SUMIBORON / Coated SUMIBORON Grade Guidance H Hardened Steel Machining Advantages of Using CBN In terms of cost investment, it is much lower in machine cost and overhead cost due to the fact that a CNC lathe is cheaper than a grinding machine. As for the quality of finish, inserts can machine different profiles and the finishing is also commendable as compared to grinding. Environmentally, sludge treatment for grinding is a hazard to the environment but for turning, the chips can be collected and recycled.

SUMIBORON Inserts Sumiboron Inserts and Edge Preparation Close-up of Cutting Edge All SUMIBORON inserts are enhanced with the optimum cutting edge preparation for various grades and geometries (shown on the rigth). This is to avoid cutting edge fracture caused by the heavy loads generated during the machining of high hardness materials such as Hardened Steel. As the pioneer of CBN tools „SUMIBORON“, various selection of grades and edge preparation combinations is our strong point for Hardened Steel machining.

CBN Insert Guidance Insert Types and Cutting Edge Geometries Characteristics Multi Cornered One-Use Type Inserts l One-use type inserts improve machining efficiency by using each cutting edge to its full potential following the numbering system on each cutting edge then throwing the insert away. l Multi cornered inserts have a single piece of Sumiboron mounted on every useable corner. Single sided inserts use the top corners whilst double sided inserts use both top and bottom corners. Diamond shaped inserts have 4 corners and triangular inserts have 6 corners. l A variety of Sumiboron...

SUMIBORON Break Master l SUMIBORON one-use insert with chipbreaker. l N-SV type is perfect for carburised layer removal while N-FV/N-LV types are best suited to finishing of hardened steel. l Breaker included on the CBN edge, chipbreaking effect can be maintained throughout machining process. l Unique breaker design can be applied to both hardened and non-hardened parts with effective chip control. Application Range N-SV For Carburised Layer Removal Ideal for carburised layer removal. Excellent chip evacuation under conditions with depth of cut at ≤ 0,3 mm. Application Examples SUMI BORON...
