what is effective volume of ball mill

  • Defintions of Light Oil Medium Oil Heavy Oil

    The oil can be so heavy in the middle that you have to throw it slow and use a strong ball to get the ball to hook after it comes off the end of the pattern BUT the outsides (say 1-5 on both sides) can be so dry that if you use a breakpoint in that are you d need the mildest of resinss to play there unless you had very high ball speed.

  • Selecting a Carbide End Mill for Aluminum Applications

    Mar 01 2007 · A high helix angle generally around 45 degrees is also desirable.The helix helps move chips up and out of the cutting zone and also generates an excellent surface finish. The angle also helps soften the impact at entrance of cut resulting in a smoother quieter cut (see Figure 1).. For aluminum milling a two- or three-flute end mill works best because this allows for larger flute areas.

    Commonly used end mills have four or six flutes. In titanium this might be too few. The more effective number of flutes could be ten or more (see Figure 2). Increasing the number of flutes compensates for the need for a low feed per tooth. The close flute spacing of a 10-flute tool is too tight for chip clearance in many applications.
