HELLER Machine Tools has introduced the top range of its 4-axis H Series horizontal machining centers, the H 14000. "This large capacity machine combines a robust machine design with the structural stiffness and high torque required for making the deepest cuts in the toughest alloy steels and irons," said a company spokesperson. "Developed over many years as a machine provider for large diesel engine component machining solutions, HELLER's H series is ideal for machining large pumps and housings for power and fluid transmission.
"The capacity of the H Series machines to make roughing cuts throughout the day while providing finishing accuracies for X/Y/Z positioning of 0.010 mm (according to VDI/GDQ 3441) make them ideal for large, difficult to machine alloy steel and iron components." According to the company, feed forces of 20,000 N make the machines capable of making demanding cuts.
The HELLER H 14000 is the top of the H-series and features a work area of 2,400 x 1,600 x 1,600 mm in X/Y/Z over a 1,000 mm pallet designed to handle a 4,000 kg workpiece load. HELLER has also minimized positioning times by focusing on realistic dynamic rates of 40 M/minute in all axes.
HELLER's NC controlled out-facing head is available on the H 14000 for performing feedout operations on the machine such as taper boring, generating pockets and compensating diameters. A measuring probe for on-machine part checking and instant tool breakage monitoring are integrated. "The machines, consistent with efficient cell operation, are designed for manual or can be easily adapted to FMS systems or other automated loading systems," said the spokesperson.
With a high-power cutting (HPC) gear-driven head stock, the H 14000 offers maximum torque of 2,292 NM and generating 60 kW of power at low RPM with options available for rigid face clamping for right angle milling heads. HSK 100 spindle taper is standard with a choice of chain type tool magazines for tools up to 800 mm in length or rack type magazines with tool lengths up to 1,000 mm.
"The precision provided by all machine sizes in the H range is ensured through reduced table deformation and high precision due to internally arranged drives and linear scales," said the spokesperson. "This provides high productivity and minimal axes positioning times resulting in reductions in machining times between 20 and 50 percent in practical application.
"At HELLER, chip disposal is critical," continued the spokesperson. "The H 14000 is designed with three chip augers that rapidly move chips out of the work area and into the chip conveyor, delivering the chips to the chip hopper."
To support its global customers, HELLER machines are equipped with either Siemens Sinumerik 840D or FANUC 31i-B CNC.
