Fabricating Data

Paper And Fabric Grades


Ordinary high-speed tool steel can be used in finishing operations for all Atlas Fibre grades.  However, carbide-tipped tools will prove more economical and will hold sizes more accurately from piece to piece.  About .010” stock should be left for finishing.  Our Laminates can be turned at 400 surface feet per minute with high-speed tools, and about twice that fast with carbides.  Tools should be kept sharp, ground, with an included angle of 80° to 100°, and with 10° to 16° side clearance.  Cutting can be done dry with proper exhaust or with the aid of a water soluble coolant.


Glass Based Grades


Conventional machining such as turning, boring, and facing can be done on automatic screw machines, CNC Lathes, production lathes or hand turret lathes.

Tungsten-Carbide or diamond tipped tools and cutters should be used with surface speeds below those used for paper or cloth base laminates.  Tools should be ground with a zero rake and machining can be done dry with an adequate exhaust system or with the aid of a water soluble coolant.



These suggestions reflect our experience and the experience of our customers.  This is not a users manual or fabrication guide.  Further, results differ based on many factors, including quality, composition and suitability of raw materials, tools and fabrication processes, and the skill of fabricators.  Atlas Fibre Company does not guarantee or warrantee fabrication results on any of our materials.
