How to prevent tool jamming in a gantry machining center?

The key to preventing tool jamming in a gantry machining center lies in regular maintenance and standardized operation. The following are the specific measures

Ⅰ. Regular maintenance and inspection

Spindle orientation Angle calibration ‌

Every month, use a 3-point combined mold tool setter to correct the orientation positions of the spindle and the tool changing manipulator, ensuring that the tool changing point of the manipulator is aligned with the center point of the spindle.

Check whether the synchronous toothed belt of the main shaft is loose and replace the worn parts in time.

Tool change origin reset ‌

Check the tool change origin position every quarter to avoid offset caused by collision or misoperation.

Record the Z-axis coordinate values and write them into parameter No.1241 (FANUC system).

Tool cylinder maintenance ‌

Regularly check the pressure of the pneumatic/hydraulic system to ensure that the stroke of the knife cutting cylinder is normal.

Replace the elastic gasket in the tool cutting cylinder to prevent the tool from getting stuck due to stroke offset.

Ⅱ. Operating Norms

Avoid misoperation ‌

Strictly follow the tool changing process and avoid forcibly changing the tool when the spindle has not completely stopped.

Regularly train the operators to enhance their ability to identify abnormal tool changes.

Parameter Settings check ‌

Regularly check the tool change instructions in the CNC program (such as M19) to ensure that the parameter Settings are correct.

Check whether the sensor signal is normal to avoid random knives caused by abnormal signals.

Ⅲ. Environment and Maintenance

Keep clean ‌

Regularly clean the tool magazine and the manipulator to prevent chip accumulation from affecting the tool changing action.

Check the lubrication system to ensure that the moving parts of the mechanical hand are adequately lubricated.

Monitor system status ‌

Regularly check the alarm records of the CNC system and promptly handle potential faults.

Record the number of abnormal tool changes, analyze the causes of high-frequency faults and make targeted improvements.

Through the above measures, the risk of tool jamming can be significantly reduced, ensuring the stable operation of the equipment.
