How much does the Johnford ST-60AH cost?
Price estimate
We do not have a price for the Johnford ST-60AH 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 ST-60AH is a 1,200 mm (47.2 in) lathe with the fast A spindle on the H frame, which gives 920 mm (36.2 in) of swing over the bed and 700 mm (27.6 in) over the cross slide.
The optional chuck makes more sense on this frame than on the standard one. A 381 mm (15 in) chuck with tall jaws and a wide part leaves comfortable room under a 700 mm (27.6 in) swing, and the 370 mm (14.6 in) X travel lets the turret reach the outside of it. With that chuck the speed is 2,500 rpm; with the standard 304 mm (12 in) chuck, 3,000 rpm or 2,800 rpm depending on the bar capacity chosen.
Bar capacity is 91 mm (3.6 in) as standard and 102 mm (4 in) as an option through a 115 mm (4.5 in) bore. The motor is 22 / 26 kW (29.5 / 34.9 hp) with an Auto Hi-Lo transmission.
Axis drives are 7 kW on X and Z, and rapids are 15 m/min and 18 m/min. The tailstock travels 900 mm (35.4 in). Weight is 12,100 kg (26,620 lb), against 12,000 kg (26,400 lb) for the ST-60A, and the length is 6,195 mm (243.9 in) on a 60° slant bed.
