SAACKE UW I D CNC universal grinding machine was manufactured in Germany in 2020. The extremely powerful machine is designed for the fully automated wet grinding process of a wide range of tools, such as knives, cutters or drills, using grinding discs with a maximum diameter of 250 mm and a length of 480 mm.
Precision machining of workpieces is performed in five numerically controlled axes (X, Y, Z, A, B) in a fully illuminated workspace of the machine with dimensions (L x W) 3000 mm x 2100 mm, located behind a circular sliding door with polycarbonate glass panels. The X,Y,Z axes are seated on sturdy guideways with hardened tracks, and are driven by high-precision twin-nut-pull screws.
The high-tech SAACKE UW I D CNC grinding center significantly increases production efficiency, saves time and reduces costs. It is achieved through the possibility of using a chain or pallet system for automatic tool feeding and processing the workpieces within it in a single production cycle. The storage area, which is separate from the workspace with an automatic grinding wheel changing system, can accommodate up to six grinding wheels with a maximum diameter of 150 mm each.
The SAACKE UWID CNC tool and cutter grinding machine has a wide range of equipment, including a RENISHAW 3D measuring probe for automatic tool positioning and transfer of geometric data to the software, a NUM Flexium Plus CNC control extended with many additional functions and HEIDENHAIN glass measuring rulers. The total weight of the grinder is approximately 4900 kg.
