The new H series of hobbing machines for gears, shafts, worms and rotors The H series is designed for demanding automotive applications, like medium-sized ring gears and shafts. It is also suited for producers of any kind of industrial drive. Especially the reinforced R versions are real workhorses for the cutting of gears with highest stock removal rates and the manufacturing of difficult materials. Wherever gears up to 800 mm in diameter are required, we can offer you a solution that suits your specific need. Our aim is simple: to bring an economic surplus to your daily manufacturing life...

Basics first. With innovative concepts and attention to detail A common modular platform is cast from an advanced composite material, which can be made to tighter finished tolerances whilst still guaranteeing the rigidity and thermal stability of conventional cast iron, fundamental in demanding gear hobbing processes. The machine structure is also coolant-flooded to enhance rigidity and keep temperature deviations to a minimum. The inclined planes of the work area prevent the build up of chip nests. Chips are evacuated immediately via an integrated conveyor and do not come into contact with...

productivity H 250 machines automated with ringloader and workpiece magazine with 50 stations. Very long or heavy workpieces are worked without compromising quality H / CD series 5

H 250/300/400 at a glance + All state-of-the-art hobbing and milling techniques The H 250 and its larger sisters have been specically developed for dry hobbing and high speed cutting applications. The machine is available in 3 different sizes up to 400 mm in diameter with a variety of different heads and table designs. The H-series guarantees highest productivity for exible small batches or for mass production of spur and helical gears, crowned and tapered gears, worm gears, chain wheels and ring gears, multiple gears, pinions and special proles. 6 H / CD series The machines employ all...

H 250 CD at a glance The H 250 CD is based on the modular H-series of hobbing machines. Its integrated chamfering/deburring unit deburrs gears and shafts up to 250 mm in diameter. Both processes are actuated time-parallel with minimum auxiliary times. Workpieces are changed by a fast 4-station ring loader which positions workpieces directly on the magazine or conveyor band. 8 H / CD series The chamfering/deburring process is completely integrated in the process chain by CNC and controlled by a unified, easy-to-use operator interface. The chamfering deburring unit uses Samputensili...

HMI-PRO Maximum productivitiy on minimum space The H 250 CDM is the ideal combination of full-scale hobbing and chamfering/ deburring within an extremely compact unit. With its space-saving dimensions this solution allows the manufacturing of straight and helical gears and pinion shafts in a fast and efcient manner. The modular construction principle enables the user to hob as well as chamfer/ debur dry or wet. Both processes run Hobbing with HSS hobs coated with new Sunite® Alcrona. 12 H / CD series H 250 CDM parallel to avoid unnecessary auxiliary and support times as much as possible....

CDM at a glance + Horizontal workpiece axis for easier debris fall. Less clogging of tools which results in longer tool life and improved quality of the workpieces integration + Automatic meshing between tools and workpiece + Quick-clamping system for revolving and directly-driven tools + Motorised work spindle with continuously variable speed + Adjustable tailstock allows adaptation to the workpiece geometries to be machined The H 250 CDM is controlled by the Siemens control 840 D, with both processes – hobbing and chamfering/ rolling/deburring – completetly integrated via HMI-Pro. A...

The H 250 R is the strongest, hightorque version within the H 250 series. Its sturdy hob head is driven by a high torque drive for applications with large modules and tooth depths which require higher cutting forces. The H 250 R is also tted with a countercolumn extension in order to clamp longer workpieces like rotors and long shafts. H 250 R For more efcient handling, the H 250 R can be tted with a heavy ring loader or can be directly linked to an external robotic loader. The H 250 R is available with a rotorspecic software package, developed under real manufacturing conditions. at a...

The H 600 / 800 is a very stable and rigid machine for the most demanding cutting taks. The machine employs all hobbing techniques (axial, radial/ axial, tangential, diagonal) of spur and helical gears using one or multiple cut technology with climb or conventional feed exploiting the different tool solutions available on the market. H 600/800 For workpicees with larger modules and tooth depths the H 600 is also available as a reinforced version featuring an extra high-torque hob spindle, an enlarged swivel angle range, and an extended countercolumn to cut long and slim shapes like rotors...
