Renishaw introduced recently the world’s smallest wireless probe for machine tools
Global engineering technologies company, Renishaw, showcased its latest radio transmission probing system at EMO Hannover 2023.
The RMP24-micro is the smallest wireless machine tool probe on the market, measuring just 24 mm in diameter and 31.4 mm in length. As well as its miniature size, the RMP24-micro also delivers market-leading metrology performance for a wireless probe in this size category. With measurement repeatability of 0.35 micron 2σ and low trigger forces, it is ideally suited to compact machines manufacturing high-value, high-precision components, such as those found in the medical, watchmaking and micro-mechanics industries.
RMP24-micro utilises Renishaw's updated radio transmission protocol to communicate with the machine tool controller – via the RMI-QE radio interface. With an operating range of up to 5 metres, it employs a 2.4 GHz frequency hopping spread spectrum (FHSS) protocol, which is industry-proven and compliant with radio regulations worldwide. FHSS technology enables both the probe and interface to jump from channel-to-channel while maintaining communication, allowing the probing system to operate alongside other radio sources such as Wi-Fi, Bluetooth® and microwaves. This is not the case for other protocols which may require manual intervention to operate in the same environment.
