Hole Finishing ROTAFLEX™ High-Performance Boring Systems General Application Hints • Identify your critical diameter (D). • Identify the maximum distance cutting edge (L) to critical diameter. Here are some examples: D D D L L Refer to this table for first investigation of application: Type of Tooling Stable Unstable Tests Necessary Twin Cutter Solid Tools <3,5 x D 3,5–6,5 x D >6,5 x D Twin Cutter Bridge Tools <3,5 x D 3,5–6,5 x D >6,5 x D Fine-Boring Heads with Boring Bar (FBHBB) <3,5 x D 3,5–5,0 x D >5,0 x D Fine-Boring Heads (FBH) <3,5 x D 3,5–5,0 x D >5,0 x D Fine-Boring Bridge Tools <3,5 x D 3,5–5,0 x D >5,0 x D Function of the tool isexpected without issueswithin recommendedcutting data.Application may requireMachining test mayreduced feeds and/or speedsbe required to identifycompared to stable conditions.cutting data.
