The miniature bearing grinding machine lubrication and maintenance

Good lubrication and maintenance to prolong the service life of the grinding machine, maintain the accuracy and reliability of the grinding machine. Lubrication purpose is to reduce the grinding machine of friction surface and transmission vice wear mechanism, and improve the sensitivity of agency work. Such as dynamic pressure bearing grinding machine spindle, the grinding wheel rack oil pool once every three months to replace precision spindle oil, commonly used lube oil for N2 spindle oil, N5 spindle oil two kinds. Requires a high degree of main shaft of the oil film of lubricating oil, so it can't use the wrong oil, some high precision grinding machine spindle dynamic pressure bearing the turbine oil and kerosene configuration. Grinding machine workbench longitudinal guide, grinding wheel frame transverse guide with lubricant oil is a total loss system, such as L - AN46, L - AN32、L- AN68。 Inside the circle abrasive rolling bearing, 500 h to replace a lubricating oil, such as lithium grease 3 and no. 3, calcium base grease. Other all lubricating points with the drops of oil lubrication, such as the tailstock sleeve oiling hole, horizontal to feed the handwheel lubricating oil cup, workbench longitudinal wheel lubrication cup and so on all need to inject oil 2 total loss system. Grinding machine of the maintenance of the bed is often very important to maintain, grinding machine to normal operation, prevent to produce grinding machine grinding machine breakdown or damage to, reduce the precision grinding machine. ( 1) Grinding machine maintenance points (1) the reasonable grinding machine operation, does not harm the grinding machine parts, mechanical structure, (2) the work must be clean before and after grinding machine, check the grinding machine parts, mechanical structure, hydraulic system, cooling system is normal, and promptly eliminate grinding machine fault repair. (3) on the workbench to adjust the head, tail seat, must wipe the junction surface, and the lubricating oil after moving head or the tailstock. Protect the workbench, head and tailstock connection between the grinding precision. (4) manual part should be in accordance with the provisions of lubrication oil filling, and to ensure that the oil level must be high (5) periodically flush the cooling system, the reasonable change of cutting fluid. Treatment of waste cutting fluid should comply with the requirements of environmental protection. High-speed hydraulic bearing temperature rise should be below 60 c (1) the different parameters of the precision grade and the accuracy of the grinding machine and workpiece and feet す corresponding, in order to protect the precision grinding machine. ⑧) Grinding machine open sliding surface and the mechanical units must besmear antirust oil. Pet-name ruby collision or not hair grinding machine parts of working face. Grinding machine operation after 500 h ・ needs a level of service. Level 1 maintenance work is given priority to with operators, maintenance personnel with us. Maintenance of common tools with the slotted screw whorls, phillips screw whorls, live, fruit plate, hand, inner hexagon spanner wrench whole and complete set of wrench, lock wrench ( 2) Level 1 maintenance steps (1) to cut off the power supply, shake a hand wheel to make the grinding carriage return to position, after driving head and tailstock to (2) clean the grinder iron more parts on both ends of the table, such as water tank, liquid chip box, shield shell (3) wash head spindle, the tailstock sleeve with diesel, hydraulic pump, filter, etc. (4) under the guide of overhaul personnel, check the grinding wheel rack and lathe bed oil pool of oil, oil field work, etc. , and according to the actual situation changing or supplements lubricating oil and hydraulic oil.
