Daily Maintenance Routine
Proper daily maintenance is the foundation of reliable drilling machine operation. Before each shift, operators should wipe down all external surfaces, paying special attention to the base slideway, spindle housing, and column surfaces. Lubrication points must be checked and replenished with the correct grade of oil to prevent premature wear on moving parts.
Troubleshooting Position Deviation
Drilling position deviation is one of the most common issues in CNC drilling operations. This problem typically stems from calibration drift, worn tool holders, or backlash in the feed mechanism. Operators should verify workpiece fixturing rigidity, inspect tool wear patterns, and confirm G-code coordinates before running production batches to minimize deviation errors.
Electrical System Inspection
The electrical control cabinet should be inspected weekly for loose connections, overheated components, and dust accumulation. Motor brushes on older machines require periodic replacement, and variable frequency drives should be checked for error codes. Maintaining stable voltage supply protects sensitive CNC controllers from damage.
Coolant and Chip Management
Coolant levels and concentration must be monitored daily to ensure effective heat dissipation during drilling operations. Chip accumulation around the worktable and ways should be cleared after every job to prevent contamination of lubrication systems. Using the correct coolant type for your workpiece material extends both tool life and machine accuracy.
