5、r.No further reproduction or distribution is permitted.Uncontrolled when printed.FOREWORD Throughout American industry a variety of methods and mechanisms are used to drive twist drills,reamers,etc.In the automotive and other mass production industries,the split-sleeve collet drive has proven useful
6、.Two engineering reasons for its suitability are:(1)Multiple spindle drill heads can be designed with spindles on a very close center-to-center distance;(2)Bushing plates do not have to be moved when tools must be replaced.The splitsleeve collet driver is designed to drive straight shanks in sizes$6
7、1(0.0390)inch diameter and larger.As the assembly of split sleeve collet-type driver necessitates manufacture to close tolerances,it was deemed advisable to develop an American standard to insure that collets would fit drill shanks as shown in ANSI 894.1 1-1967.The required ASA approval and designat
