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]
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.
The turntable bridge (the part of the turntable that included the tracks and that swivelled to turn the equipment) could span from 6 to 120 feet (1.8 to 36.6 m), depending on the railway's needs. Larger turntables were installed in maintenance facilities for longer locomotives, while short line and narrow gauge railways typically used smaller ...
SME was founded by Alastair Robertson-Aikman [2] in 1946 under the title The Scale Model Equipment Company Limited to manufacture scale models and detail parts for the model engineering trade. [ 3 ] [ 4 ] It was During the 1950s the company moved away from model making to precision engineering, principally parts for aircraft instruments and ...
