Ramping Up To High Speed Machining | MakinoTraduire cette page

Much high speed machining is done on conventional machining centers. It's more about how you cut than what you cut with. If you need higher speed performance from your existing machines, here are some things you can do. The high speed machining question for many shops is not whether to get started but how to get started- without blindly investing in very expensive equipment and .

Impact Crusher Working PrincipleTraduire cette page

Impact crushing can be of two variations: gravity and dynamic. An example of gravity impact would be dropping a rock onto a steel plate (similar to what goes on into an Autogenous Mill). Dynamic impact could be described as material dropping into a rapidly turning rotor where it receives a smashing blow from a hammer or impeller. Attrition crushing is the reduction of materials by rubbing ...

This feature uses centrifugal force to control the blade angle when the rotation speed exceeds the rated speed. 1.3.3 A good vertical axis wind mill has to remain stable when it is spinning it. If not, the turbine will "shake its head" when the rotor is turning. That will reduce the turbine's life and cause other problems such as noise and mechanical wear. So the best solution is to use ...
