Wholesale Renishaw High Accuracy Probe, Model MP250 Product, Service

The miniature MP250 is the world’s first strain gauge inspection probe for grinding machines, using Renishaw’s patented RENGAGE™ technology. Suitable for use in harsh environments with double diaphragm sealing as standard. It sets new standards for the precision measurement of 3D part geometries, whilst offering all the standard probing benefits of reduced set-up times, reduced scrap and improved process control.

MP250 can also be hard-wired for grinder inspection applications.

Stylus trigger force (notes 2 and 5) XY plane (typical minimum): 0.08 N, 8 gf (0.29 ozf)
+Z direction (typical minimum): 2.60 N, 265 gf (9.35 ozf)
Stylus overtravel force XY plane (typical minimum): 0.70 N, 71 gf (2.52 ozf) (note 3)
+Z direction (typical minimum): 5.00 N, 510 gf (17.98 ozf) (note 4)
Minimum probing speed 3 mm/min (0.12 in/min)

Note 1: Performance specification is tested at a standard test velocity of 480 mm/min (18.9 in/min) with a 35 mm stylus.
Note 2: Trigger force, which is critical in some applications, is the force exerted on the component by the stylus when the probe triggers. The maximum force applied will occur after the trigger point (overtravel). The force value depends on related variables including measuring speed and machine deceleration. RENGAGE equipped probes offer ultra-low trigger forces.
Note 3: Stylus overtravel force in the XY plane occurs 50 μm after the trigger point and rises by 0.12 N/mm, 12 gf/mm (11 ozf/in) until the machine tool stops (in the high force direction).
