Part Of The Lathe

Spindle box: Also known as the headstock box, its main task is to transfer the main motor through a series of variable speed mechanism to make the spindle to obtain the necessary positive and negative two different rotational speeds, while the spindle box part of the power of the movement to pass to the box. The spindle in the spindle box is the key part of the lathe. The smoothness of the spindle running on the bearing directly affects the machining quality of the workpiece, and the value of the machine tool will be reduced once the spindle's rotation accuracy is reduced. Feed box: Also known as the Knife box, into the box with the feed movement of the variable speed mechanism, adjust its speed change mechanism, you can get the required feed or pitch, through the light bar or lead the movement to the tool holder for cutting. The screw and the light bar: used to connect the feed box and the sliding Board box, and the movement and power of the feed box to the slide box, so that the slide box to obtain longitudinal linear motion. The screw is specially used for turning all kinds of threads, and when the other surface of the workpiece is turned on, only the Poles are applied, without the screw. Students should combine the contents of the box to distinguish between the light bar and the screw. Crate: Is the lathe into the movement of the control box, equipped with the light bar and screw rotation movement into the tool holder linear motion mechanism, through the light bar drive to realize the longitudinal feed movement, lateral feed movement and rapid movement, through the lead-screw driven tool holder for longitudinal linear movement, in order to turn the thread. Knife: Two-layer skateboard (medium, small skateboard), bed saddle and tool body together. Used to install the vehicle knife and drive the car knife for longitudinal, lateral or oblique movement. Tailstock: It is mounted on the bed guide rail and is moved vertically along this rail to adjust its working position. The tailstock is mainly used to install the top, to support the longer workpiece, but also to install drill bits, reamer and other hole processing. Bed: A large base part of a lathe with a high precision guideway (a gable guideway). Used to support and connect the various parts of the lathe, and to ensure that the parts have accurate relative position at work. Cooling device: Cooling device mainly through the cooling water pump will be pressurized in the water tank after the cutting fluid injection to the cutting area, reduce cutting temperature, wash away chips, lubrication processing surface to improve the tool life and workpiece surface processing quality.
