Heller Machine Tools

Heller’s model HF 5500 5-axis horizontal machining center (HMC) is equipped with pallet changer and offers a work envelope of 900mm x 950mm x 900mm and a maximum pallet load of 750kg.

The horizontal spindle offers quick tool changes and short idle times. Three linear axes in X, Y, and Z are equipped with absolute measuring systems and two direct-drive dynamic rotary axes in A and B integrated into a swivel rotary table.

An optional Speed-Dynamics Package provides 10 % shorter chip-to-chip times. For an additional reduction in idle times, the HF series provides a high-speed NC tool changer with lift-and-swivel principle.

The use of a counter bearing in combination with a YRT bearing results in high rigidity for handling high loads.

The machine is either available in table design or equipped with pallet changer with a choice of spindles to suit different applications.

The standard version is equipped with the SC63 SpeedCutting motor spindle with HSK-A63 (18,000rpm, 100N-m), for machining light metals. The optional PC63 PowerCutting spindle unit (12,000rpm, 201N-m) provides torque for high-performance cutting of cast iron and steel.

As further options, with HSK-A100, the SC 100 spindle unit (12,000rpm, 201N-m) provides increased stability of tools and high speeds for universal application, and the PC 100 spindle unit (10,000rpm, 354N-m) offers high torque for use with large and heavy tools.

The workpiece interference contour of model HF 5500 was increased by 800mm in height and 900mm in diameter compared to model HF 3500. The machine enables swivel movements of the rotary table through 150° (30° to -120°) and with certain restrictions, even through 225°.

The Heller Operation Interface, the new operating panel with 24" screen and touch controls and XTENDS optional expansion applications support the user.

The new machining centers enable continued use of existing tools from other Heller machines and the use of manual clamping fixtures. Adaptation of hydraulically operated clamping fixtures is also possible.
