Applications of FGM320 B CNC Gear Form Grinding Machine
The motor of FGM320 B is driven by SIEMENS high performance motorized spindle, which can satisfy the linear speed requirements of small grinding wheel and high speed grinding wheel.
Features of FGM320 B CNC Gear Form Grinding Machine
1. There are 4 servo axes: feed axis X of grinding head; movement axis Z of grinding head, rotary axis A of grinding head and rotary axis C of workhead. Axes X, Z and C are full-closed loop control. Imported linear roller guideways with high precision and rigidity are used for linear axes X and Z. Precision combined bearings are adopted for rotary axis A to guarantee accurate positioning for helix angle of the grinding head and high rigidity. C axis is driven by torque motor, which eliminates the backlash, guarantees the accurate indexing and positioning. The diamond dressing spindle S2 is driven by servo motor.
2. The independently developed profile grinding software can generate the profile file of wheel according to the customer's workpiece to be ground. In addition, the software integrates most of the operation process of the machine, which features friendly interface, visible layer, convenient parameter input and easy operation.
3. The grinding cycle is controlled with CNC system; wheel dressing, compensating and automatic grinding cycle are completed with once programming.
4. A fully enclosed cover, cooling pump with big flow and constant temperature refrigeration device are equipped.
