It has been already proved that hard turning is capable technology in cutting of hardened steels however, there are few results regarding to bore manufacturing. The replace ability of hard turning against grinding must be defined in high precision bores when the workpiece has different geometry (e.g. bore diameter, length to diameter ratio). As tolerances given for a workpiece are getting stricter, the transition range between hard turning and grinding must be determined.

however, there are few results regarding to bore
manufacturing. The replace ability of hard
turning against grinding must be defined in high
precision bores when the workpiece has different
geometry (e.g. bore diameter, length to diameter
ratio). As tolerances given for a
workpiece are getting stricter, the transition range
between hard turning and grinding must be
determined. In some cases, it can be also worthy to
utilize the advantages of these two processes to
create a powerful combined technology. A set of
rules was developed to assist the selection of
proper process at process planning.
The research work focussed on manufacturing of high
precision bores, like gears and injection
nozzles in the field of the automotive
industry. The aim of this
work was to select the proper process and process
conditions in manufacturing high precision bores.
The limit of hard turning was studied, and the
transition range between hard turning and grinding
was defined.
