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:
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)
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
Tool Holding:
Hydraulic chucks (e.g., SCHUNK Tendo Nano) for <1µm runout.
Avoid collets if runout >0.005mm.
Workpiece Stability:
Use micro chucks or vacuum fixtures for <1mm parts.
Vibration Control:
Dampened tool holders (e.g., Big Kaiser Micro).
