H 800
The machine with a stable and rigid construction is designed for the most hard hobbing tasks. Method of one or two passes performed in forward or backward direction allows manufacturing of straight and helical gears at one machine. The machines are equipped with automatic ring loader for quick changing of workpieces. The integrated technology with power milling head guarantees high efficiency.
- Stable and rigid construction of the machine is suited for the most of processing tasks with high requirements
- High torque of the hob head (1,000 Nm)
- Compact and ergonomic placement of machine components
- Work table with direct drive
- Wet (with coolant) and dry processing
- Fully integrated internal auxiliary units
- Ring loader (option)
- Optional PowerCutting equipment
Integrated auxiliary units
- Hydraulic and media units are seen through big viewing windows of doors
- The machine can be transported without dismounting of its components
- Quick and cost-effective installation and adjustment
- The machine can be quickly transported when replacing of production
Power, precision and power-efficiency
- Backlash drive of high-precision double worm gear
- High quality with even acceleration and feed even at low rotary speeds of the work table
- High power-efficiency in comparison with direct drives
For processing of parts with large modules and tooth height Modul machines with PowerCutting option are recommended. This option includes a high-capacity hob head with enlarged swivel angle.
- High torque 1500 Nm
- Drive with water cooling
- Big size of mills – up to 300 mm
- Enlarged swivel angle
PowerCutting hob head provides maximal utilisation of capacity of mills with swivelling cutting inserts. Depending on size of batch and cost of tools the parts are hobbed or form milled. PowerCutting hob head and corresponding special equipment are especially recommended for milling of parts with large modules, teeth with nonstandard height, gears with large angles of inclination, hardened or ductile materials and especially long or heavy workpieces.
Form milling of internal gears
- Optional milling head for processing of internal gears
- Depending on gear width the milling head arm is extended due to enlarging of drive chains and transmission steps
- Milling is more effective than gear shaping
Manual clamping of workpiece
- Clamping of internal gears
- Clamping of external gears
Automation with a help of ring loader
- Ring loader with two or more stations
- Two axis, one of which is CNC-controlled
- Hydraulically controlled ring loader movement
- Independent movement of clamping unit
- Max. workpiece weight 150 kg
