The Heller H 4500 4-axis horizontal machining center features a Heller-produced HSK-A 100 spindle (also available in sk/bt 50 taper), a 500 x 630 mm pallet and 800 mm strokes in X, Y and Z. The machines are also designed for energy efficiency, capable of energy savings of up to 30% compared to conventional machine designs, according to the company.
"The more universal and varied the machining assignment, the more important becomes adaptive power consumption of peripheral equipment and main units in order to optimize power use at various operating points," said Vincent Trampus, Heller Vice President of Sales. "Air, coolant, hydraulics and other energy consumers are flexibly controlled based on demand rather than always turned on. This strategy is called 'Heller Blue'."
"The H 4500 delivers a high degree of precision due to the proven machine concept, the inherently rigid design of the machine bed, the double motor Z-axis, the dynamically stiff, short design of the spindle unit and the water-cooled spindle housing," said a company spokesperson.
"With our new 500 Nm, 52 kW, 12,500 RPM spindle option, the H4500 can provide the low-speed torque it takes for cutting tough materials like iron and steel, as well as higher speeds for machining lighter alloys," said Trampus.
The H 4500 offers a wide range of basic equipment, and each machine can be customized for each user's application. This includes 50/100/150 pocket chain-type magazines for tool lengths of up to 600 mm, tool break monitoring with reference measurement and cleaning of the tool cartridges and holders. Workpiece management is also flexible. The rotary pallet table has a maximum loading capacity of 1,400 kg.
The H 4500 is designed for free chip fall below the spindle and between the rotary table and pallet changer, with steep chip chutes in the work area and at the loading station and a 600 mm wide scraping or flat belt design chip conveyor over the complete Z-stroke.
The machines are available with either Siemens Sinumerik 840D or FANUC 31i-B CNC.
Heller's industry exclusive NC controlled out-facing head option is available on the H 4500 for performing turning operations on the machine. A measuring probe for on-machine part checking, as well as instant tool breakage monitoring, are also available. The machines may be loaded with a robot or other automated loading systems.
