Cylindrical Grinding - Fine MetalWorking

Cylindrical Grinding is a process where you use a grinding wheel rotating in a horizontal axis to cut or grind a cylindrical work-piece mounted on a chuck or between centers rotating in an axis parallel to the grinding wheel axis, in the same plane. Abrasive particles on the grinding wheel do the cutting of material.

What is Cylindrical Grinding - Steps in Cylindrical Grinding

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.

GRINDING FOR TOOLMAKING

Grinding stresses can be reduced by repeated tempering after grinding. In this case, the tempering temperature should be about 30°C lower than the last tempering temperature in order to prevent loss of workpiece hardness. Another way to reduce grinding stresses is to peen the ground parts (see Figure 5.)

Finite element modelling of temperature in cylindrical ...

In grinding, the temperature management is crucial to en- sure part quality [9]. High temperature in the workpiece dur- ing grinding induces tensile residual stresses, which affects the fatigue-life of the workpiece [10]. Residual stresses are typically controlled offline using non-destructive methods like Barkhausen noise [5].
