1. Installation points
The directional key needs to be cleaned and deburred before installation
The clearance between the blade and the body is less than 0.01mm, ensuring stability and no looseness
Multi directional key installation angle error<1° Ensure even support
2. Adaptation of processing parameters
Cutting speed: The hard alloy guide key can withstand speeds of over 100m/min, while the nylon material can withstand speeds of 30m/min
Feed rate: The larger the width of the guide key, the higher the feed rate can be appropriately increased (but not less than 0.1mm/r)
Cooling pressure: 5MPa, ensuring that chips are not blocked and cooling is sufficient
3. Monitoring and replacement
Regularly check the wear of the guide key (measure the thickness with a micrometer)
When the wear amount is greater than 0.05mm, it must be replaced, otherwise it will affect the straightness of the hole
It is recommended to check once after processing 50-100 pieces, especially when processing hard materials
