Mill’s “Oil Shroud” Virtually Eliminates Dust in Graphite Machining
Amerimold 2017: EDM Network will exhibit the HM43GT graphite mill, which features an optional “oil shroud” that virtually eliminates the dust common to graphite milling.
EDM Network will exhibit the HM43GT graphite mill, which features an optional “oil shroud” that virtually eliminates the dust common to graphite milling. EDM-compatible oil captures the graphite dust, and then it is filtered through 2-30-micron cartridge filters. Vacuum compatibility is also available.
The HM43GT and two larger models, the HM65GT and HM86GT, all feature 30,000-rpm spindles with HSKE 32, 40 and 50 tapers, plus optional Blum laser diameter compensation and Fagor glass scales. In addition to graphite milling, the larger models can be equipped with 10- and 15-Kw motors to mill metals as hard as 63 HRC.
Cryogenic machining achieves dramatic tool life gains not by flooding the cut, but by refrigerating the tool.
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.
The recipe for best results is simple: Start with a rigid machine, add a high pressure through-the-spindle coolant system, then combine these with the right drill geometry plus the right speeds and feeds.
