How much does the Johnford ST-80CX+B+C+Y cost?
Price estimate
We do not have a price for the Johnford ST-80CX+B+C+Y 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-80CX+B+C+Y pairs a Ø610 mm (24 in) chuck with a CAPTO C8 milling/turning spindle and an 80-tool magazine on 2,000 mm (78.7 in) between centers.
Three things set this column apart from the others in the ST Turn-Mill table. The tool interface is CAPTO C8, an option on the page's accessory list and here part of the specification. The Y axis is offset, -80 / +120 mm, where most columns give ±100 mm. And the axis motors are slightly different: 7.7 kW on X and Z, 4.3 kW on Y and 3.3 kW on B.
Its Y rapid is slow, 2.3 m/min against 10 m/min on X and 12 m/min on Z. Y moves on a machine like this are short positioning moves and off-center milling strokes, so the figure affects cycle time less than it suggests, but it is worth knowing for parts with many Y repositionings.
Turning capacity is Ø850 mm (33.5 in). The main spindle has an A2-15 nose, a Ø152 mm (6 in) bore and Ø139 mm (5.5 in) bar capacity, and a 37 / 44.4 kW (49.6 / 59.5 hp) motor turning it at up to 1,400 rpm through an auto 4-speed gearbox. Tools may be 450 mm (17.7 in) long. At 45,000 kg (99,206 lb) and 9,000 x 5,789 mm (354.3 x 227.9 in), it is a far larger installation than its bed length implies.
