Product Description

Product Description

2-axis CNC Gear Hobbing Machine YK31125 features:

1. The modular machine concept has been consistently applied to the large machines of this series, guaranteeing an
outstanding cost-benefit ratio and low maintenance costs.
2. Cast-iron machine bed of maximum static and dynamic rigidity with integrated fluid circulation for thermal stability.
3. The worktable is driven high quality, high precision worm and worm wheel gear drive.
4. Linear slides are provided with backlash-free pretension ball screws. AC servo-drives, cast-iron guideways, resin-coated
for optimum vibration absorption. Controlled pulse lubrication is used.
5. With vertical design, the worktable moves to realize feed motion.
6. CNC axes are driven through preloaded ball screws. It can cut gears with crowning and slightly tapered teeth by axial and
radial co-ordinate control.
7. High precision hydraulic components.
8.Equipped with patented double enveloping worm gear to carry out high indexing accuracy.
9. Main guideways are coated with Teflons, the main body is annealed cast structure and solid construction which gives high rigidity.
10. Manual hob shifting
