The Yellow River Cyclone successfully developed and processed innovative PCBN CNC blades for quenching steel
Recently, the Yellow River Cyclone Diamond and Cubic Boron Nitride Cutting Tool Project Group successfully developed an innovative polycrystalline cubic boron nitride PCBN CNC blade for alloyed substrate for quenched steel. The main feature of this product is to use the company's self-developed polycrystalline CBN sheet instead of imported hardened steel composite sheet, with high-precision imported automatic sharpening equipment and high-precision testing equipment to provide customers with quality products. In recent years, polycrystalline cubic boron nitride PCBN tools have been widely used in the field of ferrous metal cutting, mainly used in machine tools, bearings, gears, gear shafts, molds and other industries with high hardness and difficult to process materials. Cutting processing. The company's diamond and cubic boron nitride cutting tool project team has been committed to the production and development of PCBN superhard tools. The main products are welded CBN tools, integral polycrystalline CBN tools, transparent welded CBN tools and some non-standard tools. I. Application Fields Innovative PCBN CNC inserts for processing hardened steel are mainly used for high-hardness steel parts after heat treatment, such as gears, gear shafts, bearings, etc., hardness HRC45~HRC68. Second, the product advantage 1. Self-developed PCBN material, for the continuous, light and medium intermittent of the hardened steel has been specially optimized, wear resistance has reached 80% of the similar products of internationally renowned companies, impact resistance is 1.3 times . 2. The product has good impact resistance. The layered CBN poly wafer replaces the traditional PCBN composite sheet and is sintered by vacuum brazing process, which avoids the delamination risk of the traditional PCBN composite sheet, and the PCBN thickness can reach (1.2-1.5) mm, which significantly improves the product's impact resistance. . 3. The cost advantage is obvious and the cost performance is high. Using self-developed PCBN poly wafers to cut into triangular triangular knives, maximizing the use of PCBN materials, the cost of accounting materials is only one-tenth of the original cost, significantly reducing product cost while achieving comparable performance with similar foreign products. . Third, the processing case 1. Moderate intermittent finishing Workpiece name: Gear Workpiece material: 40Cr HRC58~62 Processing position: outer circle, end face (with 8 holes) Use blade: CNGA120408 Comparison effect:
