How much does the Johnford HT-30-2SD cost?
Price estimate
We do not have a price for the Johnford HT-30-2SD 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
Two spindles and two turrets in a 5,100 mm (200.8 in) machine: the Johnford HT-30-2SD is the smallest HT lathe that can cut two sides of a part at the same moment.
Both spindles are the 8 in unit of the small HT frame, with a Ø203.2 mm (8 in) chuck, A2-6 nose, Ø51 mm (2 in) bar capacity, 11 / 15 kW (14.8 / 20.1 hp) and 4,500 rpm. Each turret has 12 stations and 175 mm (6.9 in) of X travel. With a dual-path control system as standard, the upper turret can work at the main spindle while the lower one finishes the previous part in the sub-spindle, so the second operation costs no extra cycle time.
The price of fitting all of that into the short bed is Z travel: 460 mm (18.1 in) on Z1/Z2, less than the 550 mm (21.7 in) of the single-turret HT-30-2S. Distance between centers is 550 mm (21.7 in). Parts for this machine are short: bar-fed pieces, small forgings, slugs cut from Ø51 mm (2 in) stock.
Rapids are 15 m/min on X and 18 m/min on Z and W. The turrets are non-driven as supplied; a live tool turret in BMT or VDI, a C-axis and a Y axis on the upper turret are options, as are a bar feeder interface, a parts catcher and a conveyor belt for parts. Weight is 7,500 kg (16,500 lb).

Frequently Asked Questions
01
Twin spindles and twin turrets. The machine has a main spindle, a sub-spindle in place of the tailstock, and two sets of 12-position direct-mount non-driven turrets under a dual-path control system.
02
Johnford's tables give 460 mm (18.1 in) for the HT-30-2SD and 550 mm (21.7 in) for the HT-30-2S, on the same 550 mm (21.7 in) between centers. The tables do not state the reason; the 2SD carries a second turret within the same machine length.
03
Main and sub-spindle are alike: Ø203.2 mm (8 in) chuck, A2-6 nose, Ø65 mm (2.6 in) bore, Ø51 mm (2 in) bar capacity, one-step drive, 4,500 rpm and 11 / 15 kW (14.8 / 20.1 hp).
04
The equipment for it is optional: a bar feeder interface or bar feeder system, a parts catcher and a conveyor belt for parts are all on the optional accessory list. A chain type chip conveyor with trolley is standard.
