How much does the Johnford HT-80-2D cost?
Price estimate
We do not have a price for the Johnford HT-80-2D that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
The Johnford HT-80-2D is a 2,000 mm (78.7 in) twin-turret lathe with a tailstock, and the size at which the HT range moves its Z axes to 7 kW servo motors. The X1 and X2 axes stay at 4 kW.
Long shafts are the job. Z1 travels 2,000 mm (78.7 in), Z2 travels 1,760 mm (69.3 in), and the tailstock moves 1,700 mm (66.9 in) along the bed before the 200 mm (7.9 in) quill stroke. With two carriages on a part this long, one common arrangement is to let each turret work its own half so that neither has to cross the whole bed at 15 m/min.
A shaft of two metres will usually need more than a center at the far end. The quill is Ø200 mm (7.9 in) with an MT#7 taper, and Johnford lists its own manual steady rests and hydraulic steady rests with manual travelling or a CNC motor among the options. For deep bores there is an independent boring bar system with a holder of over ɸ100 mm on the lower guideways.
Swing is Ø710 mm (28 in) over the bed and Ø600 mm (23.6 in) over the cross slide. The machine is 6,000 mm (236.2 in) long and weighs between 21,000 kg (46,200 lb) and 21,200 kg (46,640 lb) according to the spindle variant.
