What is the basic operation way of the grinding machine?
Before using the grinder, you should check whether the machinery, screws, electrical appliances, guards, dust-absorbing devices, work cards and gauges are firm and must be intact.
After checking each part by hand, check the longitudinal reciprocating motion of the grinding head, and confirm that it is normal, then you can work. Before working, manually adjust the position of the commutator block iron according to the grinding length of the workpiece, and tighten it.
When the machine tool is working, the pressure of the hydraulic system should not exceed the specified value range. The oil temperature should not exceed 50℃. When there is air in the cylinder the grinding head should be exhausted by traveling back and forth several times. Grinding machine compound angle control table.
There is no automatic and manual interlocking mechanism for the longitudinal movement of the machine. When using hydraulic automatic reciprocating motion, the handle must be pulled.
The tightness of the fixture and workpiece, the balance tightness of the grinding wheel and the belt tightness should be checked frequently during work. Dull grinding wheel should be repaired in time.
When trimming the grinding wheel, the diamond knife is fixed on the special bracket. Operation is strictly prohibited impact, wear protective glasses.
When the grinding wheel is not separated from the workpiece, stopping is not allowed.
The replacement of the grinding wheel should follow the general safety regulations of the grinder.
Do not touch the workpiece when grinding, and do not transfer things across the moving parts.
Adjustment, repair, lubrication, wiping, etc. with machine tools should only be done in a stopped state.
Carefully implement the following general rules for grinding machines CNC Surface Grinder Usage.
The installation of the new grinding wheel must be done:
Hand grinding machine processing skills and methods.
1. Carefully inspect the new grinding wheel, it is strictly prohibited to use if there are cracks and scars. Hand crank grinder starter tips.
2. the new grinding wheel should be after two serious static balance, that is, once before installation, after the spindle is installed with diamond correction once, remove the balance.
When installing a new grinding wheel, a 0.5~2mm paper pad should be padded between the grinding wheel and the flange. The flange screws should be tightened evenly, but do not over-compress, so as not to crush the grinding wheel.
After the new grinding wheel is installed, run it at the working speed for not less than 5 minutes to confirm that it is installed correctly and operates normally before working. Before work should check the grinding wheel and grinding wheel cover should be intact, no cracks, installed correctly, fastened reliably. The machine is not allowed to start without grinding wheel guard. Zhongyi Surface Grinder products have excellent features such as high precision, high stability, high cost performance and so on. It is the processing mother machine production and manufacturing enterprise of social modernization production.
Precautions for machining workpieces on different grinding machines:
Cylindrical grinder: Before starting the grinding wheel, the reversing handle must be placed in the position where the grinding wheel leaves the workpiece to avoid accidents.
Surface grinding machine:
1. The disk switch must be turned on before work, the suction force of the disk should meet the requirements, and the interlocking device between the disk and the grinding wheel startup should be reliable and easy to use.
2. When placing the workpiece, the disk must be wiped clean. For grinding high or small bottom area workpieces, a block of suitable height (generally 3-5 mm lower than the workpiece) must be added to move the workpiece and check whether it is firmly suctioned.
3. Grinding thin iron plates is not allowed. It is not permitted to grind the end face of the workpiece with a grinding wheel on a grinder that does not have an end face grinding structure.
Tool grinding machine:
The rotational speed of the grinding wheel should be selected according to the diameter of the grinding wheel before working: when the diameter of the grinding wheel is more than millimeters, the rotational speed should be rpm; when the diameter of the grinding wheel is less than millimeters, the rotational speed should be rpm.
Inserts grinding machine:
1. When grinding and pulling, it must be ground from the center. After grinding in the middle, mount the center frame and grind the remaining teeth.
2. The longitudinal displacement of the grinding wheel holder shall be clamped while grinding.
Circular saw blade grinding machine:
According to the number of teeth and height of the saw blade, after adjusting the travel of the crane wheel and the grinding wheel, pull the pulley by hand to check whether there is any collision between the grinding wheel and the saw teeth.
Guideway grinding machine:
1. New grinding wheels that have been statically balanced still need to pass a fracture test. During the test, increase the speed to 25-50% of the rated speed and run for 15-20 minutes.
2. The carriage should not be raised manually or electrically until the carriage oil pressure balance switch is turned on.
3. Do not drive the reciprocating table when the oil storage capacity in the oil tank is lower than the rated capacity specified in the oil label, so as to avoid a large amount of air entering the oil circuit system.
