Re: [CAD_CAM_EDM_DRO] PIC DRO

Can you post a url for W. M. Burg and Stock Drive.

I haven't got a clue as to what you are on about, are these shaft couplers to attach steppers or encoders to a shaft in the context you are refering?

Regards,

Terry.

These are one piece of aluminum, which has one or more helical
slits in it, which makes it into a kind of spring. The idea is that
it is flexible in the axial direction, and also to an angle from the
axis, but is very stiff in torsion. These can be easily bored up
on one side if there is a change in shaft size. I have gotten a
number of them from various machines, but they are also available
from most of the catalogs. W. M. Berg and Stock Drive
products have a vast selection of these types of items.

The aluminum units are the lite duty line. They can be had in other materials
including stainless steel. Prices go up but the torque ratings are in some
cases 3 or more times higher for the same unit.
