Attention should be paid to during milling

When milling, be careful not to get too close to the machine tool to avoid being scalded by high-temperature iron filings; Do not clean the workpiece being processed with a brush; Don't put your hands near the rotating milling cutter.

Characteristics of milling process:

1, high productivity When milling, the milling cutter rotates continuously, allowing high milling speed, so the productivity is high.

2. In intermittent cutting and milling, every cutter tooth is cutting intermittently, especially in end milling, the milling force fluctuates greatly, so vibration is inevitable. When the vibration frequency is equal to or several times the natural frequency of the machine tool, the vibration is the most serious. In addition, during high-speed milling, the cutter teeth are subjected to periodic cold and hot shocks, which are prone to crack and edge collapse, reducing the tool durability.

3. Multi-tool multi-edge cutting milling cutter has many teeth and the cutting edge always grows, which is beneficial to improve the tool durability and productivity and has many advantages. However, there are also two problems: first, the cutter teeth are prone to radial runout, which will cause uneven stress and wear of the cutter teeth and affect the quality of the machined surface; Secondly, the chip space of the cutter tooth must be sufficient, otherwise it will damage the cutter tooth.

4. Different milling methods According to different processing conditions, in order to improve tool durability and productivity, different milling methods can be selected, such as reverse milling, forward milling or symmetric milling and asymmetric milling.
