Dividing Heads with Globocylindrical Cams use a globoidal cam surface and a cylindrical roller follower. The cam rotates continuously. The follower engages the cam’s helical groove. This motion indexes the spindle to precise angular positions. The cam’s geometry locks the spindle without a brake. Backlash cannot occur. You use this device for gear cutting, milling splines, or drilling hole circles.

FAQs about Dividing Heads with Globocylindrical Cams

What does a globocylindrical cam dividing head do?

It indexes a workpiece to precise angular positions. The cam rotates and moves a follower, and The spindle stops at set angles without a brake.

How do this cam indexer eliminate backlash?

The cam’s curved surface forces the follower into a tight groove. Multiple rollers contact the cam at once. This removes all free movement.

Can I use this cam indexer on a manual milling machine?

Yes, you can mount it on a manual mill. Turn the input shaft by hand or handle. The cam creates the indexing motion.

Does it replace a worm gear dividing head?

Yes, it replaces worm gear units in many applications. It offers higher stiffness and no backlash. Worm gears wear faster under heavy loads.

How do I mount this dividing head?

Bolt the housing to your machine table. Align the spindle center with the machine’s axis. Clamp the tailstock for long workpieces.

Can this Cam index continuously for spiral milling?

No, it indexes with dwell periods. For continuous rotation, use a different mechanism. Globocylindrical cams produce intermittent motion.
