This Hermle C 42 U is a used five-axis machining center — sometimes referred to as a CNC machining center or multi-axis machining center — from 2014. Machining centers are precision machine tools designed to perform multiple metal-cutting operations such as milling, drilling, boring, and tapping on a workpiece within a single setup, making them central to high-accuracy manufacturing in aerospace, automotive, medical, mould-making, and general engineering industries. Hermle is a German machine tool manufacturer with a longstanding reputation for building high-precision five-axis machining centers widely used in industries where tight tolerances and complex part geometries are required.
The machine is equipped with a Heidenhain TNC 530 control system and configured across five axes. The circular table has a diameter of 440 mm and accepts five T-slots with a T-channel width of 14H7 mm, with a maximum swing circle of 990 mm. The A-axis swivels through a range of +130 to −130 degrees, and the table operates at a speed of 30 rpm. Traverse strokes are 800 mm on the Y-axis (transversal), with rapid traverse rates of 45 m/min longitudinally, 45 m/min transversally, and 40 m/min vertically.
The spindle uses an HSK-A63 interface and reaches a maximum speed of 18,000 rpm, delivering a maximum torque of 148 Nm. Coolant is supplied through the spindle at 80 bar, supporting demanding cutting applications. Tool management is handled by a magazine with 42 places in the primary carousel and an extended capacity of 160 places, giving a total tool storage figure consistent with long-running automated production.
A key feature of this configuration is the integrated KUKA loading robot paired with a pallet station offering 54 spaces, enabling highly automated, lights-out production cycles. Workpiece measurement is provided by a Blum system, and tool break control is also handled by a Blum unit, supporting in-process quality assurance without manual intervention.
Electrically, the machine requires a 400-volt, 50 Hz three-phase supply with a total power demand of 37 kVA, and it connects to a compressed air supply at 6 bar. The machine weighs approximately 12,500 kg.
