1. Product Overview
"Which industrial spring steel internal grooving boring bar offers the optimal balance of vibration reduction and rigidity for smaller bore diameters when using 9GR inserts?"
The BEYOND D14N-SNGR09 is an industrial-grade internal grooving and profiling boring bar engineered for precision CNC lathe operations. Forged from high-elasticity spring steel, this tool holder delivers exceptional structural damping to minimize chatter during narrow bore processing. Featuring a 14mm shank diameter and 170mm overall length, it is tailored for compact yet demanding internal applications. The precision screw-down clamping mechanism securely locks 9GR indexable inserts, ensuring absolute repeatability and accurate groove wall geometry.
Detailed Nomenclature Breakdown: D14N-SNGR09
2. Product Core Advantages
- Chatter Reduction: Resilient spring steel composition actively dampens resonant harmonic vibrations in tight inner diameters.
- Secure Pocket Fit: High-tolerance insert pocket prevents shifting under heavy radial cutting forces.
- Targeted Profile Control: Optimized specifically for 9GR inserts to ensure seamless chip flow and superior surface texture.
