Thank you for your interest in Motion Index Drives.
Dear Sir,
What is the motion curve employed by you for your indexers.
Do you use a parallel shaft indexing cams or globoidal cams.
How do you ensure the additional accuracy as claimed.
Can this mechanism be employed for CNC tool turrets coupled with
a hirth coupling .

Hello Pankaj,
Sorry for the late response, hopefully this can answer your questions:
Motion Index Drives uses a modified sin curve for all of its cams (parallel, globoidal and barrel); years of experience and testing have shown us that this is the best cam profile for almost all applications.
NANO technology is only applicable to barrel cams currently. The additional accuracy is reached through a specific system which adjusts the cam during dwell with an encoder and control device.
NANO indexers are primarily utilized in assembly, testing and printing machines. It can be used instead of a Hirth coupling system, but we would have to ensure that the machining forces are not too large because they could damage the unit. The Hirth system can also handle large machining forces, and we can’t exactly compare the two systems.
