The Zero Point Clamping System is a quickchange fixture that combines ease of alignment, accurate positioning, and high clamping forces with hydraulic or pneumatic actuation. Is said to reduce machine setup procedures into one step. Unlocking and removing the clamping device is simpler; the system eliminates the need to search for the bore. Is compact but reportedly provides holding and pull-in forces. Balls are 784% larger than those used in competitive locking systems. Balls roll freely in the form-fitting ball channel. Stainless steel components.
