Price estimate
We do not have a price for the Johnford DMC-900 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 DMC-900 is the smallest double column machining center in Johnford's DMC series: 900 x 900 x 762 mm (35.43 x 35.43 x 30 in) of travel with 1,060 mm (41.7 in) between the columns and a BT-40 / CAT-40 spindle. The table moves in X beneath a fixed bridge, and it is rated for 3,000 kg (6,600 lb).
It should not be confused with the DMC-909. Both have 900 mm of X and Y and a 1,000 x 850 mm (39.4 x 33.5 in) table, but the DMC-909 is a 15,000 rpm mold machine with 500 mm (19.7 in) of Z. The DMC-900 is the general-purpose design. It has 762 mm (30 in) of Z, a spindle nose range of 150~912 mm (5.9~35.9 in), and a geared spindle: the motor row reads 7.5 / 11 kW (10.1 / 14.8 hp) Hi Lo Gear, with a 17 / 20 kW (22.8 / 26.8 hp) built-in spindle as the alternative.
The speed row needs reading with care. Johnford prints 8,000 rpm first, marks 10,000/12,000 rpm as optional, and puts 15,000, 18,000 and 20,000 rpm on a second line that corresponds to the built-in spindle. The accessory list confirms that the 15,000 to 20,000 rpm built-in spindle is an HSK A63 option.
Unlike Johnford's C-frame machines, the DMC-900 has an arm type tool changer as standard, with 24 tools; 32, 40 and 60-tool magazines are optional. Chip removal is by two screw type conveyors and one chain type conveyor with trolley. The machine weighs 10,000 kg (22,000 lb) and stands 3,780 mm (148.8 in) high, which is the dimension most likely to cause trouble in an existing building.
