Moving Column Combination Table-Type HMC

Johnford's recently introduced AHC-1600 horizontal machining center (HMC) is suitable for a variety of applications in many industries, particularly aerospace.

The HMC features a combination 63" x 32" flat table with an 800 mm full B-axis built-in rotary table. With standard accessories, this 35 HP HMC weighs in at 44,000 lbs. of Meehanite cast iron. The machine design features a moving column for the Z-axis and a moving table for the X-axis only. This design allows for increased rigidity, enhanced accuracy and full support of the table over the complete X-axis travel. The moving column design eliminates the need for outriggers or outboard supportive ways to support high table loads. The X-axis is fully supported by the base with no table overhang. The machine features precision-ground and induction-hardened box ways in X, Y and Z axes. All mating surfaces are coated with Turcite-B and hand scraped for fit. Large (2.0") diameter, pre-tensioned ballscrews and servomotors provide accurate positioning.

The standard 6,000 RPM 50 taper spindle delivers robust performance throughout the RPM range. The 35 HP main motor with two-speed gear drive is designed to ensure enhanced cutting performance at any spindle speed. The spindle and gearbox are oil-cooled for minimal thermal growth. Standard features includes a heavy-duty 40 tool arm type ATC that is stand-alone and separated from the machine for easy maintenance, a chip removal system consisting of four screw type conveyors (two parallel with the Z-axis, two parallel with the X-axis), a high volume coolant system, full machine enclosure guarding to contain all chips and coolant and a combination 63" x 32" flat table with a 32" (800 mm) .001° full B-axis built-in rotary table. X-axis longitudinal travel is 63" (72", 79", 118" optional), Y-axis vertical travel is 50" and Z-axis column travel is 40".
