An unrivalled combination of size

ａnd accuracy

The OMP400 is Renishaw’s new ultra compact probe for small to medium machining

centres, successfully combining the miniaturisation of the popular OMP40 probe, with the

high accuracy strain gauge technology of the MP700.

Utilising the same shank mounting arrangement as the OMP40, this new product gives

existing users a simple upgrade path to the new technology.

The OMP400 probe can be used with either the new OMI-2 or the existing existing receiver

interfaces (OMI, OMM, MI12). The new OMI-2 offers a revised state-of-the-art modulated

optical transmission method which enables the system to offer the highest levels of

resistance to light interference. Compatibility with existing receiver/interfaces allows current

optical system users the opportunity to upgrade to the new probe technology.

By using Renishaw’s proven trigger logic, multiple turn on/off options are available to

optimise the probe for specific machine applications. As always, the probe and interface

are built to the highest of standards and will withstａnd the harshest of machine tool

environments.

The OMP400 offers a truly unrivalled combination of size, accuracy, reliability and

robustness that will benefit its users through reduced set-up times, reduced fixture costs,

reduced scrap and improved process control.

Key benefits

Ultra compact

At only 40 mm in diameter and 50 mm in length, the

OMP400 is the ideal solution for the growing family of small

to medium sized machines that were previously unable to

benefit from the high accuracy of strain gauge performance.

Robust and reliable

The OMP400 sets new standards for reliability and is

designed to resist the harshest machine conditions.

Solid-state strain gauge technology removes the effects

of mechanical wear resulting in up to 10 times the life of

traditional kinematic probes.

Highly repeatable

Strain gauge technology contributes to making OMP400

measurements not only very accurate, but highly

repeatable.

Innovations

Resistance to optical interference

The OMP400 features Renishaw’s new modulated

transmission method, for use with the new OMI-2 receiver,

offering increased resistance to light interference. OMP400

is also backward compatible with existing OMM/MI12 and

OMI receivers.

Extremely accurate strain gauge technology

Using strain gauges, the probe is able to detect lower

contact forces, resulting in less bending of the stylus, less

pre-travel, and greater accuracy. Additional benefits of this

are:

• Increased stylus lengths can be supported without a

decrease in probe performance.

• Excellent 3D performance which allows probing of

contoured surfaces whilst maintaining very high accuracy.
