RT800 Roundness Measurement

Product Details

High speed roundness systems for bearings, automotive and
precision industries

A range of roundness products robust enough for the shop floor
but accurate enough for any inspection room.

Working closely with manufacturers across a wide range of
industries including bearings, automotive and aerospace
engineering we have focused on the key attributes that are most
important for quality control in today’s precision

The new Starrett RT800 offers a flexible solution for all your
roundness and form requirements with a variety of systems and
application specific accessories along with fixtures that can be
tailored to your specific need.

Speed (3 parts/minute including set-up)Rt800 Touch Screen

The most important benefit these systems offer is speed. In
precision industries as manufacturing volumes increase all too
often the bottleneck is metrology. High measurement throughput
systems ensure higher sampling rates are achieved while also
supporting increased manufacturing volumes.

Precision (±25 nm spindle accuracy)

Although many times faster than traditional benchtop roundness
systems there is no loss of precision or accuracy. Full ISO
compliant measurements can be taken with ±25 nm accuracy
and 30 nm gauge resolution.

Robustness (suitable for 24/7 operation)

All systems are designed for constant 24 hour, 7 days a week use
in demanding shop floor environments; manufactured using only the
most durable and hard wearing materials.

Ease of use (touchscreen software)

The X-sight touch screen software platform with intuitive
navigation make the RT800 roundness system as easy to use as a
SatNav or SmartPhone with everything you need at your fingertips.

What can it measure?

Measurement ExampleThe
Starrett RT800 is ideal for measuring high volume production
parts across a wide variety of industries including:

  • Bearings – Races, Balls, Needles and
  • Automotive – Valves, Con Rods, Pins and
    Brake Discs
  • Process Control – Grinding, Turning,
    Milling and Honing

and many more…

Patented gage orientation

Using a patented gage orientation with its robust locking
mechanism changing orientation from roundness to flatness or
internal to external only takes a few seconds.

Accurate gaging

All systems incorporate an accurate and reliable Talymin gauge
technology, delivering 6 nm resolution.

Patented Rapid CenterTM

Rapid Center avoids valuable cycle time being lost on manual part
centering. On most parts precision results are achieved following
a very simple and fast loading procedure. Now roundness
measurements can be made in less than 30 seconds including part
loading, centering, measurement, analysis and results display!

Accessories and standards

A full range of accessories and standards are available to
support the instrument. These include Magnetic chuck, Rapid
Center fixture, Glass hemisphere, Calibration set, Precision test
cylinder, Cresting standard, Stylus kit, Flick standard (20 μm
or 300 μm) and replacement air filter modules.
