  • Phenolic Machining – Norva Plastics

    In many cases, the same machining operations employed in the fabrication of metals and wood may also be adapted to glass base grades. However, certain slight changes in tools and the use of proper speeds are necessary. Diamond or tungsten-carbide tools will give more satisfactory work with longer, more economical life than high-speed steel tools.

  • Machining UHMW: Why Is Holding Tolerances So Difficult ...

    2017-10-10 · Yet machining is a must, since the material is impossible to mold. Like all polyethylenes, UHMW has a low melting point (270°) and a high COF (120 x10" IN/IN/ÜF), which all contribute to the challenge. Limit heat! For best results, it''s critical to reduce heat buildup, since the very act of machining generates friction, and thus, heat.
