Gear grinder is easier to set up

Gear grinding machine is equipped with a mobile operator panel that makes machine set-up easier and includes dialogue software based on MS Windows operating systems for dressing cycles.
The new S 250 G gear grinding machine completes the Samputensili range of gear grinding machines for economical mass production. Particular attention has been paid to the choice of components used on this machine which have all been thoroughly tried and tested on Samputensili hobbing machines, grinding machines and in automation systems, guaranteeing high performance and reliable results. The cast iron machine bed ensures excellent vibration damping even when large amounts of stock are removed and it was in fact designed for our new S 150 - S 400 series of hobbing machines.

This rigid structure enhances the performance of the direct-drive motors both of which power the tool spindle (rotation speed of 0 - 10.000 rpm) and the workpiece table (rotation speed 0 - 1000 rpm).

The grinding wheel head has been thoroughly tested on the Samputensili S 400 GT grinding machine and is well-managed thanks to the safe tool clamping system.

The tool work area is spaciously designed and the cooling liquid release system is PLC-controlled so that the jet of oil is aimed directly at the tool and workpiece contact zone.

This system also keeps the whole work area much cleaner.

The radial, axial and tangential movements of the axes are performed with the aid of backlash-free, pre-loaded re-circulating ball screws together with a synchronous servo-motor on roller guide ways.

Ceramic worm wheels can be dressed by the diamond dressing roller.

The fully automated system loads and unloads the dressing tool depositing it and collecting it from a specific on-machine tool storage area.

CBN grinding wheels should be used as form wheels.

In terms of automation, the machine is equipped with a fast, innovative, 3-axes CN telescopic loader.

It moves along the longitudinal axis and passes through the machine counter-column so that the loader is always outside the work area during the actual grinding phase.

The control system is the Siemens 840 D with linear and circular interpolation of up to 5 axes and high-performance geometric programming for easy profile and helix generation and relative congruity testing.

The machine is also equipped with a mobile operator panel which makes machine set-up easier as well as dialogue software based on MS Windows operating systems to facilitate the management of data, grinding and dressing cycles and data storage without the need for an external PC.

Other notable safety features of this machine are the interpolated tool withdrawal system in the event of power failure or emergencies which prevents tools from being damaged and the automatic fire extinguishing system which combats the risk of damage to the machine and its surroundings in the event of fire.
