Introducing the Acra 4V Heavy Duty Bed Type Vertical Boring & Milling Machine, a rugged and versatile machine designed for precision machining in demanding industrial applications. With its robust construction, advanced features, and superior accuracy, this vertical boring and milling machine delivers exceptional performance and reliability, making it an ideal choice for manufacturers seeking to optimize their machining processes and achieve superior results.

The Acra 4V Heavy Duty Bed Type Vertical Boring & Milling Machine is a state-of-the-art machine that combines power, precision, and user-friendly features to streamline your machining operations. The table and saddle, constructed from high-quality cast iron and stress-relieved, provide a stable and durable foundation for accurate machining. The hand-scraped and finished way surfaces ensure smooth and precise movement, while the large supporting surface and narrow square guide ways contribute to exceptional stability and cutting efficiency. The feed box offers both power and manual operation, allowing for easy speed changes and a wide range of speeds to accommodate various cutting requirements. The backlash eliminator, a standard feature on the table feed system, enhances operating stability and cutting efficiency. The table and saddle's upper, rear, and front reference surfaces are ground, and the T-slots are accurately machined, ensuring flatness, parallelism, and squareness that meet the highest standards for convenient workpiece setup and operation.
