Woodworking lathe is a kind of woodworking machinery. It consists of a bed, a tailstock installed at the end of the guide rail of the bed, a tool holder installed in the middle of the guide rail of the bed, a headstock installed at the head of the bed, and a headstock installed at the head of the bed. The main shaft on the box and the chuck on it, the motor installed on the headstock, the motor shaft, the main shaft and the variable speed transmission on the headstock are composed of parts, which are used to make round wooden pieces. Woodworking lathes use turning tools to process wood, mainly including ordinary woodworking lathes, copy woodworking lathes and round bar machines.

How to use woodworking lathe

There are two main working methods of woodworking lathes: shaft turning method and disc turning method. Use flat turning tools, oblique turning tools, diamond turning tools, semi-circular turning tools, partition turning tools, etc. to process wood, so how do woodworking lathes work? What to use?

• Select wood, preferably square angle wood, wood with cracks and pine knots can not be used, the wood used should remove the metal objects and sand attached to the wood.
• Center the wood, saw the cross groove, and put the front end of the movable top center into the groove.
• Insert the movable top center into the main shaft hole of the front seat of the lathe, move the tailstock to an appropriate position, fix it on the bed, and then rotate the tailstock handwheel to make the fixed top center on the tailstock tightly push into the wood center hole .
• Rotate the wood by hand for a few counts, then reverse the tailstock handwheel for one turn, slightly withdraw from the fixed top center, add lubricating oil into the center hole of the wood, and rotate the handwheel clockwise to make the top center re-enter the center hole Inside.
• Move the turning tool holder to an appropriate position and fix it on the bed. Adjust the height of the turning tool holder so that the distance between the tool holder surface and the outer edge of the wood is about 3mm.
• Try turning the wood by hand to observe whether the position of the tool holder is appropriate and whether the wood can rotate smoothly. If any abnormality is found, readjust it immediately.
• Start the machine to run at a low speed, and observe that the operation is stable before feeding.
• First use a semi-circular turning tool for rough turning, hold the turning tool in one hand, stabilize the position of the turning tool, and guide the direction, hold the turning tool handle with the other hand, control the amount of feed, and turn from the center of the wood to both ends until the wood is complete. until the wood is round; after the wood is turned into a round shaft, switch to a higher speed turning.
• Stop the machine, adjust the position of the turning tool again, and use a pen to draw the position to be further turned on the wood.
• According to the needs, use suitable turning tools for forming turning. Generally, circular turning tools or semi-circular turning tools are used for turning inner concave arcs. For square grooves, separate turning tools or flat turning tools should be used, and V-shaped grooves and convex arcs are used for turning. Diamond-shaped turning tools or oblique cutting tools, and flat turning tools and oblique cutting tools are used for turning straight lines.
• After turning and forming, remove the tool holder and smooth it with sandpaper.

What are the precautions for the use of woodworking lathes

• Before use, carefully check the various parts of the lathe as well as the tools and fixtures to see if they are flexible and reliable; the workpiece should be clamped and thumped with a thimble, and turned for trial operation by hand.
• During operation, the appropriate amount of feed material should be selected and the speed should be adjusted according to the hardness of the workpiece wood.
• During the turning process, the smoothness of the workpiece cannot be checked by hand to avoid accidents; when sandpaper is needed for grinding, the tool holder must be removed first, and the woodworking lathe cannot be braked by hand when it is rotated.
• When processing square wood, it must be processed into a cylinder before it can be processed on a lathe. Wood with knots or cracks cannot be processed by a wood lathe.
