Modular Scanning Coordinate Measurement Machine Probes

Determine a part’s precise shape, position, and size—these Renishaw probes give you comprehensive 3D measurements by continuously gathering data as they move across your part. This means that unlike touch-trigger probes, they can follow the shape of complex features, such as angles and curves. And because they collect more data points than touch-trigger probes, they’re better for engine cylinder bores, dies, and other components that require high accuracy to fit into other parts. These probes are more accurate than other automated measurement systems that use light or cameras instead of touch.

To inspect different features, you can swap them out for a different probe without having to recalibrate. They mount magnetically to a base that threads into your coordinate measuring machine (CMM), making mid-inspection changes quick. They’re also known as modules.

All probes require a stylus, a stylus holder, and a base. Choose a probe based on how long your stylus needs to be. These probes are highly sensitive to length, so you should make sure that the combined length of your holder and stylus falls within the probe’s effective working length range. If you want to use the same probe with multiple styli, you can use multiple holders. However, you can’t mix and match probes with different stylus holders.

Separately

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.

Probe and Base Kits

SF Series—SF series probes have a trigger force that works for most general purpose probing jobs where vibration is not an issue.

TP20 Series—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.

Probe Bases

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 NI Series—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.

Probes

LF Series—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—SF series probes have a trigger force that works for most general purpose probing jobs where vibration is not an issue.

6W Series—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—MF series probes have a slightly higher trigger force than typical applications require to account for vibration.

EF Series—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.

70 mm Long—70 mm long probes are useful if you need to reach deep into holes.

95 mm Long—95 mm long probes are useful if you need to reach deep into holes.

Coordinate Measurement Machine 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.

Probes

Infrared—Infrared probes send data to a receiver up to 5 meters away, but because they use light, they need a clear view.

Radio— 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 Diameter—40 mm probes are typically found in small and medium machines with a chuck size between 6" and 15".

63 mm Diameter—63 mm probes are typically found in medium to large machines with a chuck size between 10" and 24".

Coordinate Measurement Machine 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.
