What different cutting methods are there for stationary cutting?
The cutting of materials is an essential process in industrial manufacturing and metalworking environments.
Different cutting methods are used depending on the specific requirements that need to be met, such as the desired cutting quality or the economic efficiency. According to the material and the application, the cutting methods for stationary cutting differ depending on the positioning and relative motion of the cut-off wheel and workpiece.
Each of these methods has its own strengths and is suitable for certain applications.
What is a chop stroke cut and what sets it apart?
The chop stroke cut is a popular cutting method which is particularly used when cutting individual workpieces or small or slim material layers. The workpiece is cut by a cut-off wheel which moves in a radial movement around a joint mid-point.
What are the advantages of the chop stroke cut?
- Low vibrations: ensures neat cuts without vibrations.
- Efficient: shorter cutting times; ideal for fast work processes.
- Conserves material: less load on the cut-off wheel for smaller material dimensions.
What is an oscillation cut and what sets it apart?
The oscillation cut is a cutting method that is used in foundries, for example to remove risers and can also handle demanding wet cut-off grinding tasks. With this cutting process the cut-off wheel moves into the workpiece to be cut with additional forward and backward movements in the horizontal cut.
What are the advantages of the oscillation cut?
- Efficient use of energy: only requires a low drive output.
- Gentle machining: minimal heat input in the workpiece.
- Neat machining: optimum chip removal during the cutting process.
What is a horizontal cut and what are its features?
The horizontal cut is a cutting method that is suitable for cutting multiple adjacent workpieces or large materials such as slabs, plates and sheets. It is often used on the approach side of rolling mills, after the cooling bed.
What are the advantages of the horizontal cut?
- Efficiency: shorter cutting times enable rapid progress.
- High throughput capacity: cut-off wheel cuts the entire layer width of different cross sections in one cycle.
What is an index cut and what are its typical features?
The index cut is a cutting method used for very large, round solid materials and blocks frequently in steel works and foundries. The cutting process consists of several partial cuts: after each partial cut, the workpiece is rotated (2–4 partial cuts, 180–90° rotation, depending on the material dimensions).
What are the advantages of the index cut?
- Flexibility when working on large cross sections: enables very large material cross sections to be cut, even with smaller wheel diameters.
What is a rotary cut and what is special about this cutting method?
The rotary cut is a method for cutting very large pipes and round solid materials. The workpiece is continuously rotated during the cutting process, producing an even cut.
What are the advantages of the rotary cut?
- Flexible use of tools: small wheel diameters can be used.
- Efficient energy consumption: requires a lower drive output.
- Conserves material: keeps the workpiece temperature low.
