Standard accessories
1. Hob arbor assembly: Φ22, 27mm;
2. Change gears;

3. Tools for installation and set up;
 
Optional accessories
1. Hob arbor assembly: Φ13, 16, 32mm;
2. Chip conveyor;

3. Hydraulic clamping device;
4. Hobbing fixture;


Features 
1. With vertical design, worktable can move in radial as radial feed movement.
2. Electrical system with fail-safe control and low failure rate is controlled by PLC.
3. The module valves have high reliability and low failure rate in order to be convenient to diagnose failures and maintain hydraulic system.
4. The worktable is fitted with double-start worm as its index gearing, therefore is suitable for cutting the workpiece with less teeth.
5. The worktable adopts precision double-end worm gear, hob shifting, high rigidity, good heat stability and may adopt conventional or climb method, achieving semi-automatic cycle
6. The hob spindle adopts circulating lubrication to ensure sufficient and reliable lubrication for spindle bearings in order to prolong the service life. Meanwhile circulating oil can quickly remove heat caused by spindle running to ensure high rotary accuracy for the spindle.
