Hard Chrome Plating (Technology from German Consultant)
We have over 35 years of extensive experience
in Hard Chrome Plating Rolls of various sizes and base
materials.
We specialize in Hard Chrome Plating
1) Dryer Cylinders
2) Chilled Cast Iron Calendar Rolls
3) Applicator Rolls / Take off Rolls/ Felt Rolls etc.
We can Hard Chrome Plate Upto
:-
- 1524mmØ x 2000mm L or
- 900mm Ø x 6000mm L or
- 200mmØ x 10000mm L,
- 10 tons weight capacity
We can hard chrome plate the following
base material
1) Cast Iron
2) Chilled Cast Iron
3) Stainless Steels
4) Mild Steel
5) Hardened Steels
6) Copper
7) Nickel
8) Brass
9) Bronze
Major advantage of Hard Chrome Plating
are :-
1) Hardness without distortion of the
work piece.
2) Wear Resistance
3) Corrosion Resistance
4) Low Co-efficiency of friction
5) Anti adhesive behavior
6) Resistance to most chemical corrosion
7) No tarnishing or oxidation at high temperature
Roll Grinding
We have 15 years of extensive experience
in grinding Rolls of various sizes and base materials.
We have high precision German Roll Grinding and Cylindrical
Grinding machines (Waldrich, Naxous Union), the above
coupled with precision Measuring Instruments, well designed
support systems for jobs,
and skilled operators, enable us to deliver jobs to very
close geometric accuracies.
We can grind upto:-
1850mmØ x 6500mm L or
250mm Ø 10000mm L or
25 tons weight capacity
Geometric Accuracies :-
1) Concentricity : Less than 3 micron
(Depends on Roller Construction)
2) Cylindricity : Less than 3 micron
(Depends on Roller construction)
3) Taper : Less than 2-3 micron per
meter
(Depends on Roller construction)
4) Camber Profile : 2-3 micron station
to station variation.
We specialize in grinding Calender Rolls
to very close Geometric tolerances and good surface finish,
resulting in tight control on gauge variation of paper
being manufactured and also gloss imparted to the paper.
We can also carry out repair of broken
journal/side shaft of Calender Rolls.
With an infrastructure of 3 Roll Grinding and 5 Cylindrical
Grinding Machines, we can meet very short delivery times
to minimize your shut down time.
Super Finishing
We have high precision German Super
Finishing Machines to achieve high gloss
mirror finish, subsequent to the grinding operation. We
use special abrasive tools to reduce peak to valley height
and impart High Gloss Mirror Finish to the Roll resulting
in a surface finish of 0.005 micron Ra Value on the Roll.
Rolls Manufacturing
We have a special infrastructure for
fabrication of Single / Double Jacket Rolls in Mirror
Finish/ Matt Finish for various applications ranging from
Heating / Cooling / Coating / Lamination/ Calendering
etc.
For Heating / Cooling Rolls our special
internal construction ensures very low temperature gradient
across the entire barrel length of the Roll, resulting
in uniform quality and thickness of Sheet/ film passing
between the Rolls.
We use special manufacturing techniques
to ensure that the fabricated Rolls are dynamically balanced
to close tolerances, resulting in vibration free running.
We put at your disposal all the experience
we have gained, our precision infrastructure of high quality
Grinding Machines, Hard Chrome Plating, Super Finishing
Machines and precision Measuring Instruments, our technical
team which is ever eager to interact closely with you
to work out the best solution suited to your technical
requirements.
