3D Finder measuring probe for determining the zero point of the workpiece
Design of the 3D-finder
The housing of the 3D measuring probe is made of stainless steel and shows a lasered logo of the manufacturer. A plastic ring is embedded in the housing of the 3D-finder, which is equipped with RGB light. When you put the probe into operation, a green light appears, and as soon as the probe touches the workpiece it triggers the switching signal, and the light turns off.
The high precision of this touch probe
Specifically, the 3D-finder can be optimally adjusted and calibrated for your own CNC machine. This ensures high precision and repeatability during machining. For example, the combination of probe and machine achieves an accuracy in the range of 0.02 mm. However, this also depends on the machine which is used.
Use the four fixing points / adjusting screws on the probe initially for coarse and next also for fine admission calibration of the 3D measuring probe.
Simple and fast calibration
Accordingly, the 3D-finder can be clamped directly into the milling spindle. For this, you can use an 8 mm collet chuck. Of course, there is also an optional adapter for the Euro neck mount with 43 H7 available.
First, calibrate the measuring probe with the help of a conventional fine probe or dial gauge. After you have achieved the desired result, tighten the two fastening screws. In conclusion, the probe is now ready for operation.
Features of the 3D-finder touch probe
The 3D-finder itself has a receptacle with an 8 mm shaft diameter. At the exit of the probe tip, there is a bag below which protects the probe from contamination by dirt and chips. The probe is supplied with a 25 mm long probe tip with a 2 mm diameter ball by default.
Plug&Play for GT5 machines with Pokeys57CNC CNC controller
For this reason, we have prepared a special offer for our machine customers. You can purchase a set that enables the connection to our Pokeys57CNC controller. Practically plug&play and off you go.
Connection of the measuring probe
In connection with our machine controller Pokeys57CNC and control software Mach 4, furthermore, you can approach bore centers and workpiece edges. The 3D-finder can be connected via the port for the C-axis (connection for the 4th axis).
In other words, this means that it is possible to connect a 4th axis, such as a rotary axis or a tangential knife, at the same time.
You can use the 3D-finder to measure manually or move to edges or likewise use one of the macros* supplied likewise.
Mach 4 software has four different automatic measurement options.
That is why you can start these options directly via the four individual buttons in the software. After determining the center of the hole, the diameter of the hole is also displayed in the program. In addition to this, the determined zero points of the hole are set automatically.
