How much does the Johnford HT-100-2SD cost?
Price estimate
We do not have a price for the Johnford HT-100-2SD 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
Top of the HT range by every measure, the Johnford HT-100-2SD has twin turrets, twin spindles and 2,500 mm (98.4 in) between centers. With spindle E it weighs 24,200 kg (53,240 lb), more than any other HT model.
No other HT gives this much Z travel to both turrets with a spindle at each end: 2,500 mm (98.4 in) on Z1 and Z2. The tailstock machine of the same length, the HT-100-2D, limits its second turret to 2,260 mm (89 in).
The outside dimensions are 6,600 x 3,595 x 2,940 mm (259.8 x 141.5 x 115.7 in). Swing over the bed is Ø690 mm (27.2 in), and Ø600 mm (23.6 in) clears the cross slide, with 320 mm (12.6 in) of X travel on each turret.
For very long parts the two spindles act as a pair. A tube can be fed through the main spindle bore, up to Ø236 mm (9.3 in) on variant E, gripped again by the sub-spindle and supported in between by optional hydraulic steady rests. Main spindle speeds run from 3,000 rpm on variant A with the 12 in chuck down to 750 rpm on E. The standard motors are 22 / 26 kW (29.5 / 34.9 hp) and 30 / 37 kW (40.2 / 49.6 hp); 37 / 45 kW (49.6 / 60.3 hp) is the largest option, on C, D and E.
