Starrag Swivel head adds fifth dimension to HMC
Switzerland – With an NC swivel head providing a fifth axis, the Heckert HEC 500 D U5 MT horizontal machining centre provides effective and efficient single set-up production embracing turning as well as milling and drilling, Starrag announced.
In addition to reduced cycle times, the machine is said to provide accurate machining, thanks to the thermo-symmetrical design as well as minimised operating costs via efficient drive, hydraulic, pneumatic, cooling and control systems.
With X, Y, Z traverses of 750 mm by 700 mm by 725 mm, and traverse rates of 65 m/min, the HEC D U5 MT can accommodate loads of up to 600 kg (500 kg when turning). According to the supplier it comes with a range of spindle motors, from a 37 kW/ 350 Nm torque version up to a 50 kW unit that can attain 20,000 rpm.
Furthermore, the head can be positioned to an accuracy of 6 arc-seconds within the -15° to 195° swivel range, to provide contouring in conjunction with the 900 rpm NC rotary table and involving B- and C-axis routines. According to Starrag, the head is particularly suited to inclined drilling. With a 60-tool automatic tool changer as standard and claimed chip-to-chip times of 3s, plus a pallet change time of 10 s, the machine can be used individually or within manufacturing cells with pallet storage or integrated elements of a flexible production system.
