ying grinding times, number of grinding additive tab-lets as well as the pressing parameters are entered and stored by the system. In case of a problem the operator receives clear information to locate the fault quickly – thus ensuring a quick return to automatic operation. The automatic milling and pressing system is designed
Grinding at shallow angles can prolong the wheel's lifespan, but it also often compromises the cut-rate. On harder materials, shallow grinding angles may also increase unwanted vibration and chatter. TYPE 28. Type 28 grinding wheels, also known as saucer wheels, have similarly depressed centers and are optimized for low grinding angles.
3. The outer mechanics of the eccentric vibration mill Fig. 3 shows the vibration-mechanical model of the eccentric vibration mill. While, due to the arrangement of the equalizing masses, the grinding-tube axis coincides with the mass centre S of the eccentric vibration mill, the exciter axis is located at a horizontal distance a from S.

For energy-efficient comminution, the grinding-media and the extent of griding-media filling are decisive, in addition to the speed. Here, the following predefinitions are time-tested as standard figures: Grinding-media filling of approx. 35 % and filling with material to be ground of approx. 25 % of the empty grinding-drum volume. Function
Grinding – Ex. 1-1 • You are grinding a steel, which has a specific grinding energy (u) of 35 W-s/mm3. • The grinding wheel rotates at 3600 rpm, has a diameter (D) of 150 mm, thickness (b) of 25 mm, and (c) 5 grains per mm2. The motor has a power of 2 kW. • The work piece moves (v) at 1.5 m/min. The chip thickness ratio (r) is 10.

Grinding low-alloy tool steels seldom presents any difficulties. When grinding high-alloy tool and high-speed steels with high carbide content, however, problems can easily occur. For this reason, the grinding parameters must be selected carefully. The higher the wear resistance of a steel, the more difficult it is to grind.
