In cylindrical grinding operation, the work is mounted between two centres and is rotated. A grinding wheel is mounted on a spindle and revolves at much higher r.p.m. than the work. The work centres are mounted on a table which can traverse at various feeds so that the entire length of the work passes to and fro in front of the wheel.

Internal cylindrical grinding operates somewhat like a boring operation. The work-piece is usually held in a chuck and rotated to provide surface speeds of 20 to 60 m/min (75 to 200 ft/min) [16].Wheel surface speeds similar to external cylindrical grinding are used. The wheel is fed in eitheroftwo ways: traverse feed, Figure 25.9(b), orplunge feed. . Obviously, the wheel diameter in internal ...

Tool Grinding Mills cutters, reams, and single point tools require sophisticated grinding provided by a tool grinder that differs from a universal cylindrical center-type grinder by: 1. The headstock is not motorized. 2. The headstock can be swiveled about a horizontal as well as a vertical axis. 3.
Grinding operations: Cylindrical grinding 1. External cylindrical grinding (also called center-type grinding to distinguish it from centerless grinding) is performed much like a turning operation. 2. The cylindrical workpiece is rotated between centers to provide a surface speed of generally 18 to 30 m/min, and the grinding wheel rotating generally at 1200 to 2000 m/min, is engaged to perform ...

Can you guys recommend an appropriate work piece SFM for grinding carbide, either cylindrical or surface? The Norton catalog provides optimum wheel SFM ranges, but nothing about the work piece. Neither does Machinery Handbook. My machinery isn't particularly rigid or powerful, a K.O. Lee 6062H and a Cincinnati Monoset. I'm grinding dry.
