1991 MAKINO FNC128 VERTICAL MACHINING CENTERS

Technical Description

The 1991 Makino FNC128 is a 3-axis large-format vertical machining center from the LeBlond Makino FNC series, designed for heavy-duty mold and die machining requiring substantial X-axis travel and high spindle torque. The FNC128 provides 49.2-inch X-axis travel, 31.5-inch Y-axis travel, and 27.6-inch Z-axis travel, served by a 70.9- by 31.5-inch work table with a maximum table load of 6,600 lbs. The heavy-duty CAT-50 spindle operates at up to 3,500 RPM with 25 HP of continuous power, emphasizing torque for heavy roughing in steel, cast iron, and large mold base materials. The A30 ATC configuration provides 30 tool positions with twin-arm exchange. The Fanuc 6MB CNC control, standard for this era of FNC production, provides robust G-code execution with rigid tapping and standard canned cycle support. The FNC128's boxway construction and massive cast iron structure deliver the rigidity required for heavy interrupted cuts and large-workpiece fixturing. The machine occupies a substantial floor footprint of approximately 171 by 195 inches, with a machine weight of approximately 24,000 lbs for the machine unit. The FNC128 represents the upper end of Makino's FNC series travel range and remains a capable platform for shops producing large mold bases, press tooling, and structural die components requiring extended travel and high-torque machining.
