5. Hardinge engineered mechanical elements guarantee the spindle will be accurate repeatable reliable and flexible to suit many different machining applications The spindle carries a centerline from the machine bed of 6 00 152 4mm which is compatible with many other in dexing products The spindle is hardened and ground for accuracy and has a rigid design with dual angular contact bearings to sup port heavy cutting forces Positioning of the spindle is accomplished through a self locking gear set 1 2 High Stiffness Overall System The Hardinge 16C and 3 Rotary Indexer System uses a high quality hardened gear system with a 60 1 ratio This type of gearing allows for an efficient forward driving capability motor side through the worm while at the same time preventing back driving from occurring by the applied cutting forces at the spindle side This is an impor tant operating characteristic of the high ratio gear system since it adds stiffness into the machining operation This spindle is also equipped with a high torque pneumatic fail safe clamp which prevents chatter and adds a con siderable amount of stiffness Stiffness or rigidity is one of the more important features of any system employed in the activity of machining operations and is the driving force for Hardinge engineered rotary systems 1 3 Machinable Part Size The Hardinge 16C and 3 Rotary Indexer System has been designed for those parts that can be conveniently clamped to the
