Korea Epson Launches Six-Axis "CX-A Series" Robots Optimized for Compact Manufacturing Environments

Improved Wrist Rigidity and Expanded Range of Motion
Broader Payload Selection with the Addition of 7 kg Models

Korea Epson announced on June 24 that it has launched the "CX-A Series," a six-axis vertical articulated robot capable of high-precision operations from various angles, even in confined spaces.

The "CX-A Series," the successor to the previous "C4-A," consists of three models: the "CX4-A601," which supports a payload of 4 kg, and the "CX7-A701" and "CX7-A901," both with a payload of 7 kg. The new products have reinforced the rigidity of the end wrist joint (J5) to minimize structural deformation caused by external loads or repetitive movements.

In addition, the holding torque and driving stability of the fifth and sixth axes have been improved to enhance operational precision during stops and directional changes. This ensures that structural alignment remains stable even in collision situations, providing consistent work quality even in heavy-load environments.

The "CX-A Series" also features an expanded four-axis range of motion and work area, increasing its flexibility for tasks in tight spaces or complex processes. Notably, the area where operations can be performed without posture changes has been widened, enabling smoother motions for continuous tasks such as coating and polishing. This reduces the need for process transitions between work steps, shortens cycle times, and lowers the possibility of cable twisting, thereby enhancing operational convenience and system stability.

Maintenance convenience has also been strengthened. The "CX-A Series" adopts a batteryless encoder, eliminating the need for battery replacement and enabling operation without separate battery management. As a result, maintenance burdens are reduced, production line downtime is minimized, and equipment operational efficiency is improved. The series is compatible with Epson's RC800-A controller and RC+ 8.0 software, making integration with existing systems easy.

The newly introduced 7 kg payload models in this series target market demands that are difficult to meet with 4 kg-class robots and where 8 kg-class equipment would impose excessive costs. The main target industries include electric and electronics, automotive, and cosmetics, which are sectors with high automation needs due to the coexistence of precision assembly and diverse processing environments. In particular, the automotive industry is receiving attention as a new application field, as demand is rising for more flexible robot operations in response to the expansion of electronic components and diversification of production processes.

Yongwook Lee, Head of the Robotics Division at Korea Epson, said, "Industries are evolving to require high precision and multi-process capabilities even in compact manufacturing environments. The CX-A Series addresses the limitations of our existing lineup and will become a key product contributing to the expansion of Epson's robotics business portfolio by supporting a wider range of automation industries."
