Probes for CNC Lathes
Take 3D measurements even in the harsh machining conditions of a CNC lathe. IP rated and built with a strengthened glass window, these probes seal out coolant and resist scratches from flying metal chips. Integrate them into your lathe’s control system to catch errors while your part is still on the machine—saving time and cutting down on material waste. Since they physically touch a 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, dents, or other imperfections. However, they don’t work well on more complex features, like how round or flat a part is.
All probes require a probe styli. You’ll also need a receiver and an interface (sold separately) to communicate with your CNC lathe. Receivers send your probe’s data to interfaces, which need to be wired to your lathe’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. These probes are typically found in small lathes with chuck sizes around 8” and medium lathes with chuck sizes around 15”. They can also be used on a 5-axis CNC with a table size under 1,500 mm.
Receiver mounting brackets (sold separately) make it easy to attach a receiver or receiver/interface to your lathe.
Conduit assemblies (sold separately) protect wiring from coolant and metal chips.
Use a shank (sold separately) to attach a probe to the spindle on your CNC lathe.
