Introduction

Getting Started

On initial setup or every six months, you should calibrate your wireless intuitive probing system. Here is how to quickly get this done in just a few steps.

Calibration of the WIPS option must be completed before any tool or part probing can commence. Calibrate after any disturbance to the work probe stylus or when the tool probe tip needs replacing.
  • Calibration of the WIPS option must be completed before any tool or part probing can commence.

  • Calibrate after any disturbance to the work probe stylus or when the tool probe tip needs replacing.

  • Calibrate the probes every six months for correct reference to the machine axes.

  • Go to Step 6 if your machine has not been calibrated in the past 12 months.

  • Rotate the probe by hand to check runout.

  • If runout exceeds 0.0005" or 0.013 mm, adjustment is required.

Test Indicator accurate to 0.0005" or 0.013 mm Magnetic Base to mount the Indicator
    • Test Indicator accurate to 0.0005" or 0.013 mm

    • Magnetic Base to mount the Indicator

    • "Calibration Bar", generally consisting of a 1/2" or 12 mm gauge pin clamped in a collet style toolholder.

    • "Ring Gauge" typcally with a 2.000" or 50.000 mm bore.

  • Note: an accurately bored hole in a part or fixture can also be used in place of the Ring Gauge.

This is how to adjust the runout of the Work Probe stylus. First, Insert the Work Probe into the spindle. Place the magnetic base on the table and align the indicator tip to the probe's stylus.

  • First, Insert the Work Probe into the spindle.

  • Place the magnetic base on the table and align the indicator tip to the probe's stylus.

  • Jog the axes in 0.001 inch increments until the indicator touches the stylus.

  • With the indicator tip set against the stylus press E-STOP, so the probe isn’t accidentally ejected during adjustment.

On the probe body, loosen the two upper LOCKING set screws slightly, and then lightly tighten them. WARNING: The four lower sets of screws adjust the position of the stylus mount. Very small adjustments have a large effect on the stylus runout. Decide which direction the stylus needs to be adjusted to reduce runout.

    • Loosen and then slightly tighten the two (2) opposing screws which are NOT inline with this direction to add some friction.

  • Gently loosen the second set of (2) opposite screws. These will be used to push the stylus mount into alignment.

  • Tighten the screw ON THE SAME SIDE as the highest indicator reading. This moves the stylus tip away from the indicator.

  • As you tighten the “pushing” screw you will need to loosen the opposite adjustment screw and locking screw slightly to allow movement.

Continue to adjust inward with each set of screws to reduce the runout as close to zero as possible. When runout is below 0.0005" or 0.013 mm, carefully tighten each upper locking screw while at the same time tightening the opposite lower adjustment screw.

With the locking screws tight, check the runout at the stylus one more time. Now that the work probe stylus is centered, calibration of both proves can begin.
