Operation requirements of CNC Grinding Machine
1. Operators are allowed to operate only after they have passed the examination and obtained the operation certificate.
2. Operators must familiar with the structure and performance of each part of the machine tool, the various solenoid valves, stroke switches and buttons on the operation panel, the function of indicator lights and the working cycle of the machine tool. What's more, it is also important for operators to abide the traffic safety and shift system.
3. According to the requirements of the Grinder Instructions, the operators must know and memorize the lubrication parts, lubrication methods, types and grades of lubricants in detail, and maintain the oil according to the rules of the Grinder Lubrication Chart.
Before starting the work
1)We should wear protective equipment according to the regulations, check every part of the grinder in detail, report the problems in time and step by step, and do not drive unless the abnormality is ruled out.
2)Check the injection condition of each tank, whether the oil quantity has reached the specified oil level height. Whether the oil tube is installed in place and firm, and whether the initial indication of pressure gauge is in zero position.
3)Adjust the belt to an appropriate status.
4)The grinding wheel shield and the grinding wheel should firmly clamp, position correctly. Besides, the working table guide shield should in close contact.
5)Check the lubricating parts, sliding surfaces and transmission system, and inject lubricating oil. Check the relative position of the diamond tip and grinding wheel of grinding wheel dresser to prevent collision accident.
6)Connect the power supply and start the motor of the oil pump, grinding wheel rack and bedside rack in turn, pay attention to the operating state. If the abnormal condition or abnormal sound is found, the power supply should switch off immediately.
7)Start the grinder and idle for 2 to 3 minutes to check whether the movements of each part are normal. If the mechanism fails, the bearings are overheated, the oil pressure is insufficient, the grinding wheel swings and the table move unsteadily, the power supply should cut off and measures take to deal with it.
8)Check whether the motor of the cooling pump is working properly and the coolant is unblocked.
During the installation process
1)Check the new grinding wheel carefully, if there are cracks or scars, it is strictly forbidden to use. And the new grinding wheel shall carefully balance twice, that is, once before installation, once after being corrected with diamond for the spindle.
2)When installing a new grinding wheel, the special paper cushion of 0.5-2 mm should insert between the grinding wheel and flange. Grinding wheel flange bolts must tighten even with a special wrench, and forbidden to tighten with lengthened pipes, so as to prevent the wheel from cracking.
3)After the new grinding wheel is installed, the protective door is closed and the idle operation is carried out at the working speed for not less than 5 minutes. The operator should avoid the front and confirm the correct installation. Only after the operation is normal, can the grinding wheel work.
4)After the new grinding wheel has correct and position memory has been done, it should test and correct according to the regulations. If there is any abnormity or collision, it should stop urgently and the position memory should restore.
