MFL Maschinenfabrik Liezen Rail Milling Machines, Rail Sawing and Drilling Equipment, Rail Production Lines
Austria-based Maschinenfabrik Liezen und Gießerei (MFL) is a world-leading supplier of stationary and mobile rail milling and rail processing machines. MFL also delivers complete rail production lines as general contractor. MFL is engaged with rail processing technologies for more than ten years and offers a wide range of experience and know-how. Continuous development and advancement guarantee our customers machines that are always state of the art.
Mobile rail milling machines
MFL’s rail milling machines are an effective and efficient servicing method. The machines are able to operate on all kinds of track, including main line and metro systems. By an enormous material removal rate of up to 8mm, the milling process guarantees a perfect cross-profile after one pass only. This high productivity can be reached without production of sparks and dust and without leaving dirt. Milling technology does not only protect the environment, it also prevents pollution of the track bed. 99.9% of the produced chips are removed by a suction device and can be resold as high-grade steel scrap.
Due to the reduction of tool and auxiliary costs (purification of the track, tunnel, etc.) compared to grinding, the milling process contributes essentially to the economic success of an organisation.
Stationary rail milling machines
The mobile rail milling technology can also be used stationary. All technical advantages are included in the stationary rail milling machines as well.
High working speeds:
- Removal rates up to 8mm in one working process
- Surface roughness after milling Ra < 4 µm
The stationary rail milling process is continuously. Equipped with handling system (loading and finishing units), as well as tool changing systems of MFL, shift operation can be realised easily. Combined with the mentioned technical benefits, the economic operation of the machine cannot be topped.
Rail sawing and drilling machines
The rail sawing and drilling machine cuts and drills rails in one working process. MFL offers customised and turnkey solutions. The rail sawing and drilling machine is characterised by the following features:
- Horizontal and vertical adjustable drilling spindles
- Temperature compensation to ensure an exact cutting length under different temperature conditions
- Guaranteed length tolerance for rails from 5m – 120m
- Processable rail profile (HxW): 200mm x 220mm
- Number of drillers: 1 – 6 Stück
- Drilling diameter: 20mm – 40mm
- Saw blade diameter: 660mm
Rail drilling and milling machines
The rail drilling and milling machine is used for the production of round and slotted holes at the rail web. A precise chamfering within very tight tolerances is possible. Beside the most important feature of processing round and slotted holes with one machine only, the rail drilling and milling machine offers the following advantages:
- Vertical and horizontal processing of slotted holes
- Web measuring device for recognition of markings
- Exact length positioning by material feeding tongs
- Manipulator for automatic tool change
- Number of drilling stations: 1
- Number of chamfering stations: 1
- Chamfering angle: 30° / 45°
- Chamfering tolerance: +/- 0.1 mm
Special machinery / axle sawing machines
The core competence of MFL is the machine tool manufacturing. This is reflected by MFL special machinery used all over the world and esteemed by professionals.
In addition to customised solutions for standard applications, MFL engineers are known for innovative ideas for special machinery. As an example the axle sawing machine is mentioned below.
The axle sawing machine is a horizontal single cut sawing machine for exact cutting of axles. The machine does the fully automatic cutting, centering and face milling of axles.
MFL sawing machines are equipped with carbide-tipped saw blades that ensure high performance and a long service life with fewer associated costs. MFL also supplies complete rail production lines as a general contractor.
