Machine Description:

NAIGOO N150 CNC gear hobbing machine is a 5 axis /6 axis vertical CNC gear hobbing machine, can be developed or indexed by the way of processing gear shaft, gear (straight teeth, helical teeth, drum teeth, etc.), worm gear, with gear, spline, etc. N150 CNC hobbing machine is equipped with a HIGERMAN CNC system, electronic gear box (EBD) function and self-developed hobbing software, man-machine dialogue interface, without system programming, directly fill in the form of input related parameters can be processed.

With strong rigidity and stable precision, the machine can be used for high speed dry cutting, high speed wet cutting and hard tooth surface cutting. Widely used in gear reducer, power tools, intelligent settlement, motorcycle and other industries of tooth processing.

Machine Features:

S full numerical control adopt Higerman numerical control system, the movement axis CNC machine tool control and B and C, X, Z for the joint axis, performed by electronic gear box (program) teeth tooth movement, feed movement of compensation and differential feed compensation movement, increased the function of machine tools (such as gear hobbing small taper and drum become extremely simple); By shortening the transmission chain, the positioning accuracy and repeated positioning accuracy of each axis can be improved through numerical control compensation after using semi-closed loop or full closed loop control, so as to improve the machining accuracy and CP value of the machine tool and increase the reliability of the machine tool. The time of calculating and changing the gear hanging wheel and the differential hanging wheel, feeding and the spindle shifting are eliminated when changing the variety, thus reducing the auxiliary processing time and increasing the flexibility of the machine tool.

■ High efficiency machine with high speed tool spindle and high speed of the worktable, while ensuring high rotation accuracy (radial runout accuracy ≤0.002mm, axial movement accuracy ≤0.002mm); Greatly improve the cutting efficiency; It is suitable for high speed cutting with multi-head hob with strong cutting capacity and high processing efficiency. Adopt built-in oil pressure chuck locking device and flange type fixture installation.

Double and multi-coupling gears with different modules, different numbers of teeth, different helical angles and different helical directions can be used to complete the tooth rolling in a single installation, and can also be used for single degree milling.

■ High precision adopts a large number of imported famous brand accessories to improve the speed, accuracy and reliability of the machine tool. High precision has high rigidity linear guide rail, ball screw, rolling bearing, precision spindle, servo motor and numerical control technology with pre-loading, so that the accuracy of the machine tool can be guaranteed and improved under the condition of high speed machining;

■ The body of the high rigidity machine is made of HT300 grey cast iron with excellent wear resistance and shock elimination. After two stress relief annealing, it ensures dimensional stability and prevents deformation and cracking. The machine tool adopts imported HIWIN with a pre-loaded, no-backlash ball screw driven feed system and adopts imported roller type damping and pre-load linear rolling guide, without maintenance and maintain long high precision, the table is divided by the elimination of clearance worm gear worm pair and damping mechanism;

■ Functioned composite workpiece can be completed in a single clamping process, so as to improve the processing efficiency and accuracy of the workpiece, such as: automatic feeding, gear hobbing, secondary gear hobbing, multi-process gear hobbing, deburring, automatic blanking;

■ High degree of automation with automatic feeding, feeding  automatic clamping device, 24 hours continuous working ability;

Environmentally friendly installation of oil mist separator, so that the discharge is only oil-free fog;

Intelligent and information digital control technology, sensor technology, information technology and network control technology together to make the intelligent level of CNC gear machining machine tools higher. It can realize the functions of error compensation, collision prevention, overload protection, tooth meshing, machining allowance distribution, tool wear, zero programming interface, multi-functional processing software, automatic identification, remote control and remote diagnosis when the robot is moving the workpiece between machine tools.

■ High flexibility to achieve short preparation time for mass production;
