MAKINO G5 HORIZONTAL MACHINING CENTER

Technical Description

The Makino G5 Horizontal Machining Center is a 5-axis CNC machine designed for high-precision grinding, milling, drilling, and tapping operations on complex aerospace and industrial components. It features a horizontal spindle with a #40 taper (optional HSK-A63), delivering up to 12,000 RPM and 33 HP (30-minute rating), optimized for high-speed machining. The machine supports a maximum workpiece weight of 264 lbs on a compact 9.84" x 9.84" table, with axis travels of 20.5" (X), 22" (Y), and 23.6" (Z), all capable of rapid traverse speeds up to 1,890 inches per minute. Its B-axis rotation spans 270°, enabling extensive 5-axis flexibility for intricate geometries. Equipped with an automatic tool changer (ATC) holding 60 tools (expandable to 180), it boasts rapid tool change times of 0.9 seconds, minimizing non-cutting time. The G5 emphasizes thermal stability with integral spindle cooling, core-cooled ball screws, and high-pressure coolant delivery directed precisely for improved grinding and milling accuracy. Its robust construction incorporates a stepped column design, large linear motion guides, and pre-tensioned ball screws near the column’s center of gravity, enhancing rigidity and precision. The machine’s versatile capabilities and automation reduce setups and increase productivity by integrating multiple processes in a single setup. Ideal for aerospace components including turbine blades, the G5 supports complex machining of hard alloys with a maximum tool diameter up to 2.8" (70 mm) and tool lengths up to 15.7" (400 mm), ensuring broad application flexibility in demanding manufacturing environments.
