Starrag has launched the Heckert X70, a versatile five-axis machining centre designed to deliver precision and productivity within a compact footprint. Building on the features of the Heckert HEC X5 series, the Heckert X70 incorporates a swivel unit on the workpiece side, facilitating dynamic five-axis machining from a single clamping position.

Due to receive its world premiere at the EMO 2025 exhibition in Hanover on 22-26 September (stand C35, hall 12), the Heckert X70 offers X, Y and Z-axis travel of 1200 x 1100 x 1200 mm. The compact machine requires 18% less installation space than its predecessor: the Heckert HEC 630 X5. It accommodates workpieces with a core contour diameter of 960 mm and a maximum height of 800 mm, supporting a mass of up to 1000 kg.

Turning is an integral part of the machine concept and can be configured as an option. Using specially developed assemblies and software modules, both classic and complex turning operations are possible with the productivity of a machining centre, reports Starrag. Unlike a turning centre, the machine benefits from various set-up options. Not only can users clamp workpieces vertically for extra convenience, they can also clamp them during the machining operation thanks to the pallet changer.

The Heckert X70’s rapid traverse rate of 65 m/min and fast component changeover times enhance productivity. Pallet changes are completed in 17.5 seconds, while the tool changer provides a chip-to-chip time of 7.4 seconds.

Customers can choose from a range of tool magazine options, including a timing belt magazine with 45 or 60 positions for HSK-100 tools, a chain magazine with a capacity of up to 120 HSK-100 tools, and a tower magazine capable of supporting up to 440 HSK-100 tools.

NCMT has introduced to the British and Irish markets the Makino a500iR, a five-axis, twin-pallet horizontal machining centre that is available with a choice of three spindles. One has a BT40 interface and a maximum speed of 14,000 rpm, while the other two feature an HSK-A63 interface with a maximum speed of 20,000 rpm or 24,000 rpm.

The centre of gravity of the 500 mm square pallet and fixtured workpiece is close to the vertical centreline of the -110° to +180° rotary B axis, enabling high-speed workpiece positioning at up to 267° per second. Notably, the rotating C axis facing the horizontal spindle has an even faster rapid motion of 600° per second. Maximum workpiece size is 900 mm diameter by 600 mm high and the table will accept a load of 400 kg. Linear travels in X, Y, and Z are 900, 750 and 800 mm.

As with all high-performance machining centres, the a500iR generates copious amounts of swarf that is efficiently evacuated by means of slanted panels in the working area and with the assistance of coolant delivered from the spindle head, nozzles and the ceiling of the chamber.

A new feature is the GI (Geometric Intelligence) chip-breaker function, which introduces micro-movements into a drilling operation to break stringy swarf into small chips, avoiding accumulation within the hole and possible damage to the cutter and component. Manufacturers can therefore leave the Makino to run unattended with confidence. Notably, the GI breaker works without impacting the cycle time. This is in contrast to options offered by other machine tool manufacturers, reports NCMT, which tend to lengthen a cycle.
