Stonefinisher G2

Compactly built stone finisher for areas from 5mm – 80mm


Stonefinisher G2

Stonefinisher G2

The stonefinisher G2 from techno-finish Industries GmbH has a very compact design and is suitable for surfaces from 5 mm to 80 mm. With the new integrated coolant supply, the process reliability is increased and the finishing time is reduced. The unit can be installed very easily in CNC machines and other large-scale plants without any additional effort.

Like our other equipment models, the stonefinisher G2 is built with standard commercial elements and can easily be adapted to your specific requirements. The processing unit also offers a high degree of flexibility and cost-effectiveness when using custom-made products.

The stonefinisher G2 from techno-finish consists of an oscillating unit of a contact force control and a grinding stone.
With an external, state-of-the-art digital control system from Siemens, with touch panel, operation is made extremely simple, and all error messages are shown as plain text on the display or sent to the higher-level control system.

Superfinishing process

Superfinishing is a material-removing manufacturing process. Optimum surface finish of various machine components is becoming increasingly important and offers unique advantages. The complete surface contact between tool and workpiece is the main difference to classical grinding and turning and leads to the unique characteristics of an optimal surface. Due to the interaction of workpiece rotation and workpiece oscillation, a single grain moves along the sine line, which is characteristic of this process. Bonded abrasives are used in a fixed bond, such as ceramic, or on a flexible backing, such as a textile belt.

This type of superfinishing (surface treatment) optimizes the roughness and waviness of various workpieces, thus reducing wear, generating less friction, lower noise level and increasing the load-bearing capacity of the material to over 90% due to plateau-like surface structure.
