Adjusting X-axis & Z-axis Gibs
One of the most important maintenance jobs for mechanical components installed on all Alloy Wheel Repair CNC lathes is to keep both X-axis and Z-axis Gibs clean and lubricated in order to keep them in perfect working conditions. Needless to say, the quality of alloy wheel surface finishes is depending upon the performance from linear motions of both X-axis and Z-axis movement under both automatic mode (using program) and manual mode.
Lehigh MR-2540 Alloy Wheel Repair Diamond Cutting CNC lathe
When a new Alloy wheel repair CNC lathe, such as, Lehigh MR-2540 or Lehigh MR-2940, is delivered, gibs at both the X-axis (cross slide) and Z-axis (saddle) have been adjusted to their best working positions. After 3 to 6 months of operation, however, they could become loose due to vibrations and/or wear and tear depending on working hours. It is very important to check them on a regular basis and make necessary adjustments in order to provide best machining accuracy and working conditions.
At cross feed direction or X-axis, there is only one gib, which is located on the right hand side of the cross slide with full length of the cross slide, which is referring to the long table on which the tool post is mounted on.
