I am interested in extending the Z axis travel on my Taig CNC mill. Also I would like to know if Z axis bracing would improve the mills precision.
I think the Z axis travel could be easily extended by making three longer parts. These parts are shown in the attached diagram.
The longer parts would replace the Z-Axis 3" Steel Box Way (200-42), the Z-Axis 1 1/4" Steel Box Way (200-43) and the Z-Axis Leadscrew (LH) (200-25A). The longer parts should bolt right in. Does anyone know what kind of steel Taig uses in the 3" Steel Box Way and the 1 1/4" Steel Box Way or what kind of steel would be appropriate? Could I use the Taig X-Axis Leadscrew (RH) 2018 (200-26) for 9.5” of Z travel? Or even the X-Axis Leadscrew (RH) 2019 (200-26A) for 12” of Z travel? How much extension could be accomplished in this manner without causing problems?
Another modification would be replacing the Z-Axis Leadscrew with a ballscrew, this would require additional parts and modifications. Would a ballscrew on the Z axis and Acme screws on the other axes cause problems?
The Taig mill and the Sieg X2 Mini Mill have a similar method of attaching the Z column to the base. Several people working with the X2 have developed braces as described here: http://www.hossmachine.info/Shop_Info.html#x2%20column . Would a brace for the Taig column be a good idea? Has anyone developed a brace system for the Taig?
Thanks.
