OPTICAL MANUFACTURING

rnAMOS has an optical workshop for mirror fabrication up to 3 m diameter rnand the necessary metrology equipment for optics qualification.

This workshop includes mainly:

a lightweighting machine;
grinding and polishing machines;
Computer Controlled Polishing Machines;
anrninterferometry test tower (12 m height) with a movable platform rnequipped with a ZEISS interferometer DIRECT 100 and a holographic testrnbench
vacuum chamber for ion beam figuring
MOORE ultra-precision diamond turning lathe and freeform generator
5-axis CNC high accuracy milling center

MECHANICAL MANUFACTURING

We have a number of vertical lathes, boring and drilling machines, machining centres, plane grinding machines, ...

CONTROL SUPPORT

rnAt all steps of the manufacture, parts are tested in order to warrant rnquality and compliance with specifications. Our factory rninspectors use :

Welding :

Gauge testing bench
Instruments for non destructive testing : X-Rays, ultrasonic (Krautkrammer),electromagnetic, fluorescent dye penetrant.

Metrology :

Profile Projector NIKON R14
Electronic level TESA
Level WILD N3
Theodolite WILD T2
Telescope TAYLOR-HOBSON
Roughnessmeter DIALITE MT 10
Optimeter KARL ZEISS
INVAR rulers
LASER TRACKER

rnThe laser tracker is a versatile measurement instrument making possible rn3D dimensional control and alignment from 0 to 35 m with an accuracy uprnto 0.03 mm. The associated software allow to fit the measurementsrnwith any kind of geometrical entity and even directly with the CAD rnmodel. The geometrical tolerances and other dimensions can be rncalculated instantaneously and the test report issued directly.

3D measuring machine (Co-ordinate Measuring Machine) - WENZEL

type : LH64
Measuring Range : 650x1200x500 mm
accuracy : U1=2.5+(L/300) mm
U2=3.5+(L/200) mm
CNC operation.
Software : Metrosoft

The CMM can be used for dimensional AND figuring error control of mechanical parts.
Test reports can be edited using ISO1101 protocol.
rnThanks to CNC operation allowing iterative measurements, CMM can be rnused for mechanical alignment purpose. This machine will bernused during all the AIV operations of the three models of the Grating rnDrive Mechanism.
