DMTS-R is a 3D radio CNC tool setter designed for automatic tool length and diameter measurement on CNC machining centers. It detects tool contact in the ±X, ±Y and +Z directions, enabling compatible CNC measurement cycles to establish tool offsets and perform dimensional checks.

The DMTS-R sends trigger signals using 2.4 GHz radio transmission with smart frequency hopping, avoiding the need for a signal cable connected directly to the tool setter. A 360° transmission envelope and M-code activation support integration with a suitable radio receiver and CNC controller interface.

Specified repeatability is below 1 μm (2σ) at a measuring speed of 30 mm/min. Additional features include a carbide contact pad, IP68 protection, two 14250 lithium batteries and a mechanical trigger life exceeding 10 million cycles.

Qidu provides application assessment, installation guidance and CNC integration support. Receiver compatibility, machine clearance, measurement macros and activation settings should be confirmed before installation.

What is the DMTS-R radio CNC tool setter used for?

The DMTS-R is a 3D contact tool setter designed to support automatic tool length measurement, tool diameter measurement and tool offset verification in CNC machining centers. Its triggering directions allow suitable CNC measurement cycles to approach the contact surface along X, Y and Z axes.
How does the DMTS-R communicate with a CNC machine?

The DMTS-R uses 2.4 GHz radio transmission with smart frequency hopping to send measurement trigger signals to a compatible receiver. The receiver must be integrated with the CNC controller using appropriate signal connections and measurement software.
What is the repeatability of the DMTS-R?

The specified repeatability is below 1 μm (2σ) at a measurement speed of 30 mm/min. Actual measurement performance depends on calibration, tool contact conditions, machine stability and probing procedures.
Can the DMTS-R measure both tool length and diameter?

Yes. The DMTS-R supports ±X, ±Y and +Z triggering, allowing compatible CNC probing cycles to measure tool length and tool diameter or radius. The measurement functions depend on the machine controller and installed macros.
What is the difference between the DMTS-R and DMTS-L?

The primary difference is the signal transmission method. The DMTS-R uses 2.4 GHz radio communication with battery-powered operation, while the DMTS-L uses a wired connection with a normally open contact output. Both support three-directional tool measurement.
How long does the DMTS-R battery last?

The DMTS-R uses two 14250 lithium batteries. The manufacturer's specification indicates standby battery life exceeding 300 days, with more than 260 days at 3,000 triggering operations per day under stated conditions. Actual battery life varies with usage.
Does the DMTS-R require a radio receiver?

The radio transmission system requires a compatible receiver to communicate measurement signals to the CNC control system. The specific receiver model, wiring requirements and supplied package contents should be confirmed before ordering.
Can the DMTS-R be integrated with FANUC or Siemens controllers?

Qidu provides CNC integration support for major controller platforms, including FANUC and Siemens. Compatibility with the DMTS-R requires verification of the specific controller, receiver interface, M-code activation and measurement macros.
