OMP400 Compact high accuracy touch probe RENISHAW

OMP400

The OMP400 is an ultra compact probe, ideally suited to small to medium machining centres. It combines the miniaturisation of the highly successful OMP40 probe with new advances in strain gauge technology, pioneered by Renishaw's high accuracy MP700 probe.

Strain gauges attached to the structure measure the smallest of stylus motions, allowing for a very sensitive system.

The innovative RENGAGE™ technology built into the OMP400 brings unrivalled performance in terms of 3D measurement. Use OMP400 with Renishaw OMV for advanced on-machine verification when machining contoured surfaces and complex shapes.

* Performance specification is for a test velocity of 240 mm/min (9.45 in/min) with a 50 mm carbon fibre stylus. Test velocity does not constrain performance in application.

** The stylus trigger force is the force exerted on the component when the probe triggers. However, the maximum force applied to the component will occur after the trigger point and will be greater than the trigger force. The magnitude depends on a number of factors affecting probe overtravel including
measuring speed and machine deceleration. If the forces applied to the component are critical, contact Renishaw for further information.

§ Stylus overtravel force in XY plane occurs 70 µm after the trigger point and rises by 0.1 N/mm, 10 gf/mm (9.1 oz/in) until the machine tool stops (in the high force direction and using a 50 mm carbon fibre stylus).

† Stylus overtravel force in + Z direction occurs 10 to 11 µm after the trigger point and rises by 1.2 N/mm, 122 gf/mm (109.6 oz/in) until the machine tool stops.
