Hermle C 42 U 5-axis machining centre with turning facility
1 min read
Hermle's C 42 U is a 5-axis machining centre with a 800 by 800 by 550 mm working envelope, it is ideal for applications in the tool and mould, medical, aerospace, motorsport and other industries requiring complex, close-tolerance components.
The machine is also offered in MT (mill-turn) version, whereby turning operations at 800 rpm or less can be carried out in the same clamping using the C-axis table mounted on a ± 130 degree swivelling A-axis trunnion. Parts can weigh up to 700 kg, half the maximum possible (without turning) on machines configured for 5-axis machining.
Alternatively, a 3-axis machine can be supplied with a fixed table capable of supporting parts over one metre long and weighing two tonnes.
The spindle features Hermle's slimline design to facilitate machining of deep cavities and is available with maximum speeds of 10,000, 18,000 or 25,000 rpm offering up to 29 kW of power and 200 Nm of torque. The two-part design incorporates six displacement sleeves that collapse to prevent damage to the spindle in the event of a collision.
Construction of the C 42 U lends itself to the addition of high precision turning. Bearings for the A-axis are set directly into the mineral cast bed, promoting stable, vibration-free machining, particularly as the trunnion is driven from both sides by motors positioned on the axis centreline. The table, with integral balancing system, is driven by a high torque motor optimised for comparatively high speeds, making it possible to perform combinations of robust roughing and light finishing operations.
Control system is either Heidenhain iTNC 530 or Siemens 840 D SL with 19" screen and 30 degree tilt.
The C 42 U machining centre is available in the UK through Hermle's sole agent, Geo Kingsbury Machine Tools.
