Replaces traditional grinding processes with high-speed “Hard Turning” ( HT ) on automotive transmission shafts, gears, bearings, and mold dies, maintaining sub-micron tracking tolerances.<\/li>\n\n\n\n
Resists severe abrasive wear when face milling or turning heavy industrial pumps, mill rolls, and automotive brake rotors, allowing high-velocity material removal rates ( MRR ).<\/li>\n\n\n\n
Overcomes the micro-interrupted impact stresses inherent in porous automotive valve seats, guides, and gears without micro-chipping along the cutting edge.<\/li>\n\n\n\n
Maintains high chemical inertness and red-hardness under searing friction zone temperatures (\u2265 1000\u00b0C), preventing rapid crater wear.<\/li>\n<\/ul>\n\n\n\n
PCD Models & Specs<\/strong><\/strong><\/p>\n\n\n\n 1. Diffusion Bonding Immunity Against Thermal Delamination<\/strong><\/strong><\/p>\n\n\n\n Standard tipped CBN tools rely on a razor-thin layer of vacuum braze silver\/copper paste. When cutting hardened steel at high speeds, temperatures in the shear zone frequently spike past 800\u00b0C, degrading the braze strength and causing the CBN tip to instantly fly off (delaminate).<\/p>\n\n\n\n Uking\u2019s Hybrid Welding technology utilizes an ultra-high-pressure high-temperature co-diffusion process. The transition alloy layer morphs into the carbide backing and the CBN matrix simultaneously, creating a seamless gradient structural profile. With zero conventional braze seams to degrade, the insert operates smoothly at elevated cutting velocities ( Vc\u2265<\/strong>200\u00a0m\/min) with absolute process safety.<\/p>\n\n\n\n 2. Micro-Honed Chamfer Geometry & Tailored CBN Content<\/strong><\/strong><\/p>\n\n\n\n To combat edge micro-chipping, every Hybrid Welding batch receives customized, automated edge preparation:<\/p>\n\n\n\n High-Content CBN (~85%\u201395%):<\/strong> Sintered with a metallic binder (Co-Al) network, optimizing thermal conductivity and fracture toughness for heavily interrupted cast iron milling.<\/p>\n\n\n\n Low\/Medium-Content CBN (~50%\u201365%):<\/strong> Bound within a ceramic matrix (TiN\/TiC), maximizing chemical wear resistance and crater hardness for high-speed continuous hard turning ( \u2265180 m\/min\u00a0<\/strong>).<\/p>\n\n\n\n Each insert edge is polished with specific S-lands (honed round edges) or T-lands (negative chamfers) to protect the tip from sudden mechanical fracture during the initial cut entry.<\/p>\n\n\n\n Why Choose Uking Diamond Brazed CBN Inserts?<\/strong><\/p>\n\n\n\n Delamination-Free Process Stability: <\/strong>Diffusion-welded interfaces guarantee zero tip structural detachment, even during high-temperature dry cut cycles.<\/p>\n\n\n\n Cost-Per-Edge Optimization:<\/strong> Features solid hybrid integration that allows multi-tip configuration per blank, multiplying your cutting corners and reducing tooling costs.<\/p>\n\n\n\n Elimination of Grinding Processes:<\/strong> Replaces expensive, slow grinding with high-efficiency hard-turning, reducing total cycle times by up to 60%.Strict Micron-Level Runout Control: Each insert is laser-inspected to fit flawlessly into international standard tool holders with zero centerline indexing deviation.<\/p>\n\n\n\n Model: VNGA1604-H Model: VCGW1604-H VBGW1604-H Model: DNGA1504-H Model: DNGA1506-H Stop watching your profit margins grind away on low-tier brazed inserts that disintegrate under high thermal shear stress. Backed by 20 years of ultra-high pressure and advanced plasma synthesis authoritative metallurgical engineering in Henan, China, Uking Diamond manufactures industrial-grade Hybrid Welding CBN inserts that maximize your machine tool uptime and push your component reject rates to absolute zero.<\/p>\n\n\n\n Because advanced hybrid-diffusion CBN inserts are high-capital, high-efficiency production assets, we do not distribute unchecked free samples.
