YKH5132 CNC Gear Shaper

YKH5132 CNC gear shaper is the updated version of the ф 320mm gear shaper series. Along with the existing advantages of the standard ф320mm CNC gear shaper, the machining capacity expands con tinuously, especially for the adoption of the vertical movement (260mm) of the new-type saddle slide.

This is more suitable for cutting deep-hole internal gears and cluster gears. With excellent rigidity, new structure, complete functions and safe and reliable operation, the machining accuracy can reach Grade 6 of the GB standard.

Machine Features
A SIEMENS 828D CNC control system is equipped on the machine to perform 3-axis simultaneous

movements. The cutter spindle is driven by means of the variable frequoncy spindle motor for

the stepless speed changing.

Tool setting and cutter adjustments can be made through an electronic handwheel.
To guarantee high radial positioning accuracy and repeatability, radial feed motions of the column are made through a high precision ball screw.
The slide elevation mechanism uses clamping components made in Germany and an independent middle and high pressure hydraulic station is equipped to ensure the sufficient clamping force.
The position of the clearance groove is precisely controlled when cutting cluster gears.
The control of the corresponding teeth of the cluster gears is easy and practical and high corresponding accuracy can be guaranteed.
Thanks to the 260mm vertical movements of the saddle, parts with both internal and external teeth can be clamped at one chuck, thus improving the machining accuracy and efficiency and saving the amounts of the cutter adaptors and fixtures.
It is suitable to cut super long shaft gears.
A compact conical-shape worktable is used on the machine to facilitate the erection of a loading & unloading device and the prompt chip removal. High-precision radial bearings and highprecision variable-tooth-thickness worm and worm wheel pairs are used to ensure gear cutting accuracy.
A free-standing low-pressure hydraulic station is equipped mainly for the forced lubrication of the saddle and the normal lubrication of the drive box and the cutter relieving mechanism and for the chucking and dechucking of the cylinder for the table rotations. Oil returns to the oil tank quickly and no oil mixture will happen.
The machine has an independent coolant tank for the great volume coolant supply to prolong the service life of the cutter.
Double-cam with special curve and double-roller cutter relieving mechanism is equipped to perform correct, stable, low-noise and reliable cutter relieving motions at high speed strokes. The machine has also the angular cutter relieving function to avoid interference of the cutter and workpiece when cutting internal gears.
