Price estimate
We do not have a price for the Johnford AHC-1600 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 AHC-1600 is a horizontal machining center built around an unusual table: a 0.001° B-axis rotary table of 800 mm (31.5 in) diameter embedded in a fixed flat plate of 1,600 x 810 mm (63 x 32 in). Long parts are clamped on the flat table, which takes 4,600 kg (10,120 lb). Parts that need indexing sit on the rotary section, rated 2,000 kg (4,400 lb).
Travels are 1,600 mm (63 in) in X, 1,270 mm (50 in) in Y and 1,016 mm (40 in) in Z, with the column carrying the Z motion. The spindle centre can be anywhere from 140 to 1,410 mm (5.5~55.5 in) above the table top.
Three spindles are offered. The standard one is a 26 kW (35 hp) unit with a 2 speed gearbox, 0~6,000 rpm and an ISO-50 taper, and the maker quotes 575 ft/lbs at 375 rpm for it. That low-speed torque is the reason to buy the base machine. The first option is an inline direct drive spindle to 10,000 rpm with 26 / 30 kW (35 / 40 hp). The second is an integral motor spindle to 15,000 rpm with 41 kW (56 hp) and an HSK-100A taper. Each step up in speed gives away torque: 122 ft/lbs at 1,500 rpm for the direct drive, 300 ft/lbs at 1,000 rpm for the motor spindle.
Johnford states linear positioning accuracy of ±0.0003 in over full stroke and repeatability of ±0.0002 in, on pre-tensioned Class 3 double nut ball screws. The 40-tool changer swaps tools in 6 sec tool to tool. The base machine weighs 20,000 kg (44,000 lb) and needs 208 / 220 Volts, 3 Phase, 150 Amps and 90 psi air.
