Blum-Novotest has launched the Z-Nano probe system, a compact tool measuring system that can be used on CNC machining centres to conduct automatic tool-length measurement and breakage detection.

It can also undertake temperature compensation in one machine axis.

A technological advancement over the previous model is an exchangeable measuring surface, which allows a potentially worn or damaged surface to be replaced.

Another improvement is the additional spherical disk in the base.

This enables easy adjustment and setup on the machine table, which is useful for manufacturers loading large billets that could potentially fill the machine bed.

The principle of the linear guide has been implemented to perfection by the engineers of Blum-Novotest.

Instead of the previous sliding guide system, the new Z-Nano works with a ball guideway.

This further reduces the measuring force.

The advantage is that now even smaller tools starting from 0.1mm diameter can be measured, depending on tool geometry and material.

Like all other tactile systems available from Blum, the Z-Nano complies with protection class IP68 and it works with an optoelectronic measuring mechanism.

During the measuring process, the trigger signal is generated by shading a miniature light barrier inside the probe.

This guarantees an absolutely wear-free probe with constant reliability even after millions of operation cycles.

The switching status is indicated via LED and this allows easy control during operation.

Like the previous Z-Nano probe, the system identifies a broken tool to avoid further damage to the work piece or machine tool.

If a tap breaks during threading and the following tap has a collision, the consequences are often damage on the machine and the potentially expensive work piece.

With the Z-Nano such errors are eliminated.

The Z-Nano can be mounted in vertical as well as in horizontal orientations.

Practically proven and optimised measuring cycles for all common control types are included in the delivery program.

For the production of large series runs, time-optimised software is available to enable fast tool breakage detection within one to two seconds.

Accessories wise, Blum offers different mounting sockets with nozzles to clean the measuring surface and the tool.

Also available is a mechanical chip protection system for horizontal mounting.

The probe is delivered with a highly flexible connecting cable and 1.5m of steel mesh.

If installation with cable is not possible, for example, in machines with a pallet changer, the probe is also available without cable and IR transmission.

Blum-Novotest GmbH is recognized as a developer of leading-edge measurement and testing technology, with some 40 years of experience as partner for the worldwide machine tool, automotive and aircraft industries.

The business develops and produces tactile and optical measuring systems for workpiece measurement and tool setting applications in machine tools. Alongside this, Blum develops and manufactures production line integrated measuring and testing solutions.

In addition to the modern, fast growing manufacturing sites near Ravensburg (Germany, BW) and Willich (Germany, NRW) Blum has sales & service subsidiaries in Bordeaux, Como, Birmingham, Cincinnati, Los Angeles, Japan, Taiwan, Korea, Singapore and Shanghai.
