Has anyone used these guide bushings?

Our products

We are looking at putting one of these in a fixed GB R-series Citizen machine. The machine would be setup for 0.125" Ti and that's it. We are hoping that this will be very precise and allow Ti to run in a fixed GB machine with high RPM spindle.

Any experience would be helpful!

Hi

We use these Habegger roller guide bushes extensively for machining titanium medical parts. They produce very good results and can be run at high speed. One big advantage is that they virtually eliminate the problem of the titanium bar stock jamming in the guide bush as the sliding friction is very low.

You must provide the bush with a constant flow of clean filtered cutting oil to prevent the cutting chips from contaminating the rollers. We use a 20um paper filter element.

How much variation in bar size is acceptable for the unit?
thanks

It will be dependant on bar size and material, but these bushes will tolerate a slightly bigger size deviation than a conventional carbide lined bush. They can be run much tighter than a conventional bush without the risk of jamming on high spots.

You would need to consult the manufacturer for exact bar size guidelines.
