Optimizing feed rates and speeds: 1. Start off using an RPM derived for the chip load for the material being cut (see charts). 2. Increase the cutting speed (feed rate) until the quality of the part's finish starts to decrease or the part is starting to move from hold downs. Then decrease speed by 10%.

Controls for Grinding Circuit: Feed Rate: Increase from too low. Coarser grind, more circulating load. Effect on classifier overflow depends on fineness of ore feed and amount of increase in feed rate. Decrease from too high. Finer grind, less circulating load. Probably more fine sand in classifier overflow. Ball Mill feed water: Increase

THREAD GRINDING-Produce very accurate threads on hardened materials-Three basic methods are used. 1. Center type grinding with axis feed: (Work spins slower) similar to cutting thread in the lathe. difference a shaped grinding wheel is used instead of the point cutting tool. (even multiple shaped grinding wheel can be used ).

Thread grinding is employed for precision tool and gage work and also in producing certain classes of threaded parts.. Thread grinding may be utilized 1) because of the accuracy and finish obtained; 2) hardness of material to be threaded; and 3) economy in grinding certain classes of screw threads when using modern machines, wheels, and thread-grinding oils.
