Sanjet International Co., Ltd.

High-speed variable-frequency automatic tool changers

2014/08/01 | By Ken Liu | SANJET INTERNATIONAL CO., LTD.

Sanjet International Co., Ltd., a leading Taiwanese maker of automatic tool changers (ATCs) and tool changing systems, has introduced a series of high-speed variable-frequency automatic tool changers (ATCs) under the "SKDI" name.

The new series is noted for efficiency in saving energy, boosting output, and protecting spindles from being hit by tool arms while the cutter is being changed. The changers have a simple mechanical structure that makes them easy to maintain.

Sanjet developed the SKDI series to meet the growing demand from mainland Chinese and Southeast Asian makers of car parts, motorbike parts, and molds for machine tools with the ability to operate for long hours and change tools efficiently.

SKDI-series changers have a variable-frequency driver which controls the motors that drive the tool magazine and the changer. Thanks to its electronic brake, the driver conducts much more accurate tool-changing positioning than do traditional drivers, which use a linear brake.

SKDI changers can change a No. 40 cutter in 1.4 seconds and a No. 30 cutter in 1.2 seconds. They are compatible with off-the-shelf vertical and horizontal machining centers and can work with PC Base, Fargo, Heidenhain, Siemens, Fanuc, and Mitsubishi controllers.

Dedicated to providing the possible best service, Sanjet has devoted considerable resources to researching the problems of engineering tolerance that are common with material feeders and assembly lines, and has provided the results to customers for use in optimizing processes and technology. (KL)
