Unlike pressure-basedWe learned that the pressure ofConsider an application in which shop personnel need to deliver a lot of coolant to a cutting tool, so they set the coolant pressure to 1,000 psi. But he said they actually have no idea how much flow will be going through the drill.If its clogged with chips or if the hole in the end is too small or any number of other things, they might only be getting a very small amount of flow through the drill, Fettig said. In that case, theyre going to break that drill.On the other hand, the UNEs programmable system ensures that enough energy is put into the pro-cess to produce the necessary cool-ant flow.We might say that for a (certain) size drill we want 3 gallons a minute through that tool to carry the chips awayand we dont care if it takes 200 psi or 2,000 psi to get that flow through the drill, Fettig said.Many manufacturers either avoid parts that require gundrilled holes or attempt to produce them with 10,335,870 machining centers, which he said harms the production process.So we see our machines as a perfect complement to production cells and also as a way to add a (special) capability to your shop, Fettig said.CTEabout the author William Leventon is a contributing writer for CTE.
