Through-Spindle Dust Collection For Composites And Graphite
A vacuum system for the machining center draws particulate through the center of the tool.
This video shows a dust-collection system developed by Mori Seiki that draws dust-like chips up through the center of the tool, resulting in clearer air and a cleaner machining environment when the machine is used to mill or drill composite materials or graphite.
The system, called "Zerochip," consists of a high-pressure vacuum system that draws through the centerline of the spindle, as well as special hollow-center cutting tools and a special Zerochip toolholder that includes a bore through the center.
In milling tests using this system in carbon fiber reinforced plastic (CFRP), a 16-mm end mill with PCD edges milling at 2,000 mm/min. feed rate was able to capture 95 percent of the dust generated. This video shows a similar level of collection.
Passivation—the process for making stainless steel parts more corrosion-resistant—is affected by how well the part is cleaned. It’s also affected by the choice of acid. Nitric or citric?
Lockheed Martin’s precision machining of composite skin sections for the F-35 provides part of the reason why this plane saves money for U.S. taxpayers. That machining makes the plane compelling in ways that have led other countries to take up some of the cost. Here is a look at a high-value, highly engineered machining process for the Joint Strike Fighter aircraft.
Simple process considerations can increase your productivity in milling titanium alloys.
