Horizontal Grinders vs Tub Grinders Rotochopper

Apr 19, 2019Horizontal grinders, however, provide better control over feeding rates because feedstock is delivered into the grinding chamber at a steady speed. The powerfeed drum (feed roll) of a horizontal grinder digs into feed material to provide a level of feed rate control much greater than a tub grinder can achieve. If raw material feeds too quickly

Cutting Tool Applications, Chapter 17 Grinding Methods

In creep-feed grinding, developed in the late 1950s, the wheel depth of cut is as much as 0.25 in. and the workpiece speed is low. Its overall competitive position with other material-removal processes indicates that creep-feed grinding can be economical for specific applications, such as in grinding shaped punches, twist-drill flutes, and various complex super alloy parts.
