I am working on a project milling a 2" thick
piece of PVC. MSC and Enco sell it.
I notice the small chips when fall onto a ground surface leave a brownish stain on the cast iron table also same stain appears on the ground diameters of end mill holders.
Any of you had the same experience ???????

Thanks Graeme

Absoutely, the material is very corrosive.
We did several large jobs for a local company with it. Used alot of WD-40 and scotch brite to keep the finer equiptment from rusting.

Be careful of the fumes from PVC. Nasty stuff. Causes tumors. Not the risk of tumors, but simply put CAUSES tumors. It was a company secret that the petrochemical people kept from telling the workers for many years even while they shared their secret with their overseas affiliates. Corporations just don't care squat about the working man.

It still isn't well known to the public. Be careful of the fumes.

Poly Vinyl Chloride,it's the chloride that causes the corrosion.
Vinyl Chloride is what caused the plant workers finger bones to dissolve inside thier fingers,but that was from prolonged exposure while cleaning equipment without gloves.
I wouldn't worry too much,after all,it's what every once of water we drink,bath and wash clothes in is piped through http://bbs.homeshopmachinist.net//rolleyes.gif
