Z Rail
The Z-rail travels vertically at right angles to both the X and Y axes. The rail has
an octagonal cross section and moves virtually without friction. The rail is made
from a lightweight, hardcoated aluminum and is supported by eight (8) air bear-
ings in the ZX carriage.
A pneumatic counterbalance, adjustable for varying probe weights, is mounted in
the Z-rail. The counterbalance consists of a cable suspended piston in a cylinder.
The Z-axis measuring scale is recessed in the back of the rail. The scale is par-
tially exposed when the Z-rail is in its lowermost position. Two mechanical stops
with elastomeric bumpers control the travel of the Z-rail.
Note: These stops must
not be removed or the rail will drop on the table.
The Z-rail has a built-in failsafe brake that operates off the pneumatic system.
If air pressure is lost in the counter-balance, the Z-axis air bearings will
lock, preventing the rail from dropping
on the work table.
A probe holder built into the bottom
of the Z-rail has a locking lever and
spring plunger detent to hold the
probe in place while clamping. The
orientation of the locking lever can be
changed by pulling the lever out to
disengage it from its spline and
reengaging the lever in a new location.
When engaged, the lever can be turned
to clamp or release the probe. The
Z rail has a mouse with a button for
moving the cursor on the monitor
screen, a button for selecting menu
items amd a button to record measure-
ment points.
The machine is prewired to accept the optional Touch Trigger Probe. A cable
is assembled thru the center of the Z-rail with a socket at the lower end
of the rail for electronically connecting the Touch Trigger Probe.
