Lathe is a machine tool that mainly lathes rotating workpieces with turning tools. In the lathe can also be used bit, reamer, reamer, tap, dice and knurled tools for the corresponding processing.
Head stock: also known as the headstock box, its main task is to rotate the main motor came from a series of speed transmission mechanism through the body so that the spindle to obtain the desired positive and negative two different speeds of rotation, at the same time split the headstock power Pass the motion to the feed box. The spindle in the spindle box is the key part of the lathe. The stability of the spindle running on the bearing directly affects the processing quality of the workpiece. Once the rotation precision of the spindle is reduced, the use value of the machine tool will be reduced. Feed box: also known as the feed box, feeding box equipped with feed movement of the speed change mechanism, adjust its speed change mechanism, can be the desired feed rate or pitch, the light or screw movement to the knife Rack for cutting. Screw and light bar: used to connect the feed box and the skateboard box, and the feed box movement and power to the skateboard box, the skateboard box to obtain longitudinal linear motion. Screw is designed for turning a variety of threads and set the workpiece in the other surface turning, only the light bar, no lead screw. Students should combine the contents of the slide box to distinguish the difference between light and lead screw. Sliding box: a lathe feed motion control box, built-in light bar and screw rotation into a linear motion of the knife body, through the light bar to achieve vertical feed tool movement, horizontal feed movement And fast moving, driven by the screwdriver vertical longitudinal movement, so that turning thread. Turret: There are two skateboards (medium and small skateboards), saddle and turret body together. Used to install the turning tool and drive the turning tool to make longitudinal, horizontal or oblique movement. Tailstock: mounted on the bed rails, and along the rail longitudinal movement to adjust its working position. Tailstock is mainly used to install the top post to support longer workpieces, but also to install drill bits, reamers, etc. for hole processing. Bed: A large base part of a lathe with high-precision guide rails (Yamato rails and flat rails). Used to support and connect the various components of the lathe, and to ensure that each part has an accurate relative position at work. Cooling device: Cooling device mainly through the cooling water pump in the tank after the cutting fluid pressure sprayed into the cutting area, reducing the cutting temperature, washed away the chip, lubricating the machined surface to improve tool life and workpiece surface quality.
