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 friction welding is widely implemented across the manufacturing sector and has been used for numerous applications, [17] [18] [19] including: Parts in gas turbine such as: turbine shafts, turbine discs, compressor drums, [20]
Some applications and patents connected with friction welding dates back to the turn of the 20th century, [3] and rotary friction welding is the oldest of the methods. [4] W. Richter patented the method of linear friction welding (LFW) process in 1924 [ 5 ] in England and 1929 [ 5 ] in the Weimar Republic .
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. [1] [2] [3]
The rotary bushings are located at the center of the rotary table. These can generally be removed in two separate pieces to facilitate large items, e.g. drill bits, to pass through the rotary table. The large gap in the center of the rotary bushings is referred to as the "bowl" due to its appearance.
