  • Page 23: Probe Moves

    PROBE MOVES A probe trigger signal is generated when the probe is in the operating mode and the stylus is driven against a surface and is deflected. The machine control records the probe contact position and instructs machine motion to stop. High probing speeds are desirable, however a probing velocity must be chosen which allows the machine to...

  • Page 33: Diaphragm Inspection

    DIAPHRAGM INSPECTION PROBE DIAPHRAGMS The probe mechanism is protected from coolant and debris by two diaphragms, these provide adequate protection under normal working conditions. The user should periodically check the outer diaphragm, for signs of damage and coolant leakage. If this is evident replace the outer diaphragm.
  • Page 34: Diaphragm Replacement

    OUTER DIAPHRAGM INSPECTION 1. Remove the stylus 2. Unscrew the front cover. 3. Inspect outer diaphragm for damage. 4. To remove outer diaphragm, grip near the middle and pull upwards. INNER DIAPHRAGM INSPECTION 5. Inspect inner diaphragm for damage. If damaged return the probe to your supplier for repair.
