SBN Cutting Tool System

August 01, 2015

Indexable finishing inserts have arrived with the new EDGE² Spherical ball nose (SBN) system from DAPRA Corp.

SBN inserts feature two usable cutting edges, delivering both cost savings and the high-quality finishes. Thick carbide construction enhances heat and stress absorption, and outstanding insert life allows for the long unattended finishing runs, with fine surface finishes created by an improved grinding process, according to the company. The SBN series is also excellent for tip-cutting, 3D profiling, semifinishing and light roughing.

Fully through-hardened SBN cutter bodies provide optimal strength and longevity. High accuracy and centrality ensure minimal runout to enhance surface finishes and tool life, and a close-tolerance insert pocket produced by EDMing removes less body material for improved insert support. Solid-carbide and carbide-core cutter bodies are available, as well as screw-on modular heads and modular extensions.

  • grinding


    Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.

  • profiling


    Machining vertical edges of workpieces having irregular contours; normally performed with an endmill in a vertical spindle on a milling machine or with a profiler, following a pattern. See mill, milling machine.
