Understanding NC Rotary Tables: Types, Features, and Options
#

NC rotary tables are essential components in modern machining, enabling precise positioning and multi-axis movement for complex workpieces. At TOPSDISK, we offer a diverse selection of 4th-axis and 5th-axis rotary tables, also known as dual-axis NC rotary tables, designed to meet a variety of manufacturing needs. Below, we detail the main categories, features, and product options available.

Classification of Rotary Tables
#

Our rotary tables can be categorized based on installation method, transmission mechanism, clamping system, and size.

Installation Methods
#

Vertical Rotary Table: Installed upright, this table rotates on a horizontal plane and can be lifted vertically. This configuration keeps the workpiece stable and allows for flexible height adjustments, enhancing machining efficiency.
Horizontal Rotary Table: Designed for rotation on a horizontal plane, this type is ideal for positioning workpieces at various angles, making it suitable for multi-angle or multi-face processing machines.

Transmission Methods
#

Direct Drive Rotary Table: Utilizes direct drive technology, eliminating reducers, gearboxes, and pulleys. This results in faster acceleration/deceleration, reduced transmission error, and higher motion stability. Direct drive tables are ideal for high-precision applications but are more costly to manufacture.
Worm Gear Rotary Table: Employs a worm wheel and shaft mechanism, providing high torque and self-locking capability for stable machining. While robust, this type may have some transmission gap, making it less precise and slower than direct drive models.

Clamping Methods
#

Pneumatic Rotary Table: Powered by compressed air, these tables are cost-effective and safe, offering quick start/stop for high-speed movement. Best suited for small workpieces due to limited load capacity.
Hydraulic Rotary Table: Designed for heavy-duty applications, hydraulic systems handle large loads and allow for adjustable speed and direction. They require more complex design and technical support.
