NC4 non-contact tool setter

High-precision, high-speed, non-contact tool measuring and broken tool detection on all sizes of vertical and horizontal machining centres, multi-tasking machines and all gantry machining centres.

Rapid on-machine tool setting and broken tool detection

Robust performance in harsh machining environments

Flexible non-contact tool setting solutions

Increase productivity

Automatic tool setting with the NC4 gives your machine tools the intelligence they need to make decisions for themselves, enabling ‘lights out' machining.

Increase productivity

Highly flexible

A host of system options and configurations makes the NC4 the most flexible non-contact tool setting solution on the market.

NC4 system options

Reduce scrap

The NC4 measures and detects tools down to Ø0.03 mm and to a repeatability of ±1.0 μm (2σ) – ensuring the production of ‘right first time' parts.

Reduce scrap

Reliable operation

The NC4's integrated air blast and dual measurement mode, delivers accurate and robust performance in even the harshest machining environments.

Enhanced NC4


Install, configure, use and maintain the NC4 with ease thanks to our comprehensive range of smartphone and on-machine apps.

If it wasn't for the Renishaw system, the machine could, for example, operate with a broken cutting tip, with disastrous results. Furthermore, since tools are checked for breakage automatically, one operator can easily manage both machines: all he needs to do is load the pieces and ensure that everything is running smoothly.
