Asquith Butler Open House to Feature Mill-Turn Capability and Volumetric Compensation System

The one remaining UK manufacturer of large capacity machine tools, Asquith Butler, has announced that its next biennial open house exhibition will take place at its Brighouse manufacturing facility and technical centre from 4th to 6th December 2012, 9.00 am until 4.00 pm each day. Anyone wishing to attend should contact Paul Hinchliffe, Managing Director, email tel: 01484 726620.

Visitors will be able to see for the first time a new compensation system for volumetric positioning accuracy, developed for use on large machine tools by the University of Huddersfield's Centre for Precision Technology in close collaboration with Asquith Butler.

The system will be demonstrated at the show integrated into an Asquith Butler POWERCENTRE - 500 MT travelling-column, horizontal-spindle, mill-turn machining centre, which has 8 m x 2 m x 1.5 m linear travels and a 30 tonne capacity, 3 m diameter turning and positioning table. The compensation system is claimed to reduce geometric errors by up to 90 per cent over the entire working volume, despite the machine having already been produced to very tight tolerances.

The open house will also provide a first opportunity to see in action Asquith Butler's recently launched mill-turn capability, with the STARTURN - VTG (Vertical Turning Gantry) and POWERCENTRE- 500 MT (Horizontal Mill-Turn) 6-axis machining centres capable of achieving micron tolerances in both milling and turning modes. The machine ranges are based on the long established STARCUT and POWERCENTRE series of 5-axis machining centres to which has been added a large capacity turning / positioning table of 3, 4 or 5 m diameter.

In addition to live cutting demonstrations on new equipment, there will be used machines on show, including a 5 m Butler Elgamill HE that is currently undergoing comprehensive electrical and mechanical refurbishment and CNC retrofit. Key equipment suppliers co-exhibiting will be Fanuc, Siemens, Heidenhain, Renishaw, Sandvik, Cytec Systems and CNC Rotary.
