High Precision CNC Gear Hobbing Machine
GHKA-800 GHKC-800 GHKMA-800
Machine Summary:
Based on the generating process, the model GHKA-800, GHKC-800, and GHKMA-800 CNC gear hobbing machines are capable of producing cylindrical Spur & helical gears, crowing or slightly tapered gears, involute conical splines, gears with large gelical angle; they also have the function of tooth end rounding, as well as producing wormwheels with automatic radial feed. They are used in the industries, such as engineering machinery, heavy automative, tractor, mining machinery, high speed gearboxes, machine tool & general machinery, etc.
The model GHKC-800 machine is especially used for cutting hardened spur & helical as well as hardened crowing or slightly tapered gears. It can be used for cutting shaping cutter, conical splines and gears with large helical angle.
Performance and Feature:
1. The model GHKA-800/GHKC-800/GHKMA-800 machines are of 2-axis CNC one. Their CNC axes includes: X-axis--radial feed, Z-axis--vertical feed, X and Z-axis either work independently, or work coordinately to produce tapered and crowing gears.
2. Various working cycle modes, multi-square and axial working cycle are available.
3. Climb, conventional, climb-conventional and conventional-climb hobbing methods are available.
4. High precision worm gearing are used for the worktable indexing system of the model GHKA-800 to carry out a high indexing accuracy.
5. Our double enveloping worm gearing, which has won the chinese patent, are used for the worktable indexing system of the model GHKC-800. This machine is equipped with a clearance eliminating mechanism.
6. High precision worm gearing are used for the worktable indexing system of the model GHKMA-800 to carry out a high indexing accuracy.
7. Main motor is of AC frequency variable one, and enable a stepless speed control for the spindle.
8. Automatic hob shifting.
9. Separated hydraulic, lubrication and cooling systems.
10. Parameter programming.
11. Standard RS232C interface ensures conveniently calling program from outside computer.
12. Precision ball screws are used for CNC axes. High performance encoders are used for feedback inspecting for the movement of CNC axes to ensure high moving and positioning accuracy of them.
13. Working accuracy of the model GHKA-800/GHKC-800 is up to grade 7.
