It is stiffened by welded triangular plates across the entire machine bed, making it extremely stable. The triangular shape used for load-bearing parts, with a large base, is the secret to ensuring lasting precision and stability. The machine layout allows the user an optimal workflow despite minimal space requirements. The base body constructed in this way therefore offers the machining unit a balanced and secure base with particularly good load distribution. The mobile unit carrier in gantry design is made of a solid monoblock. It is positioned in the X direction on prismatically ground guides via recirculating ball slides. The work unit is mounted on this mobile unit carrier on prismatic, ground guides and a recirculating ball slide. Axis movement: The drive system in the Y and Z axes is provided by ground ball screws of the highest precision class. The X-axis is driven by a backlash-free, preloaded precision rack and pinion drive. This ensures balanced load distribution during the positioning process. Such characteristics are important for ensuring balanced movement even in more complex tasks. The movement of the various axes is controlled by brushless three-phase servo motors/brushless AC motors. These offer excellent positioning speeds thanks to very short ramp times. Furthermore, the measuring system is fully integrated into these motors. These properties make this type of drive completely maintenance-free. · Rapid traverse in X: 40 m/min · Rapid traverse in Y: 60 m/min · Rapid traverse in Z: 22.5 m/min Vacuum system (basic) · Vacuum pump: 100 cbm/h · Power: 2.5 kW · Max. negative pressure (connection) 0.9 bar Control / control cabinet · Office PC or industrial PC (see options) · Basic NC control: ESA-GV KVARA 6.0 · Cable remote control with the most important functions ELECTRIC/ELECTRONIC CNC CONTROL Universal is equipped with a powerful NC control.

Technology, the toughest spindle available on the market, with over 1,000 maintenance-free hours of use. Better and more comprehensively equipped, with various configuration options thanks to the multifunctional table to optimally equip the machine according to your needs. Easier and more understandable programming thanks to the integrated MAESTRO CNC CAD-CAM module. Easier to use: the work table is accessible at all times, the electrical cabinet and vacuum pump are integrated, and in the PRO SPACE configuration there are no guards. Supporting structure. The supporting structure consists of a particularly strong monolithic steel base, heavily ribbed and very rigid. The particularly wide support was specifically designed to give the machine stability, ensuring consistent precision regardless of the working conditions and eliminating the need to anchor the machine to the floor. The base forms a large and solid support for the mobile column: the work unit is thus equipped with a balanced, stable, and durable support that can withstand the most extreme stresses, ensuring higher quality performance and greater precision. The mobile gantry consists of a single, solid unit anchored to the base on both sides and slides on pyrotechnic guides with top-quality ball-return slides. The dual motorization along the X-axis ensures top performance even under demanding working conditions. The movement of the lower moving unit (X-axis) and the working unit along the rod of the moving unit (Y-axis) is achieved thanks to a rack/pinion transmission with helical teeth. this creates a greater tooth-to-tooth thrust which achieves greater acceleration and greater speed along the X and Y axes. The specially designed helical gearing ensures less wear on the mechanical components and less noise. The vertical Z axis is driven by a screw with ball return which ensures perfect balance with dynamic loading and strong acceleration and deceleration. The main milling unit is directly coupled to the Z axis carriage and ensures absolute quality of finishes as any vibrations are completely eliminated. Translation along the X-Y-Z axes is carried out by brushless motors driven by static inverters; These ensure: - Reduced processing times thanks to improved acceleration - Better positioning accuracy thanks to the high-resolution encoder - Zeroing of setup operations when switching on the machine thanks to absolute encoders - Zeroing of general maintenance operations since there are no brushes with the "brushless" system The management of the axis displacement and, in general, of the machine's working elements is carried out by an industrial NS module with digital D Lrjdpfx Ahsvvi N Iezog
