DMG SAUER ULTRASONIC 20 LINEAR VERTICAL MACHINING CENTER

Technical Description

This high-performance 3-axis machining center features an 8.0 in X-axis, 8.75 in Y-axis, and 11.25 in Z-axis travel, providing precise and versatile machining capabilities. It is powered by a robust 20.0 hp spindle motor capable of speeds up to 40,000 RPM, with optional configurations reaching 60,000 RPM, supported by a 4.43 ft-lbs torque rating for efficient material removal. The machine utilizes an HSK32A taper spindle interface, known for high precision, rigidity, and dynamic balancing suitable for high-speed machining. The tool magazine accommodates 24 tools with optional expansions to 40 or 60 tools for enhanced productivity. The 10.0 in by 10.0 in table supports a maximum load of 33.1 lbs and has a diameter of 9.84 in, accommodating workpieces up to 7.09 in in height. The machined parts are facilitated by rapid traverse rates of 131.2 ft/min along all axes, enabling quick positioning and reduced cycle times. Overall machine dimensions are 80 in by 65 in by 93 in, with a substantial weight of 8,300 lbs ensuring stability during operation. The system incorporates a coolant pan (60 in x 23 in x 11 in) weighing 350 lbs to manage thermal conditions. Ultrasonic machining capabilities are supported with frequencies ranging from 15 to 55 kHz and a maximum amplitude of 0.00039 in, enhancing cutting precision on difficult materials. The machine logs indicate 36,061 operational hours with 19,703 spindle hours, demonstrating extensive usage and reliability. This machining center is engineered for high-speed, precision applications combining durability, rapid tool change, and fine control for complex machining tasks.
