APC system (continued)
APC probe family
The APC family of tool setting probes currently
consists of:
• APCA air extension and air retraction
• APCS air extension and spring retraction
The term APC used throughout this installation
and user’s guide refers to both versions.
Features
The APC features an “air bleed” function. “Air
bleed” is where air ows through the APC
mechanism at a constant rate over the stylus cube
when the APC cover is extended or retracted to
help prevent build up of contamination on the
stylus cube.
The APC also features an air blast port.
The customer can supply, t and control an air
blast pipe to suit their requirements. For example
this could be used for cleaning the stylus or
cutting tool before measuring.
NOTE: A retract conrm sensor provides the
machine controller with a signal to indicate that
the APC cover is retracted.
