What are the components of CNC lathe parts?

u200bNumerical control lathe is the abbreviation of digital program control lathe. It combines the characteristics of universal lathe, precision lathe with high machining accuracy and special lathe with high machining efficiency. It is the most widely used and most widely used type of CNC in China. Lathe pieces. The headstock (headstock) is fixed on the upper left part of the bed. It transmits the rotational movement of the motor to the main shaft and drives the workpiece to rotate together through the fixture. Changing the position of the handle outside the box can make the spindle get multiple rotation speeds with different forward and reverse rotations. Feed box (big tool box) The feed box is fixed on the left front and lower side of the bed, and the rotary motion of the main shaft is transmitted to the lead screw or the smooth rod through the change wheel. Changing the position of the handle outside the box can change the speed of the lead screw or the smooth rod, so as to achieve the purpose of changing the pitch or feed. The slide box (pallet box) is fixed on the front side of the bed saddle and reciprocates longitudinally on the bed guide rail together with the bed saddle. Through it, the rotary motion of the lead screw or the smooth rod is changed into the feed motion of the saddle and the middle slide. Changing the position of the handle outside the box can control the longitudinal or lateral movement (movement direction, start or stop) of the turning tool. Hanging round frame The hanging round frame is installed on the left side of the bed. It is equipped with an exchange gear (hanging wheel), which transmits the rotation of the main shaft to the feed box. Adjust the gear on the hanging wheel frame and cooperate with the feed box to turn threads with different pitches. The tool holder is fixed on the small drag plate, and is used to install the spare turning tool. The carriage carriage includes 4 parts: the saddle, the middle slide, the turntable and the small slide. The bed saddle is installed on the rails outside the bed and can move longitudinally along the bed rails; the middle slide can move horizontally along the dovetail rail on the upper part of the bed saddle; the small slide can move longitudinally along the dovetail rail on the upper part of the turntable. After the turntable rotates an angle, the small sliding plate can drive the knife to move diagonally, which is used to turn the shorter inner and outer conical surfaces. Tailstock The tailstock is installed on the guide rails in the bed and can move longitudinally along the guide rails of the bed. In the sleeve taper hole on the tailstock, knives and auxiliary tools such as center, drill, reamer, and tap can be installed for supporting workpieces, drilling, reaming, tapping, etc. The bed is the basic support of the lathe. It is fixed on the left and right bed legs to support the main parts of the lathe and keep them in a difficult relative position when working. Two sets of guide rails on the bed provide accurate guidance for the longitudinal movement of the saddle and tailstock. Lead screw The lead screw is mainly used for turning threads and is one of the main precision parts on the lathe. In order to maintain the accuracy of the lead screw for a long time, the lead screw is generally not used for automatic feeding. The light bar transmits the movement of the feed box to the slide box, so that the saddle and the middle slide plate can be fed vertically and horizontally. Joystick Joystick is one of the main parts of the lathe control mechanism. At the left end of the joystick and the right side of the slide box, a joystick is installed. The operator can easily manipulate the handle to control the forward, reverse or stop of the lathe spindle.
