Jig grinding is well known as a precision internal machining process for high precision products such as dies and fixtures. Investigation to realize high productivity and high accuracy is performed with different electrodeposited CBN wheels under various grinding conditions. Grinding characteristics such as grinding forces, torque and surface roughness were measured. The main results obtained are as follows. (1) Grinding accuracy improved with an increase in peripheral speed of grinding wheel. (2) Grinding forces and torque decrease with an increase in peripheral speed of wheel but increase with wheel depth of cut and work feed rate. (3) Grinding forces and torque increase with the cumulative stock removal which is caused by the progress of attritional wear of CBN abrasive grains. (4) A clear reduction of grinding forces is caused by quill motion overlapping the main axis and is induced by the decrease in the mean chip volume and/or the mean chip cross-sectional area.
