● the pentahedral machining center adopts the overall structural design, which is composed of a horizontal machining center and a vertical machining center; They use a set of work plane system together, and are equipped with a rotary indexing device, which can rotate at any angle to realize multi-facet, turning and milling composite machining. ● the function of the machine tool is highly automated. It is equipped with double spindle and hydraulic rotary gear to realize five axis control. Five side processing can be completed in one clamping, reducing the error of multiple clamping and improving the accuracy. The structural design of vertical and horizontal double bt40/bt50 spindles meets the precision cutting of high hardness materials. The vertical and horizontal spindle can use direct transmission mode to achieve direct torque output. ● the pentahedral machining center meets the complex processing of large parts, breaking the traditional processing mode, improving processing efficiency, spatial accuracy and product quality. It has the characteristics of high rigidity, high power, high torque and heavy cutting in similar equipment, and can give full play to the high-precision machining performance. It can directly cut, skew weave and arc interpolation cutting, and complete milling, boring, drilling, expanding, reaming, tapping and other processing procedures. ● the system is simplified and energy-saving, cost saving, energy consumption saving, manpower saving and floor area saving. ● strong and delicate fuselage structure, high rigidity, high speed and high precision. ● the turntable has clearance elimination function to increase rigidity. ● a set of system controls two units, and the CNC system with special treatment can switch between vertical and horizontal to efficiently complete the precision machining of pentahedral parts.
