Specific steps for safe operation of CNC woodworking lathe

How to safely operate the CNC woodworking lathe during operation, and what are the specific safe operation steps. Let me give you a detailed introduction.

1. Before operating the CNC woodworking lathe, the workpiece should be installed firmly, the tailstock fixing nut should be tightened, the thimble should be locked with the locking device, the workpiece should be rotated by hand, and the position of the tool post should be adjusted and fixed. The tool post should be at the center of the workpiece 2~3mm, if the distance between the tool holder and the workpiece is too large, it is easy to pierce the knife and cause safety accidents;

　　2. After the wood is clamped, you must turn the chuck by hand to calibrate, and check whether the tool bar and the top screw of the tool rest are firm, and then turn on the power to test drive;

　　3. For long materials over 100mm, the tailstock top must be used to hold it firmly during processing;

4. When installing a tool on a CNC woodworking lathe, the length of the tool bar extending from the tool holder should be shorter than 50mm, and the tool bar should maintain a length of 150mm. When processing large workpieces (above 500mm in diameter), the tool must be fixed on the tool holder. The knife should be clamped firmly, and the knife should not be inserted too hard;

5. The amount of cutting tools should be appropriate. The amount of cutting tools should be smaller due to the edges and corners of the workpiece during rough turning. After turning the corners and turning the basic round, the speed can be increased. Use flat turning tools for fine turning, and the amount of cutting tools should not exceed 0.8mm /turn;

　　6. Keep the cutting edge of the turning tool sharp and use a dull tool to turn the workpiece, which affects the quality and is prone to accidents;

　　7. Small workpieces with knots are not allowed to be cut. When the workpiece is with knots, do not drive fast. If there are other hard things in the wood, it must be removed in time, otherwise processing is not allowed;

　　 8. When turning irregular wood with edges and corners on a CNC woodworking lathe, you should first use a fixed turning tool to cut the edges and corners, and then use the lathe for fine processing;

　　9. Polishing the surface of the well-turned parts with sandpaper can improve the surface smoothness. The hand pressure should not be too large. The sandpaper should move along the surface of the workpiece at a uniform speed to realize the grinding of the workpiece without causing excessive local wear of the workpiece;

　　10. When turning the first tool on a CNC woodworking lathe, the feed should be small. When polishing with emery cloth or sandpaper, the right hand should be in front and the left hand should be behind, and the force should be even;

　　11. When turning glue-bonded wood, it must be placed for 24 hours before processing on a lathe;

　　12. The rotation speed of the CNC woodworking lathe is determined by the shape and material of the workpiece, and it should not be too fast to prevent it from flying out and hurting people;

13. Choose the spindle speed, and turn large workpieces. The speed should be slower. Because large workpieces have greater inertia when turning, fast turning is prone to accidents. When turning small workpieces, the speed can be appropriately faster, and the turning speed is fast and easy. To obtain a smooth and clean workpiece, it is particularly important to note that before turning the rough workpiece, the edge of the wood needs to be basically cut into a circle, and the square material must not be turned straight, otherwise, it is easy to cause accidents;

　　14. Strictly abide by the safety operating regulations of CNC woodworking lathes. Before starting the lathe, check whether all parts are normal before operation.
