New JOHNFORD DMC-5100LH+5FACE | 5-Axis Gantry Machining Centers (incld. Bridge & Double Column)

Description

The Johnford DMC-5100LH five face machining center features a rigid vertical and a detachable horizontal spindle for 5-sided machining of large parts. It 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 121,000 lbs. of Meehanite cast iron. The machine design features a moving table and fixed column for maximum rigidity. A massive 90-degree bridge with huge box ways keeps the spindle center line extremely close to the bridge for rigidity. This design gives a full 48” span across the Y axis ways for best support of the massive headstock. The large box type Z axis ram provides 42” of Z axis stroke and excellent rigidity.

Our five-face head features a full 360-degree rotation ability with minimum increments of 5 degrees. The head, which is automatically attached and detached, is stored in its own cradle located outside of the machining envelope. The head is locked in position by a face gear coupling for rigidity and accuracy. The ATC system works with both the vertical and horizontal spindles for truly automatic operation. Both CAT-50 spindles are driven by a 35HP Fanuc high torque spindle motor and 2 speed ZF gear box that delivers outstanding cutting performance at any RPM. The vertical 6000 RPM spindle is oil cooled for stability and long life.

The massive bridge and traveling head feature 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 table traverse is accomplished via 65mm heavy duty Schneeberger roller type linear ways for accurate positioning of heavy work pieces. Accurate positioning is carried out by large diameter, pretensioned ballscrews (3.15” X ) and powerful servo motors. The X axis ballscrew is a stationary screw / spinning ball nut design which greatly reduces whip and vibration and minimizes axis inertia.

An impressive list of standard features includes a heavy duty 40 tool arm type ATC, 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 table to contain chips and coolant.

The Fanuc OiM-F Plus control is standard to provide the necessary features for most applications and to promote programming power and ease of operation for most general purpose uses. The Fanuc 31iM-B Plus is a high-speed CNC system that has the power for a variety of applications including high speed machining of three-dimensional surfaces. It can be equipped with the up to 1000 blocks of look ahead and a variety of other options.
