Tools, parts and other objects shall not be stacked on the workbench. Pay attention to the distance between the tool and the workpiece to prevent collision accidents.

5. Before installing the milling cutter, check whether the cutter is matched and intact. The milling cutter shall be installed as close to the spindle as possible. After installation, it shall be tested. The workpiece shall be installed firmly.

6. When working, feed by hand first, and then walk the knife automatically step by step. When running the automatic tool feeding, open the hand wheel, pay attention to whether the limit stop is firm, do not put it on the head, and do not go to the two extremes and break the lead screw; When using the fast travel, check whether there will be collision in advance to avoid damaging the machine parts and flying out of the milling cutter to hurt people. Always check whether the safety spring in the handle is effective and reliable.

7. It is forbidden to touch the cutting edge and machining parts by hand during cutting. The workpiece must be stopped for measurement and inspection, and the workpiece shall not be adjusted during cutting.

8. The feed must be stopped before the spindle stops. If the cutting depth is large, the tool shall be stopped first, the power supply shall be cut off when changing the wheel, the change wheel clearance shall be appropriate, and the back nut of the change wheel frame shall be fastened to avoid falling off; The rotating speed should not be too fast when processing the blank, and the tool amount and feed rate should be selected.

9. In case of any fault of the machine tool, stop the machine immediately for inspection and report to the construction and support department to send a mechanic for repair. Clean up after work and turn off the power supply.

Machine tool accessories mainly include: end milling head, dividing head, disc table, universal angle worktable and Bench Vise, so it has strong versatility and wide application.
