In order to make the CNC drilling machine operate continuously and reliably for a long time, in addition to ensuring the quality elements of the planer, it is also closely related to proper maintenance, immediate fault removal and immediate maintenance. In the application, from the perspective of improving the characteristics of CNC drilling machines, maintenance should have two practical meanings: on the one hand, daily maintenance, the key is to better expand the MTBF of the planer, and on the other hand, fault maintenance. The purpose of this is to reduce the mean time to overhaul (MTTR), both of which are fundamental guarantees of optimal equipment performance. So how to prevent the failure of CNC drilling machine?
1. Failure of CNC drilling machine spindle bearing components
Common failures include equipment failures, automatic tightening of drilling tools, automatic motor equipment failures, and unstable spindle bearing travel precision for maintenance.
2. The drive gear of the CNC drilling machine is faulty
Generally, when the quality of fitness exercise is reduced, it will display information failure, such as the reduction of precision level, the expansion of the gap, the crawling of the operating table during the fitness exercise, and the excessive noise of the rolling bearing. Generally, such faults are cleared according to the adjustment of the preload of the motion pair, the adjustment of the loose chain segment and the adjustment of the compensation of the chain segment.
3. The automatic tool changer (ATC) of the CNC drilling machine fails
The incorrectness of the equipment is about 50%, which occurs in: CNC tool offset failure, large inaccurate positioning, equipment is clamped, and the tool table is unstable and incorrect. The fitness exercise of the intelligent robot is very large, causing the tool changer to be stuck and all the equipment to stop working.
4. The limit switch used for inspection of CNC drilling machine parts is faulty
The key factors that endanger the normal pressing of the limit switch are the change of the offset of the subject movable component, the reliability of the mechanical equipment that presses the limit switch, and the quality characteristics of the limit switch itself. Adjust or replace parts
5. Failure of CNC drilling machine spare parts
Accessories include cutting oil, cutting removal equipment, slide rail maintenance, spindle bearing cooling temperature control box and other shortcomings.
