Operating Procedures for Dual-Head CNC Drilling Machines

Operating Procedures for Dual-Head CNC Drilling Machines：

1. Before operation, thoroughly inspect whether the power supply voltage, oil pump, lubrication system, and oil level are normal. Verify the integrity of pressure systems, cooling systems, oil lines, cutting tools, and workholding fixtures. Perform scheduled maintenance on the machine tool.

2. After powering on and starting the machine tool, execute a mechanical zero return operation. Then conduct a 5-minute trial run. Only after confirming the correctness of mechanical components, cutting tools, fixtures, workpieces, and CNC parameters may normal operation commence.

3. Thoroughly verify that program coding, parameter settings, motion sequencing, tool interference checks, workpiece clamping, and switch protections are entirely error-free to prevent accidents, tool damage, or component failure during cyclic machining. Strictly follow operational procedures for trial cutting and tool setting. After debugging, implement program protection measures.

4. During automatic cycle machining, ensure protective doors are securely closed. When manual operations are required while the spindle is rotating, keep your body and clothing away from rotating and moving parts to prevent entanglement accidents.

5. Spindle or turret tool magazine loading must be performed only when all mechanical movements have stopped. Coordinate carefully with team members to prevent accidents. During manual or automatic tool changes, monitor the positions of the turret, tool magazine, robotic arm, and tools. Keep your body and head clear of rotating tool areas to prevent contact injuries.

6. Secure workpieces firmly during clamping to prevent ejection accidents. After clamping, remove chuck wrenches and other adjustment tools to avoid being flung by the rotating spindle.

7. Machine operators should be capable of handling general alarm faults. In case of severe malfunctions, immediately shut off power, secure the scene, report promptly, and maintain detailed records.

8. After completing work, thoroughly clean the machine tool guideways and worktable, and accurately complete the work log.
