Carbon tipped saw blade technology

Another recent invention from MFL is a ring splitting machine used primarily in ring mills to separate multiple rings. The machine is equipped with a carbide tipped saw blade and cuts the ring in an interpolated process from the inside out. MFL is an experienced manufacturer of sawing and milling equipment, and says it constantly refines and develops its machines to increase service life. The company’s product range includes single and layer sawing machines for tubes, billets, rails and profiles. Each of these machines is designed to use carbide tipped saw blades, which it claims ensure high performance, low costs and long service life. The company’s plate and strip edge milling machines are mainly used for the edge preparation of longitudinal welded pipes in the shipbuilding and spiral pipe industry. Maschinenfabrik Liezen und Gießerei GmbH – Austria

MASCHINENFABRIK Liezen und Gießerei GmbH (MFL), Austria, has introduced saw blade technology, which it says is aimed at customers requiring a longer service life and lower investment cost. The saw blade features exchangeable carbide tips. While common saw blades have the carbides brazed at the tooth, the carbides of the MFL saw blades are clamped  MFL’s sawblades feature exchangeable carbide tips

into the gap between the main body and the tooth. The clamped carbide tips are easily exchanged, removing the need for expensive grinding centres. The removal of long transport times for regrinding of saw blades also means that less basic equipment is required. Successful trials at the MFL workshop in Liezen have already been finalised, and a durability test is due to be started soon.
