The C 42 U five-axis machining center is available with a mineral cast base to minimize thermal conductivity and vibration. The X, Y and Z axes are 800 × 800 × 550 mm, respectively, with rapid traverse of 60 m/min. in all axes. The spindle features a slim-end design for deep-cavity machining and is available in speeds of 10,000, 18,000 and 25,000 rpm. The two-part spindle design incorporates six displacement sleeves for collision protection.
The tools are changed by direct pick-up, and the magazine accommodates 42 tools with a maximum length of 300 mm and diameter of 90 mm. Tooling is SK 40 and HSK A 63 (the 25,000-rpm spindle utilizes only HSK A 63). The machine features 4.5 sec chip-to-chip time, and tooling can be expanded to 160 pockets.
The machine is designed with a variety of table configurations. For three- and four-axis machining, a rigid clamping table with a 1,050 × 805-mm surface and a load capacity of 2,000 kg is available. Five-axis versions incorporate swiveling rotary tables in three sizes: 800 × 630 mm with a maximum load of 1,400 kg; 440 mm with a capacity of 450 kg; and 420 mm with a 600-kg load capacity.
Controls are Heidenhain iTNC 530 or Siemens 840 D SL, and a variety of options are available for coolant application, chip control and tool management, among others.
The C 50 U machining center is also available for large-part machining.
