DIRECT DRIVE INDEXING TABLE

Direct Drive Indexing Table is a kind of rotary table used for indexing operations which is very fast and accurate than conventional gear type indexing tables.

A very high torque motor used to drive the Direct Drive Indexing Table to make it more rapid and stiff. The table is equipped with a high-resolution encoder to reach a high accuracy in positioning and assuring repeatability.

Direct Drive Indexing Table is highly rigid with stable characteristics and low runout of less than 0.015 mm in a very compact form factor.

Other advantages of these Direct Drive Indexing Tables are short time indexing, repeatability, their free choice of indexing positions, and their tolerability of extremely high radial and axial torques during rotation and stopping.

Direct Drive Indexing Table will be free of defects for a long time and does not require any repairs. Based on the application requirements, this product can be equipped with hydraulic or pneumatic clamping system.

Direct Drive Indexing Table Features

High torque output direct drive with a compact design
Maximum dynamics thanks to the use of torque motors
The very high/ low rotational speed with minimum cogging torque
High-speed precise indexing operation
Outstanding low runout and high stability by employing a special bearing
Short positioning time
No face gear results in zero backlash and maximizes the performance
Free scale angular steps
High accuracy between ± 3 arc second
High repeatability means less than 0.2 arc second
Pneumatic or hydraulic clamping system for more rigidity of table head
Few mechanical parts result in very long life and low maintenance
Possible custom design
