Purpose of the CNC Rotary Indexer Riser Plate
When using the CNC Rotary Indexer on a Sherline mill, a riser plate is not necessary. However, because the bottom of the stepper motor mount extends slightly below the bottom surface of the rotary table, when mounting the table on a full-size mill or large, flat fixture, it will be necessary to raise the table slightly to provide clearance for the mount and stepper motor. In other words the stepper motor mount hits the table and keeps the bottom of the rotary indexer from mounting flat. For this reason, the riser plate was developed to allow flat mounting of the indexer to any surface.
This plate is pre-drilled to allow mounting of the CNC rotary table and has four mounting holes to attach it to a Sherline mill table or to any fixture. Plans showing exact hole centers are included on page 20 of the instructions for the CNC Rotary Indexer for those needing to drill a matching mounting hole pattern to attach the riser plate to their fixture. Since it is made from cast material, it is free of internal stresses and can be drilled with additional mounting holes without fear of warping. Included are three screws for attaching the table to the plate and four screws for attaching the plate to your fixture. Also included are four T-nuts should you wish to mount it to a Sherline mill table or industrial slide with T-slots sized for Sherline T-nuts.
Always wear safety glasses when operating machine tools.
