The Johnford AHC-1600 is our latest horizontal machining center.  Ideal for aerospace application, the AHC-1600 can handle a wide variety of applications in many industries.  With standard accessories, this rigid 35 HP horizontal machining center, weighs in at 40,000 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, which is superior to a moving table / fixed column design, allows for maximum rigidity, better 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 support by the base with absolutely no overhang of the table.  The machine features precision ground and induction hardened box ways in X, Y, and Z.  All mating surfaces are coated with Turcite-B and hand scraped for fit.  The ways are force lubricated via a pressurized automatic oil lubrication system.  Accurate positioning is carried out by large (2.0”) diameter, pre-tensioned ballscrews and powerful servo motors.  Accuracy is ensured by the optional Heidenhain linear scales.
