To enhance the centerless grinding operations used in manufacturing, CRI has developed a 3-day training program for engineers and operators. The training consists of a theoretical session coupled with hands-on sessions. The theoretical section will be in a classroom setting. For the hands-on session, CRI will make centerless grinders available.

Fall dates to be announced soon.
