The safe technical operation of the grinding process of the centerless grinder is particularly important, and it is necessary to adopt a reliable safety protection device.
The operation must be concentrated to ensure that it is foolproof. In addition, the fine sand and metal shavings splashed from the workpiece of the grinding wheel during grinding will hurt the eyes of workers.
Workers who inhale this kind of dust in large amounts are harmful to their health, and appropriate protective measures should also be taken. The following safety technical issues should be paid attention to when grinding.
Before starting the centerless grinder, you should carefully check the machine tool, including checking the manipulation organization, electrical equipment, and magnetic suction cups.
After checking, it is smoothed and tested after being smoothed to confirm that everything is outstanding before use.
When installing the workpiece on the centerless grinder, pay attention to the correctness and clamping. The loosening of the workpiece during the grinding process will cause serious consequences such as the workpiece flying out and hurting the grinding wheel.
When starting the operation, use manual adjustment methods to make the grinding wheel slower and approach the workpiece. The starting feed should be small, and no excessive force is allowed to avoid bumping the grinding wheel.
When it is necessary to use the stop iron to control the reciprocating movement of the worktable, it must be accurately adjusted according to the grinding length of the workpiece to tighten the stop iron.
When replacing the grinding wheel with a centerless grinder, it is necessary to check the appearance to see if there is any trauma, and then strike it with a wooden hammer or wooden stick. The sound is required to be crisp and without cracks.
When installing the grinding wheel, it is necessary to assemble it according to the prescribed methods and requirements. After the static balance debugging, the device and the test run can be used after all are normal.
Workers of centerless grinders should wear protective glasses during the operation, and they should be balanced when dressing the grinding wheel to avoid collisions.
Measure the workpiece, adjust or wipe the machine tool after stopping.
When using a magnetic chuck, wipe the surface of the disk and the workpiece, close it tightly, and suck it firmly. If necessary, add a stopper to prevent the workpiece from shifting or flying out.
Pay attention to installing the protective cover of the grinding wheel or the baffle of the machine tool, and stand by the front of the high-speed rotating grinding wheel.
Operating Regulations of Centerless Grinder
1. It is necessary to correctly install and fasten the grinding wheel and guide wheel. It is necessary to ensure that the new grinding wheel and guide wheel are free from cracks or damage before the installation.
And pass the static balance test, after the rough repair, remove it and rebalance the machine for fine repair before it can be put into use;
2. Check whether the hydraulic lubricating oil meets the requirements before going to work. If the oil level is lower than the oil standard, add it in time before starting the machine tool. The machine can process workpieces without exception for about 10 minutes.
3. The grinding wheel spindle and guide wheel spindle must be smooth and normal before starting. It is found that the smooth light is not on and the pressure of the grinding wheel spindle is lower than 0.4Mpa.
It is necessary to find relevant personnel in time to analyze the cause and eliminate the fault. If the grinding wheel needs to be removed during repair,
After the repair is completed, it is necessary for the operator of the equipment to re-test the static balance of the grinding wheel. Recommended reading: What are the common problems of centerless grinders?
After the inspection and adjustment meet the requirements, the device is on the machine, the lock nut is locked in place and idling for about 10 minutes before there is no abnormality before the fine grinding wheel can be put into use. D
