High-speed/High-accuracy cam grinding CL-spec

This model performs grinding of non-circular workpiece like cam ring at a higher speed by having thrust of X-axis liner motor which is 2.2 times bigger than conventional models. Machine width 750 mm is achieved by having a low center of gravity and floor space is reduced by 47%. Also grinding programs are easily made from CAD/CAM by a dedicated software.

SRS (Smart Robot System) Option

SRS (Smart Robot System) with ceiling-mounted robot on the side of the machine allows to efficiently use the bottom space of the robot, which realizes space saving of installation area in automation system. Robot can be placed either side of the machine, which is flexibly adopted for various production lines. It also secures operation area in front of the machine which allows to keep the same workability as a stand-alone machine.
