Introducing the New 12-1/2" x 58" Acra's Variable Speed Vertical Milling Machine, a robust and versatile machining solution designed to deliver exceptional performance and precision. With its heavy-duty construction, advanced features, and variable speed capabilities, this milling machine is an ideal choice for manufacturers seeking to optimize their machining processes and achieve superior results.

The New 12-1/2" x 58" Acra's Variable Speed Vertical Milling Machine is engineered for durability and precision. Constructed with MEEHANITE cast iron for the machine base, knee, and table, this milling machine offers exceptional stability and rigidity. The heavy-duty milling head assembly can be rotated 90° to the right and left, providing enhanced flexibility for complex machining operations.

The machine features dovetail ways on the X-axis and square ways on the Y and Z axes, ensuring smooth and accurate movement. The slide ways are hardened and precision ground to HRC48-HRC52, guaranteeing long-lasting performance and resistance to wear. Chromed and hardened lead screws with double nuts on the X, Y, and Z axes provide precise positioning and minimize backlash. The X and Y axis surfaces are coated with Turcite-B for enhanced durability and smooth operation.
