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.
Simple process considerations can increase your productivity in milling titanium alloys.
By using specialized cutter geometry and incorporating smooth finishes with tough coatings, Toolmex Corp., created an end mill well suited to cut aluminum aggressively. This tool called the "Mako" is part of the SharC line of specialized tools from the same company.
Creating threaded holes in titanium alloys calls for proper techniques based on an understanding of both the properties of these materials and the peculiarities of the tapping process.
