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
Viable alternatives to using rotary shears
 Linsinger’s BFMK 90/800D double strip edge milling machine
higher precision of produced welding edges,
and a 45m/min welding speed is possible.
