It’s no surprise that a common application of centerless grinding is for manufacturing engine and
transmission components such as needle rollers, injector plungers, camsh-afts and input shafts.
These precision components are manufactured to tight tolerances and must be produced at high
levels to fuel the demand for millions of new vehicles that are sold every year. This high demand
for precision components gives the centerless gri-nding machine a key role in keeping the wheels
turning in our society.
But, centerless grinding is not limited to automotive applications. Centerless grinding is also used
in the manufacture of components for several other industries, such as information technology,
industrial, medical, agricultural and durables, such as appliances. Thus, centerless grinding applications
can be found throughout our society, such as in the computers we use, in our appliances, in the
equipment that harvests our food and so forth.
The centerless grinding machine utilizes three main components to accomplish its work, a
grinding wheel, a regulating wheel and a work blade. Over the years, this general grinding
concept hasremained the same. The regulating wheel determines the rotational speed and
linear travel of the part in through feed applications. For infeed applications, the regulating
wheel controls the rotational speed of the part and pushes the part against the stop. The
work blade supportsthe part as the grinding wheel removes part material. While the general
concept has remained the same for the last 40 to 50 years, technological advancements along
the way have improved the centerless grinding process. Amongthe benefits of these improve-
ments in centerless grinding technology are greater ease of operation and maintenance, increa-
sed productivity and the capability of holding extremely tight tolerances.
