What are the precautions for woodworking lathe operation?

Woodworking lathe is a machine for machining circular workpieces. Door handles, gyroscopes, tables, chairs and legs are all made of woodworking lathes. The use method of woodworking lathe is to turn wood by tools. The specific use method is to select the appropriate wood, put it into the woodworking lathe, then adjust the position and distance of the tool rest, select the appropriate tool according to the wood of the workpiece, rough cut first, then turn at high speed, and then polish it with sandpaper. When using woodworking lathe, we should also pay attention to the selection of wood and the adjustment of tool speed. Let's take a look at the usage and precautions of woodworking lathe. 1. What is a woodworking lathe?

Woodworking lathe is a kind of woodworking machinery, which consists of lathe bed, tailstock installed at the tail of lathe bed guide rail, tool rest installed in the middle of lathe bed guide rail, headstock installed at the head of lathe bed, spindle installed on headstock and its chuck, motor installed on headstock, variable speed transmission device installed on motor shaft, spindle and headstock, etc. It is used to make round wooden objects. Woodworking lathes use turning tools to process wood, mainly including ordinary woodworking lathes, copying woodworking lathes and round bar machines.

Second, the use of woodworking lathe

There are two main working modes of woodworking lathe: round shaft turning and disc turning. Use flat turning tools, oblique turning tools, diamond turning tools, semi-circular turning tools and separation turning tools to process wood. How to use the woodworking lathe?

1, choose wood, square angle wood is appropriate, wood with cracks and loose joints can not be used, and the wood used should remove the metal and sand attached to the wood.

2. Center the wood, saw out a cross groove, and put the front end of the movable center into the groove.

3. Insert the movable center into the spindle hole of the lathe front seat, move the tailstock to a proper position and fix it on the lathe bed, and then turn the tailstock handwheel to push the fixed center on the tailstock tightly into the wooden center hole.

4. Turn the wood by hand and count it, then reverse the tailstock handwheel once, slightly withdraw from the fixed jacking shaft, add lubricating oil into the central hole of the wood, and turn the handwheel clockwise to make the jacking shaft re-enter the central hole.

5. Move the lathe tool rest to a suitable position and fix it on the lathe bed. Adjust the height of lathe tool rest so that the distance between the tool rest surface and the outer edge of wood is about 3mm. ..

6. Try to turn the wood by hand, and observe whether the position of the tool rest is appropriate and whether the wood can rotate smoothly. If any abnormality is found, readjust immediately.

7. Start the machine at low speed, and observe that the operation is really smooth before feeding.

8, rough turning with a semicircle turning tool. Before holding the turning tool in one hand, stabilize the position of the turning tool and guide the direction, while holding the turning tool handle in the other hand to control the feed, and turn from the center of the wood to both ends until the wood is round; After the wood becomes a round shaft, the rotation speed is higher.

9. Stop the machine, adjust the position of the turning tool again, and draw the position of further rotation on the wood with a pen.

10, according to the need, use the appropriate turning tool for forming and turning. Generally, circular turning tools or semi-circular turning tools are used for turning concave arcs, separating turning tools or flat turning tools are suitable for turning square grooves, diamond turning tools or inclined turning tools are used for turning V-shaped grooves and convex arcs, and flat turning tools and inclined turning tools are used for turning straight lines.

1 1. After turning, remove the tool rest and polish it with sandpaper.

Third, what are the precautions for the use and operation of woodworking lathes?

1, before use, carefully check whether the various parts of the lathe devices, tools and fixtures are flexible and reliable; The workpiece should be clamped and jacked by thimble, and turned by hand for trial operation. Don't start work directly, and don't start work until you are sure that the situation is good.

2, operation, should according to the hardness of the workpiece wood, choose the appropriate feed, adjust the speed.

3, in the process of turning, can't touch to check the smoothness of the workpiece, so as to avoid accidents; When sandpaper grinding is needed, the tool rest should be removed first. When the woodworking lathe rotates, it cannot be braked by hand.

4. When the square wood is processed, it must be processed into a cylinder before it can be processed on the lathe. Wood with knots or cracks cannot be processed by a woodworking lathe.
