4th Axis / Indexer Fixturing

Abbott’s round base tooling columns are designed for use with an indexer or 4th axis rotary table in vertical machining environments. They can be purchased as raw castings or with any level of machining desired.

Standard machined versions include holes in the base for mounting to the indexer table and a standard 60° tailstock center hole, for use with a live or dead center. For heavy duty applications where a shaft style tail support is used, adaptor plates, locating plugs and other custom components can be manufactured to provide a complete turnkey workholding solution.

Additionally, Abbott can design assemblies that integrate our columns with vises, clamps and workholding products from other manufacturers, providing a seamlessly integrated assembly.
