ACS-E 3 Self centering column chuck
Self-centering column chuck with pull down Ø 110 - 350 mm
■ Pull down ■ Power operated via standard cylinders ■ O.D. clamping
Application/customer benefits • For small, medium and large quantities at high precision • Pull down of the workpiece to the axial workstop during clamping • Minimum loss of gripping force at high speed • Standard, hardened jaw blanks available Technical features • Chuck body completely case hardened • Openings in the chuck body to evacuate chips
• Central bore for coolant / air Standard equipment
