your copy of the booklet
obtained a copy of my own
returning yours herewith. I will suggest to STATINTL
that he get a copy. Note on pages 149 and 150
net tne measuring engine'structure of the Alkwi is made
of special aluminum castings stabilized and tempered. STATINTL
Also, the carriage moves on ball?beari
supports.- The comment is made
Structure has remained unchanged throughr -models STATINTL
and is considered to be stable and accurate. This
reinforces my opinion that the mechanical geometrical
design of the engine is of aqua tance to the
stability of the materials used paid particular
attention to compensating for therma ezpenston of STATINTL
the metals used.
n tubular STATINTL
het the
ificant factor to constder is that was STATINTL
for + 2 micron accuracy while the pEasolver
ng fFr less than 1 micron accuracy. I am sure
get submicron measuring accuracy, as much
on must be paid to the structure as was paid
measuring device.
