YK7332ANC forming grinding wheel gear grinding machine
YK7332A CNC forming gear grinding machine isφ The gear grinding equipment with high precision, large batch and special gear grinding below 320mm can be applied to the machining of national key projects and industrial gears such as automobile and machine tool, especially the machining of high-speed gear and multi-split gear with gear profile modification requirements and special requirements for the transition part of tooth root and tooth top. In addition, it can grind the non-involute gear profiles such as cycloid gear, oil pump rotor, high-precision spline and screw.
The machine tool adopts NUM1050 numerical control system, and the whole machine has four servo shafts: feed shaft X of grinding wheel rack, feed shaft Z of grinding wheel rack, and the rotation of grinding wheel rack is fully closed-loop control. Imported high-precision and rigid roller linear guide rails are selected for linear axis X and Z guide rails. The rotating shaft A of the grinding wheel frame adopts INA high-precision composite bearing to meet the accurate positioning and high rigidity requirements of the spiral angle of the grinding wheel frame. The dividing shaft C adopts a double-worm clearance elimination mechanism to ensure the accurate requirements of dividing and positioning. Electrospindle is selected as the grinding machine motor, with the maximum speed up to 24000rpm, which can meet the linear speed requirements of small grinding machine grinding wheel and high-speed grinding wheel.
Ordinary grinding wheel is selected for machine tool grinding. The forming and finishing software is used to generate NC system data files according to the user's requirements for grinding workpiece. Use the interpolation motion of the working axis X and Y of the machine tool, and use the diamond roller to complete the sectional forming and finishing of the grinding wheel. The grinding cycle of the machine tool is controlled by the numerical control system, and the grinding wheel finishing, compensation and workpiece grinding automatic cycle control are completed through one programming.
The machine tool housing is fully enclosed. The workpiece is cooled by the large-flow cooling pump and equipped with the thermostatic refrigeration equipment. The whole machine is equipped with electrostatic mist absorption device, and the working environment is clean and sanitary.
