Cutting High Strength Steel
Cutting high strength steel can be challenging but it is possible with the right tools, techniques and precautions. The increased strength of steel materials has caused manufacturing processes to change, which in turn requires a larger inventory of tools and methods to get the job done quickly and safely. Cutting high strength steel requires precision, patience and knowledge to obtain the correct results. This article will discuss the tools, techniques and safety precautions associated with cutting high strength steel.
Tooling Up
When cutting high strength steel, it is essential to use the correct type of tooling. Smaller tools, such as standard twist drills, will not be able to handle the extreme strength of this type of metal. Instead, carbide drills, end mills and reamers are highly recommended for cutting high strength steel. In addition, a drill press or milling machine is needed for accurate, flawless cuts.
Using the Right Lubricants
In order to ensure consistent, closely toleranced cuts, the use of lubricants is often necessary. Lubricants reduce heat generated by the friction between the cutting tool and the material being cut. This will reduce build-up of swarf and reduce turbulence that may cause the workpiece to vibrate with faster cutting speeds. The type of lubricant used depends on the application and the type of metal being cut and should be selected carefully.
Safety First
When cutting high strength steel, extreme caution must be taken to protect workers. The high-speed tools and machinery used in this process can cause serious injury and property damage if not used correctly. Safety glasses and other protective gear must be worn at all times and areas around the cutting area must be kept free of obstructions. Clear communication between workers is also essential to keep everyone informed of the necessary safety precautions.
Conclusion
Cutting high strength steel can be a challenging and potentially dangerous task. When approached with the correct tools, techniques and safety precautions, however, it is possible to obtain the high-quality, closely toleranced parts required to complete the job. Adopting the procedures outlined in this article will ensure that the cutting process is completed safely and successfully.
