Index Head:
An index head, also known as an indexing head, is a device or component used in machinery, particularly in metalworking, milling, and drilling machines, to rotate or position a workpiece. Its purpose is to provide precise and accurate indexing, which involves dividing a circle or angular measurement into equal parts for efficient and repeated machining operations.
Typically, an index head consists of a spindle or chuck that holds the workpiece securely in place and a locking mechanism to prevent movement during machining. It is mounted on a machine's table or spindle and can be adjusted or tilted to the desired angle for specific machining tasks.
Index heads often feature a graduated dial or index plate with markings or divisions that allow for precise positioning and rotation. This enables the machinist to accurately set incremental angles, such as 90 degrees or any other division or angle required for producing intricate or complex shapes, slots, flutes, or gears on the workpiece.
The use of an index head in machining operations enhances productivity, as it allows for quick and easy repositioning of the workpiece without having to reconfigure the machine or change tools. It provides the means to perform operations such as grooving, cutting, grinding, or drilling evenly spaced features on the workpiece, thereby ensuring accuracy and efficiency in the manufacturing process.

Etymology of INDEX HEAD

The term "head" in this context refers to the top or leading part of something, or the part that comes first or indicates the rest. In the case of an index, the "index head" refers to the section or portion at the beginning of a book or document that contains a list of topics or keywords referenced in that text.
