Introducing the Acra 10" x 54" Variable Speed Vertical Milling Machine, a powerhouse of precision and performance exclusively offered by Omni Machine Inc. This state-of-the-art milling machine is designed to elevate your machining capabilities, delivering unparalleled accuracy, efficiency, and versatility. With its robust construction, advanced features, and user-friendly design, the Acra 10" x 54" Variable Speed Vertical Milling Machine is the ideal choice for workshops, manufacturing facilities, and industrial applications demanding the highest levels of precision and reliability.

The Acra 10" x 54" Variable Speed Vertical Milling Machine is a testament to engineering excellence and cutting-edge technology. At the heart of this machine is a superior spindle unit, available in R8 or NST30 configurations. Made from a single piece of Ni-Cr alloy steel, the spindle is supported by two precision angular contact bearings and one ball bearing, ensuring exceptional rigidity and accuracy. The inner taper is hardened and precision ground for long-lasting performance and repeatability.

The milling head, gear, quill, and body are designed for optimal performance and durability. The hardened and ground spindle ensures quiet and smooth operation, free from noise and vibration. Dynamically balanced pulleys and precision bearings further contribute to the machine's outstanding performance. The powerful 3HP spindle motor provides ample power for demanding milling tasks, while the spindle's back gear runs in a grease-packed housing, minimizing fatigue, enhancing strength, and reducing noise. The chrome-coated and mirror-ground finished quill delivers precise and consistent results, and the Meehanite casting structure ensures structural integrity and stability. The Z-axis box way design allows for heavy-duty work, making this machine suitable for a wide range of applications.

One of the standout features of the Acra 10" x 54" Variable Speed Vertical Milling Machine is its rigid head tilting system. Acra's patented head knuckle design greatly enhances stability and rigidity when the vertical head is tilted at any angle, front or back, allowing for the execution of complex and intricate work. With six T-bolts securing the knuckle to the ram, as opposed to the typical three bolts found in other machines, this milling machine offers unparalleled stability and precision.

The machine also features a unique adjustable backlash nut system, with double nuts and a backlash adjusting design. The enlarged contact face ensures long-term accuracy and easy backlash adjustment, further enhancing the machine's precision and reliability.
