Schütte in 2000. This machine is specifically designed for high-precision grinding operations and is ideally suited for re-sharpening and manufacturing cutting tools, as well as handling complex geometries. Equipped with a Siemens 840D control system, the machine ensures precise and reliable CNC operations. Generous travel ranges of 400 mm in the X-axis, 400 mm in the Y-axis, and 250 mm in the Z-axis provide ample flexibility for a wide range of tool and cutter grinding applications. Fpsdpfoyrf Trjx Aa Ejd The powerful spindle motor delivers 10.44 kW and enables spindle speeds of up to 12,000 rpm, ensuring efficient material removal and high-quality surface finishes. The machine has undergone extensive technical refurbishment: in 2024, all linear guides were fully renewed, and in 2025, the machine received a brand-new spindle, guaranteeing excellent mechanical performance. Additionally, the machine is equipped with Schütte Integrated Grinding Software (SIGS), enabling precise programming and control of complex grinding operations.
