Indexing Attachment
Machining operations often require cutting features in a radial pattern rather than in a straight line. Common examples include gear teeth, splines, and flats on nuts. The Sherline Indexing Attachment provides an economical and highly accurate way to rotate and position a workpiece for machining these types of features.
Features & Benefits
Included Components
Spindle Compatibility
The indexing head uses a spindle with a #1 Morse taper and 3/4"-16 male thread, identical to Sherline lathe and mill spindles. This allows the use of common Sherline accessories, including:
Precision Indexing Capability
For positions beyond the standard 5° detents, the rack gear converts spindle rotation into measurable linear travel. This movement can be measured with the depth rod of a Vernier caliper, allowing extremely accurate indexing to an infinite number of positions.
Mounting & Use
The indexing attachment can be mounted directly to the table of a Sherline milling machine. The indexing head may also be used independently in a horizontal position similar to a rotary table.
Note: Use on a Sherline lathe with the vertical milling column is not recommended. However, it may be possible with shims installed to raise the unit high enough to clear the crosslide handwheel.
