2. Rotary table - Wikipedia

   en.wikipedia.org/wiki/Rotary_table

   A rotary table is a precision work positioning device used in metalworking. It enables the operator to drill or cut work at exact intervals around a fixed (usually horizontal or vertical) axis. Some rotary tables allow the use of index plates for indexing operations, and some can also be fitted with dividing plates that enable regular work ...

   Rotary table (drilling rig) In this simple diagram of a drilling rig, #20 (in blue) is the rotary table. The kelly drive (#19) is inserted through the center of the rotary table and kelly bushings, and has free vertical (up & down) movement to allow downward force to be applied to the drill string, while the rotary table rotates it.

5. Broaching (metalworking) - Wikipedia

   en.wikipedia.org/wiki/Broaching_(metalworking)

   Broaching is a machining process that uses a toothed tool, called a broach, to remove material. There are two main types of broaching: linear and rotary. In linear broaching, which is the more common process, the broach is run linearly against a surface of the workpiece to produce the cut. Linear broaches are used in a broaching machine, which ...

   Jig borer. The jig borer is a type of machine tool invented at the end of World War I to enable the quick and precise location of hole centers. It was invented independently in Switzerland and the United States. [1] It resembles a specialized kind of milling machine that provides tool and die makers with a higher degree of positioning precision ...

8. Rotary transfer machine - Wikipedia

   en.wikipedia.org/wiki/Rotary_transfer_machine

   A rotary transfer machine is a machine tool, typically for metal working by machining, comprising a large indexing table with machining stations surrounding the table. Such rotary transfer machines are used for producing a large number of parts in fairly short cycle times.

9. Indexing head - Wikipedia

   Indexing head. Indexing head and tailstock set up on a milling machine's table. An indexing head, also known as a dividing head or spiral head, [1] is a specialized tool that allows a workpiece to be circularly indexed; that is, easily and precisely rotated to preset angles or circular divisions. Indexing heads are usually used on the tables of ...
