Selecting The Right Rotary Table For Your Business

7 March 2023 by Felix Mason

A rotary table is an essential tool for any precision machining business. It positions a workpiece at precise angles, allowing for accurate and efficient machining. However, choosing the right rotary table requires knowing what to look for when evaluating potential rotary tables.

The Accuracy Of The Rotary Table

The accuracy of a rotary table is a crucial factor to consider when selecting a new one. The accuracy of a rotary table is typically measured in arc seconds, which refers to the amount of deviation that can occur when the table is rotated. The smaller the arc seconds, the more accurate the rotary table.

Furthermore, it is crucial to consider the application for which you will be using the rotary table. Some applications require higher levels of accuracy than others. Therefore, it is essential to match the rotary table's accuracy to your specific application's needs.

The Rotary Table's Repeatability

Repeatability refers to the ability of the rotary table to return to a previously set position with high accuracy. This is particularly important when performing multi-step machining operations.

Achieving high repeatability requires the rotary table to have a precise indexing system. Additionally, the rotary table must be constructed with high-quality materials that can withstand the forces of machining without deforming or wearing. Additionally, some manufacturers offer calibration services to ensure that your rotary table is working at its maximum repeatability.

The Control Method Used For The Table

Another critical factor to consider is the control method used for the rotary table. Rotary tables can be manually or computer-controlled. Manual rotary tables are typically less expensive and easier to operate, but they require more skill and experience to achieve high accuracy and repeatability.

Computer-controlled rotary tables are more expensive but offer greater accuracy, repeatability, and flexibility. They can be programmed to perform complex machining operations automatically and integrate into a more complex manufacturing system. A thorough assessment of your business needs will have to be conducted to determine the option that will best suit them.

The Orientation Of The Rotary Table

The orientation of the rotary table is another critical factor to consider when selecting a new one. Rotary tables can be horizontal or vertical, with each orientation offering different advantages and limitations.

Horizontal rotary tables are typically used for milling operations and are best suited for machining workpieces with a flat surface. Vertical rotary tables are typically used for drilling and grinding operations and are best suited for machining workpieces with cylindrical or irregular shapes.
