Lathe in use in the process of lubrication and maintenance methods

The precision of the lathe has close relations with processing quality, to ensure processing quality, make the lathe can run properly and reduce wear and tear, in the daily production to correct lubrication of lathe, well good maintenance of machine tools. A, lathe of normal operation to reduce wear and lubrication to make the lathe all friction parts on a lathe for lubrication. Lubrication part marked by Numbers, in addition to note in figure 1, 4, 5 in the lubrication part, need calcium base grease used in industry (3 Butter) For lubrication, the rest are conducted with 40 # machine oil lubrication. Lathe parts of the lubrication method is as follows: ( 1) The lathe headstock rope after in addition to the main shaft bearing with oil lubrication, the rest are all using gear oil splashing and reciprocating pump for lubrication. Box should have enough lubricating oil, the oil level of the oil level should be of signage. Oil change period in general for 3 months at a time. An oil change, should be put in the clean, and then go. ( 2) Hanging wheel box institutions mainly consisted of gear lubrication oil splashing method. The oil level of high and low can observe oil through the hole. Oil change period is also once every three months. ( 3) Feeding bearing and gear box, except with the gear lubrication oil splashing method also depend on upper part of the feed box storage tank, through the wick lubrication. Therefore, in addition to need to pay attention to the hole in the feed tank oil level height, per shift to feed box upper storage tank refueling a moderate amount of time. ( 4) Dragging plate box has a set of worm and worm wheel mechanism, through the variable speed, the agency is used in the lubricating oil, oil from the hole of the flange plate injection, injection to the bottom of the hole edge. Slide in other institutions, with the upper line of oil in storage tank for lubrication. Usually oil once per shift. ( 5) Dragging plate and the rest part by lubricating oil hole. The tailstock spindle, screw and bearing lubrication by oil hole, screw, light bars and the switch rod bearing on lubricating oil hole 2, 3, 7. Refueling once in each shift. Lubrication hanging wheel in the oil cup 1 and lubrication of the bearing plate in the reverse gear oil cup 4, 5, every 5 days plus 3 calcium base grease industry at a time. ( 6) Lathe bed guide rail surface, drag plate guideway and screw in each class before work and after work, should use 40 machine oil lubrication. Second, the lathe maintenance ( 1) Note: when the clamping and correction workpiece clamping workpiece before should first get rid of impurities such as the sediment on the artifacts, in order to avoid impurity is embedded into the dragging plate sliding surface wear or 'bite bad' guide on the clamping or some correction for large size, shape the heavier weight, complicated shape and the clamping surface minor artifacts, should advance mat on the surface of the workpiece under the lathe bed put a board, or live with press plunger to resist the workpiece at the same time, to prevent the workpiece falls off to hit the bad bed surface. Timing in school, if discover the workpiece position is not correct or skew, avoid by all means is hitting, lest affect precision of lathe spindle. ( 2) Tools and tool may not be on the bed surface, so as to avoid damage to the guide rail. ( 3) When clamping complex artifacts, such as at the end of the faceplate and Angle iron hat clip artifacts, must check whether the clamping fastening, weight is symmetric, When necessary and counter weight) , and clean up the bed surface, take the weight. ( 4) Correction three jaw chuck, can not directly with the iron hammer percussion, soft cushion pad must be block or with a wooden hammer percussion. If the deviation is larger, should be slightly loose flange plate chuck fastening screws, fastening again after correction. ( 5) Along the reversing switch installed in the use of lathe, don't suddenly open, ahead running, so as not to damage parts. ( 6) When high speed cutting, chuck block must be installed insurance, to prevent the chuck while backing off. ( 7) Transformation must stop when the spindle speed, so as not to damage the gears in the head of a bed. ( 8) When sanding artifacts, should use bed cover plate on the surface of the workpiece under the bed or paper cover, and in the sand after carefully wipe the bed surface. ( 9) Per shift out of hours to do a good job in lathe clean to prevent the chip, sand, or impurities into the guide rail working face. ( 10) Before using liquid cooling and lubrication, it is necessary to clear the dirt out of the lathe guide rail and cooling lubricants, after using dry cooling lubricants to guide rail, and add oil for lubrication and maintenance. ( 11) According to the rules in the machine tool all needs the part of the lubricating oil lubrication.
