Both the Alpha 1660XS and 1760XS machines offer an 18.5 kW motor with 105 mm spindle bores (the 1760XS model has an optional bore of 155 mm), delivering a spindle speed of 2,000 and 1,400 rpm respectively. Both models are of cast iron construction and can be specified with a centre distance from 1.5 to 4 m.
The Alpha 1660XS and 1760XS are fitted with the same Fanuc 0iTD/Harrison Alpha control system as the rest of the range. Through the proprietary Harrison control, this allows four ways of working – from manual turning through to full CNC production.
