How much does the Johnford DMC-900H cost?
Price estimate
We do not have a price for the Johnford DMC-900H 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
Johnford's DMC-900H is a compact double column machine with a BT-50 / CAT-50 spindle and a 15 / 18.5 kW (20.1 / 24.8 hp) Hi Lo Gear drive. Travels are 900 mm (35.43 in) in X and Y and 762 mm (30 in) in Z, with 1,060 mm (41.7 in) between the columns.
A bridge frame suits a 50-taper spindle better than an overhung head does. The spindle sits between two columns, close to the crossrail, and cutting forces go down both sides of the structure. That is why this small machine can be offered with spindle options that would be out of place on a C-frame of the same travel: the motor row lists built-in spindles of 26 / 31 kW (34.9 / 41.6 hp) or 31 / 40 kW (41.6 / 53.6 hp) besides the geared drive.
Speeds follow the taper. The row reads 6,000 rpm, with 8,000 rpm marked optional, and 10,000 rpm on the line belonging to the built-in spindle; the accessory list gives 10,000 rpm for an HSK A100 built-in spindle. The spindle bearing diameter is 90 mm (3.5 in).
Tooling limits are those of Johnford's No.50 changers on this series. A tool can be Ø125 mm (Ø5 in) beside its neighbours and Ø200 mm (Ø7.8 in) at most, 400 mm (15.7 in) long, and 15 kg (33 lb). The arm type changer holds 24 tools as standard. Table load is 3,000 kg (6,600 lb) on a 1,000 x 850 mm (39.4 x 33.5 in) surface, and the machine weighs 10,000 kg (22,000 lb). For die blocks and steel plates of under a metre square that need serious metal removal, it is a small footprint to do it in.
