A range of non-contact tool setting and broken tool detection systems for machining centres.

Available in separate (modular) and fixed (compact) formats to suit a range of machine configurations.

About NC4

The NC4 allows fast, non-contact tool setting and tool breakage detection on a variety of machining centres. Available as fixed system and separate system variants, the NC4 incorporates the unique MicroHole™ protection system and the innovative failsafe PassiveSeal™, maintaining IPX8 environmental protection.


Recently introduced to the fixed NC4 range are the F95, F115 and F230 compact series, offering new performance standards in small packages, using the same transmitter and receiver units as the NC4 separate and modular fixed systems.

With all NC4 systems, precision optics are supplied as standard. These enable the compact series to achieve un-surpassed performance in a unit particularly suited to small machines and machines where space is at a premium.

NC4 features and benefits

  • Compact design is ideal for machines previously unsuitable for large non-contact systems
  • Precise tool length and tool diameter measurement
  • Only 1 M-code required
  • NC4 measures and detects tools of ø 0.03 mm or larger (dependent on separation and mounting)
