They will fit in your machines existing yoke or our heavy duty yoke
Zero backlash nut with integral wiper

The yoke is a big part of the precision of your CNC. No joke! This first picture displays a standard oriental yoke and a Bridgeport yoke next to our yoke.

Our new yoke eliminates the "springy lash" that develops in the Y axis with a small undersized yoke.
We have a model for Taiwanese Mills and for Bridgeport Mills.

As you can plainly see we have the "beef".
Our Yoke is constructed using a steel alloy that is
much stronger than cast iron.

Here is a real example of how our CNC knee mill retrofit kit machined a part that a big expensive machining center could not!

The part pictured here is 30" in Diameter. The part would not fit on the customer's bed mill. Their was not enough Z clearance.

So the handy Centroid equipped CNC knee mill was used to cut the detail on the ring.

To fit the ring on the machine they swiveled the turret and put the table though the ring and fastened it to an angle plate that was bolted to the table
