CNC Touch probe – 3D Finder

The 3D Finder touch probe is a mechanical probe sensor used with CNC fabrication centers and CNC lathes. A touch probe such as this is used for various functions, for example, to quickly detect the position of the workpiece before machining, to perform adaptive machining, to scan, copy, and measure workpiece geometries (edges, holes, angles), and to perform quality control.

Note: This probe is active, i.e. it requires power. Probe tip diameter – 2-mm.

Touch Probe sensor – applications and benefits:

Fast zero-point acquisitions
Workpiece digitization and copying
Surface flatness acquisition
Workpiece Scanning
Quality control

Sensing directions:	±X; ±Y; -Z
Max. Stylus overtravel	XT = 12°; Z = 5mm
Trigger force:	XY = 0.5 – 1 N; Z = 2.5 N;
Repeatability (unidirectional):	1 μm (max 200 mm/min probing rate)
Output function:	Electronic high-speed switch as normally closed contact
Switching current:	max. 30 mA
Functional notification:	switching point notification via LED
Cable length:	1 Meter (without connector)
Enclosure:	Stainless steel
Connecting shank:	Cylindrical 8 mm Length: 20 mm
Size without stylus:	Diameter: 39 mm Height: 49 mm
Size stylus:	Diameter: 8 mm Height: 27 mm
Ruby ball tip:	Diameter: 2 mm

Clamping

The 3-D Finder touch probe has a shank diameter of 8 mm, which means it can be clamped with an 8-mm ER collet.
It is constructed entirely of stainless steel.
Unlike inexpensive workpiece probes for hobby use, this probe features mechanical calibration to align the probe axis perfectly with the spindle axis.

Connection

This probe is “Active” and therefore requires a power supply. The connection with the machines is achieved using 4 wires: one being the power supply, either 12V or 24V, one GND, a third is the output signal, attached to the CNC controller input, and the fourth is configured as illustrated in the diagram depending whether you use an NPN or PNP control board input.
The switch output is normally closed, hence the probe is compatible with all control boards using normally closed input such as Mach3, Twintec Colibrì, QEM Rosetta, Heidenhain, Fanuc, OSAI, Siemens, and many others. A normally open version is available on request.

Hi Robert,
Check if you have input pins available in the controller:

The connection with the machines is achieved using 4 wires: one being the power supply, either 12V or 24V, one GND, a third is the output signal, attached to the CNC controller input, and the fourth is configured as illustrated in the diagram (have a look at the photos of the probe) depending whether you use an NPN or PNP control board input.

I have a 3d touch probe that I did buy one year ago in your shop. Now I need some spare parts. The PCB with the 3 balls on it is damaged. The CNC machine did not stop and did break the touch sensor. The PCB is cracked and bend. And the touch pin that touches with the safire ball on it is broken. I have pictures from the broken parts. Where can I send them?

Good Day, is the 3D Finder CNC Touch Probe compatible with Mach 4 using with Pokeys57CNC Controller?

Q Good Day, is the 3D Finder CNC Touch Probe compatible with Mach 4 using with Pokeys57CNC Controller? answer now
Asked by Sybrand Coetzee on January 21, 2019 9:03 pm

Answered by the admin Hello, I don't know the Pekeys57CNC controller but the touch probe works with Mach3. Have a look at the connection diagram to connect the probe to you controller board. "This touch-probe is “Active” and therefore, have to be powered. The connection is made by 3 wires: two wires for the power supply 12 – 24V and GND, and the third wire to connect the input to the CNC controller. This input contact is normally closed. let me know if you have doubts or you need further information. You can place order online from this page.

A Did you get this working with Mach 4?

Answered by the admin
hello, i don't know the plugin Pokeys57, but We have a lot of clients who use it with mach3 and mach4

Good morning I'm currently looking for a new probe touch probe 3d mesuring sensor - 3d finder so i can digitize a surface my previous probe couldn't handle rapid commands with .002" stepover while digitizing . I think it has to do with the jerking motion from the machine. how well can this probe handle . and if i buy this probe and turns out it does the same can it be returned Salvador Gomez CHROME HEARTS Hollywood CA

Answered by the admin hello Salvador, I think this touch-probe will work for you. Anyway, if it is not ok for you and if you don't damage it you can send back the probe and we refund the total amount. You pay only the return shipping cost. let me know if you need help to place the order.
