Solid Carbide Lathe Boring Tool Micro Turning Bar Tiny Precision Components

Introduction:

A solid carbide lathe boring tool (micro turning bar) is a high-precision cutting tool designed for small-diameter internal turning, boring, and fine-finishing operations on CNC lathes or Swiss-type machines. These tools are ideal for achieving tight tolerances and superior surface finishes in micro-machining applications.

Features:

1. Key Specifications for Micro Components

• Diameter Range: Ø0.1mm – Ø3mm (sub-millimeter tools available)

• Reach: 4×D to 10×D (e.g., a 0.5mm bar can bore 5mm deep)

• Tolerances: ±0.002mm (for medical/dental implants)

• Coatings: Diamond-like (DLC) or TiAlN for non-ferrous/steels

• Coolant: With or Without Through-tool coolant (critical for chip evacuation)

2. Best Tool Geometries for Tiny Parts

• Sharp, polished edges – Burr-free finishes (Ra < 0.2 µm)

• Negative rake angles – For stability in hardened steels

• Reduced neck design – Maximizes rigidity in deep holes

Critical Setup Tips

1. Tool Holding:

   • Hydraulic chucks (e.g., SCHUNK Tendo Nano) for <1µm runout.

   • Avoid collets if runout >0.005mm.

1. Workpiece Stability:

   • Use micro chucks or vacuum fixtures for <1mm parts.

2. Vibration Control:

   • Dampened tool holders (e.g., Big Kaiser Micro).

Specialty Applications

Medical (Bone Screws, Dental Implants)

Watchmaking (Gear Pivots, <0.2mm Holes)

Aerospace (Fuel Nozzles, Inconel Micro-Holes)
