Large Scale CNC Gear Hobbing Machine
GH-800CNC6 GH-1250CNC6
Machine Summary:
Based on the generating process, with carrying out index and differential compensation motions by electronic gear box(EGB), the model GH-800CNC6/GH-1250CNC6 heavy-duty gear hobbing machine is designed to cut cylindrical spur & helical gears, crowning or slightly tapered gears, worm wheels, splines, etc. This machine is used in the industries, such as mine machinery, marine, crane, metallurgy, lift, petroleum machinery, electricity generation equipment, engineering machinery.
Performance and Feature:
1. The machine is of 6 axes with four axes coordinated control. CNC axes:
A-axis--hob head swivel;
B-axis--spindle ratation;
C-axis--worktable rotation;
X-axis--radial feed motion;
Y-axis--tangential feed motion(hob shifting);
Z-axis--axial feed motion;
Four coordinated control axes: B,C,X and Z.
2. Carry out index and differential compensation motions by the electronic gearbox(EGB).
3. Fulfill heavy duty and powerful cutting by multi-start & high speed hob.
4. Productivity of the machine is 2 to 5 times higher than those general ones that of the same specifications.
5. Fault diagnostics function.
6. Auto. overload monitoring and alarm devices for spindle.
7. Quick retraction protection: in case of power off or failure occurred, synchronously and quickly ratract hob to avoid collision.
8. Parameter programming.
9. Symmetric construction of the machine bed ensure stable thermal balance.
10. Adopt large power AC spindle motor, power is transferred to cutter spindle by high precision helical gearing. Adopt a one-tooth difference clearance eliminating mechanism to improve transmission accuracy and rigidity. Equipped with auto hob arbor clamping device.
11. Large hydrostatic bearings and super precision Chinese patent double worm gearings system are for worktable, ensure the worktable has high static & dynamic rigidity and rotation accuracy, and driving with free-clearance.
12. Bulky parts are of high robust and rigidity, column and workstay are of double-wall, rib-reinforced and symmetric constructions, satisfy the needs of high speed and high efficient cutting.
13. Guideways for axes X,Y and Z are of ample hardened steel guideway, linear recirculating roller guidance systems are preloaded, ensure the guideways have high rigidity and accuracy. X, Y and Z axis are closed-loop controlled by linear enconder, ensure machining of stability dimension of the workpiece.
14. Adopt PROFI-BUS DT. Reasonable arrangement of pipelines and cables fully ensure the reliability of the control system.
15. Separated hydraulic, lubrication and cooling systems.
