We have finished the first batch of Z columns and got the first one
assembled and test yesterday. Ends up with 16" of Z travel and much
greater rigidity. With the 4 TPI Kerk precsion leadscrew we use as
our standard configuration I was running reliably at 90 ipm on the Z
using an Xylotex controller and Mach2 with a 234 oz/in stepper.
Based on customer input we added the ability to mount the column on a
2000 ram without using the 5400 style mounting base. So owners of
2000 based machines that are running our extended Y base have the
option of using the column in a 5400 configuration for maximum
rigidity or removing the mounting base from the Z column and bolting
it onto their 2000 ram when they need the reach at the sacrifice of
rigidity.
Some details on the column.
It will ship with the saddle and screw already assembled.
This starts our as 30 lbs of 6061 billet and ends up at just over 19
lbs when complete.
Finish is hard anodize and the Z column slide and saddle are Teflon
impregnated.
While the 4 TPI Kerk screw is the standard, we offer a 20 TPI or a
5mm/turn version as a no charge substitution.
The saddle portion has hole pattern to afix the motor mounting plate
that has 5 rows of holes. The motor mount plates have 3 rows of
holes. This means you can move the motor mount plate up or down to
give more usable range if you need the spindle higher or lower.
This motor mount arrangement also lets you change the mount plate to
a Taig version plate and then mount a Taig ER16 or standard spindle.
