Spindles attached to a robot’s arm must be flexible, durable, and meet the payload limitations of the robot for proper robotic machining. Robotic machining presents unique challenges, like lightweight construction to minimize payload stress, contamination protection, and operation from several angles.
Robotic spindles should match the manufacturer’s needs. There are lightweight, small models to fit into tight spaces, as well as robust, powerful models that are ideal for harsh material removal operations. Dependent on the needs of each application, a spindle should be chosen with care.
A spindle for drilling applications should be selected after considering the hole diameter and depth, the tolerance, and a need for additional machining. Robotic milling (engraving and routing applications) spindles are used when high-speed material removal or high precision surface finishes are required. Grinding spindles use a grinding wheel to grind away metal, glass, ceramics, or other materials to the desired shape or finish. Deburring and deflashing spindles are designed with high speed and low torque. Buffing, finishing, and polishing spindles should allow the tool to glide gently over the finished part with high RPMs and low horsepower.
Dynomax and FANUC teamed up to create a flexible, durable robotic arm spindle line. The collaboration resulted in a robotic system that saves time and lowers costs for material removal while committing to exceptional product quality. The 14-2A-C-1370 spindle is part of the series of high performance spindles with low weights in order to minimize payloads. This spindle is designed for robotic material removal on several FANUC robots, including the F-200iB, M-16iB, M-710iB, M-900iA, R-20000iA, and S-500iB. The 14-2A-C-1370 spindle is one of 50 robotic spindles in this line with a robust deisgn. It offers superior contamination protection, and is compact and lightweight. Its ceramic bearings and water cooling extend its life and allow higher speed operation.
Dynomax also revealed a new robotic spindle matrix deisgned to reduce spindle selection for material removal robots. The matrix is downloadable and pinpoints the best spindle tool for each robot and specific application. Matrices are available for FANUC, KUKA, and Motoman robot manufacturers. RobotWorx is an authorized integrator of all three of these robot manufacturers. If you are interested in any of their robotic spindles, contact us today on how to implement one.
