How much does the Johnford ST-160CH cost?
Price estimate
We do not have a price for the Johnford ST-160CH 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-160CH is the four-metre machine of the 1,000 mm (39.4 in) swing frame with the A2-15 spindle: 4,050 mm (159.4 in) of Z travel, 800 mm (31.5 in) over the cross slide and 24,400 kg (53,680 lb).
On work of this scale a second setup is expensive. Turning a four-metre part end for end means a crane lift, re-chucking and re-indicating, so anything that avoids it pays back quickly. Two options on Johnford's list address it. A sub-spindle or counter-spindle can replace the tailstock, so that both ends are machined in one clamping sequence. And a C axis with a live tool turret, plus the Y axis if needed, takes over drilling and milling that would otherwise go to another machine.
Neither changes the basic turning specification. The spindle has a 152 mm (6 in) bore, 139 mm (5.5 in) of bar capacity and a 200 mm (7.9 in) bearing, and is driven by 30 / 37 kW (40.2 / 49.6 hp) or optionally 37 / 45 kW (49.6 / 60.3 hp) to 1,500 rpm.
The standard tailstock travels 3,600 mm (141.7 in) with a Ø200 mm (7.9 in) MT#7 quill. X travel is 420 mm (16.5 in) and length 9,926 mm (390.8 in).
