AI Technical Summary
Technical Problem
After prolonged use or abnormal operation, the inner taper hole of the tool holder of a five-axis grinding machine is damaged, resulting in reduced installation accuracy, long maintenance cycle, high cost, and impact on production progress.
Method used
The five-axis grinding machine uses a self-repairing method, employing grinding wheels and dressing tools to fine or rough grind the inner tapered hole. It relies on the machine's own positioning accuracy for self-repair, shortening the maintenance cycle and reducing costs.
Benefits of technology
It achieves self-repair without disassembling and replacing the tool holder, shortening maintenance time, reducing maintenance costs, minimizing equipment downtime, and improving production efficiency.

Abstract
This invention discloses a self-repairing method for the tool holder of a five-axis grinding machine, relating to the field of grinding machine technology. The method includes: Step 1, confirming the repair plan and measuring the radial runout value of the inner tapered hole of the tool holder on the first axis; Step 2, installing a grinding wheel on the second axis and a dressing tool on the first axis; Step 3, adjusting the relative position between the central axes of the first and second axes so that the dressing tool contacts the outer peripheral wall of the grinding wheel, then rotating the second axis and moving along its rotation axis to dress the radial outer peripheral wall of the grinding wheel using the dressing tool; Step 4, removing the dressing tool so that the outer peripheral wall of the grinding wheel contacts the inner peripheral wall of the inner tapered hole, rotating the first and second axes to dress the inner peripheral wall of the inner tapered hole using the grinding wheel. This self-repairing process relies on the self-positioning accuracy of the five-axis grinding machine, eliminating the need for parts replacement or return to the factory for inspection and repair. This shortens the tool holder maintenance cycle, reduces maintenance costs, and minimizes the adverse impact of equipment failure on production schedules.
