Rotary's top machine tool is mainly used lathe shaft parts, with the center hole location, so that the workpiece to obtain a high dimensional accuracy, because the use of more frequent, machining tool to scratch the top, 60 ° cone tip fracture, surface wear affect the use or even scrapped, would have inflicted economic losses. However, machine tool accessories, as long as the bearing inside the top is not bad, you can be on the 60 ° cone cylindrical grinding machine grinding is good, so that rotary top continue normal use. Clamping using conventional methods, because the processing base with the top job reference do not coincide, processing out of the top precision is relatively low, after several tests are summarized Zaozhuang machine tool accessories, the top fixture, rotary top rotationally Weifang machine tool accessories, auxiliary devices, etc. certain aspects of the measures taken, the processing of qualified products. Collet is part of the tool holder is mounted on a drilling / milling machine tool accessories drill chuck Weihai, its function is to clamp drill knife or cutter. Collet materials used for: 65Mn. ER collet series can be divided, ST straight shank \ C type \ Powerful, OZ Collet Series, SK series \ SD series collet, collet safety wire tapping torque. ER collet is one collet, ER collet, also known as high-precision collet, collet precision. Its stable performance, high precision, handling is simple, cheap and therefore use more. Its characteristic is radial runout is only half of C-type collet, greatly improve product during processing accuracy requirements, thereby reducing scrap rate.
