Vibration reduction in lathe machining requires comprehensive optimization from process, tooling, and equipment aspects:

‌I. Process Parameter Optimization‌

• ‌Reduce cutting speed and feed rate‌: Minimize cutting force fluctuations to avoid self-excited vibration.

• ‌Increase cutting depth‌: Enhance workpiece rigidity to suppress low-frequency vibration (50-300Hz).

• ‌Control overhang length‌: For slender parts, use steady rests or center supports.

‌II. Tooling System Improvement‌

• ‌Increase tool lead angle‌: Reduce radial cutting force (Fy); 90° lead angle is recommended.

• ‌Blunt tool edge‌: Wear on flank face of 0.2-0.3mm can suppress "chipping" phenomenon.

• ‌Use vibration-damping tool holders‌: e.g., Capto® modular tool holder; use Silent Tools™ when overhang >4 times diameter.

‌III. Equipment Enhancement Measures‌

• ‌Install vibration isolation devices‌: Air spring isolators can absorb ground micro-vibration and improve surface finish.

• ‌Increase system rigidity‌: Prioritize high-rigidity tool holders and avoid negative stiffness structures.

• ‌Dynamic balance adjustment‌: required when spindle speed >20,000 rpm.
