Boring Bars_All type series_Catalog

This comprehensive catalog showcases an extensive array of boring bars designed for precision internal machining, systematically categorized into various product series such as Dimple Bar, Micro-Mini Twin, Micro-Mini, Micro-Dex, F-Type, S-Type, P-Type, M-Type, D-Type Boring Heads, and AL-Type specifically for non-ferrous metals. A paramount technical advantage across these series is their superior vibration resistance, meticulously engineered through innovative lightweight dimple heads and robust anti-vibration carbide shanks. This design is critical for achieving and maintaining exceptional precision and surface quality, even in the most demanding internal machining operations. Furthermore, enhanced chip evacuation is a key functional feature, effectively facilitated by dual chip channels and integrated internal coolant supply in many advanced models. This design actively prevents chip interference, significantly improving both machining efficiency and tool longevity. The catalog provides exhaustive technical specifications, including a wide range of KAPR (cutting edge lead angles spanning from 75° to 142°), precisely optimized I/d ratios (representing the projection length to shank diameter, typically ranging from 3 to 8 times depending on the shank material and series), and a broad spectrum of minimum cutting diameters. This versatility enables their application across a vast array of internal machining tasks, from intricate small-diameter holes to larger bore operations. These boring bars are engineered to accommodate diverse insert types, including CCOO, CPOO, DCOO, TPOO, WBOO, and VCOO geometries, along with specialized chip breakers (e.g., finish, light, medium, CBN/PCD) meticulously tailored for specific workpiece materials such as carbon steel, alloy steel, stainless steel, gray cast iron, non-ferrous metals, and hardened steel. Each detailed product entry within the catalog furnishes essential data, including unique order numbers, compatible inserts, comprehensive dimensions, and expertly recommended cutting conditions, making the catalog an indispensable and authoritative guide for engineers and machinists seeking to select the optimal tool for achieving efficient, precise, and high-quality internal machining results.
