The hammer mill is the best known and by far the most widely used crushing device employing the impact principle of breaking and grinding stone Thus far we have described machines which do a portion of their work by impact, but the only machine described in which this action plays an important role was the sledging roll type and particularly the Edison roll crusher and in these machines with wear resistant material During operation, 80% of the container is filled with grinding bodies and the starting material Here vibratory motion is obtained by an eccentric shaft that is mounted on a frame inside the mill The rotation of eccentric shaft causes the drum of the vibrating mill to oscillatePowder metallurgy – basics applications Gang milling is a horizontal milling operation that utilises three or more milling cutters grouped together for the milling of a complex surface in one pass As illustrated in figure 18, different type and size of cutters should be selected for achieving the desire profile on the workpiece Figure 18 Gang Milling 64 Straddle MillingContents Points of Operation hazards and controls • The point of operation is the place where the work is actually performed on the materials • In the example to the right, the point of operation is where the saw cuts into the wood • This area presents a hazard for the employee using the saw Points of operation need to be guarded 32Hand amp; power tools ppt 2 SlideShare machining operation that requires a coolant (2) Knee The knee is the casting that supports the table and the saddle The feed change gearing is enclosed within the knee It is supported and can be adjusted by the elevating screw The knee is fastened to the column by dovetail ways The lever can be raised or lowered either by hand or power feedMILLING MACHINE OPERATIONS HNSA
