F series sets new standards
Heller has extended its range of machine tools with the launch of the advanced new
F series – a range of machines that it claims, sets new standards in 5-axis machining.
The new series provides complete and simultaneous 5-axis machining and
has been designed with the flexibility needed to adapt to today’s ever changing
manufacturing requirements and to accommodate all production needs.
Two models are available: the FT machines are designed for convenient table
loading, whilst the FP machines are equipped with a pallet changer. Both types are
available with two different work area sizes (2000/4000). Customers can opt for three
different spindle designs on all models: power cutting universal spindle PCU 63 for
high performance cutting, speed cutting universal SCU 63, and the speed cutting tilt
unit SCT 63 with fork head.

force of 13.6 to 136kg. The FCL handles 0/90 prepreg fabric,
±45 prepreg fabric, unidirectional tape and as an option, foil or
film. Maximum material width is 300mm on rolls up to 635mm
diameter and weighing up to 68kg.
The machine features four servo controlled dispensing heads
on a placement carriage that moves on rails integrated with the
vacuum bed. The servo powered placement carriage is driven by
a rack and pinion system.
A Siemens PLC controls the entire process, with speed and
position feedback from rotary and linear encoders on the
dispensing heads and placement carriage. The servo driven
