Hello the company I work for has a Okuma cadet v4020 with a umbrella tool carousel the carousel is set up to run a bt-40 tool holder it is the only machine running a bt-40 tool holder. Can the tool carousel be converted to run a ct-40 tool holder ?. I can run a ct-40 tool holder in the spindle but can not put it in the carousel do to the fingers being set for a bt-40 tool holder.
