A wood lathe is a power tool that fixes a workpiece on a rotating spindle, and is usually used for machining cylindrical workpieces. General wood lathes are equipped with various special tools, which can complete inner and outer circle processing, drilling, threading, cutting groove, end surface processing, outer circle, drilling center hole, turning hole, reaming hole, turning cone, turning forming surface, knurling, coiled spring and other processing procedures.
The lathe is driven by an electric motor, and the spindle is rotated through a belt and gear transmission system to drive the workpiece on the spindle chuck to rotate. Then, the lathe is fixed on the tool holder for turning. The main workpiece is a round rod. The work includes turning end face, inner and outer diameter, arc, taper, drilling, boring, eccentricity, embossing, cutting, grooving, and threading.
Due to the development of the industry, the actual work requirements are increasing day by day. In order to adapt to the trend of various processed products and modern automated processing to meet the needs of production, a variety of different functions and characteristics are developed:
1. Centre Wood Lathe.
Centre lathes are the most widely used types of lathes. In the early days, the transmission of ordinary lathes was driven by a belt-transmitted tower wheel. Today, gear transmissions have been used. The advantage of the gear transmission is that it can accurately grasp the speed of the main shaft, and there is no situation where the speed of the main shaft is too high, the friction of the belt is consumed and slips. Because the main shaft is placed horizontally, it is also called a horizontal lathe. If the bed surface is notched, it is a notched lathe machine.
2. Bench Wood Lathe.
Bench lathe machines are also called tabletop lathe machines. Their type and structure are similar to centre wood lathes. They are usually installed on work tables and named after them. They are suitable for the production of precision measuring tools, instruments and small parts.
3. Vertical Wood Lathe.
The main axis of the vertical lathe is installed vertically, the bed is horizontal, and the workpiece is placed on the rotatable bed. Especially suitable for processing workpieces with large diameter but short length.
4. Turret Wood Lathe.
Hexagon lathe, also known as turret lathe, is designed to replace the tailstock of ordinary lathe with a hexagonal rotating turret. Especially suitable for processing a large number of workpieces in various processing procedures (such as drilling, reaming, boring), suitable for mass production.
5. Automatic Wood Lathe.
The automatic lathe can automatically turn according to the processing order of the work. After turning, it will automatically retract the tool, feed, and turn the next finished product. It is suitable for mass production of small diameter workpieces.
6. Copying Wood Lathe.
Copying lathes, also known as imitation turning lathes, use the stylus to move according to the shape of the model or template, and the turning tool also moves the turning work, so the same workpiece as the model can be turned correctly.
7. CNC Wood Lathe.
The full name is "computer numerical controlled wood lathe", referred to as "CNC machine tool". The advantage is that it is suitable for processing large quantities of workpieces with complex designs and high precision requirements.
