Probes for CNC Machines
Measure parts in 3D while they're still on your CNC machine. These probes integrate into your machine’s control system to save you time and help you keep parts in tolerance while machining. Because they measure with a stylus (not included) that physically touches your part one point at a time, they accurately check distances, diameters, and angles. They can also be used to position a workpiece, locate holes and grooves, and check for scratches and dents. However, they don't work well on more complex measurements, like how round or flat a part is. IP rated, they’re watertight enough to handle submersion, so you don’t have to worry about coolant seeping in.
All probes require a receiver and an interface (sold separately) to communicate with your CNC machine. Receivers send your probe’s data to interfaces, which need to be wired to your machine’s control panel.
Infrared probes send data to a receiver up to 5 meters away, but because they use light, they need a clear view.
40 mm probes are typically found in small and medium machines with a chuck size between 6" and 15".
Receiver mounting brackets (sold separately) make it easy to attach a receiver or receiver/interface to your machine.
Use a shank (sold separately) to attach a probe to the spindle on your CNC machine. Add a shank adapter (sold separately) to fit 40 mm probes to shanks made for 63 mm probes.
Conduit assemblies (sold separately) protect wiring from coolant and metal chips.
