1.Clamp the probe on the machine spindle through the tool holder, and loosen it slightly.The two opposite fastening screws at the bottom can adjust the four symmetrical adjustment tops on the side.The ball head of the wire adjustment probe coincides with the center of the spindle. 2.There is no need to rotate the spindle when measuring the centering, and the centering measurement can make the probe rotate Turn 180° to make the measurement more accurate. 3.The probe supports measurement in three directions, X, Y, and Z, with reciprocating positioning accuracy less than equal 0.01, X Y deflection range 0-6°,Z direction telescopic range 1mm, exceeding Leaving the safe range will damage the probe and probe. 4.The probe has two built-in CR1616 3V lithium button batteries(not include),Loosen the fastening screw and adjusting top wire when it is insufficient, remove the top cover to replace it,Pay attention to the positive and negative poles of the battery when replacing, and re-adjust the probe center position after replacement Set. 5.The side head does not support the detection of insulating materials and insulated machine bed. Name:The photoelectric 3D edge finder The probe supports dust and a small amount of dripping and water resistance, do not drip for a long time Dimensions: repeat positioning 0.01,Z direction stroke 1mm, XY swing about 6 degrees. Probe thread , ball head diameter 4mm, length 40mm. The detection of insulating materials and insulating spindles is not supported. Power Suplly:two CR1616 3V lithium button batteries(without battery) Type:Green Light Colour:Gray Material:aluminum alloy Package Contents: 1 * 3d photoelectric edge finder Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
