Major machining centre introductions from Hardinge at AMB
The AMB exhibition has seen the European debuts of two major new product ranges from Hardinge Inc., both of which feature significant design and manufacturing innovations.
The two ranges are the Talent programme of high performance turning centres and the Hardinge Bridgeport XT travelling beam five axis and five face vertical machining centres. Both ranges have been developed using Six Sigma data driven methodology which is adopted across the Hardinge operations worldwide.
Features of the machine programmes are sustained high precision with durability and reliability. Both are assembled on base constructions that permit the specification of a wide range of options by departing from the existing structures utilised by Hardinge and others for ‘conventional’ machine design.
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 Hardinge ANSI configured draw tube collet ready spindles available in a choice of 42 or 51mm capacities. There is also a collet ready sub-spindle with 42mm tube 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 control is the Fanuc OiTF CNC control.
The XT range fully complies with the latest ISO Standard 16090-Pt.1 and adopts a travelling beam structure to produce exceptional geometric accuracy. The design also brings together the linear axes with the cutting tool and the rotary and tilt axis table supporting the workpiece.
The large capacity 650ø trunnion tilt table is an important feature having twin drives (positioned each side) to create optimum stiffness at speed, reduced flexing, better positional accuracy, faster response and the elimination of backlash.
Other key features include the enhanced thermal strategies with symmetric structures, chilled spindles, cooled ball nuts (optional) and overall thermal compensation. The control options are a Heidenhain TNC 640 or Siemens 840D or 828D.
On the new introductions, John McTernan, Managing Director, European Sales & Marketing for Hardinge Inc. comments;
“These are genuinely ground breaking machines which exemplify our commitment to producing the highest quality machines for worldwide markets.
Hardinge has assembled a global design team based in the USA, the UK and Taiwan and the team has addressed many fundamental aspects of design criteria to create these new machine ranges.
The result will be families of machines making use of the economies of scale by standardising elements of the construction to create highly competent performance alongside competitive pricing.”
