The safety technology operation of the grinding process of the centerless grinder is particularly important, and it is necessary to adopt reliable safety protection devices,
The operation should be focused on ensuring that there is no mistake. In addition, the fine sand and metal shavings splashed out from the workpiece of the grinding wheel during grinding can harm the eyes of workers,
If workers inhale a large amount of this dust, it is harmful to their bodies and appropriate protective measures should also be taken. When grinding, the following safety technical issues should be noted.
Before driving the centerless grinder, a comprehensive inspection of the machine tool should be carried out carefully, including inspection of the operating organization, electrical equipment, and magnetic suction cups and other fixtures.
After inspection and smoothing, conduct a test run to confirm that everything is outstanding before use.
When installing workpieces on a centerless grinder, attention should be paid to aligning and tightening them. During the grinding process, if the workpiece becomes loose, it may cause serious consequences such as flying out and injuring people or crushing the grinding wheel.
When starting homework, manual adjustment should be used to make the grinding wheel slowly approach the workpiece. The initial feed rate should be small, and excessive force should not be used to avoid hitting the grinding wheel.
When it is necessary to use a blocking iron to control the reciprocating movement of the worktable, it should be accurately adjusted according to the grinding length of the workpiece, and the blocking iron should be tightened firmly.
When replacing the grinding wheel with a centerless grinder, it is necessary to inspect the appearance to see if there is any external injury, and then use a wooden hammer or stick to strike, ensuring that the sound is clear and there are no cracks.
When installing the grinding wheel, it is necessary to assemble it according to the prescribed methods and requirements. After static balance debugging, the device can be installed and tested. Only after everything is normal can it be used.
Workers without a center grinder should wear protective goggles during operation, and balance the grinding wheel to avoid collisions.
Measuring the workpiece, adjusting or wiping the machine tool must be carried out after shutdown.
When using a magnetic suction cup, the surface and workpiece should be wiped clean, tightened, and firmly sucked. If necessary, a blocking iron can be added to prevent the workpiece from shifting or flying out.
Pay attention to installing the grinding wheel protective cover or machine tool baffle, and stand on the side past the front of the high-speed rotating grinding wheel.
Operating procedures for centerless grinding machines
1. It is necessary to correctly install and tighten the grinding wheel and guide wheel, and it is necessary to ensure that there are no cracks or damage to the new grinding wheel and guide wheel before installation,
And it can only be put into use after undergoing static balance testing, rough trimming, and then removing it for re balancing and installation;
2. Before starting work, check if the hydraulic smooth oil meets the requirements. If the oil level is below the oil mark, add it in time before starting the machine tool.
Only when the machine tool is idle for about 10 minutes without any abnormalities can the workpiece be processed.
3. The grinding wheel spindle and guide wheel spindle must be smooth and normal before starting. If the smooth light is not on and the grinding wheel spindle pressure is below 0.4Mpa,
It is necessary to promptly seek relevant personnel to analyze the cause and eliminate the fault. If the grinding wheel needs to be removed during repair,
After repair, it is necessary for the equipment operator to perform a static balance test on the grinding wheel again. It is recommended to read: Common problems with centerless grinders
After the inspection and adjustment meet the requirements, the device should be put on the machine. The locking nut should be locked in place and idle for about 10 minutes without any abnormalities before the precision grinding wheel can be put into use.
