1-2 Regular inspection and maintenance
Critical points in a principle of polishing withSFP-550 Polishing Machine are
following:
1. Polishing track of ferrule by revolution and rotation of the turntable
2. Pressure of polishing (the space between the clamping postson the
four corners and the turntable, the protrusion length of ferrules from the
bottom side of the polishing holder)
Read and familiarize yourself with the followings before inspection.
1-2-1 Grease check in the drive unit (once a month or for every100-500 driving
hours)
Remove the turntable and check the drive unit if it is full up with grease.
See Figure 1-2-1.
1-2-2 Dimension check for the turntable and others (once for 3 months or for
500-1000 driving hours)
Check the space between the clamping posts on the four corners and the turntable.
••The space between each clamping post and the turntable: 5.5•
•0.02mm
See Figure 1-2-2.
1-2-3 Pressurizing unit check (once for 6 months or for every1000-2000 driving
hours)
Check the free length of the pressurizing coil springs installed in the clamping posts.
••The free length of the pressurizing coil springs (P/N: RP55-20): 14•
•1mm

specification value, in accordance with the following procedure.
Loosen the set screws on the side of the base plate (two screws for each clamping
post).
−
−
−
−
Remove the clamping post (pressurizing) unit and spacer.
Measure the thickness of the spacer, t.
Calculate the required thickness of the spacer, with the former measurement result
of the spacer, t, in accordance with the following expression.
Required thickness of the spacer ••Space between the turntable and
clamping post + the thickness of the present spacer, t
Example:
Space between the turntable and clamping post: 4-scale to minus (-0.04mm)
and the thickness of the present spacer, t: 3.00mm, then
Required thickness of the spacer = (-0.04mm) + 3.00mm = 2.96mm
Repeat this procedure for all four clamping postseach.
When you order the spacer (RP55-16), please designate the thickness of the
spacer.
