Heckert 5-axis HMCs offer a modular design that enables the use of different pallets – either 400 or 500 mm in size. Furthermore, spindle and column options allow users to specify versions for either the machining of, for example, aluminium using a universal HSK63 spindle (on a lightweight aluminium column), or titanium using a high torque HSK100 unit (which utilises a steel column). Starrag UK is currently quoting a 12 week delivery timescale for the machines.
Many aspects of Starrag’s existing construction principles are applied to the latest machines, which share a common platform that includes a mineral bed for temperature and vibration resistance. Among further shared technologies are linear guideways, a centralised swarf conveyor, and unified and accessible coolant and lubricant systems.
The Heckert H40, H50 and H55, which offer travel in the X, Y and Z axes of 560 by 650 by 680 mm (H40) and 700 by 750 by 780 mm (H50 and H55), are able to accommodate workpieces up to 900 mm high, and weighing up to 600 kg (H40) and 800 kg (H50 and H55). The 20,000 rpm spindle provides torque values of up to 453 Nm.
Regarding the Heckert L40, L50 and L55, these models come with travel in the X, Y and Z axes of 560 by 550 by 680 mm (L40) and 700 by 550 by 780 mm (L50 and L55). L-series machines are able to accommodate workpiece heights up to 600 mm, and loads of 600 kg (L40) and 800 kg (L50 and L55). The machines feature the same spindle as H-series models.
Lastly, the X40 has travel in the X, Y and Z axes of 700 by 750 by 750 mm, and is able to accommodate workpiece heights of 500 mm and loads of 400 kg. The 30,000 rpm spindle offers torque values up to 350 Nm.
In all cases there is an optional NC rotary table (up to 900 rpm) for performing turning operations in the same set-up, and all machines can be supplied as 4-axis models if preferred. Different tool magazine options are available up to 320 tools, while the 24” CNC touch screen supports the company’s Integrated Production System (IPS) functionality with Profinet and IO-Link integration for networking/digitisation, as well as direct links into ERP software. Starrag’s IPS is applied across all of the company’s product ranges and embraces, for example, cutting force monitoring, and tool and workpiece management.
The company also highlights the productivity advantages of the Heckert linear (L-series) models over twin-spindle competitors. According to Starrag, users of traditional twin-spindle machines typically only achieve productivity levels that equate to 1.5 spindles, due to inefficiencies and the consequences of losing two spindles when the machine stops. In contrast, with L-series models, the productivity from a single spindle is at least 10% higher, says the company.
