FRESAT CNC
Adaptable - Technological - Extremely Compact


FRESAT is the name of the first milling machine made by Protek, it is a work center for Nesting and for the series production of parts and panels of large dimensions. The FRESAT is characterized by ease of use, reduced size and versatility of use. The constant work of Protek researchers has made this model with the minimum size, while maintaining the size of workable panels. This allows the diplacement of the machine from a working site to another. The FRESAT, technologically advanced, is equipped with: a console built into the design and mounted on a guide located on the side of the machine with on-board PC and is equipped with Ethernet connection.
