New lathe components:
The main components are: headstock, exchange gearbox, feed box, slide box, tool holder, tailstock, light bar, screw, bed, foot and cooling device.
Headstock: Also known as the headstock, its main task is to pass the rotary motion from the main motor through a series of shifting mechanisms to get the spindle to get the different speeds of the forward and reverse steering, while the spindle box is partially powered. Transfer the movement to the feed box. The spindle in the headstock is a key part of the lathe. The smoothness of the spindle running on the bearing directly affects the machining quality of the workpiece. Once the rotation accuracy of the spindle is reduced, the use value of the machine tool is reduced.
Feed box: also known as the knife box, the shifting mechanism with feed motion in the feed box, adjust the shifting mechanism to get the required feed or pitch, and pass the motion to the knife through the light bar or screw Rack for cutting.
Screw and light bar: used to connect the feed box and the slide box, and transfer the movement and power of the feed box to the slide box, so that the slide box can obtain longitudinal linear motion. The lead screw is specially designed for turning various threads. When turning other surfaces of the workpiece, only the light bar is used, and no screw is used. Students should combine the contents of the slide box to distinguish the difference between the light bar and the lead screw.
Slide box: It is the control box of the lathe feed movement. It is equipped with the mechanism that turns the rotary motion of the light bar and the lead screw into the linear motion of the tool holder. The longitudinal feed motion and the lateral feed motion of the tool holder are realized by the light bar drive. And fast moving, the tool holder is used to drive the tool holder for vertical linear motion to turn the thread.
Tool holder: There are two layers of skateboards (medium and small skateboards), the saddle and the tool holder body. It is used to install the turning tool and drive the turning tool for longitudinal, lateral or oblique movement. Tailstock: Installed on the bed rail and moved longitudinally along the rail to adjust its working position. The tailstock is mainly used to install the rear tip to support longer workpieces, as well as drills, reapers, etc. for hole machining.
Bed: A large basic component of a lathe with a highly accurate guide rail (mountain rail and flat rail). It is used to support and connect the various components of the lathe and to ensure that the components have an accurate relative position during operation.
Cooling device: The cooling device mainly presses the cutting fluid in the water tank by the cooling water pump and then sprays it into the cutting area, reduces the cutting temperature, washes away the chips, and lubricates the machining surface to improve the tool life and the surface processing quality of the workpiece.
