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.Features:2.1 High quality cast iron is used for castings such as the machine bed, slide seat, tool holder, and spindle box; The bed, slide seat, and knife rest adopt an overall frame symmetrical structure, which has good stiffness, thermal symmetry, and structural stability.2.2 The installation surface of the guide rail adopts a guide rail grinder to clamp and grind it in place at once, ensuring stable machining accuracy; All important cast iron joint surfaces adopt scraping and grinding technology to ensure contact rigidity; The hob spindle and workpiece spindle are precision machined using imported grinding machines, and important surfaces are manually ground to ensure high-precision requirements; All key parts follow strict heat treatment processes to ensure sufficient accuracy retention of the entire machine.2.3 machine adopts precision ball screw pairs and high stiffness, high-precision linear roller guides, ensuring the positioning accuracy and stiffness of the machine tool, making it have advantages such as high precision, strong stiffness, large load capacity, long service life, and no crawling. 2.4 The front and rear supports of the machine tool hob spindle and workpiece spindle group are all equipped with imported multi link high-precision bearings, and precision assembly technology is used to ensure the rotation accuracy of the spindle group; The roller spindle and workpiece spindle bearings are lubricated with maintenance free imported long-lasting grease to ensure long-term stable operation of the spindle.2.5 The gear hobbing machine adopts a fully enclosed or semi enclosed shell structure, ensuring safe operation and clean environment; The main sliding door adopts a rolling guide rail, which is easy to open and close. It is equipped with a safety door lock to improve the operation safety of the machine tool; It has the characteristics of open space, simple operation, and high degree of humanization.2.6 machine is equipped with hydraulic mechanisms such as automatic locking of the cutting tool, automatic release and locking of the pulling angle, and automatic lifting of the rear column bracket. The main hydraulic components are made from KOMPASS products from Taiwan. The guide rail pair and ball screw pair of the machine tool use an independent centralized quantitative lubrication system for precise quantitative lubrication. The lubrication time interval is adjustable, and the system has a liquid level alarm and oil circuit blockage alarm system. 2.7 The CNC system of the machine is equipped with flexible synchronization function, reducing the tedious gear selection and matching; Equipped with human-machine interaction control software, the machining program can be completed by inputting workpiece gear parameters, hob parameters, and cutting parameters according to the interface prompts, reducing the skill requirements for operators. Equipped with an automatic cutter shifting device, extending the service life of the cutter. The tool holder rotates to CNC automatic angle adjustment and automatic loosening and locking, with accurate angle, convenient and reliable. Reduced the labor intensity of operators.
