Speeds below 3 mm/min commonly occur when manually moving the probe using the handwheel with a very fine
feedrate.
2
Performance specification is tested at a standard test velocity of 240 mm/min (9.45 in/min) with a 50 mm (1.97 in)
carbon fibre stylus. Significantly higher velocity is possible depending on application requirements.
3
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, machine deceleration and latency.
RENGAGE equipped probes offer ultra-low trigger forces.
4
These are the factory settings; manual adjustment is not possible.
5
Stylus overtravel force in the XY plane occurs 70 μm (2755.91 µin) after the trigger point and rises by 0.1 N/mm,
10 gf/mm (9.1 ozf/in) until the machine tool stops (in the high force direction and using a 50 mm (1.97 in) carbon
fibre stylus).
6
Stylus overtravel force in +Z direction occurs 1.0 μm (39.37 μin) after the trigger point and rises by 0.6 N/mm,
61 gf/mm (54.8 oz/in) until the machine tool stops.
