GRINDING Techniques manufactures a range of cut-off discs in the Superflex brand to suit various application requirements.
When selecting a cut-off disc, certain important points have to be considered, including the material to be cut, the power rating of the machine, the speed at which the machine operates and the required accuracy and neatness of the cut.
When considering rail cutting applications, additional safety and material requirements are presented.
Conventional cut-off discs are designed to operate at a maximum peripheral speed of 80M/s. Due to the nature of rail cutting machines used, Superflex rail cut-off discs are designed to operate at a maximum peripheral speed of 100M/s to suit the more powerful petrol-driven machines.
Cut-Off Discs: Speed vs Safety
These machines have a remarkably high torque, which improves the performance, but also presents a safety issue upon cut completion. The discs may experience an overspeed due to the torque, which is accommodated for in the improved design.
Rail Cut-Off Discs: Zirconia Performance
When it comes to heavy-duty applications, the Superflex range includes two products that stand out.
The 350x4x25.4 A24Q and 400×4.2×25.4 A24Q rail cut-off discs. These discs are designed for use on large, portable petrol cut-off saws for cutting railways and other large steel sections.
When it comes to rail tracks, which are typically manufactured to be very hard to better handle the weight and stresses exerted upon them, updated grain technology has seen the introduction of the 350×4.2×25.4 ZA24S and 400×4.2×25.4 ZA24S Superflex Zirconia Alumina Rail cut-off discs.
Not only do these products reduce cutting time and overall cost per cut, but they also improve the effectiveness of each cutting operation. Capable of faster cuts, these discs also reduce the heat of the material on application for further improvement of overall performance.
