Spindle Head

Spindles are rotating shafts used for holding a tool or cutting a workpiece. In any machining center, to perform any kind of machining tasks, spindles are essential. Spindles are applicable in various applications like drilling, milling, engraving, boring, grinding etc. But the actual performance of the spindles depend on the heads installed or fixed on to them so as to perform the different tasks. Spindle heads are designed in a way so as to maximize the efficiency of the spindle.

 

What are spindle heads?
Spindle heads are specialized tool holders that are fixed on machine tool spindles. Most spindle heads are multi rather than single. Multi spindle heads help in performing simultaneous machining operations. Most spindle heads cannot be shared, except in the case of identical-hole patterns in a family of parts. Spindle heads are designed for use with most drilling machinery and can easily enhance drilling operations by simultaneously drilling, countersinking, reaming or tapping two or more holes in a single operation. They are considered to be the most versatile method to drill and/or tap close spaced holes.
