Speroni, a Big Kaiser brand, offers integrated automatic mechanical clamping Capto spindles for all of its presetter models. The system applies a tool-clamping force of more than 550 lbs. to seat Capto tooling into the presetter spindle similar to the way it is drawn into a machine tool spindle. According to the company, this increases precision and repeatability. Available in Capto sizes C3, C4, C5, C6 or C8, the spindle can be retrofitted to any of the company's presetter machines.
