What is the difference between a CNC indexing rotary table and a standard rotary table?

A standard rotary table rotates continuously without preset stops. An indexing rotary table is designed to rotate to precise preset angles and hold position while the cutting tool works. CNC indexing tables add computer numerical control to that process, allowing the operator to program the indexing sequence rather than positioning manually.

What is the difference between a wormgear and a facegear indexing table?

Wormgear tables are the most common and offer flexibility across a wide range of indexing applications with 1-degree or 5-degree increment options. Facegear tables sacrifice that flexibility for extreme rigidity — they're the right choice for dedicated heavy cutting applications where rigidity matters more than versatility.

What does "dual lead worm gear" mean and why does it matter?

A dual lead worm gear is a one-piece wormshaft design that eliminates backlash through axial adjustment. The alternative — a split-type worm gear — uses two pieces that can interrupt the line of contact and introduce friction over time. TJR's dual lead worm gear design produces more accurate indexing and a longer wear life.

Can I use a CNC indexing rotary table on my existing 3-axis machining center?

Yes. A CNC indexing rotary table adds a 4th or 5th axis to an existing 3-axis machining center, enabling multi-face machining without re-clamping the workpiece. TJR tables are compatible with a wide range of machining centers and come with customized faceplates.

What industries use CNC indexing rotary tables?

Aerospace, defense, medical, automotive, construction, food and beverage, and printing are among the most common. Any application requiring precise angular positioning, bolt hole patterns, gear cutting, or multi-face machining is a candidate.
