Viable alternatives to using rotary shears

LINSINGER Austria produces milling machines for pipe mills. For plate edge processing, the company uses the principle of circumferential milling. Pipe manufacturers continuously check their plants for productivity and operating costs. In the field of weld seam preparation, pipe mills cannot avoid milling technology. Previously used processes such as trimming the edges with rotary shears demonstrate serious disadvantages. Flaws and structural deformation of welding edges produce seam defects, and high material costs are caused by process- related oversizes. A well-known Asian pipe mill, which already has over 15 Linsinger machines in use, focuses on the approved strip edge milling of Linsinger. After one year of production, management observed that productivity had increased and operating costs had decreased, while pipe errors were reduced to almost nil. AdvantagesofLinsingerstripedgemilling machines include a flawless and clean metal surface, no structural deformation through cutting processing because the surface does not warmup, and interference-

free chip flow on account of short chips, which are disposed of by chain conveyor belts. Height copying milling units ensure precise welding edges, including corrugated plates, and perfect exploitation of carbide plates. Accurate welding slit is caused by

higher precision of produced welding edges, and a 45m/min welding speed is possible. Linsinger Maschinenbau GmbH – Austria Fax: +43 7613 8840 38 Email: maschinenbau@linsinger.com Website: www.linsinger.com
