MAKINO A40 HORIZONTAL MACHINING CENTER

Technical Description

The Makino A40 is a high-performance 400mm horizontal machining center designed for precision and productivity in die-cast and general machining applications. It features a horizontal CAT40 spindle capable of speeds up to 12,000 RPM with an optional HSK-A63 taper, delivering 14.75 HP (30-minute rating) and rapid spindle acceleration for efficient tapping and cutting operations. The machine’s table measures 15.7" x 15.7" and supports a maximum workpiece weight of 880 lbs, with 360° B-axis indexing at 0.001° increments for versatile 4-axis machining. The A40 boasts substantial travel capacities: 22" (X-axis), 25.2" (Y-axis), and 25.2" (Z-axis), all with rapid traverse and feed rates of 2,362 inches per minute, ensuring fast and accurate positioning. The tool system includes a 40-tool automatic tool changer (ATC) with a rapid tool-to-tool change time of 0.90 seconds and a chip-to-chip time of 2.2 seconds, enhancing cycle efficiency. Dual pallets are standard, facilitating continuous operation and reduced downtime. Supporting robust and reliable operation, the A40 employs features such as rigid construction, dual-supported ATC mechanisms, and a specialized chip and coolant management system designed for high-volume aluminum die-cast part machining. The machine’s compact footprint integrates single-piece axis covers and advanced control systems to maintain performance and minimize unplanned downtime, making it ideal for precision, high-throughput manufacturing environments.
