aluminum alloy
Aluminum plastic low, low melting point. When processing aluminum alloy sticking knife when the problem is serious, poor chip performance, surface roughness is relatively high. In fact, the main processing aluminum alloy knife and roughness is not good. As long as the solution to the stick knife, the quality of the two surface processing problems, aluminum processing problems to be solved.
3, easy to wear knives
Because it is not suitable for cutting tool materials, aluminum processing, often because of sticky knife, chip removal and other issues lead to accelerated tool wear.
