G-H series horizontal grinding machines

Our aim is simple: to bring an economic surplus to your daily manufacturing life G 500 H for external and internal gears GP 500 H for roughing and nishing in a single setup with automatic Y axis

The new G-H series of grinding machines for gears, shafts, worms, rotors and screws. One universal solution adapted to your specific application – now for workpieces up to 500 mm in diameter Based on the widely acclaimed S 375 G, the new G-H series presents numerous enhanced features and extends the traditional series to include new model versions. Although Samputensili grinding machines are based on a modular design concept, we craft each and every machine with a wide range of options to suit your individual needs, guaranteeing you the efcient manufacturing of top quality parts.

The new G-H series features an array of innovations and components shared by all machine variants A heavily ribbed structure eliminates the risk of vibration or push and pull phenomena caused by moving machine components. To ensure maximum thermal stability, the machine bed is ooded with recirculating coolant. A new evacuation system transfers swarf from the work area to the ltration unit. Any residue is ushed by additional coolant nozzles so that even the most resistant swarf nests are easily discharged, guaranteeing a clean work area at all times. In terms of work range, workpiece...

Be flexible today and prepared for tomorrow, using electroplated CBN or dressable ceramic tools All machines in the G-H series (with the exception of the GR and GW series) are engineered to mount both dressable ceramic or electroplated CBN grinding wheels. Depending on your lot size and in-house requirements in terms of exibility, efciency, tool costs and surface requirements, you are free to choose the tool technology that best suits you. Electroplated tools designed for you Either ceramic or electroplated CBN grinding tools are available from Samputensili including roughing and nishing...

The G 500 H is the universal and extremely exible base machine of the G series and it is ideal for single pass creep feed grinding of external spur and helical gears, crown gears and shafts, worms, rotors and screw-type workpieces up to 500 mm in diameter. Optionally it is possible to grind spur or helical internal gears. Quick-change spindles and ceramic tool technology, combined with a exible dressing unit and modular software packages guarantee rapid format change and unmatched process versatility. + Universal solution for a wide range of gears, shafts and screw-type workpieces +...

The GP 500 H mounts an additional NC axis, allowing you to work with two separate spindles instead of just one. Both spindles can accommodate one grinding wheel or even two-wheel sets. Single gearings are roughed on the rst spindle and nish ground on the second, with one grinding wheel mounted on each spindle. Two gearings on one shaft can be roughed and nished with wheel sets on each spin- dle without the need for tool changes. Spindle variants are available with different power outputs and speeds for different grinding wheel sizes. Even internal gear manufacture no longer requires tool...

The GT 500 H gear grinding machine is ideal for both prototyping tasks and efficient grinding of medium and large gear batches. With an additonal tool shifting axis, it caters for both profile and continuous generating grinding processes. All standard lead and profile corrections can be generated by a dressing device of your choice, and, thanks to this machine's superior flexibility, you can also apply the most appropriate technology for the given task and even combine different kinds of roughing and finishing processes to maximise efficiency. Plus, with its absolute speed values, the GT...

+ Dedicated version for the manufacture of rotors and screw-type workpieces The GR 500 H has been specically designed for efcient high precision grinding of a wide range of screwtype proles including worms, ball screws, rotors, hydraulic pump screw. The high performance grinding spindle is generously motorised and the machine is designed with an appropriately sized coolant ltration system meaning you can grind workpieces from solid as well as hardened steel. With a dressing unit for ceramic bonded grinding wheels and an integrated checking unit, the GR is perfect for the prototyping and for...

The GRX 500 H is a larger version of the GR. The machine is suitable for the manufacture of very large screws and rotors. Especially adapted to grind with CBN, the GRX 500 H also makes working with dressable ceramic wheels or even combinations of the two easy. An integrated measuring unit also makes the correction on board. For more efcient handling, you can link the GRX 500 H to an external robot device and connect it directly with an external measuring unit. Like the GR, the GRX 500 H comes with a rotor-specic software package, developed under real manufacturing conditions. + Special...
