TRENS SN 71C HORIZONTAL MACHINING CENTER

The TRENS SN 71C is a robust horizontal machining center designed for precision turning of large workpieces in piece and small-lot production environments. Featuring a single main spindle with a maximum turning diameter of 27.000" (685.8 mm) and a maximum turning length of 77.000" (1,955.8 mm), this lathe excels in handling oversized components with high stability and accuracy. The main spindle chuck diameter is 12.500" (317.5 mm), supporting a wide range of workholding options, while the maximum spindle swing reaches 27.900" (708.7 mm), allowing for versatile machining configurations. The spindle operates at speeds up to 1,000 RPM, driven by a 10.0 HP (7.5 kW) motor, ensuring efficient material removal and smooth operation across a broad range of materials. The machine is equipped with a standard four-way tool post as the primary tool carrier, enabling quick tool changes and supporting one simultaneous cutting tool. With two controlled axes (X and Z), the SN 71C provides precise control over both cross and longitudinal feeds, offering a longitudinal feed range of 0.05–6.4 mm/rev and a cross feed range of 0.025–3.2 mm/rev. Rapid traverse rates reach 3,000 mm/min longitudinally and 1,500 mm/min crosswise, enhancing productivity. The spindle bore measures 73.5 mm with an internal metric taper (Metric 80), and the spindle nose conforms to ISO 702/III-B8 standards. The lathe also features a tailstock with a Morse 5 taper, a wide selection of thread cutting capabilities, and a comprehensive set of accessories for enhanced functionality. Designed for durability and ease of maintenance, the TRENS SN 71C is a reliable solution for demanding turning applications.
