Applications of WGM320 CNC Worm Wheel Gear Grinding Machine
WGM320 CNC Worm Wheel Gear Grinding Machine is a high efficiency and precision machine with good universality, which is used to grind standard or modified involute gears. WGM320 is suitable for precision grinding of gears with medium module hardened gear in batch production in the industries of aircraft, automobile, machine tool, motor bicycle, textile machinery, gearbox and all kinds of transmissions devices.
Features of WGM320 CNC Worm Wheel Gear Grinding Machine
1. The phase locking servo system is used to control the dividing driving and differential driving instead of gear transmission, which improves the working accuracy and reduces the waves on the ground tool flacks.
2. CNC feed system used for variable radial feed of grinding wheel improves the machine efficiency greatly.
3. The proportional valve and grating are used to control the movement of slide. Different speeds can be set for each travel. The evenness of grinding allowance on both flanks of each tooth can be displayed and made even with a correction button.
4. Diamond roller is used for wheel dressing.
5. Lead modification function can be used for grinding crowned gears, and the diamond roller is used for grinding gears with profile modification. Manual and automatic grinding cycles are available. During automatic grinding cycle, the clamping and unclamping of workpiece can be achieved time after time, the tangential shift of workpiece along grinding wheel, grinding accuracy and uniformity of workpiece in one batch is guaranteed.
6. Workpiece parameter and processing parameter can be input via touch keyboard and displayed on the touch screen. In addition, all kinds of processing parameters can be stored in the computer.
