| Introduction |
 The singlepass, bore
finishing process was originally developed to improve the bore quality
of cast iron components, such as hydraulic valve bodies. For many years
it was thought that while ideally suited for similar throughbore
applications, its use would be limited. This initial belief has proven
to be unfounded as the singlepass process now has been developed to a
point where almost any application, in almost any type of material is
possible. For example; as well as the many cast iron
application’s that are successfully being finished with this
process, today there is probably an equal amount being done in other
materials. These materials include varieties of hard and soft steel,
aluminum, bronze, brass, ceramics, chrome, as well as multimaterial
assemblies. The singlepass process is also now capable of finishing
most blind bores and well as through.
This paper will explain the basic principles of the singlepass process,
and provide details on some of the latest advancements that have been
made.
- Out performs ordinary stone in
cutting action,finish speed and wear resistence.
- Superior performance with increased
efficiencies perfect for any size operation.
- Low production cost,high precision
and long workpiece life.
- Our honing stones can honed the
bore diameter smallest to 1.5mm(0.6inches)
