hiStoryThe company was founded in 1939. Early in 1959 the company merged into the VOEST Group and started to manufacture the first road rolling equipment. At the end of the seventies the company entered into the defence industry. In 1993 the company was taken over by the managing group of Bank Austria. A new company named Maschinenfabrik Liezen und Gießerei GmbH was formed on November 15, 1994.

During the next few years MFL has taken over several companies and created different manufactu-ring divisions within MFL. In 1998 a new department of sawing and milling technology was success-fully integrated into MFL. The new department specializes in “turnkey” solutions for its customers.

MFL is well known for their com-bined use of the latest state of the art technologies and experience to develop and design the best equipment available.

railmilling machine

The railmilling machine is used for the removal of

- Short pitch corrugation - Near surface defects- Defects of the rail head shape

in main-line and underground tracks.

mobile railmilling machine

advantages for the user:

- No dismounting of tracks

- Processing of the rail head in one pass

Special machinery

ring Splitting machine

The ring splitting machine type rTA 120/1000-22 is used primarily in ring rolling mills to separate multi-ple rings. The maximum initial height of the multiple ring is 600 mm.

It is cut into segments of 38 to 300 mm. The current ring diameter is 500 mm to 1200 mm. Of course the machine can also be designed to process larger multiple rings.

This patented machine can increase production and quality considerably.

advantages for the user:

- Optimal work load of the rolling mill by subsequent separation of the rings by the ring splitting machine

- Cost-saving production of rings with a low initial height

- High plane parallelism and nearly burr free surface of the produced rings

- Short cycle times and resulting of this an increased output

- Dry working process

- Short chips

Cutting process Manipulation Separated ring segments

toolS

Saw bladeS

The saw blade with exchangeable carbides is a new and already patented development of MFL.

advantages for the user:

- Less investment costs compared to brazed saw blades because a lower number of saw blades is required for the running operation

- No grinding centre and transport to grinding shops is necessary

- Increased life time / productivity by an individual coating of the carbides

- Optimum adjustment to special materials is possible

milling toolS

The milling tools consist of a base body which is equipped with exchangeable cassettes. These cassettes include the cutting tips. The milling tools are used for the welding seam preparation and for the preparation of different profile shapes.

advantages for the user:

- Preparation of different profile shapes with one base body only because the base body can be equipped with different cassettes

- Exchangeable cassettes protect the base body from damage (in case of a crash only the cassettes have to be exchanged) - Cost saving!
