Advancements in Single-Pass Bore Finishing

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.
