CNC Chef: Deep hole drilling

For the 10th episode of The CNC Chef, Bob Warfield of the CNCCookbook discusses the challenges presented when drilling deep holes. Among them: clearing the chips, getting coolant down deep, and holding tolerances on position, diameter and surface finish. As Warfield observes in this episode, "all of this means we need to use some special strategies whenever we have to go more than 5 diameters deep, and that's what this video is all about."

UNISIG tells the deep-hole story at seminar

There were a lot of deep discussions about holemaking at UNISIG's recent open house and seminar series for magazine editors. UNISIG engineers explained different methods of deep-hole drilling, including gundrilling and BTA drilling, and provided an overview of the machines and related systems the company builds to perform these operations. Hands-on demonstrations in UNISIG's 62,000-sq.-ft. plant augmented the classroom discussions.

Whitepaper: The dynamic duo of drilling

Drilling has long been the cornerstone of the machining process, consuming roughly 50 percent of all tools and creating 75 percent of all chips. So it comes as no surprise that shops interested in reducing costs and increasing productivity should look first toward the full optimization of their holemaking processes with today's advanced solid-carbide and indexable-insert drill technologies.

Twin cutter boring head reveals more value over time

Just in time (JIT) manufacturing, by nature, increases setups and shrinks batch sizes. This puts shops in a bind, because more setups and smaller batches are typically less profitable; but saying "no" to work can be even more painful. The burden to search out creative ways to reduce cycle and setup time in order to realize a profit falls to the shops that commonly perform JIT work and on the shops that can't afford to turn it down when the opportunity arises.
