With the extensive use of machining centers, the calibration method of the probe is as follows:

(Manual calibration) <<Measurement of the Z-direction coordinate value of the gauge block Performs the operation of the machine tool to return to the reference point. Many users also start using tool measuring devices. Not only can the tool wear condition be detected, but also automatic compensation (by modifying the tool compensation value) can greatly improve the machining efficiency and accuracy.

In addition, the use of its tool breakage detection function and tool life management function can also automatically find the same set of tools, saving time for tool inspection and replacement.

However, because the user does not know much about the measurement principle, it is easy to misunderstand when using it. Sometimes the precision of the stone engraving machine is not as good as the previous stone engraving machine, which makes the user confused and limits the extensive use of the measuring device.

The use of the tool measuring device mainly includes three steps: device and wiring; calibration; measurement.

1 device and wiring

Tool side measuring devices usually include probes and signal conversion devices (hardware) and related measuring sequence (package) probes (TS27R devices are on the workbench and should be kept away from the processing area as much as possible. External protection should be added before use. The guard is opened and the tool is blown clean with the wind (automatically controlled by the M code) to ensure that the tool is free of debris and the protection is turned off after the measurement is completed.

After the probe unit is completed, first adjust the parallelism and straightness of the contact surface of the probe. A dial indicator (or dial gauge DTI is sucked on the spindle head, the head is placed on the upper surface of the gauge block (circular or square); the X-axis is controlled by the hand wheel to move back and forth along the gauge block surface to observe the needle change, At the same time, adjust the adjusting screw on the probe to ensure the straightness of the X direction to tighten the screw after adjusting 0.010mm. Then control the Y axis to move back and forth along the outer surface of the measuring block, and adjust the adjusting screw on the measuring head to make the Y direction The straightness is also guaranteed to be tightened after the adjustment of 0.010mm. The conversion device (MI8-4 is installed in the electrical cabinet with a 35mm gauge rail.

It is necessary to pay attention to the DC24V regulated power supply for the conversion device. It is best to separate the power supply from the solenoid valve or the intermediate relay. If it is necessary to share, consider the anti-interference ability of the signal, otherwise the measurement result may be affected.

The calibration method of the probe is as follows: (manual calibration)

The determination of the Z coordinate value of the volume block performs the operation of the machine tool returning to the reference point to confirm the machine tool reference point.

Then select a standard tool (the exact length and diameter of the tool is known, such as the spindle check bar). Manually move the tool to 10 mm from the upper surface of the gauge block (start position) and select the MDI mode. Perform the following sequence: G65P9851K149.536K The Z-direction coordinate value of the gauge block is established after the calibration cycle is entered and the exact length of the selected standard tool is entered.
