What is an indexing head?

Indexing head is an attachment used on machines, which allows the workpiece around its own axis in the same steps. This facilitates machining of accurate, equal aspects as square heads or hex profiles. Indexing Attachments of the head are usually mounted on milling machines to carry out flat cuts and can be manually modified or automatically advanced. Most of them are capable of moving 90 ° through their own axis, allowing a good range of cutting options. Indexing heads are usually designed to make it easier to cut the selection of the bean numbers and are often available in sets that cover a wide range of machining requirements. This device ensures the workpiece and allows it to turn it in precise steps to allow cutting individual aspects. Based on a conventional chuck or terminal, the indexing head is also an equipped with an indexing disc, which has several concentric rows on the surface, usually 6, equally spaced holes. Each line has a specific number of holesWith each subsequent line, which has fewer holes towards the center of the disk. The typical numbers of holes range between 15 and 49 with discs generally available in sets that offer a wide range of different aspects.

At the beginning of the cutting, the disc is locked in a place with a spring pin passing through the hole in the appropriate row and to a lockable niche. After the cut is finished, the pin is inserted, the head proceeded with the set number of holes and cutting starts on another aspect. The disk is advanced with the same number of holes with each cycle, allowing cutting accurate, accurate profiles. The indexing head can introduce the workpiece parallel to the cutting tool or be rotated by 90 ° for further flexibility in the section geometer.

, also known as a dividing head, the indexing head is either manually or fully automated. Hand progress is achieved by a handle or handle that turns the lead screw and turn the disk checkin a vary manner. Automated progress usually occurs only on large industrial machines and depends on a separate spindle to turn the disc. These systems are generally part of a fully automated computer numeric control (CNC) of milling machines that have cutting cycles completely controlled by computer.
