Condition: like new (used), Year of construction: 2023, functionality: fully functional, machine/vehicle number: 282015 SDU8300, travel distance X-axis: 1,500 mm, travel distance Y-axis: 1,000 mm, travel distance Z-axis: 350 mm, feed rate X-axis: 30 m/min, feed rate Y-axis: 30 m/min, feed rate Z-axis: 8 m/min, spindle speed (max.): 45,000 rpm, table width: 1,500 mm, table length: 1,000 mm, total height: 2,200 mm, total width: 2,800 mm, total length: 1,950 mm, type of input current: AC, input voltage: 400 V, spindle motor power: 6,000 W, CNC machine for powerful machining. The steel/granite sandwich construction for the moving axes, such as the gantry and cross slide, can optionally be driven by AC servomotors via ball screws or by linear motors. In conjunction with high-precision linear guides, it forms the basis of the massive steel/granite machine construction. The advantages of natural stone granite combined with high-strength, lightweight metal offer the highest stiffness while simultaneously reducing weight. This is the only way to achieve the desired dynamics and high feed rates. High-frequency spindles with up to 6.0 kW and 45,000 rpm with HSK25 / HSK32 tool holders are used as milling spindles. The 18-position tool changer (expandable to 36 tools), installed outside the working area, automatically moves from the protective housing to the milling spindle. With the 4th/5th axis designed as a swivel head and the integrated, high-precision gear drive modules, almost all positions of a complex workpiece can be reached with the milling tool. The machine is completed with new, state-of-the-art CNC control functions and an easy-to-use user interface. This allows for 5-axis simultaneous machining via RTCP (Rotation Tool Center Point) function. The control and operating components from Heidenhain include a touchscreen monitor and a comfortable handwheel. Different workpiece clamping systems can be mounted on the universal granite table via steel threaded bushings in a 150x150 mm grid. -Innovative steel/granite sandwich construction -State-of-the-art control technology based on Heidenhain -Automatic tool changer with tool measurement/inspection -Optionally with high-dynamic linear motors or ball screw drives -4th/5th axis as a swivel head or rotary tilting unit on the machine bed -RTCP, TLC, axis kinematics and clamping position compensation -Metal/granite sandwich construction -Rotary/swivel swivel head (4th and 5th axis) -High-dynamic linear motors in the X and Y axes -18-position tool changer, expandable to 36 tools -Heidenhain® TNC640 high-end control -Tool measurement by tool setter or laser -3D edge probe -Modern control panel -Water cooling -Heidenhain® LMT TT160 / optional laser measurement -3D measuring probe -Handwheel Lodpfxjzzzylj Aklehl -Minimum quantity lubrication -Tool holders Ideal for machining: Brass Aluminum Ceramics Plastic Copper
