2 The selection of an appropriate drill point angle for your bit should be informed by questions about your application. Yesa hole is a hole is a holebut what is the purpose of the hole what type of metal are you cutting into and what are the specifications for the finished hole In addition to the drill point angle factors that can affect successful drilling include
In general the Tortoise-Hare slider provides a tradeoff between quality of finish and how fast it removes material when roughing. Use a Finish Pass With a Light Cut. Keep a low cut width or cut depth if youre talking the floor of a pocket or surfacing with a Face Mill and do a separate finish pass
2013-4-2The instant center of rotation is the contact point between the wheel and the ground which is distance D2 from the center of the axle. The condition for rolling is that the moment about the instant center FD2 must be greater than the moment due to friction between the axles and the wheels that resists roll-ing which is Mgd2. Hence the

2012-1-30Hope Im posting in the correct area. I would like to know what the advantages of wet grinding compared to dry grinding are if any. Would one expect wet ground material to exhibit different leaching characteristics from dry ground materials even when particle sie distributions are identical Im dealing with uranium ores in a lab scale ball mill Bond Ball Mill
2017-2-16If you want to grind the wet materials in a dry grinding mill the materials must be dried before we turn on the barite grinding mill so that the water content must be less than 1. Second the granularity of materials because there are some difference between barite grinding mill and crusher so the feed sie of the materials could also affect the finish product
