Determining the Machining Path
The machining path refers to the trajectory and direction of the tool relative to the workpiece during CNC machining.
1. It should ensure machining accuracy and surface roughness requirements;
2. The machining path should be shortened as much as possible to reduce tool idle travel time.
Relationship between Machining Path and Machining Allowance
Under conditions where CNC lathes are not yet widely used, excessive allowances on the blank, especially those containing forged or cast hard skin layers, should generally be machined on a conventional lathe. If CNC lathe machining is necessary, the program should be flexibly arranged.
Key Points for Fixture Installation
The connection between the hydraulic chuck and the hydraulic clamping cylinder is achieved by a pull rod. The key points for hydraulic chuck clamping are as follows: First, use a wrench to remove the nut on the hydraulic cylinder, remove the pull tube, and pull it out from the rear end of the spindle. Then, use a wrench to remove the chuck fixing screws to remove the chuck.
