YK7332A Gear Profile Form Grinding Machine

YK7332A Gear Profile Form Grinding Machine is designed for grinding precision gears which less than diameter of 320 mm and special gear for industries of automotive, aviation, transmission and machine tool in batches. And it is especially suitable for grinding high-speed gears and multiple gears with special profile modification or special fillet at tips and roots. Besides, it can also be used for grinding non-involute components like cycloidal gear, rotors of oil pumps, precision splines, and screw, etc. FEATURES:NUM 1050 CNC system is chosen for this machine. There are altogether 4 axes for this machine: axis X for feed of grinding head; axis Z for movement of grinding head, rotary axis A of grinding head and indexing axis C. Among them, axes X, Z and C are all controlled with semi-closed loop. Imported linear roller guide ways with high precision and rigidity are used for the guide ways of the linear axes X and Z. And precision combined bearings of INA are chosen for the rotary axis of the wheel so as to guarantee the accurate positioning for the helix angle of the grinding head and the high rigidity. A dual worm backlash relieving mechanism is exploited for the indexing axis C to reach the requirement of indexing and positioning accuracy.And for the motor of the grinding head, a spindle motor with the speed up to 18,000 rpm is used, which meet the needs for small wheel with high periphery speed.This machine is designed for using ordinary wheels. Based on the data file created with the form dressing software according to the requirement for profile modification and the fillet curves at the tip and root, the dressing of the wheel is carried out with a diamond roller through the compensation of axes X and Z. The grinding cycle is controlled with the CNC control; and the wheel dressing, compensating, and automatic grinding cycle are finished with one programming. The grinding parameters and allowances are displayed automatically. And this machine is characterized as easy operation and high grinding accuracy. A fully enclosed cover is designed for this machine. An air conditioning device and a gear cooled pump with larger quantity are also equipped. A static exhaustion device ensures the clean working environment.
