Deep hole processing is an important technology in the machinery manufacturing industry, especially in aerospace, automobile manufacturing and other fields. However, cutting blockage is a common and thorny problem in the deep hole processing process. Cutting blockage not only affects the processing efficiency, but also may cause tool damage and workpiece scrapping. As a tool specially used for deep hole processing, the design and use strategy of the keyhole knife play a key role in avoiding cutting blockage.
The design of the keyhole knife fully considers the special needs of deep hole processing. Its cutting edge is usually narrow, which helps to reduce cutting resistance and make the cutting process smoother. At the same time, the chip groove design of the keyhole knife is also particularly important. Reasonable chip grooves can ensure that the chips are discharged smoothly and avoid accumulation in the hole. The shape, size and position of the chip groove need to be carefully calculated to ensure that the chips can be discharged smoothly along the predetermined path during the cutting process.
When using the keyhole knife for deep hole processing, the reasonable selection of cutting parameters is also the key to avoiding cutting blockage. Parameters such as cutting speed, feed rate and cutting depth will directly affect the generation and discharge of chips. Too high cutting speed or too large feed rate may lead to excessive cutting chips and increase the risk of blockage. Therefore, in actual processing, it is necessary to reasonably select cutting parameters according to factors such as workpiece material, tool type and processing requirements to ensure the stability and efficiency of the cutting process.
In addition, the correct use of cutting fluid is also an important measure to avoid cutting blockage. Cutting fluid can not only cool the tool and workpiece and reduce the cutting temperature, but also play a role in lubrication and cleaning. In deep hole processing, the cutting fluid is injected into the hole through the nozzle, and after mixing with the cutting chips, it forms a muddy substance, which helps the smooth discharge of the cutting chips. Therefore, choosing a suitable cutting fluid and reasonably setting parameters such as the injection pressure and flow rate of the cutting fluid are of great significance to avoid cutting blockage.
The design of keyhole knife, the reasonable selection of cutting parameters and the correct use of cutting fluid are the key to avoiding cutting blockage in deep hole processing. In actual processing, these factors need to be comprehensively considered according to the specific situation to ensure the smooth progress of the processing process and the stable improvement of workpiece quality.
