Machine Description:

     N60 type 5-axis, 6-axis CNC gear hobbing machine is a gear hobbing machine controlled by 5 or 6 CNC axes. N60 type CNC gear hobbing machine is equipped with Higerman CNC system, which can process gear shafts, gears (spur gears) by generating or indexing. , helical teeth, drum teeth, synchronous teeth, bevel teeth, etc.).

The machining accuracy can reach GB/T10095-2008 grade 6 and GB/TT2363-1990 grade 6 standards, especially suitable for batch processing of small high-precision gears.

Machine features:

■ Full CNC  Using Higerman CNC system, each motion axis of the machine tool is CNC controlled and B, C, X, Z are the linkage axes, and the electronic gearbox (program) completes the tooth division movement, feed compensation movement, and differential feed compensation movement when cutting teeth. , increased the functions of the machine tool (such as hobbing small tapers and drum gears, etc., it became extremely simple); shortened the transmission chain, and at the same time adopted semi-closed loop or full closed loop control, the positioning accuracy and repeated positioning of each axis can be improved through numerical control compensation Therefore, the machining accuracy and Cp value of the machine tool are improved, and the reliability of the machine tool is increased; when changing varieties, it saves the time for calculating and changing the gear and differential gears, feed and spindle gear shifting. The auxiliary processing time is reduced and the flexibility of the machine tool is increased.

■ High Efficiency   The machine tool has a high-speed tool spindle and a high-speed worktable, while ensuring high rotation accuracy (radial runout accuracy ≤ 0.002mm, axial runout accuracy ≤ 0.002mm); greatly improve cutting efficiency; suitable for multi-head hob Powerful high-speed cutting with large amount of cutting, high processing efficiency; Adopt built-in hydraulic chuck locking device and flange-type tooling installation.

Double and multiple gears with different modules, different numbers of teeth, different helix angles and different helix directions can complete the hobbing of the teeth under one installation, and can also mill grooves with a single index;

■ High Precision   A large number of imported famous brand accessories are used to improve the speed, accuracy and reliability of the machine tool. The accuracy is guaranteed and improved under processing conditions;

■ High Rigidity   The machine body is made of HT300 gray cast iron with excellent wear resistance and shock absorption. It has been annealed twice to ensure dimensional stability and prevent deformation and cracking. The machine tool adopts imported HIWIN, which has a preloaded, backlash-free ball screw-driven feed system and an imported roller-type linear rolling guide with damping and preloading, which does not require maintenance and maintains high precision for a long time. Worktable indexing Adopt worm gear pair and damping mechanism with eliminating clearance;

■ Functional Compounding   The workpiece can be processed in multiple processes in one clamping, thereby improving the processing efficiency and even the accuracy of the workpiece, such as: automatic feeding, gear hobbing, secondary gear hobbing, multi-process gear hobbing, deburring, and automatic blanking;

■ High Degree of Automation   With automatic loading and unloading, automatic clamping device, 24-hour continuous working ability;

■ Environmentally Friendly   Install the oil mist separator so that only the mist without oil is discharged;

■ Intelligence and Informatization   The combination of digital control technology, sensor technology, information technology and network control technology makes CNC gear processing machine tools more intelligent. Realize the functions of error compensation, anti-collision function, overload protection, tooth meshing, machining allowance allocation, tool wear, zero programming interface, multi-function machining software, automatic identification, remote control, and remote diagnosis when robots move workpieces between machine tools ;

■ High Flexibility   Short preparation time for mass production;
