The Chopper series is a well thought out spindle concept that integrates the various tool clamping systems into just one basic module. Manual change, pneumatic direct change, and taper change are all three possibilities. The integrated ventilation system also saves on costs for an external cooling unit. Cutting down production costs without forfeiting quality was the focus during the development of the Chopper series. The result is a full-fledged product at a low price.
