The Toro Series of bullnose polishers from GMM features a body with an electro-welded structure that was machined using CNC technology. The body also receives thermal treatment to unstress materials due to welding.

The surface for the belt is rectified and lined with a stainless steel plate, which can be replaced.

The spindles are the same on all units, with a cover for safety on all moving parts and a double joint for better water and humidity resistance. For the spindles that are subjected to more wear and tear (edges and lower calibration), slight internal pressure is maintained to keep water out from the spindles.

Calibrators, drip cut and multi-functional units can be placed at the entry and exit of the machine. With various configurations, they allow the user to work with the axis in vertical, inclined and horizontal positions. These units can accommodate levigating heads, profiling tools, bushhammering units and discs for cutting. In order for the machine to work at correct speeds, there is a double speed.

The lever is made in strong aluminium casting and oscillates by means of a double reducer and is moved by two brushless motors. By choosing the thickness and the type of profile to be executed, the lever positions itself automatically above the working area on special guides.

The spindles, which are governed by separate hydraulic motors, have various speeds from 2,200 rev/min to 1,000 rev/min starting with the universal diamond tool up to the last polishing grain. A computerized oscillating system allows users to work both on straight edges and different round profiles.

For protection, the covers on the front side of the machine are heavy-duty fiberglass, and the single units feature stainless steel. All of the spindles have a pressure gauge, and separate pressure regulation can be maintained. The operator can also work in automatic or semi-automatic mode.

For long-term ease of use, the machine has been configured to allow for easy normal maintenance and change of tooling.

Additionally, the Costa Series automatic straight edge polisher from GMM features many of the same benefits as the Toro Series, such as the body and spindle advantages as well as the same user-friendly configuration and multiple working modes. The spindles all run on separate motors, and a computerized system allows the user to program the micro-oscillating on the straight edges and pieces with a large thickness. Edges can be polished using universal tools.

Calibrators, drip cut and multi-functional units can be placed at the entry and exit of the machine, and the Costa Series also allows the user to work with the axis in vertical, inclined and horizontal positions. It also allows for multiple tool use and speed settings.
