How much does the Johnford HT-40-2D cost?
Price estimate
We do not have a price for the Johnford HT-40-2D 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
On the Johnford HT-40-2D the two turrets do not travel the same distance. Z1 is 1,000 mm (39.4 in) and Z2 is 760 mm (29.9 in), on a bed with 1,000 mm (39.4 in) between centers and Ø750 mm (29.5 in) of swing.
That split is the first thing to plan around. One carriage covers the full length of the part; the other stops short, so a tool on the second turret cannot follow the first all the way along a full-length shaft. Balanced roughing is possible over the shared stretch, and beyond it the long-travel turret works alone.
It is a big machine for its length. Swing over the cross slide is Ø600 mm (23.6 in), each X axis travels 320 mm (12.6 in), and the tailstock quill is Ø200 mm (7.9 in) with an MT#7 taper and 200 mm (7.9 in) of travel. Tailstock travel is 700 mm (27.6 in).
The headstock is ordered as one of five variants. A and B, with A2-8 and A2-11 noses, take 22 / 26 kW (29.5 / 34.9 hp) through an Auto Hi-Lo transmission. C, D and E all use an A2-15 nose and 30 / 37 kW (40.2 / 49.6 hp) with four automatic steps, and run at 1,200 rpm, 1,000 rpm and 750 rpm. Machine weight is 17,000 kg (37,400 lb) with spindle A.
