When turning workpiece clamping

Lathe processing more than for shaft parts and disc set of parts, sometimes in irregular parts aspirant line round, end of the inner hole or processing. So the parts have different clamping method on a lathe. Three jaw self centering chuck clamping this is one of the most often on lathe clamping method, sets of disc type of artifacts and hexagon section applies this method the clamping workpiece, and the rapid clamping, but centering precision is not high, generally is 0. 05 ~ 0. 15mm。 Four jaw chuck and his four jaw chuck clamping four claws respectively by turning the screw on the single action and implementation. It can be used to square, oval, or irregular shape workpiece clamping, using the line according to processing requirements to align the artifacts to adjust to the desired location. This law to adjust the time consuming work, but the clamping force is big. Clamping faceplate is using screw, clamp, Angle iron, etc. The workpiece clamping on the desired location, it applies to irregular workpiece. Top clamping available in order to reduce the workpiece deformation and vibration double top clamping workpiece. Commonly used to rest or rest for auxiliary support, to increase the rigidity of workpiece. Follow rest moves with tool post for cylindrical axis processing. When machining slender ladder shaft, use the center frame. Center frame fixed on the bed, not with the move tool carrier. Filled with heart shaft axis is mainly used for clamping with panel, set of parts. To ensure the hole and cylindrical alignment and face and verticality of hole. Length to diameter ratio hours, when the workpiece spindle nut pressure should be adopted. When the workpiece length is greater than the pore size, can be used with taper ( The latter to 1:50 00) Passed by with the friction of the spindle, movement, and method of cutting parameter can't be too big.
