The usage method of the automatic lathe for turning the inner ring of rolling bearings involves multiple steps and details. The following is a guide based on standard operating procedures:
1、 Preparation work
Check equipment:
Ensure that the electrical wiring of the automatic lathe is securely connected and the switch is functioning properly.
Check if the lubricating oil is sufficient and turn on the lubrication system.
Confirm that the tool is securely installed, the tool size is correct, and the installation, wear level, and size of the grinding wheel meet the requirements.
Preparation materials:
Select bar materials that meet the requirements, ensuring that their dimensional tolerances, roundness, etc. meet the processing requirements of automatic lathes.
Straighten and perform centerless rough grinding on hot-rolled bars to remove surface defects.
2、 Clamping and positioning
Clamping rod material:
Load the bar material into the feeding mechanism of the automatic lathe, ensuring that the position of the bar material is correct and firmly fixed.
Positioning and adjustment:
Adjust the feed rate, feed speed, and cutting speed of the lathe according to the processing requirements.
Ensure that the spindle speed of the lathe matches the cutting speed.
3、 Turning machining
Start the lathe:
Turn on the power switch and start the automatic lathe.
Turning process:
The lathe will automatically cycle the bar material and perform turning according to the preset program.
During the turning process, it is necessary to closely monitor the operating status of the lathe to ensure a smooth and normal machining process.
Monitoring and adjustment:
Adjust the feed rate, feed speed, and cutting speed of the lathe in a timely manner according to the processing progress and workpiece quality.
If the lathe is found to be running abnormally or the workpiece quality does not meet the requirements, it should be stopped immediately for inspection and adjustment.
4、 Complete processing and testing
Stop the lathe:
After processing, turn off the power switch of the lathe.
Remove the workpiece:
After the lathe comes to a complete stop, remove the processed inner ring of the rolling bearing.
Quality inspection:
Use measuring tools such as vernier calipers and external micrometers to conduct quality inspections on the processed inner rings of rolling bearings, ensuring that their dimensional tolerances, roundness, and other requirements are met.
5、 Maintenance and upkeep
Cleaning the lathe:
After processing, clean the worktable, cutting tools, and grinding wheels of the lathe in a timely manner to remove residual cutting chips and oil stains.
Lubrication and maintenance:
Regularly maintain and upkeep the lubrication system of the lathe to ensure sufficient and clean lubricating oil.
Regularly check the wear of the lathe's cutting tools and grinding wheels, and replace severely worn components in a timely manner.
security check:
Regularly conduct safety inspections on the lathe to ensure the normal operation and safety of electrical circuits, switches, and other components.
In summary, the use of the automatic lathe for turning the inner ring of rolling bearings involves multiple steps and details, requiring operators to be proficient in the operation process and precautions to ensure a smooth, efficient, and safe machining process. At the same time, regular maintenance and upkeep of the lathe is also an important measure to ensure machining quality and extend the service life of the lathe.
