DIRECT DRIVE ROTARY TABLE

Direct Drive Rotary Table is a kind of rotary table used to the continuous operation which is several times more agile and accurate than conventional face gear or rack and pinion rotary tables.

Thanks to the use of specific bearings, Direct Drive Rotary Table has got to highly rigid and stable characteristics with a low runout of less than 0.015 mm in a very compact form factor.

A strong high torque motor used as the heart of the Direct Drive Rotary Table to make it rapid, stiff and powerful which is being monitored by a high-resolution encoder to reach the real flexibility with high accuracy.

From among other advantages of these Direct Drive Rotary Tables, we can refer to the short time of indexing, their repeatability, their free choice of indexing positions, and their tolerability of extremely high radial and axial torques during rotation and stopping.

Systems based on Direct Drive Rotary Table will surely be free of any defects for a long time, and will not require any repairs. Based on the application requirements, this product can be equipped with internal and/or external clamps.

Direct Drive Rotary Table Features

High torque output direct drive with a compact design
