A rotary table is a mechanical device used in machining to precisely rotate the workpiece on a fixed axis, allowing for accurate angular adjustments during operations such as milling, drilling, and turning. It consists of a table that rotates about its central axis, which can be manually or motor-driven, depending on the model. The advantages of a rotary table include the ability to perform complex multi-axis machining, improve precision, and reduce cycle time in operations. It is commonly used in CNC machines, providing versatility in manufacturing gears, cams, and other geometrically complex parts. The rotary table offers enhanced control over part positioning and ensures consistency and repeatability, making it indispensable in high-precision industries like aerospace, automotive, and mold-making.
