http://beltechnologia.by/cat-4 The technology of cross-wedge rolling allows producing articles from billets that have round, hexahedral or square section and also from tube. As a result of cross-wedge rolling initial profile is transformed into round profile. 2026 BELTECHNOLOGIA.BY mill@open.by (Editor) ACE.CMS 1.4 1440 http://beltechnologia.by/_img/logo_rss.gif http://beltechnologia.by/cat-4 http://beltechnologia.by/post-143/lng-en/  New technology for manufacturing preforms of part «CONICAL PINION SHAFT» The part «conical pinion shaft» is widely used in the design of speed reducers. Technology Fri, 12 Jul 2019 00:00:00 +0300 http://beltechnologia.by/post-143/ http://beltechnologia.by/post-95/lng-en/ Mining tools are designed to equip work elements of coal, ore and salt mining machines. Its durability is always an actual problem. Product costs, productivity of mining and tunneling machines depend on tool durability. Urgency of a tool durability issue increases together with striving for cutting speed improvement. Technology Thu, 9 Feb 2012 00:00:00 +0300 http://beltechnologia.by/post-95/ http://beltechnologia.by/post-89/lng-en/ The method of cross-wedge rolling allows producing articles from billets that have round, hexahedral or square section and also from tube.
