Precision collet chuck Features * US regulatory tools most commonly used specifications * Front CPD collet series collet chuck power push US regulatory tools using the most common type 5C (maximum clamp diameter 26mm) and 16C (maximum diameter of 40mm clip ) collet when work before pushing the locking collet sleeve. Work does not matter axial displacement .CPD power collet chuck has a flat back and A2 type flange can be used. can be used with a variety of CNC machine tool spindle nose job . with US regulatory 5C and 16C elastic tube clip work before pushing the clamping sleeve, no axial displacement of the workpiece can be installed on CNC lathes, milling bed, or all kinds of special machines working standard A2 type flange mounting flange standard flat back installation clamping accuracy 0.030mm - standard collet clamping accuracy 0.020mm - especially for precision collet and collet chuck size Performance Specifications - A2 flange CPB-5C- collet chuck model CPD-5C-A5 CPD-5C -A6 CPD-16C-A5 CPD-16C-A6 CPD-16C-A8 spindle nose A2-5 A2-6 A2-5 A2-6 A2-8 A 137mm (5.39 ") 158mm (6.22") 137mm (5.39 " ) 158mm (6.22 ") 220mm (8.66") B (mounting screw hole) 104.8mm (4.13 ") 133.4mm (5.25") 104.8mm (4.13 ") 133.4mm (5.25") 171.4mm (6.75 ") C 82.6mm (3.25 ") 106.4mm (4.19") 82.6mm (3.25 ") 106.4mm (4.19") 139.7mm (5.50 ") D (maximum trombone tooth diameter) Max.
