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 positioning at divisions for which indexing plates are not available. A rotary fixture used in this fashion is more appropriately called a dividing head (indexing head).

The table shown is a manually operated type. Powered tables under the control of CNC machines are now available, and provide a fourth axis to CNC milling machines. Rotary tables are made with a solid base, which has provision for clamping onto another table or fixture. The actual table is a precision-machined disc to which the work piece is clamped (T slots are generally provided for this purpose). This disc can rotate freely, for indexing, or under the control of a worm (handwheel), with the worm wheel portion being made part of the actual table. High precision tables are driven by backlash compensating duplex worms.

The ratio between worm and table is generally 40:1, 72:1 or 90:1 but may be any ratio that can be easily divided exactly into 360°. This is for ease of use when indexing plates are available. A graduated dial and, often, a vernier scale enable the operator to position the table, and thus the work affixed to it with great accuracy.

Rotary tables are most commonly mounted "flat", with the table rotating around a vertical axis, in the same plane as the cutter of a vertical milling machine. An alternate setup is to mount the rotary table on its end (or mount it "flat" on a 90° angle plate), so that it rotates about a horizontal axis. In this configuration a tailstock can also be used, thus holding the workpiece "between centers."

With the table mounted on a secondary table, the workpiece is accurately centered on the rotary table"s axis, which in turn is centered on the cutting tool"s axis. All three axes are thus coaxial. From this point, the secondary table can be offset in either the X or Y direction to set the cutter the desired distance from the workpiece"s center. This allows concentric machining operations on the workpiece. Placing the workpiece eccentrically a set distance from the center permits more complex curves to be cut. As with other setups on a vertical mill, the milling operation can be either drilling a series of concentric, and possibly equidistant holes, or face or end milling either circular or semicircular shapes and contours.

* With the addition of a compound table on top of the rotary table, the user can move the center of rotation to anywhere on the part being cut. This enables an arc to be cut at any place on the part.

Additionally, if converted to stepper motor operation, with a CNC milling machine and a tailstock, a rotary table allows many parts to be made on a mill that otherwise would require a lathe.

IP rated rotary tables provide more possibilities for humidity and dusty environment in actual working conditions, like CNC drilling work, CNC grinding work, laser marking and laser cutting work, etc.

High precision and excellent IP rated performance makes the high precision and accuracy work possible, such as diamond cutting rotary task, phone production and inspection rotary task, etc.

After adding four-axis or five axis rotary table on the machine tool, multi axis machining can be realized, which can improve the machining efficiency and yield. With the improvement of manufacturing automation in China, the demand for rotary table increases significantly.

Now, I will introduce the situation of several rotary table brands in China. We will divide them into four categories: Europe andAmerica, Japan, Taiwan and Chinese brands.

Taiwan: TJR, Detron and GSA are the main brands, as well as DEX, Autocam and HW. These rotary tables are not only configured on Chinese brand machine tools, but also sold to end customers. Their precision is not high and their service life is not long, but they can meet the requirements when machining parts with low precision. Some users will consider these brands when their budget is limited. Among these brands, TJR has the best sales volume, with an annual sales volume of more than 10000 sets, because they have the most complete distribution network, complete models and cheap prices.Most importantl

China: there are many locally four-axis brands in China, such as Gutia,Silvercnc, Blue tech, CP and Deshu. The product quality of these brands is comparable to that of Taiwan. Due to more favorable prices and fast delivery, they have occupied the market of most Taiwan brands. The four axis of Chinese brands mainly adopt roller cam structure or harmonic structure. The wear resistance of roller cam is better than that of worm gear, with long service life and good accuracy retention. The price of harmonic reducer rotary table is low, which is suitable for 3C industry. These two structures meet the needs of the market and have been recognized by customers.

- Using axial/radial bearings, they can allow heavy loads and are suitable for heavy cutting. The runout of axial and surface flatness is decreased, and higher accuracy is acquired.

Although it is recorded that the Han Dynasty (202 BC – AD 220) court eunuch Cai Lun (50 AD – AD 121) invented the pulp papermaking process and established the use of new materials used in making paper, ancient padding and wrapping paper artifacts dating to the 2nd century BC have been found in China, the oldest example of pulp papermaking being a map from Fangmatan, Tianshui;was in widespread use, replacing traditional but more expensive writing mediums such as strips of bamboo rolled into threaded scrolls, strips of silk, wet clay tablets hardened later in a furnace, and wooden tablets.Alxa League, where Han Dynasty troops had deserted their position in AD 110 following a Xiongnu attack.mulberry tree bark, hemp, old linens and fish nets created a pulp that was pounded into paste and stirred with water; a wooden frame sieve with a mat of sewn reeds was then dunked into the mixture, which was then shaken and then dried into sheets of paper that were bleached under the exposure of sunlight; K.S. Tom says this process was gradually improved through leaching, polishing and glazing to produce a smooth, strong paper.

Shen Kuo (1031–1095) of the Song dynasty (960–1279) was the first to describe the process of movable type printing in his Bi Sheng (990–1051).Wang Zhen (fl. 1290–1333) of the Yuan dynasty (1271–1368), who also arranged written characters by rhyme scheme on the surface of round table compartments.Hua Sui (1439–1513) of the Ming dynasty (1368–1644) that the Chinese perfected metal movable type characters, namely bronze.Qing dynasty (1644–1912) scholar Xu Zhiding of Tai"an, Shandong developed vitreous enamel movable type printing in 1718.

Du Shi (d. 38 AD) applied the use of rotating waterwheels to power the bellows of his blast furnace smelting iron, a method which continued in use in China thereafter, as evidenced by subsequent records; it is a significant invention in that iron production yields were increased and it employed all the necessary components for converting rotary motion into reciprocating motion.

Greek philosopher Aristotle (384–322 BC) observed that the spaces between the leaves of trees acted as tiny pinholes which cast the image of a partial solar eclipse onto the ground.Chinese philosopher Mozi (c. 470 BC – c. 391 BC)—founder of Mohism during the establishment of the Hundred Schools of Thought—lived just before the time of Aristotle and it was in his Mojing (perhaps compiled by his disciples) that a pinhole camera was described.Mojing stated that the "collecting place" (pinhole) was an empty hole "like the sun and moon depicted on the imperial flags," where an image could be inverted at an intersecting point which "affects the size of the image."Mojing seems to be in line with the Epicurean theory of light traveling into the eye (and not vice versa like in Pythagoreanism),Mojing states that the reflected light shining forth from an "illuminated person" becomes inverted when passing through the pinhole, i.e. "The bottom part of the man becomes the top part (of the image) and the top part of the man becomes the bottom part (of the image)."Ibn al-Haytham (965–1039) wrote of his experimentation with camera obscura, which was followed by Song dynasty polymath Shen Kuo (1031–1095), the latter who alluded that the Tang Dynasty (618–907) writer Duan Chengshi (died 863)—in his Chinese pagodas.

Zhou Dynasty Chinese text of the Book of Odes) records that King Wen of Zhou was the first to create a pontoon bridge in the 11th century BC. However, the British scientist, sinologist and historian Joseph Needham has pointed out that in all likely scenarios, the temporary pontoon bridge was invented during the 9th or 8th century BC in China, as this part was perhaps a later addition to the book (considering how the book had been edited up until the Han Dynasty, 202 BC–220 AD). Although earlier temporary pontoon bridges had been made in China, the first secure and permanent ones (and linked with iron chains) in China came first during the Qin Dynasty (221 BC–207 BC). The later Song Dynasty (960–1279 AD) Chinese statesman Cao Cheng once wrote a description of the early pontoon bridges in China.Yellow River. There was also the rebellion of Gongsun Shu in 33 AD, where a large pontoon bridge with fortified posts was constructed across the Yangtze River, eventually broken through with ramming ships by official Han troops under Commander Cen Peng. During the late Eastern Han into the Three Kingdoms period, during the Battle of Chibi in 208 AD, the Prime Minister Cao Cao once linked the majority of his fleet together with iron chains, which proved to be a fatal mistake once he was thwarted with a fire attack by Sun Quan"s fleet. The armies of Emperor Taizu of Song had a large pontoon bridge built across the Yangtze River in 974 in order to secure supply lines during the Song Dynasty"s conquest of the Southern Tang.

air conditioning, the Han Dynasty craftsman and mechanical engineer Ding Huan (fl. 180 AD) invented a manually operated rotary fan with seven wheels that measured 3 m (10 ft) in diameter; in the 8th century, during the Tang Dynasty (618–907), the Chinese applied hydraulic power to rotate the fan wheels for air conditioning, while the rotary fan became even more common during the Song Dynasty (960–1279).Georg Agricola (1494–1555).
