Rotating Table for Angle Work {ROTATION TABLE}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a rotary table for western-style working, and more particularly to a rotary table for a workpiece, which is configured to support a workpiece while wristwatching and to be easily rotated as needed.

History of mankind's use of letters is estimated to be about 6,000 years. The first of the artifacts discovered so far is the Chinese Era of the Era. However, dating back to the roots of the western part of the prehistoric age, the culture of the cuddling began already (Korean Society of the West, 2004).

In this era, before letters were developed, the objects to be engraved were mainly paintings or symbols representing life and magical act, which developed and led to the origin of the characters. At this time, most of the materials of the cuddly crust were stone. Typical examples of the cuddly material are the monumental petroglyphs found at Daegok-ri, Eonyang-myeon, Ulju-gun, Gyeongsangnam- In this study, it was confirmed that the embossing and embossing techniques were used at the same time. Since then, it has roamed the tools used in religious rituals, such as the bronze bellies of the northeastern and agricultural munitions, through the Bronze Age and the Iron Age. Since then, in the Three Kingdoms era and Unified Silla period, Buddhist culture has been influenced by the influx of Buddhist culture. As the use of letters gradually became more and more common, it changed into a form that combines with letters and is mainly used to engrave inscriptions on stone, Respectively. One of the typical western works of this era is the Gwanggaeto to Queen and the Namhansanseong tomb.

Looking at the western part of the Goryeo Dynasty, it can be seen that the culture of cuddling that extended to the publication of the Buddhist scriptures and literary works as well as the previous Mt. The representative works of the era in this era are the Haein Temple, Korea University, Changgyeongpan, which is registered as a World Heritage Site.

The Buddhist culture related to Buddhism has declined due to the monotheism of the Buddhist monks who passed on to the Chosun Dynasty. The culture of cuddly gourmets for the production of lyric plates, palaces, oriental religions, Typical examples of this era are the five editions (Gyeongbokgung, Changgyeonggung, Deoksugung, Gyeonghui, Changdeokgung).

In recent years, the culture of cuddling has been developed mainly for the publishing of literature by the influence of the inventor of metal type letterpress. Typical examples are woodblocks of Hunminjeongeum woodblock, Daedongjaeji, and repairing evangelism.

In modern times, however, various materials such as wood, stone, iron, polycoat, terracotta, clay, gypsum and woodrock have begun to be used in the cuneiform material used in the culture of cuddling. This is because of the diversity of works and the purpose of pursuing the aesthetic beauty of distinctive swords. However, it is difficult to purchase wood materials that are easy to produce, and it is also difficult to obtain especially wide-width materials.

In addition, there is a problem that it takes a long time because the work is difficult because the pieces are formed at various angles to produce one work.

Accordingly, the operator moves around the table on which the object to be wobbled is placed, and performs a wobbling operation at a desired position. This causes a problem in that the work inconvenience and the work time of the worker are increased, . Therefore, it is required to develop a device capable of performing a wedge operation by fixing an object to be wedged at a desired position in a fixed position by an operator.
