These machines are designed for frequent,practical and efficient grinding in order to maintain cylinders in good condition and ensure optimal grinding result. They feature an electro-welded, non-deformable steel frame to rectify without vibrations High-durability carriage rails are manufactured in steel with tempered chrome. A clutch system enables manual movement of the carriage so it can be moved quickly to the work position, shortening the total time required for grinding. These units have a frequency converter integrated into a control panel that can be installed in different arrangements. Thanks to the simple and compact design, they are very easy to adapt to machines of different configurations.
