Johnford FBMC-160 floor-type horizontal boring mills are engineered for precision machining of large parts. The massive machines can be custom-configured to exactly meet specific production needs. Standard axis travels for X, Y, Z, W and V axes are 236″ x 137.8″ x 47.24″ x 39.37″ x 78.74″ (6,000 mm x 3,500 mm x 1,200 mm x 1,000 mm x 2,000 mm). Y axis travel can extend to 196.8″ (5,000 mm) and X axis travel can reach to 591″ (15,011 mm) and beyond.
The machines feature a moving column X axis and both a fixed and a rotary table for the V axis, a heavy duty design that results in maximum rigidity and accuracy. The X axis base is a one piece Meehanite cast iron construction. Roller ways in X, Y, Z, and V have precision Schneeberger 65mm bearings. A pressurized automatic oil system force lubricates the ways. A dual rack and pinion drive moves the X axis and provides high speed rapid traverse of 630″/min (16 m/min) with near zero backlash. Large diameter pre-tensioned ballscrews and servo motors position the other axes. The Y and V axes feature 3.15″ (80 mm)-dia. ballscrews while Z and W feature 2.5” (63.5 mm)-dia ballscrews.
Heidenhain scales are standard in all linear axes. The headstock features a 20.5″ (520 mm) x 17.7″ (450 mm) rectangular ram for the Z axis and a 6.3″ (160mm) bar for the W axis.
The 100 hp, 2,200 rpm main spindle motor has a 3 speed gear drive, and the spindle and headstock are oil cooled to minimize thermal growth.
Standard features include a stand-alone heavy-duty 60 tool arm type automatic tool changer, a comprehensive chip removal system, a high volume coolant system, a full B-axis rotary table with built-in rotary scale, and 300 psi coolant through the spindle.
The standard Fanuc 31iM-B control is suited for all types of general machining applications and provides options for high speed, high accuracy mold and die machining.
