Tool Drills, Removes Core from Composites in One Step
Controx Neuhauser introduces its Decoring Cut tooling, which both drills through honeycomb composite panels and undercuts the skins (thus removing the cores) in a single labor-saving step.
Typically, this is a two-step process. First, the upper skin and honeycomb section must be penetrated before the tool interpolates to create a hole in the correct insert size. Then, the panel is manually removed from the machine table for a manual undercut operation.In contrast, the Decoring Cut features an end-tooth design that can cut through the top skin precisely and without delamination. After the plunging operation, the tool interpolates to undercut the skins as deep as necessary to meet aerospace industry norms. A diamond-shaped tooth design ensures the removal and pulverization of the material without “push back,” the company says. The end result is reduced time for core removal, tool changeout and machining; reduced risk of error and defects; and reduced labor costs.
With macros and canned cycles resident in the CNC on most contemporary turning centers, single point turning of OD threads can seem like almost a default process decision. However, for numerous applications, OD thread rolling has inherent advantages as an alternative to cutting threads.
Fast CNC processing and high-pressure coolant contribute to removing metal at dramatic rates. But what should a shop know about cutting tools in high speed machining?
The more common twist drill point geometries often are not the best for the job at hand. By choosing the best point for the material being drilled, it is possible to achieve better tool life, hole geometry, precision, and productivity.
