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. With horizontal mounting, the table surface is in a flat, upright, horizontal position. With vertical mounting, rotary tables are mounted so the rotary table surface runs up and down. In inverted mounting, the rotary table can be upside down in the horizontal position.
A rotary table is a mechanical device on a drilling rig that provides clockwise (as viewed from above) rotational force to the drill string to facilitate the process of drilling a borehole. Rotary speed is the number of times the rotary table makes one full revolution in one minute (rpm). Rotary tables consist of a round and driven table top made of laminate, stainless steel or another function-specific material. The base frame is built from Series 40 profiles as standard and equipped with height-adjustable levelling feet. Cover panels made from sheet metal or polycarbonate can be easily attached.
A rotary table is the revolving plate on the rig’s drill floor that turns the drill string in a clockwise direction. The rotary table surrounds the four or six-sided kelly bushing and kelly drive to which the drill string is attached, transferring the power from the rig’s drive system to the drill string and bit.
