What are the precautions for the initial use of CNC vertical lathes
CNC vertical lathe is an advanced equipment with excellent performance, wide range of processes and high production efficiency.
Preparation and precautions for the initial use of CNC vertical lathes:
1. Check the working conditions of electrical, hydraulic, lubrication and control systems.
2. Check the operation of all levels of rotational speed from low to high and the idle travel of each moving part.
3. Within 200 hours of initial use, the weight of the workpiece should not exceed 50% of the allowable load of the worktable, the highest two-stage speed of the worktable should not be used, and the cutting force should not exceed 50% of the maximum cutting force. The pressure plate should not be adjusted too tightly, and the ram should not stick out too long.
4. Change the oil once after the initial operation for one month, and change the oil once for three months or six months after the operation.
Precautions during the use of CNC vertical lathes:
1. Before driving, pay attention to check the position of the handle and whether the claws are clamped to the workpiece.
2. Check the cleanliness of the guide rail lubrication.
3. Check whether the signal light and the interlocking device are sensitive and reliable.
4. Check whether the moving parts enter the limit position and whether the screws are loosened before moving.
5. When the worktable is not stopped, it is not allowed to perform mechanical speed change, but the stepless speed regulation part of the feed movement and the main movement can be adjusted at any time as needed.
6. When lifting the workpiece, 80 oil pump motors should be stopped first, so as to avoid the sudden increase of oil pressure when the lifting workpiece is unstable and damage the pressure gauge of the feedback valve.
7. Do not stop before the tool is withdrawn.
8. When the machine tool is packaged and stored for a long time, the exposed machined surface should be coated with anti-rust agent. If the oil seal period is exceeded, the oil seal should be re-sealed.
