About Rotary Tables

Rotary Table provides rotational force to a drill string for carrying out the process of drilling a borehole. These tables find heavy usage in the metalworking industry. A table is made of solid base that is clamped to a fixture.

In simpler words, rotary indexers are kind of discs that freely rotate or are rotated by using a hand crank (worm). You can mount these tables in vertical, horizontal or even inverted styles. When the table is fixed horizontally, it is in a horizontal, upright and flat position. In case of vertical mounting, the surface of table runs up or down; while, in horizontal angle, it is upside down.

Rotary tables are used in applications like assembling, machining and automation. These tables are also used in equipment positioning. While buying a rotary table, there are a few things to be considered:

Worktable Diameter

A worktable diameter is the surface area of the rotary actuators.

Through-Hole Diameter

The breadth of the hole at the center of the workstation is its through-hole diameter.

Radial Load

Always pay attention to the maximum load the table will be able to bear during concentric operation.


Check out the maximum rotation speed of the device.

Indexing Increment

It is the smallest angle set on the table.

The mount of the rotary table decides the location of the drive on it. User can place the drive behind, below, on top and even on the side of the table. When you mount the drive horizontally, it’s located over the surface. In case the table is horizontally mounted, a side-mounted drive is place on the side of the surface.

You can drive the rotary tables pneumatically, electrically, manually and even electrically. In case it is being driven manually, make sure the table is loosened and turned manually with crank.
