‌Material Compatibility Analysis for Portable Lathes

Portable lathes are designed for machining cylindrical components across diverse materials. Understanding material properties ensures optimal operational parameters and tooling configurations.

‌Common Processed Materials:‌

1. ‌Carbon Steel (C ≤ 0.6%)‌

• Machinability Rating: HB 150-220

• Tooling: Coated carbide inserts with 5°–10° positive rake angles

• Speed Range: 80–200 RPM

2. ‌Stainless Steel (AISI 304/316)‌

• Work Hardening Sensitivity: Requires continuous feed > 0.1 mm/rev

• Coolant: Emulsified oil for heat dissipation

3. ‌Aluminum Alloys (6061/7075)‌

• Chip Control: High-speed steel (HSS) tools with polished edges

• Speed Range: 600–1,200 RPM

4. ‌Copper/Bronze Alloys‌

• Deformation Risk: Reduced feed rates (0.05–0.15 mm/rev)

5. ‌Thermoplastics (ABS, Nylon)‌

• Tool Geometry: Ground carbide tools with 0° clearance angles

‌Operational Guidelines:‌

• Hardness Limits: Portable lathes typically process materials ≤ HRC 40

• Thermal Expansion: Critical for large-diameter polymer machining

• Vibration Mitigation: Damping tool holders recommended for brittle alloys

‌Applications:‌
Repairing shafts, flanges, and bushings in aerospace, marine, and petrochemical industries.
