Mainspindle : also known as the headstock, its main task ing from the main motor rotation speed through a series of institutionsrequired for the spindle box allocate part of the power the campaign to passinto the box. Lathe headstock spindle is the key to the middle part. Spindlebearing on the smooth operation of the workpiece directly affect theprocessing quality, once the accuracy of the rotation decreased, themachine’s using values. Feed box: also known as the cutting box, feed tank equipped with avanable speed feed motion in the body, it can adjust the speed to changemechanism, obtain the required feed rate or screw pitch, the motion anddriving force to slide crate to make crate to get the vertical linear slidemotion. Start lathe check each variable speed are in the lathe meutral. Clutchwhether is in the correct position, joystick is no in stop state, whenconfirmed, close the lathe total switch power supply. Saddle bed accordingto the green button, motor started brought up to slip board box on the rightside of the lever handle, spindle is turned; Lever handle back into the middleposition, spindle stop turn move; Lever handle press, sp
