Specifications & Market Value

This advanced CNC turning center is equipped with a Siemens SINUMERIK 840D control, delivering high-precision multi-axis machining capabilities. It features a main spindle with a 20-inch chuck supporting speeds up to 2,500 RPM and a powerful 70 HP motor (30-minute rating), alongside a second spindle with a 13-inch chuck, 4,000 RPM max speed, and 61 HP motor output to enable complex, simultaneous machining operations. The machine accommodates workpieces up to 27.6 inches in diameter and 78.74 inches in length, with a maximum bar capacity of 4.1 inches. The machine's travel axes include X1 at 25.59 inches, Y1 at ±7.87 inches, Z1 at 80.7 inches, with additional Z2 and Z3 travels each measuring 75.19 inches. The B-axis offers extreme precision with positioning accuracy of ±0.001 degrees and a 240-degree travel range, supporting intricate angular machining. Tooling is managed via an HSK63 interface housed in a 36-station automatic tool changer (ATC). For milling, the spindle achieves speeds of up to 8,000 RPM powered by a 43 HP motor, underpinning multi-technology machining options. The machine’s large footprint measures approximately 299 by 166 by 100 inches and weighs about 52,910 lbs, reflecting its robust industrial-grade construction. This turning center is ideal for high-demand applications requiring tight tolerances, flexible tooling, and multi-spindle machining efficiency typical in aerospace, automotive, and heavy manufacturing sectors. The Siemens 840D CNC controller ensures advanced motion control, dynamic servo control, and integration with Industry 4.0 standards for seamless production automation.
