Machines built with this structure utilize a rectangular, prismatic construction for the base, column, and saddle. This design provides a robust and rigid framework, often employing Turcite-B coated surfaces for enhanced damping and wear resistance. Typically, these machines are driven by ballscrews and utilize servo motors for precise axis movement. A representative example might feature a machine with travels of X = 1000 mm, Y = 500 mm, and Z = 600 mm, along with a powerful spindle capable of various machining operations.
The inherent rigidity of this configuration provides excellent stability, particularly beneficial for heavy-duty cutting of ferrous materials. This stability translates to increased accuracy and improved surface finishes. Historically, these machines represented a significant advancement in machining technology, offering higher precision and the capability to handle heavier workloads compared to earlier designs. Their durability and reliability have made them a mainstay in many manufacturing environments, especially those involving large or complex parts.
