Highest precision and productivity for demanding machining requirements
Stable machine base body as the basis for high-performance machining
An outstanding feature of this universal lathe is its stable machine structure. The machine base is designed in a 60° inclined bed construction, which not only guarantees exceptionally high static and dynamic rigidity, but also ensures optimum vibration damping. By using high-quality, double stress-relieved cast iron, the machine minimizes deformation-related production deviations and ensures consistent machining results over the long term. This design is complemented by hardened flat guides with generous contact surfaces, which enable precision and low-wear movement of the axes.

Powerful main spindle for maximum chip capacity
The main spindle of the USC 850 is designed for maximum performance and precision. It is driven by a belt drive with a two-stage transmission, which ensures optimum torque values in both the lower and upper speed ranges.
With a continuous power of 30 kW (30 min. duty cycle 37 kW), the spindle offers the necessary power to efficiently machine even difficult-to-cut materials. The speed range of 10 to 850 min⁻ ¹ in the low speed and 30 to 1,500 min⁻ ¹ in the high speed ensures flexible adaptation to different machining requirements.
Another key quality feature of the spindle unit is its high-precision bearings. The combination of precision angular contact ball bearings and double-row cylindrical roller bearings ensures outstanding rigidity and precise concentricity - even under maximum load. Thanks to precision assembly, dynamic balancing and optimized running-in processes, the spindle achieves concentricity accuracies in the micrometer range.

Versatile turret
The USC 850 universal lathe is equipped with a BMT65 turret, which enables efficient complete-machining of complex workpieces. The turret has 12 stations that are designed for driven tools.
The driven tools achieve motor speeds of up to 3,000 min⁻ ¹ with a drive power of 3.7 kW (5.5 kW / 30 min). This allows not only turning, but also a wide range of milling and drilling operations with the highest precision. The tool receptors are designed for turning tools up to 25 x 25 mm and drilling tools with a diameter of up to 50 mm.
The internal coolant supply, which is fed directly through the turret, is particularly noteworthy. This ensures a targeted cooling system at the cutting edge and improves both the tool life and the surface quality of the machined workpieces. The robust design of the turret in conjunction with precision indexing enables even heavy rough-machining and finishing operations to be carried out with high dimensional accuracy. A hydraulic clamping system ensures exact positioning even with high cutting forces.

Tailstock and steady rests - maximum stability for long workpieces
The USC 850 is equipped with a robust hydraulic tailstock that ensures reliable workpiece support. The quill has a diameter of 150 mm and a stroke of 150 mm. The center point is held by an MK6 taper.
The machine can be supplemented with a hydraulic steady rests for machining particularly long or thin-walled workpieces. This offers clamping ranges from 30 to 245 mm in diameter and enables secure support even with critical workpiece geometries. The tailstock is operated either via the CNC program or manually using a foot switch. The hydraulic clamping forces can be precisely adjusted via adjustable control elements and are displayed digitally.

The USC 850 universal lathe impresses with its combination of high machining precision, robust design and versatile application options. It is the ideal solution for companies that require an economical and reliable lathe for demanding machining tasks.
