Effecto’s Epsilon line of automatic tool changers employ a Cam & Dowel method of engagement and disengagement, as opposed to the Ball & Collet method employed by many of our competitors.

Here are a few of the benefits of using Cam & Dowel tool changers.

• Wear compensation – cam and dowel systems “wear in” instead of out, maintaining like new performance throughout the lifetime of the tool changer
• Low cost of maintenance – Maintenance is performed simply by checking the bushings, locating pins, and if needed, greasing the cams.
• Maintenance – Effecto/Applied Robotics offers a lifetime guarantee on the coupling mechanism parts for their line of Epsilon tool changers
• Ease of integration – direct bolt design to limit the need for adapter plates
• Suitable for harsh environments
• Self-Cleaning
• Positive cam retraction – air is required for both couple and decouple. When ball & collet systems are exposed to dirtier environments the potential exists for the balls to become jammed in the collet, prohibiting proper and safe release.
• Safety (to both personnel and equipment) – when a guide pin breaks on a ball & collet system the end-of-arm tooling can “free-wheel”. This is not a concern with Epsilon XCHANGE cam & dowel tool changers.

A few other things to consider when it comes to the Effecto (Epsilon XCHANGE) line of tool changers:

• Have a high strength aluminum alloy body
• Are self-centering
• Optional couple/uncouple sensing is available upon request
• Can pass thru electrical wires, fluid (coolant), as well as pneumatic air lines
• Can incorporate all pneumatic, hydraulic, electric, and electronic coupling modules & components
