The design of bed-type milling machines includes a stable machine bed. While large and heavy parts can result in instability with knee-type machines, bed-type ones can hold their ground. The long bed means that multiple parts can be attached onto the bed at once, diminishing idle times and increasing the efficiency on the workfloor.
