In the modern manufacturing industry, PCBN tools are increasingly widely used, and the improvement of their service life and machining efficiency has become the focus of attention of many enterprises.Among them, the correct choice of edge treatment style plays a crucial role in this process.This is not a simple decision, but requires a comprehensive consideration of a number of factors, including the characteristics of the processing material, cutting parameter settings, the actual processing conditions and tool materials.Zhengzhou Bote with years of accumulated experience, summed up a set of important reference value of PCBN tool edge processing style selection guide.

First, according to the characteristics of the processing material custom edge design

The hardness and toughness of the machining material is one of the key factors in deciding the style of edge treatment.For materials with high hardness, such as hardened steel, the use of negative chamfer angle and wider width of the edge design can effectively enhance the structural strength of the tool.In the case of Zhengzhou Bote's BTS6000 inserts, for example, when machining hardened steel, the 30o negative chamfer angle and 0.2mm width of the cutting edge of the S02030 model greatly reduces the risk of chipping and ensures the stability of the machining process.On the other hand, for tougher materials, such as cast iron sintered alloys, smaller negative chamfer angles and narrower widths are more appropriate.The 15o negative chamfer angle and 0.1mm width of the T01015 version of the Burt's BTS2800 insert help to improve cutting efficiency and at the same time enhance the surface quality of the finished product to meet the demands of high-precision machining.

Second, cutting parameters and edge treatment of synergistic optimisation

The setting of cutting parameters directly affects the choice of edge treatment style.In the high-speed cutting scenario, in order to reduce cutting resistance and friction heat, and improve machining efficiency, the edge with small negative chamfer angle and narrow width should be selected, and moderate passivation treatment should be carried out.This kind of edge treatment can not only reduce the friction between the tool and the workpiece, but also effectively reduce the impact and vibration in the cutting process, and extend the service life of the tool.In the low-speed heavy cutting, due to the cutting force is larger, the tool needs to have a stronger ability to withstand.Therefore, the choice of negative chamfer angle, wide width of the edge, and appropriately increase the passivation treatment, can enhance the ability of the tool to withstand large cutting forces and impact, to ensure the smooth progress of the machining process!

Third, the processing conditions and cutting environment dominated edge style

Machining conditions and cutting environment are also factors that should not be ignored.In continuous cutting operations, especially for those who require high precision and surface quality of the machining task, negative chamfer angle is small and after appropriate passivation of the edge is the ideal choice.This significantly reduces vibration and heat build-up, which improves machining accuracy and ensures consistent product quality.In interrupted cutting environments, tools are exposed to frequent impacts and load changes, requiring high durability and impact resistance.Therefore, the negative chamfer angle should be selected and strengthened edge treatment to enhance the tool's ability to resist damage, extend its service life, reduce processing costs.

Fourth, the suitability of tool material and edge treatment

Different PCBN materials have unique mechanical properties and cutting performance, which requires the choice of edge treatment style must be matched.Only to ensure that the edge treatment and tool material complement each other, in order to give full play to the advantages of PCBN tools, to achieve maximum machining efficiency and service life.

In summary, the optimization of PCBN tool cutting edge processing style selection is a complex and systematic project, which requires a careful analysis of the machining material, cutting parameters, machining environment and tool characteristics and other multi-dimensional factors.Through accurate matching and combination, enterprises can greatly improve the service life of PCBN tools and machining efficiency, injecting strong power for the development of modern manufacturing industry, and occupying a favourable position in the fierce market competition.
