The ConJet high-density bed jet mill is a spiral jet mill combined with a patented dynamic air classifier. This classifier enables the ConJet to achieve highest finenesses independent of the product load, and therefore also highest throughput rates. Applicable for finenesses from 2.5 to 70 m d97. Machine sizes available for grinding air volumes from approx. 50 to 2,400 Nm h.
tools with surfaces that are free of grinding marks and scratches. Alloys containing more than 10 Si are the most difficult to machine because hard particles of free silicon cause rapid tool wear. Alloys containing more than 5 Si will not finish to the bright machined sur-
this reason alloys have been developed in which tellurium, sulphur or lead have been added to the pure copper as chip-breaking alloying elements. The conductivity of these alloys is only 1tate of the art S Fig. 1 Comparison of the machinability of copper alloys with a free-cutting steel and an aluminium alloy
Common types of nickel-alloys include Inconel, Hastelloy, Waspaloy, stainless steels including 304, 316 and 17-4and others. Given a sharp tool and the right cutting parameters, pure nickel is not terribly difficult to turn or mill, although nickel alloys such as Ni-Span-C 902 and Monel K-500 bear machinability ratings of 15 percent or less.
The use of cold tooling which rapidly chills the metal can be as harmful as not preheating the material. The best method for machining that involves metal removal is E.D.M. The following conventional methods can also be used with great care Grinding, forming, joining, milling, riveting, spinning, stamping, and turning. Back To Pure Tungsten.
Mar 27, 2015 The milling system is specially designed to handle the autogenous grinding media with specialty separators to keep the grinding media in the mill while allowing the fines to pass. Like its wet milling counterpart listed above, the autogenous grinding mill can make particles up to a fineness of less than 1 micron in aqueous or solvent slurries.
Both wire and sinker EDM can be used on Tungsten Alloy materials. EDM surfaces can experience hydrogen embrittlement and grain removal. Grinding. Use aluminum oxide or silicon carbide type wheels with a coolant. Milling. Carbide cutters are suggested. Feed and speeds should follow recommendations for Gray Cast Iron.

Jul 08, 2004 Cutting of Titanium Alloys Titanium alloys can be cut cold by conventional power hacksaws, circular saws, band saws, shears, nibblers or water jet. Hot cutting using oxy-acetylene torch, plasma or laser will result in oxidation of the adjacent metal and for many applications this will require to be removed by grinding or machining before further processing is undertaken.
With higher alloy content and hardness, the machinability of titanium alloys by traditional chip-making methods generally decreases. This is true of most other metals. At a hardness level over 38 RC 350 BHN increased difficulty in operations such as drilling tapping, milling, and broaching can be expected.
The high alloy content of tool steel means that such steel are often more difficult to grind than conventional structural steel. In order to achieve successful results when grinding tool steel, it is necessary to choose the grinding wheel with care. In turn, choosing the right grinding wheel and grinding data requires an understanding of how a
