Swap out Renishaw probe styles to inspect different features on a part without having to recalibrate. These probes mount magnetically to a base that threads into your coordinate measuring machine (CMM), making mid-inspection changes quick. They’re also known as modules. It’s easy to tell different styles apart from their different end colors. To take 3D measurements, they record the coordinates of different points on your workpiece. Because this involves physically touching your workpiece, they’re more accurate than other automated measurement systems. They’re touch-trigger probes, the most common CMM probe type, which means they stop to record the coordinates of one point at a time. Use them to check distances, diameters, right angles, and the location of holes and grooves. However, they're not as good at checking complex features, flatness, or roundness.

All probes require a stylus as well as a base (sold separately for some probes).

Trigger force is the amount of force required for a probe to take a measurement and record it. Choose a probe with a force that is high enough to avoid false triggers from vibration but not so high it damages the workpiece and leads to inaccurate measurements.

LF series probes have the lowest trigger force, so they’re best on materials such as rubber that could be deformed by too much pressure from probing. However, they’re the most likely to accidentally trigger from vibration.

SF series probes have a trigger force that works for most general purpose probing jobs where vibration is not an issue. 70 mm long and 95 mm long probes are useful if you need to reach deep into holes.

6W series probes work well if you need to inspect features on the bottom of a part, such as overhangs and undercuts. They measure in six directions instead of five.

MF series probes have a slightly higher trigger force than typical applications require to account for vibration.

EF series probes have the highest trigger force, so they’re the best choice for environments with vibration. They also work well for larger styli, such as long 5-star styli.

Bases house the system that sends a signal to record a measurement. They thread onto probe heads with an M8 connection on your CMM. TP20 probe bases have a magnetic proximity switch to prevent a probe from accidentally triggering when you’re attaching it or detaching it. However, probes attached to these bases can’t be used to inspect magnetic parts. TP20 NI probe bases aren’t affected by magnetic fields, so they can be used to inspect magnetic parts. However, because they don’t have a magnetic proximity switch, you’ll need to program your CMM to stop taking measurements when you’re changing out probes.

Installation tools make it easier to thread a probe base onto your CMM.

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. Radio probes send data to a receiver up to 15 meters away. They block out interference from other radio devices, so you can use multiple radio probes in one machine shop.

40 mm probes are typically found in small and medium machines with a chuck size between 6" and 15". 63 mm probes are typically found in medium to large machines with a chuck size between 10" and 24".

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.
