Drive for flexible shafts - MB 20/3 G

It is not only being able to change the belt so quickly that makes this belt grinder so distinctive. You can grind an area using the telescopic arm and then change to grinding a point on the rubber roller with the fixed grinding arm. This can be done very easily with a clamping screw. In addition, the machine is available, entirely in accordance with your requirements, with grinding arms for belt widths of 8, 15 or 20 mm. Changing them is easy and requires little effort.

Developed for slight to heavy grinding and milling for tool and mold making, as well as for deburring, fettling and brushing work in foundries, container and steel construction and mechanical workshops. The lightest and most compact machine in its class for the toughest jobs. * Unbeatable power-to-weight ratio with 2.8 kW at 34 kg. * Ultra-strong asynchronous motor ("continuous runner") with top efficiency. * Indestructible, absolutely maintenance-free, virtually no wear. * Particularly suitable for large tool diameters. * Ideal for working on large surfaces. * Motor overload protection. * Constant speed under load. Comfort and safety features: * Wide range of possible combinations for shafts and handpieces. * Machine can be operated free standing, on table stand or on travelling stand. * Restart protection. * Soft start. * Protection class: IP 55, protection class: I

The unique belt guide system allows the use of very small belt widths without the belt coming off the roller. The tensioning system ensures continual tension in the belt thus contributing to the safety of the guide system. Available in lever or rotary valve variants. Individual work through the rotatable head. Furthermore it has a protective cap for safe handling.

Milling, grinding, brushing, polishing, filing – and all with a single device! This all-rounder is suitable for use in almost all sectors of industry The best results are achieved through digital sensorless control electronics. This ensures: * Consistently high torque at any speed between 5,000 and 15,000 rev/min. * Constant speeds at different loads. * Retrieval of power reserves: at maximum load a remarkable peak power of 1.5 kW. Above this the machine is shut down by the overload protection. * No pulsation in the low speed range. * Work results in smoother surfaces. Low maintenance costs and no unnecessary downtime * The motor is protected from overloading by an automatic cut-out. * Automatic cut-out if wear occurs to the carbon brushes. * Fully encapsulated sensorless electronics cannot be clogged with metallic particles. * Electrical surge protection prevents current peaks and protects the motor. Delivers the highest attainable degree of occupational safety and comfort.
