  1. Precision brass rod W5000

  2. W5000 Round Rod W5000 the brass rod for highest demands Geometry The W5000 rod is our premium product for your high-precision machining. Due to the diameter tolerance h8 which is further reduced within a bundle, our size range 1.5 to 10 mm is particularly suitable for machining on automatic long-turning lathes running at high speeds. These sizes are available with a uniformly smooth surface drawn with diamond tools for the highest demands. – Inspected geometry for each rod. Our rods up to 80 mm usually have a much better straightness than 0,5 mm/m. – Cut lengths, no deviation within a batch – Reduced diameter variation within a batch – Minimal out-of-roundness – High uniformity of diameters within a rod/bundle/ packaging unit. Reduced tolerances for sizes 4 to 10 mm, within a bundle the diameter tolerance h8 is reduced to 5 µm and the out-of-roundness is restricted to 0.05 % of the diameter Our rods in sizes over 10 to 50 mm have been specially optimized for machining on multi-spindle automatic lathes. For diameters up to 30 mm we supply these rods with a tolerance h8. The end finish that is suitable for automated processing enables smooth feeding and unmanned operation.

Alternatively, they are available in bundles of up to 1,000 kg. The bundles are steel strapped several times over corrugated cardboard and in order to prevent them from sliding one bundle end is wrapped in jute sacking. These specifications apply to our standard packaging. Special packaging is available on request. Lead distribution The formation of needle chips is essentially determined by a balanced ratio between alpha and beta phases with homogeneous lead distribution. Lead results in short chips, low tool wear and cutting forces. Work efficiently and cost-effectively thanks to our consitant quality A calculation that pays off.
