Mitutoyo’s new CMM range offers
superior performance
»
Mitutoyo’s new generation CRYSTA-Apex V CNC CMM delivers advances in accuracy, speed and versatility
across a 10-model range, spanning applications from the small to mid-sized part range.
The company says that the performance specification is unmatched by any previous CMM of this class
through features that include an advanced real-time thermal compensation system that makes accurate
measurement possible in environments with varying temperature.
Unlike earlier generation CMMs, a controlled environment is unnecessary and the CRYSTA-Apex V
Series maintains high accuracy over the temperature range 16-26°C to allow automation of in-line and
line-side measurements within the manufacturing process,
significantly reducing measurement times and streamlining the
workflow.
An active scanning feature enables high speed measurement
by tolerating discrepancies between design values and actual
workpiece dimensions while maintaining the advantages of 3D
optimal-path scanning. The intricacies of some workpieces,
such as turbine blades and impellers, causes their accuracy to
vary or makes them more susceptible to misalignment, causing
measurement to be difficult, but the V Series enables smooth
measurement of this type of complex workpiece.
Higher maximum drive speed and acceleration of around
20% and 40% respectively, compared
with conventional CNC CMMs, enables
the V Series to operate substantially
faster, resulting in about 100 mm
more traverse distance one second
after starting movement. This faster
movement combined with typically
60% higher measuring speed cuts total
inspection time significantly and the
advantage increases with the number
of features measured on a part.
The V Series also features
Mitutoyo’s Quick Launch function
that enables
simple and
intuitive
operation
for easy
part-program
execution,
including via
barcodes and
QR codes,
making
operation
effortless for
anyone.

Sanitised materials
fight bacteria
»
Every day people move from one place to another.
While doing so, they touch and contaminate a variety
of surfaces which means that bacteria and germs
are spread and can be transmitted to other people.
Bacteria are everywhere. Some of them, like those in our
intestines, on our skin or in yoghurt, are healthy and
useful. The wrong kind, for example pathogenic bacteria,
or in the wrong place, they can make people ill.
PA-Sanitized (sanitized polyamide) was developed
to prevent bacterial growth on components made of
these products. In tests carried out according to the
standard JIS Z 2801:2010 for antibacterial products,
it was seen that bacterial growth on the surface of
products made using sanitized material was reduced
by more than 99%. This means that antibacterial
conditions exist on the surface of the material
preventing propagation of the bacteria.
Application areas for this kind of material are
found, for example, in the field of medicine, in public
transport systems for handrails and handles, in an office
environment for keyboards and telephones or in the
automotive industry for door openers, buttons and keys.
Sanitized polyamide materials have been developed
by EMS for the following product families, where use
can be made of the benefits provided by the basic
polyamide. The product families are characterised in
each case by the following three core properties:
• GRIVORY GV: high stiffness and strength, low uptake
of moisture or water, high ductility
• GRIVORY HT: high stiffness and strength at high
application temperatures, low uptake of moisture or
water, high resistance to hydrolysis
• GRILAMID L: low water uptake, resistance to
chemicals and weathering, high impact strength –
even at low temperatures
• GRILAMID TR: crystal-clear transparency, high
resistance to chemicals, contains no bisphenol-A (BPA)
