MAKINO A7 HORIZONTAL MACHINING CENTER

Technical Description

The Makino A7 is a high-performance 5-axis horizontal CNC machining center engineered for precision aerospace and large-scale component manufacturing. This machine delivers exceptional capability with generous work envelope dimensions: 276 inches X-axis travel, 106 inches Y-axis travel, and 40 inches Z-axis travel, accommodating aerospace structural parts up to seven meters in length. The A7 features a powerful 33,000-rpm HSK-F80 spindle generating 107 HP (80 kW) output, capable of chip-removal rates up to 5,400 cc/min for aggressive metal removal. The 60-tool automatic tool changer with 19.7" x 19.7" pallet configuration enables extended unmanned machining cycles. Makino's proprietary patent-pending Volumetric Accuracy Compensation technology ensures sustained dynamic accuracy through in-process tool-tip corrections, critical for complex three-dimensional geometries. The machine's rigid 5-axis design provides efficient force path distribution, minimizing structural deflection and maximizing cutting performance throughout the full Y-stroke. The A7 is specifically optimized for aluminum machining and excels in aerospace applications requiring high-speed precision work on large monolithic parts. This CNC horizontal machining center combines rapid spindle speeds with robust construction to deliver the accuracy and repeatability demanded by aerospace and heavy machinery manufacturing sectors.
