Bulky part machining can often become very difficult to integrate into a manufacturing process, when attempting to perform multiple operations on conventional CNC machines. Limited space or axis travel, one-sided spindle or tool accessibility are common restrictions when trying to design and fit multiple tool requirements onto a rigid machine concept. In addition, cycle time demands and accessibility issues from all sides and angles can make a single tool, 3-axis CNC machine option a losing proposition. One new solution involves compact and self-contained single tool Multi-Master flex shaft machining units from SUHNER.
