Rotary indexing tables can be powered by __________ drives.

Rotary indexing tables can be powered by __________ drives.

• A. Servo
• B. Pneumatic
• C. Hydraulic
• D. All of the above

Answer: (D)

Rotary indexing tables are designed to rotate to specific angular positions with repeatable accuracy, and that motion can be supplied by different drive principles. A servo drive provides precise, programmable positioning with feedback, making it ideal for high-precision indexing at varying speeds. Pneumatic drives use compressed air, offering fast, simple, rugged operation that’s cost-effective for light to moderate loads, though precision is typically lower due to air compressibility. Hydraulic drives deliver high torque and smooth motion, well-suited for heavy loads and demanding torque at controlled speeds. Because these tables can be configured to meet different requirements—speed, torque, accuracy, and cost—they can be powered by all of the above.
