The new developments are the Talent P high performance turning centres and the Bridgeport XT travelling beam 5-axis and five face vertical machining centres. Both ranges have been developed by Hardinge using the Global engineering footprint which extends across all continents accessing years of design experience and the manufacturing ability to produce industry leading products, the company says. This philosophy combined with the Six Sigma program within the Hardinge Group ensures the latest complex products are produced to the same high quality across all of its operations, worldwide.

The Talent series machines currently offer two structures (for short and standard lengths) built on a robust one-piece cast iron base with heavy duty roller linear guideways and ball screws. As standard the machines are supplied with ANSI configured Collet Ready spindles available in a choice of 42 or 51 mm capacities. There is also a collet ready sub-spindle with a 42 mm through hole capacity. Other standard features of Talent machines include through tool and headwall air/coolant for both main interfaces and a chip conveyor and bar feed interface. The standard controls are Fanuc OiTF and Siemens 828D.

The Bridgeport XT is the first milling product realised through global engineering and fully complies with the latest ISO Standard 16090-Pt.1 with Functional Safety and the design adopts a travelling beam structure resulting in exceptional geometric accuracy. This design incorporates the 3 linear axes with the cutting tool combined with the rotary and tilt axis table supporting the workpiece.

The innovative travelling beam design represents the first of a new generation of 5-axis machining centres from Hardinge. A large capacity Ø630 mm trunnion table with capacity of 350 kg, coupled with 900 mm swing diameter extends the range of Bridgeport 5 axis solutions. The design and use of twin drive tilt axis is said to maximise the drive stiffness and resulting in high precision.

Thermal distortion effects are minimised by chilled spindles, cooling of ball nuts and end bearings in all linear axis optimising machining accuracy, Hardinge says.
