Renishaw has expanded its range of radio transmission probe systems with two products: an interface that allows multiple probe installations on the same machine tool; and a compact tool-setting probe with radio transmission that is suitable for larger machines.

The RMI-Q radio transmission interface allows up to four separate tool-setting or spindle probes with radio transmission to be operated on the same CNC machine, making it suitable for fitment onto CNC machining centres or machines with rotary tables or twin pallets.

The system is designed for applications that have obscured line of sight between the probe and the receiver, and its transmission range of up to 15m makes it particularly suitable for large machines.

The RTS contact tool setter can compensate for variation during the machining process and update the controller automatically to account for actual effects, such as tool wear. It also allows processes to be automatically stopped when broken tools are detected. This reduces rework, re-makes, concessions and scrap.

Products in detail

RMI-Q radio transmission interface

  • This is easily integrated on a wide range of machining centres and CNC milling machines, enabling users to enjoy all the benefits of Renishaw probe systems, including cable-free automated on-machine tool setting, tool breakage detection, part setup and part verification capability.
  • Numerous multiple-probing configurations are possible, typically comprising the new Renishaw RTS tool setter with RMP60 inspection probe or other compatible spindle-mounted touch probes with radio transmission such as RMP40 or RMP600, selected to suit the user’s specific application requirements.
  • The RMI-Q is used to activate either the spindle-mounted touch probe or table-mounted tool-setting probe and gives visual indication of the activated device.
  • It features the 2.4GHz frequency hopping spread spectrum (FHSS) radio transmission, designed to be compliant with radio regulations worldwide, which enables uninterrupted operation in increasingly busy radio environments.
  • The RMI-Q has all the functionality of Renishaw’s RMI interface, plus additional features including the ability via a simple macro to partner all required probes to the interface in a single operation.

RTS contact tool-setting probe

  • This robust, compact and cable-free tool-setting probe does not restrict table movement.
  • Signals from the probe are communicated using radio transmission, which makes it suitable for machines of any size, for machines where line of sight is an issue and for machines with twin pallets or rotary tables, which can be challenging for installations of hard-wired tool setters.
  • Powered by two standard AA batteries and benefiting from significantly extended battery life, the RTS can be used in conjunction with up to three other radio probes using the new RMI-Q product.
