New JOHNFORD AHC-1600 | Horizontal Machining Centers

Description

The Johnford AHC-1600 is our latest horizontal machining center. While 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.

The standard 6000 RPM 50 taper spindle delivers outstanding performance throughout the RPM range. The spindle is supported with the highest class of precision bearings to ensure optimum accuracy and to provide a stable platform for heavy duty cutting. The 35HP main motor with 2 speed gear drive ensures outstanding cutting performance at any spindle speed. The spindle and gearbox are oil cooled for minimal thermal growth. A range of spindles are available including 10,000 RPM direct drive 50 taper spindles and the German made Weiss / Siemens high speed, high power 15,000 RPM HSK-100A spindle. For heavy cutting and fine finishing together, the 110mm diameter shaft 15,000 RPM HSK-100A spindle with 56HP and 300 ft/lbs of torque is an excellent choice. The spindle features ceramic bearings with Vogel air/oil mist lubrication for best life. The spindle and headstock are liquid cooled for minimal thermal growth.

An impressive list of 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 4 screw type conveyors (2 parallel with the Z axis, 2 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 800mm full B axis rotary table built-in. The Fanuc OiM-F Plus control is standard and provides the ideal combination for all types of general machining applications up to 4+1. The optional Fanuc 31iM-B control control is available for more demanding high speed machining applications as well as 5 axis simultaneous contouring. Mitsubishi, Siemens, Fagor, and Heidenhain controls are also available.
