High-hardness materials are increasingly common in engineering and manufacturing fields, such as stainless steel, titanium alloys, etc. Due to its higher hardness, the processing difficulty also increases accordingly. This article will introduce several methods to help you understand how tubesheet drills deal with high-hardness materials and improve processing efficiency.

First, choose the right tool material and coating. Drilling high-hardness materials requires tools with better wear resistance and rigidity. The use of carbide (such as tungsten-titanium alloy) or coated tools (such as diamond coating) can effectively improve the hardness and wear resistance of the tool. These tools maintain a long service life on hard materials and reduce cutting forces and friction.

Second, adjust the cutting parameters. Since it is difficult to cut high-hardness materials, the cutting speed, feed rate and cutting depth need to be adjusted according to the hardness and characteristics of the specific material. Generally speaking, for high-hardness materials, the cutting depth can be reduced and the cutting speed and feed speed can be increased to improve cutting efficiency and reduce cutting force.

Third, use lubricants and coolants. During drilling of hard materials, friction and heat increase the risk of tool wear and workpiece deformation. By using appropriate lubricants and coolants, friction can be effectively reduced and the tool and workpiece cooled, the temperature reduced, tool wear and plastic deformation of the material reduced, and the processing quality improved.

In addition, the use of appropriate processing strategies can also improve the processing effect of tubesheet drills on high-hardness materials. During the machining process, you can use the method of pre-drilling small holes before drilling to reduce the pressure at the bottom of the hole and make it easier for the tool to cut in. At the same time, the use of accessories such as tool chip extractors, chip sleeves and cooling gas injection devices can help better handle the chips and heat generated during the processing of high-hardness materials.

Finally, regular inspection and maintenance of cutting tools is key to ensuring drilling of high-hardness materials. Replace severely worn or damaged tools in a timely manner to ensure cutting results and processing quality. At the same time, keeping the cutting tool sharp and in good condition can reduce cutting force and extend the service life of the cutting tool.
