Over the years OmniTurn has helped
automate more than a few Hardinge lathes. We have been
advocating the addition of both 2 and 5hp variable speed
drives. These systems have proven that they are reliable
and up to the task of supporting the requirements placed
on them. However as time has gone on we have found ways
to improve the systems. With most retrofits, the spindle
drive includes a vari-shiv drive belt for speed
adjustment and a clutch/brake assembly. These two items
add components that slow down and diminish the system’s
overall performance. The
vari-shiv belt system takes much more power to drive
than a standard belt system.
- The pulleys are 5 times
larger than a standard belt pulley. The inertia
added by these pulleys is significant in
hindering the stopping and starting of the
spindle.
- The belts for the vari-shiv
are very thick and require significant
additional power to drive.
- The vari-shiv system adds an
intermediate shaft with second belt. More belt
issues, additional bearings, and a shaft the
shiv rides on that wears out causing vibration
and noise.
- The clutch/brake assembly also
add additional mass and inertia problems. There is
also the issue of additional bearings and drive
shafts included in the system when they are not
really needed.
OmniTurn has come up with a system
where the intermediate shivs, belts, and drives are no
longer needed. You can remove all the heavy belts and
pulley and replace them with a single belt and simple,
smaller pulleys. The systems run much smother, quieter,
and with much less inertia. Older 2hp systems that had
problems shutting down while running shorter cycles are
given a new life with these direct drive system. The new
belt and pulleys take only 2-3 hours to install.
