5.Analysis of practical skills for CNC machining of solenoid valve parts
(1) Reasonable selection of tools:
Select appropriate tools according to the material and processing requirements of the solenoid valve parts. For example, when machining materials with higher hardness, select carbide tools with good wear resistance, and use coating technology to increase tool life. For machining of small parts, select small diameter tools to ensure machining accuracy.
(2) Optimize machining procedures:
Optimize machining paths through reasonable programming to reduce idle tool time and tool wear. Use high-speed machining technology to improve machining efficiency and surface quality. Appropriate use of subroutines and macro programs to simplify programming and improve machining consistency.
(3) Control cutting parameters:
Reasonably set cutting speed, feed rate and cutting depth to avoid tool damage or part quality problems caused by improper parameter selection. For thin-walled parts, the cutting depth and feed rate should be appropriately reduced to prevent deformation.
(4) Use efficient clamping methods:
Use special fixtures or combined fixtures to reduce clamping time and improve positioning accuracy. Ensure the stability of parts during processing to avoid vibration affecting processing quality.
