With robust construction and proven solid-state electronics, the MP250 touch probe is also suited to the harshest of machine environments, said Renishaw.
Using Renishaw's patented Rengage strain gauge technology, the MP250 touch probe is able to achieve far greater levels of accuracy than standard mechanical probes.
The device has sub-micron 3D probe performance on a range of applications that demand high precision measurement, such as contoured surfaces like gear teeth or cutting tools.
This performance is maintained even when the application requires long styli.
The Rengage technology combines a patented sensing mechanism and advanced electronics, giving the MP250 a uniform triggering characteristic in all touch vectors, said Renishaw to manufacturingtalk.
The result is significantly less stylus bending and pre-travel variation when taking measurement points, which gives users improved repeatability and accuracy in all probing directions and reduced probe calibration times compared to standard probes.
Measuring only 25mm diameter x 40 mm long, the MP250 touch probe is ideal for grinding machine applications with restricted space.
It is also specifically designed for use within the harsh environment found in grinding machines, with a body sealed using materials resistant to particle laden coolants and elevated temperatures.
The MP250 has a simple hard-wired connection to the machine control, made possible through the new dedicated HSI interface, which can also be used with standard grinder inspection probes such as the Renishaw LP2.
Despite the use of advanced technologies such as strain gauges, Renishaw said that there is no compromise in overall robustness.
Rengage technology has already been proven in thousands of machine tool inspection applications worldwide, with Renishaw's other high accuracy touch probes such as the MP700 and OMP400.
The MP250 resists shock damage to the same levels as these other market-leading probes, and offers resistance to false triggering through the use of digital filtering. Request a free brochure from Renishaw ...
