Tool Measurement Probes

Tool Measurement Probes

Precise, fast and reliable tool edge verification and measurement for CNC machines in custom and high production machining applications

Z-Axis & 3-Axis Tool Measurement Probes with Sub-Micron Accuracy & Total Reliability

The Blum range of tool measurement touch probes provide simple, robust and highly precise solutions for the purposes of:

  • Broken tool detection
  • Tool length and diameter setting
  • Tool monitoring and wear adjustment
  • Thermal Growth Compensation

To suit different CNC machine sizes and types, probes are available with either direct wired trigger outputs, wireless infrared communications or wireless radio communications.

Z-Nano Length Setting Probe

The simple and robust Z-Nano axial probe is a highly refined solution for precise tool length measurement at a low investment cost.

With IP68 sealing against coolant ingress and highly effective chip protection, the probe has been proven to have excellent reliability in harsh machine environments, in thousands of demanding machine applications.

Suitable for precise tool measurement at a measuring speed of up to 2,000mm/min, the Z-Nano probe allows probing cycles for tool detection and monitoring to be implemented with minimal impact on machine cycle time.

Extraordinary measurement repeatability, down to 0.0002mm, is facilitated by the combination of the probe’s advanced mechanical design, extreme manufacturing precision and Blum’s wear-free optical trigger technology that will maintain this precision even after years of operation.

A low force option allows the probe to be used to measure tool diameters as small as 0.1mm.

A selection of cabled, infrared and radio communication methods provide practical installation options to achieve the ideal probe position in a wide range of machines, including 5-axis applications.

3-Axis Probes for Setting Tool Length and Diameter

The extensive Blum range of tool setting probes meets the needs of many different machining applications. High performance ZX-Speed 3D probes offer full tool length and diameter measurement with excellent precision and reliability.

Extremely compact Z-Pico tool length probes and the modular TC53 and TC63 probing systems efficiently solve high production tool measuring applications.

3D probes with wireless IR and Radio communications allow probe installation on multi-axis machines.
