The U1250 is a robust machining center for medium-sized parts, with a maximum load capacity of 16,000 kg. It offers milling performance of 42 kW and torque of 1636 Nm. The Y-axis ballscrew is equipped with an internal oil cooling system to ensure high precision.
Its sturdy design includes a rigid column, solid bed and cylinder to enhance precision and rigidity. INA steel tracks on the column and INA roller pads on the saddle maintain precise, stable Y-axis geometry.
Accessibility to the work area is optimal, with operator protection provided by full enclosures that effectively manage swarf and coolant while reducing noise. Balanced design minimizes vibration for high-precision machining.
The LM ballscrew support system with vibration absorber ensures vibration-free operation and reduces noise while maintaining precision. The rigid KORTA ballscrew with hardened Class C3 double-nut screws is preloaded to minimize backlash, offering precise movement and reducing heat distortion on all axes.
The maximum spindle speed of 4000 rpm in continuous operation is guaranteed by high-quality components such as spiral bevel gears (Tandler, Germany) and bearings (SKF, Sweden). The head cooling system is standard, as is the top-quality ZF gearbox. Other features such as the Heidenhain linear scale and a thermal compensation system contribute to the high level of precision.
