The Metrotom 1 is a
Metrology grade CT scanner
that is provided by Zeiss and Central
Scanning our hands on Metrology
partners with Zeiss.
We both sell the system and will deliver
and train you on the system.
CT scanning
is a process of using X-rays
to take 2D images.
X-rays allow us to see an image
with the density across the material,
and then the part will turn
inside the CT scanner.
Taking multiple shots.
Creating lots of 2D images
as the part rotates.
This allows us to then reconstruct
the 3D shape of the part.
Both the outside
and insides of outline of sight,
by comparing the different densities
across the images,
making us a 3D model
known as a volume, which we can
then process as a mesh.
And from here
we can start inspecting it
both visually and physically,
measuring it against
drawing and inspection standards.
So the Metrotom 1
is able to scan in a 165
by 140 millimetre area.
It also has a higher resolution of 80
by 80,
with a 32 micron resolution
or a 64 micron resolution.
It's Metrology grade,
meaning it's
got a certified accuracy of down
to five microns
plus length of the part
divided by a hundred.
And it's able to see inside parts
and outside parts
without having to cut them
or destructively test them.
The scanner typically takes
anywhere between
about 15 to 25 minutes for most parts,
especially if they're plastic.
But if they're metal parts,
they can take upwards of more around
an hour to two hours.
The amount of parts
you can put in one go is dependent
on the volume of the area.
So our volume is 165 millimetres by 140,
meaning as long as we can fit
all of our parts in there
and keep them still, we can scan them.
This means if I've got a big part,
I could only probably scan one.
But if I've got lots of small plastic parts
I could scan maybe 40 or 50 all at once.
Any material can work in there,
It's basically around the density,
so it's a bit more
to do with the thickness.
So typically we say
it can scan up to aluminium parts.
It's definitely
can scan all plastic parts
when it comes to more dense materials
like steel,
you're looking at only being able
to scan stuff thatβs small
with only a couple millimetres
of wall thickness,
but it's kind of test it as you go.
Mostly plastics, definitely aluminium.
So the main difference is
to do with the word Metro.
So Metro stands for Metrology
which means it has metro tomograph
which is the type of X-ray being used.
This is effectively
a certified accredited accuracy.
So it's certified
under VDI and VD standard
from Germany
uses DACS certified sphere
artifacts to be scanning,
which means when we scan anything,
we actually have an accuracy
of our measurement,
which is five microns
plus the length of the part
divided by 100.
While most other scanners
are only for visual inspection,
so you can't actually measure the data
that you capture.
So the biggest improvement is
we don't need
to rely on visual line of sight
because it's using x rays
we can see into parts.
This means that we have cavities, holes
and so on, we can see into them.
We can also outline defects.
There's things like voids
or gaps inside parts
that can cause structural failure.
And all of this can be done
without having to cut
or destroy the part.
The other side is we can scan
lots of objects all at once
if they're small enough,
so we don't have to just be scanning
one thing at a time.
So Zeiss
X-ray is a pivotal part of our system.
It comes with the hardware itself,
and it basically allows us
to not
only process
the scan data
and make it into STLβs or meshes,
but also allows us to inspect it
because it's being a Zeiss
inspect software.
This means we can set up
reproducible templates and reports
for inspection and quality control.
Checking against the dimensions,
the drawings, the GD and T,
and then inspect our parts in batch
line processing so that we can check
if they pass the quality control.
Central Scanning
do offer
training for sales of this equipment.
We basically offer
classroom style training,
which will basically train you
on the acquisition,
how to use the scanner,
how to capture data, how to scan parts.
We also offer
e-learning material as well,
both through the YouTube
and also through paid e-learning content
that you can get certified on.
So we offer service scanning.
We actually have offered
service scanning
for CT
scanning data for a while,
so weβre quite experienced with it.
We can basically ask you
to send your parts
along with the drawings and the details
on what you want us to measure as well.
And we can basically CT
scan them, check them for voids,
check them for measurements,
provide you with inspection reports.
We can do batch line inspection
and typically
itβs based around your parts
and how many you want us to scan.
