RE: SPM for MG cylinder
Hi vijaydeshin
Just to make sure we all understand, does SPM mean "special purpose machine" or "speed per minute" or something else?

Dear Vijay,
Spray coating (and grinding) of Yankee Dryers (MG, Tissue and SPM) is a tricky business involving hundreds of pitfalls. I know, have been in detail involved in the matter for decades. To try to explain all difficulties on these forum sites would be too boring and voluminous. To even try to give any instructions a lot of basic knowledge about running conditions has to be gathered first.
The first questions would be; what are the dimensions of this cylinder and what is it producing.
What are the quality demands on the produced product, and ????? so on.

PS. May be I misunderstood your question: Do you mean the handling and machining equipment needed for these kind of coating jobs?

RE: SPM for MG cylinder
Hi Vijay
With this type of work, you can not afford to learn by making any mistakes. Companies have gone bust by getting a job like this wrong. I think you really need to employ expert help from people or company that have experience and successful track record in this line of work.
Please see PM.
