 What is the main role of the center rack of the three supporting claw is? Center frame three supporting claw itself is set. D role in regulating the spatial location of each claw to determine the bearing surface, then crossed plate or dial indicator to measure, its value will always be zero swing. Machine tool accessories so, then the position of the workpiece clamping correct? Machine tool accessories in this state, in use. b is close to the workpiece face drill, then the center drill necessarily departing from the center of rotation of the workpiece only when the center of rotation of the workpiece aligned with the center of the drill, in order to make the center hole drilling operation, which must be symmetrical cross the center line or the bus is detected and the side of the workpiece bus, rail lathe to make them parallel, so that the workpiece Shandong center frame alignment with the knife brand, coincident with the axis of the workpiece spindle turning centers. Machine parts at high precision surface support most, to prevent wear and tear claw support surface, should be between the center frame and the bearing surface of each claw support mat layer of pure copper sheet or fine emery cloth Tianjin center rack with knife total direct , emery cloth should be attached to the back surface of the workpiece. When the machine parts have a groove or a gap in the surface can be made of brass collar mounted on the outer surface of the workpiece support surface for the center frame. Center frame is often filled with oil at the supporting claws when in use, wear and tear to light supporting claws. Feel free to check the wear condition of supporting claw, should support loose timely adjustments. Center frame and with the knife were used in what circumstances? Machine tools when machining the elongate shaft (aspect ratio L / D> 15), in order to prevent the effect of the radial forces of the workpiece generated by the bending deformation of the center frame, or used as an auxiliary support with the knife, in order to increase the rigidity of the workpiece. But many people do not understand the difference between the center frame and with the knife in? Center frame and with the knife usage and differences are as follows: 1, each cylindrical axis machining slender ladder, generally supported the center rack in the middle of the shaft, the right end of each cylindrical first car, also a U-turn after the car after clamping The other end of the cylindrical. 2, the long axis machining or long-barreled (eg cylinder body) of the end face of the center frame with the knife, as well as holes and threaded ends and other Tianjin wholesale center frame with the knife, can clamp the workpiece chuck left, center frame is supported by the right slightly by the middle or right position. 3, with the knife with knife body can move in the same direction under normal circumstances is a positive turning (refers to chuck normal steering), have for the most desirable car slender shaft; while the center rack position is fixed, a process in general do position adjustment, but rigid support is used to strengthen car parts.
