TOOLING SYSTEMS INTRODUCTION INTRODUCTION Power Chucks With this tool, only a small tightening torque compresses the frontal nose, providing an extremely high gripping 3 2 1 force. It is designed for roughing and finishing applications in milling where high torque transmission, maximum accuracy, compactness and easy operation are required. Features • The clamping nut is not threaded (as in ER collet chucks) 10 • Designed for direct chucking of the tool shank – no need for intermediate collet for maximum gripping force • Sealed nut construction • No axial drawback of the tool shank as chuck is tightened • Thick wall construction to withstand greater side 11 9 8 5 4 6 7 loading forces 1 Shallow tapered front end cone The high gripping force achieved by the MAXIN POWER CHUCK results from the shallow nose tapered cone (1) with 2 Clamping nut helical slot (3) inside the internal chuck bore. It exerts a very 3 Helical slot high clamping force when the clamping nut (2) is rotated in the axial direction.The shallow taper of the tool nose (1) 4 Needle bearing cage and the angled position of the needle bearing (4) that sit in 5 Front seal the cage create the axial movement of the clamping nut (2). 6 Ventilation bore (thread M4) This unique clamping mechanism eliminates axial movement of the shank while clamping, 7 Preset screw thread simplifying the preset process. 8 Cap screw (for the preset screw) Runout Accuracy 9 Preset screw Maximum runout at 3XD overhang is less 0.01 mm 10 Ground bore 11 Grip groove (for collet release) 3xD 0.01 D 556 ISCAR
