Applications
Based on the generating process, with carrying out index and differential compensation motions by electronic gearbox, GH800 CNC6 Large-scale CNC Gear Hobbing Machine is designed to cut cylindrical spur and helical gears, crowning or slightly tapered gears, worm wheels and spline etc. GH800 CNC6 odvalovacie are used in the industries, such as mine machinery, marine, crane, metallurgy, lift, petroleum machinery, electricity generation equipment, engineering machinery etc.
Features
GH800 CNC6 odvalovacie is of 6 CNC axes: A--hob head swivel; B--spindle rotation; C--worktable rotation; X--radial feed motion; Y--tangential feed motion (hob shifting); Z--axial feed motion. Four coordinated control axes: B, C, X and Z (or B, C, Y and Z).
Auto overload monitoring and alarm devices for spindle.
Quick retraction protection: in case of power off or failure occurred, synchronously and quickly retract hob.
Symmetric construction of the machine bed ensures stable thermal balance.
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.
Large hydrostatic bearings and super precision double worm gearings system are used for worktable.
Bulky parts are of high rigidity, column is of double-wall, rib-reinforced and symmetric construction,
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.
