Applications of FGM320 A CNC Gear Form Grinding Machine
FGM320 A CNC Gear Form Grinding Machine is designed for grinding precision gears with diameter less than 320mm and special gears for industries of automotive, aviation and machine tool in batches. It is especially suitable for grinding high speed gears and multiple gears with special profile modification or transition part of crest and roots. Besides, it can grind non-involute profile like cycloidal gear, oil pump rotor, precision spline and screw.
Features of FGM320 A CNC Gear Form Grinding Machine
1. NUM1050 CNC system is adopted on FGM320 A CNC Gear Form Grinding Machine. There are 4 servo axes: feed axis X of grinding head; movement axis Z of grinding head, rotary axis A of grinding head and indexing axis C. Axes X, Z and C are full-closed loop control; axis A is semi-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. A dual-worm anti-backlash mechanism is employed for indexing axis C to reach precision indexing requirement.
2. A motorized spindle motor with speed up to 18000 rpm is used for the grinding head, which meets the linear speed need for small grinding wheels and high speed wheel.
3. Based on the data file created with form profile dressing software according to the grinding requirement, the profile dressing of wheel is carried out with a diamond roller through interpolation motion of axes X and Z.
4. The grinding cycle is controlled with CNC system; wheel dressing, compensating and automatic grinding cycle are completed with once programming.
5. A fully enclosed cover, cooling pump with big flow and constant temperature refrigeration device are equipped.
