DTS500 is a wired Z-axis contact tool setter designed for automatic tool length measurement and offset setting on CNC machining centers. Its Ø50 mm tungsten carbide contact pad detects tool contact along the +Z direction, providing a trigger signal to a compatible CNC controller through a normally open (NO) output.

The DTS500 specifies repeatability below 1 μm (2σ) at a probing speed of 50 mm/min. A 0.7 mm pre-stroke, 11 mm axial stroke and 5.5 mm trigger protection distance define the published contact movement characteristics. The unit also features IP68 sealing and a 5 m oil-resistant, six-core cable for wired integration.

Its larger contact pad offers a distinct option within Qidu’s Z-axis tool setter range, although tool compatibility depends on geometry and measurement approach. With appropriate controller inputs and macros, the DTS500 can support tool length verification and basic breakage checks. Qidu provides assistance with mounting, wiring, calibration and machine integration.

What is the DTS500 CNC tool setter used for?

The DTS500 is a Z-axis contact tool setter designed for automatic tool length measurement, tool offset setting and programmed tool length verification on CNC machining centers. With suitable measurement macros, it can also support basic tool breakage checks.
What is the contact pad diameter of the DTS500?

The DTS500 features a 50 mm diameter tungsten carbide contact pad. This provides a larger contact surface than the DTS100 and DTS200 models, although suitability depends on the cutting tool geometry and measuring approach.
What is the repeatability of the DTS500?

The DTS500 provides specified repeatability below 1 μm (2σ) at a measurement speed of 50 mm/min. This represents measurement consistency under the stated conditions and should not be confused with absolute measurement accuracy.
What is the difference between DTS500 and DTS200?

Both are Z-axis contact CNC tool setters with normally open outputs, 11 mm axial strokes and specified repeatability below 1 μm (2σ) at 50 mm/min.

The primary differences are their contact pad diameters and physical dimensions. The DTS500 uses a 50 mm contact pad, while the DTS200 uses a 20 mm contact pad.
Can the DTS500 measure tool diameter?

The DTS500 is specified for +Z triggering and is primarily intended for tool length measurement. It is not a multidirectional tool setter for direct X/Y contact measurement.

For applications requiring both tool length and diameter measurement, Qidu offers 3D tool setters such as the DMTS-L and DMTS-R.
How does the DTS500 connect to a CNC controller?

The DTS500 uses a six-core wired connection with a normally open (NO) contact output. Its specified contact rating is DC 24 V at a maximum of 20 mA for a resistive load, with 10 mA recommended. The electrical interface and wiring must be verified for the particular CNC controller.
Can the DTS500 detect broken cutting tools?

Yes, when integrated with suitable CNC measurement programs. A programmed length check can compare the measured tool length against a reference value to help detect significant changes caused by tool breakage.
What is the axial stroke of the DTS500?

The DTS500 has a specified Z-axis stroke of 11 mm, a pre-stroke of 0.7 mm and a trigger protection distance of 5.5 mm. These values should be considered when planning the tool approach, probing speed and safe machine clearance.
Does the DTS500 support air cleaning?

The supplied product photographs show a pneumatic connection and an air nozzle arrangement. However, the technical data does not specify the required air pressure or establish whether all air-cleaning accessories are supplied as standard. These details should be confirmed before installation.
Is the DTS500 compatible with FANUC or Siemens CNC machines?

Qidu provides CNC integration support for major control platforms, including FANUC and Siemens. Compatibility with the DTS500 depends on the specific controller model, available probe inputs, electrical configuration, measurement macros and installation requirements.
