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.
