Hole Finishing ROTAFLEX High-Performance Boring Systems Widia General Application Hints Identify your critical diameter (D). Identify the maximum distance cutting edge (L) to critical diameter. Here are some examples 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 is expected without issues within recommended cutting data. Application may require reduced feeds and/or speeds compared to stable conditions. Machining test may be required to identify cutting data. Causes of and remedies for rough and fine boring problems It is generally assumed that the tools have been properly mounted as per the technical recommendations in this catalogue. Problem Cause Possible Remedy Vibration tendency 1. Overhang 2. Choice of insert 3. Cutting data Adjust L/D ratio Select 90° lead angle on rough boring tools Select inserts with positive geometry Select inserts with smaller corner radius Reduce depth of cut I ncrease feed D L Slight chatter marks on surface 1. Choice of insert 2. Cutting data 3.
