1.Machine overview and main uses:
The six axis CNC gear hobbing machine adopts an electromechanical integrated layout and is equipped with a Siemens CNC system. Six axis control four axis linkage (X, Y, Z) with three linear axes and three rotational axes A, B, and C, where B, C, X, and Z axes are linkage axes.
A - Rotary motion of the tool holder. (Angle of roller wrench)
B - Rolling cutter rotation motion. (Servo axis)
C - Rotating motion of the workbench. (Servo axis)
X - Radial feed motion (the workbench moves forward and backward). (Servo axis).
Y - tangential feed motion (cutter shifting).

axial feed motion (the tool slide moves up and down). (Servo axis)

Z - axial feed motion (the tool slide moves up and down). (Servo axis)

 

This CNC gear hobbing machine uses the generative method to process various spur gears, helical gears, worm gears, small bevel gears, drum gears, and splines through electronic gearboxes. It is suitable for gear processing in industries such as mining, shipbuilding, lifting machinery, metallurgy, elevators, petroleum machinery, power generation equipment, and engineering machinery.
This CNC gear hobbing machine adopts an electronic gearbox (EGB) to achieve gear division and differential compensation motion, which can replace traditional transmission boxes and feed boxes with parameter programming. There is no need for gear division, differential, or feed change gears, reducing tedious calculations and installation.
This CNC gear hobbing machine can use multi head high-speed hobs for efficient and powerful gear hobbing, with a processing efficiency of 2-5 times that of ordinary gear hobbing machines of the same specification. The hob has an automatic tool shifting function, which ensures uniform use of the hob throughout its entire length, thereby extending its service life. The tool holder has automatic turning angle and locking function, which is both accurate and convenient.
This CNC gear hobbing machine has a fault diagnosis function, which is convenient for troubleshooting and reduces maintenance standby time.
