Cot Maintenance Machinery

SZ1 HA • Semi-automatic grinding machine (only the loading process is manual)

• Large stone width for perfect grinding results


SZ1 HA • Different holding attachments make this machine suitable for a wide variety of rollers


Variety of roller:

What makes the difference

Small stone width of approx.: 120 mmstone grain: 60-80rpm: max. 900 rpmtraversing: 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. 2.100traversing distance: 16 mmtraversing freq.: 40 times/min

Complete contact of the cot surface to the grinding stone*

Balanced thermal expansion *

Other: Stone Rosink: Stone

*Applies to all Rosink cot grinding machines


Other: Stone Grain Rosink: Stone Gain*

• Rough stone grain of 60 - 80

• 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.


Other: Attachment (Holder) Rosink: Attachment (Holder)

Advanced holding attachments, perfect cylindricity roundness and

perfect balanced grinding results;

no different pressure directions

Centerless grinding (not state of the art);Risk of unbalanced „grinding“ (cutting)

results, due to inadequate bearing surface

Pressure Directions

One Pressure Direction


Individual polishing times guarantee the required RA-values.*

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.*

Short and safe process ways.High process reliability and less risk of faults.*

*Applies to all Rosink cot grinding machines

SZ1 A • Fully automatic grinding of almost all common center guided top rollers• Up to approx. 250 top rollers/hour
