10. SZ1 HA Cot Maintenance Machinery Semi-automatic grinding machine (only
the loading process is
manual)
Large stone width for
perfect grinding results

11. SZ1 HA Cot Maintenance Machinery Different holding
Variety of roller:
SZ1 HA
Different holding
attachments make this
machine suitable for a
wide variety of rollers

12. What makes the difference
Other: Stone
Rosink: Stone
Small stone width of approx.: 120 mm
stone grain: 60-80
rpm: max. 900 rpm
traversing: no
Small contact surface. Grinding stone cuts into the rubber, instead of grinding it.
Unbalanced thermal expansion. Results in: unbalanced grinding results and shorter lifetime of the cot
width: 410 mm, grain: 120
rpm: max
traversing distance: 16 mm
traversing freq.: 40 times/min
Complete contact
of the cot surface to the grinding stone*
Balanced thermal expansion *
*Applies to all Rosink cot grinding machines

13. What makes the difference
Other: Stone Grain
Rosink: Stone Gain*
Rough stone grain of
Stone grain of 120
Results into homogeneous roller surface quality
Coarse stone grinding results in insufficient surface smoothness
In 99% of the cases no need for additional treatment like UV / ACID
All Rosink cot grinding machines are using the same stone grain.

14. What makes the difference
Other: Attachment (Holder)
Rosink: Attachment (Holder)
Centerless grinding (not state of the art);
Risk of unbalanced „grinding“ (cutting) results, due to inadequate bearing surface
Advanced holding attachments, perfect cylindricity roundness and
perfect balanced grinding results;
no different pressure directions
Pressure Directions
One Pressure Direction

15. What makes the difference
The stone is traversing (approx. 16mm at 40RPM), not the roller. This ensures the high quality of the grinding and polishing results (RA-Values).*
Depending on the hardness and type of roller you can set the appropriate grinding time.*
Individual polishing times guarantee the required RA-values.*
Short and safe process ways.
High process reliability and less risk of faults.*
*Applies to all Rosink cot grinding machines
