Be proficient in controlling the manual or automatic operation of CNC lathes, and be proficient in controlling the movement of each CNC axis of the lathe. The operator must reach the realm of practice makes perfect, then he can be able to retract freely under any circumstances; only in the event of a collision or failure, the operator can deal with the problem correctly and in a timely manner, and the operator will form a conditioned reflex and take decisive action.
Proficient in the program, each process parameter compensation tool or grinding wheel diameter and length compensation. First, after training, master the programming language of the CNC lathe you want to operate, and the compensation method of each parameter of the programming method. Most advanced CNC lathes are now equipped with programming or simulation PC workstations. Then beginners can first perform software editing and lathe cutting simulation learning on the workstation.
The actual processing skills of the processing process, carefully prepare the work, first read the drawings, confirm the position of the workpiece to be processed, confirm the accuracy tolerance of the workpiece to be processed, and then edit the processing program. To prepare the workpiece tool or grinding wheel for processing, prepare all the inspection instruments required for the processing process, and prepare all the auxiliary tooling fixtures required for the processing process.
First, check the working conditions of electrical, hydraulic, lubrication and control systems.
Second, check the operation of all levels of rotational speed from low to high and the idle travel of each moving part. Third, within 200 hours of initial use, the weight of the workpiece should not exceed 50% of the allowable load of the workbench, the highest two-stage speed of the workbench should not be used, and the cutting force should not exceed 50% of the maximum cutting force.
Fourth, change the oil once after the initial operation for one month, and change the oil once in three months or six months after the operation.
Precautions during use
First, pay attention to check the position of the handle before work and whether the jaws are clamped to the workpiece.
Second, check the cleanliness of the guide rail lubrication.
Third, check whether the signal light and the interlocking device are sensitive and reliable.
Fourth, check whether the moving parts enter the limit position and whether the screws are loosened before moving. Fifth, when the worktable is not stopped, no mechanical speed change is allowed, but the stepless speed regulation part of the feed movement and the main movement can be adjusted at any time as needed.
Sixth, 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.
Seventh, do not stop before the tool is withdrawn.
Maintenance and maintenance of machine tools during packaging and long-term storage. 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.
