New JOHNFORD DMC-3100SH (STOCK) | 5-Axis Gantry Machining Centers (incld. Bridge & Double Column)

Description

The Johnford DMC-3100SH is the heaviest double column machining center in its class. With standard accessories, this heavy duty 35 HP fixed double column vertical machining center, weighs in at 72,160 lbs. of Meehanite cast iron. The machine design features a moving table and fixed column for maximum rigidity. A rugged 90 degree bridge with offset Y axis ways and a massive 40” wide saddle keeps the spindle center line extremely close to the bridge for rigidity. This design also allows for more distance across the Y axis ways for best support of the massive headstock.

The massive Z axis head and Y axis saddle features square box ways coated with Turcite and have been designed with diagonally arranged ribs that will help reduce the amount of distortion that is caused by years of continued service. The X axis table traverse is accomplished via heavy duty Schneeberger roller linear ways for accurate positioning of heavy work pieces. Accurate positioning is carried out by large diameter, pre-tensioned ballscrews and powerful servo motors. The X axis ballscrew is stationary and uses a spinning ball nut to position the table, eliminating ballscrew whip and minimizing vibration.

The 90mm spindle is driven by a 35HP, 2 speed geared spindle drive that delivers outstanding cutting performance at any RPM. The spindle is oil cooled for minimal thermal growth. A 6000 RPM spindle driven by a 2 speed gear box and producing 488 ft./lbs. of torque is standard. For high speed machining, both a 35HP 10,000 RPM direct drive spindle or a Weiss integral spindle is available as an option A Weiss integral spindle is available as an option. The 110mm Weiss spindle produces 15,000 RPM and 56HP with excellent low end torque and utilizes HSK-100A tooling for best rigidity and tool life.

An impressive list of standard features includes a heavy duty 40 tool arm type ATC that is separated from the machine for easy maintenance, a complete chip removal system consisting of 2 screw type conveyors on each side of table empty into a lift up type conveyor at the end to discharge into a hopper, a high volume coolant system, and complete guarding around the machine to contain chips and coolant.

Your choice of Fanuc controls provides the ideal combination for all types of application. The Fanuc OiM-F Plus control is standard while the Fanuc 31iM-B Plus control is optional to provide the precise solutions for a wide variety of applications. The OiM-F Plus is suitable for a variety of job shop and mold type applications while the 31iM-B is a high speed CNC system that is the best available for high speed machining of three dimensional surfaces and other demanding needs.
