What special precautions should be taken when using the m1320h a transverse cylindrical grinding machine?

The M1320H horizontal cylindrical grinder is a high-precision machine tool that is widely used in the processing of small and medium-sized, diversified internal and external circles. In order to ensure the safety of operation and processing accuracy, the following matters need to be noted when using the M1320H horizontal cylindrical grinder:
1. Preparation before operation
Make sure that the machine tool is placed in a stable position and check whether the voltage meets the requirements. At the same time, check whether the machine tool circuit is intact to avoid wire wear or air leakage. According to the delivery configuration list, check whether the relevant configuration is complete, including grinding wheels, coolants, lubrication systems, etc. Select grinding fluids suitable for grinding workpieces to ensure processing quality and efficiency. Check whether the oil tank is filled with hydraulic oil and whether the guide rail oil is sufficient.
Select a suitable grinding wheel according to the processing material and grinding requirements. For example, when processing unquenched carbon steel, brown corundum A (GZ) can be selected for rough grinding, and F46~F60 grit abrasives can be selected for fine grinding. New grinding wheels must be carefully checked for cracks or scratches before use, and defective grinding wheels are strictly prohibited. When installing a new grinding wheel, insert a 0.5~2 mm paper pad between the grinding wheel and the flange, and ensure that the flange screws are tightened evenly and symmetrically. After installation, run it idle for no less than 5 minutes to confirm that the installation is correct and the operation is normal.
Before starting the grinding wheel each time, the hydraulic start-stop valve should be placed in the stop position, the adjustment handle should be placed in the lowest speed position, and the grinding wheel seat fast feed handle should be placed in the back position. At the same time, start the lubrication pump or the hydrostatic oil supply system oil pump, and the grinding wheel can only be started after the grinding wheel spindle is lubricated normally. When grinding starts, the feed amount should be small and the cutting speed should be slow to prevent the grinding wheel from breaking due to cold brittleness. During grinding, the distance between the grinding wheel and the workpiece should be adjusted to avoid collision between the grinding wheel and the workpiece. When the temperature of the grinding wheel spindle exceeds 60°C, the equipment must be turned off and work can only be resumed after the temperature returns to normal.
Before operation, tight protective clothing should be worn, the cuffs should be fastened, and the hem of the top should not be open. It is strictly forbidden to operate with gloves to prevent machine entanglement. The operator is prohibited from leaving the grinder during operation. If the operator must leave the grinder due to power outage or other reasons, the grinding wheel should be removed from the workpiece and then stopped. It is prohibited to knock, disassemble, or straighten the workpiece on the work surface and bed; it is prohibited to place metal objects on the work surface and painted surface; it is strictly prohibited to use compressed air to clean the equipment to prevent debris from entering the guide rail and affecting the service life of the machine tool.
Clean the machine surface, slides, guide rails, etc. regularly to avoid the influence of dust and debris on the normal operation of the machine tool. At the same time, clean the guide table, tailstock, workbench, probe and other accessories. According to the requirements of the equipment manual, regularly maintain and service the lubrication system of the grinder to ensure that each lubrication point is fully lubricated. Regularly check the wear and eccentricity of the grinding wheel, and clean up dust and sand and gravel debris. Check the wires, pipelines, transmission parts, coolant, etc. to ensure that the machine tool is in good condition. In case of mechanical failure, electrical failure or hydraulic failure, professional maintenance personnel should be notified in time for processing.
