Advances in Cutting, Sawing & Sawblades
100 S eptember 2009 ›
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
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.
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.
