Features:
Easy operation and versatility, combined with the computer
to provide fast and results. The analyzer will compute four
reference circles (the minimum zone, least squares, circumscribed
and inscribed ), the out-of-roundness and eccentricity value
relative to any of the four references are presented both
quickly and reliable. The instrument is designed with compact
structure, portability and convenient maintenance. It is yet
shockproof so as to suit workshops.

Correction sphere |
Correction
sphere
It is a glass semisphere lapped with accuracy ¡À0.025mm, for
verifying the radial accurcy of rotary table. |
Precision rotary table |
Precision rotary table
Precision rotary table Its diameter is 200mm, and the max. load
for part reaches 10 kg. A precision spindle is mounted on low
end of the rotary table. The speed of the table is 2.5 rps.
There are two knobs spaced 90¡Þ on the table. they can adjust
declination for table surface. Adjustable range is ¡À2 rev.
(approx. Adjustable range is ¡À2 rev. (approx. ¡À40¡¯). |
Column |
Column
The sliding bracket is installed on the column. By turning knob,
the bracket can move along column up or down, also can be fixed
with the lock handle. A scale which shows moving height is mounted
on the column, the full displacement is 250mm. |
 Pick-up
|
Pick-up
This is a side-measuring electroinduction pick-up. It can be
mounted vertically or horizontally. In order to measure various
shape, the stylus arm can be turned to certain position on measured
surface easily. After mounting stylus stop attachment interrupted
surface can be measured. |
÷ Recorder(YD200A) |
Recorder
The profile of measured part and relative reference circle are
recorded on the polar Chart in diameter 150mm. The width of
the recording zone is 40mm. The chart rotation is synchronous
with spindle. |
