Screw and fine boring heads include high precision features for enlarging holes and have single-point insert cutting tools and fine pitch (0.5 mm) feeding mechanisms for incremental diameter changes (resolution: 0.001mm). Using heat treated steel with a hardness of 58-62 HRC, they achieve hole tolerances of ±0.005mm with surface finishes Ra≤1.6μm. They are extensively applicable in manual and CNC machining of automotive engine blocks and hydraulic valve bodies.

Frequently Asked Questions

How do boring heads handle heavy cuts?

Forged steel bodies (hardness 58-62HRC) and anti-backlash mechanisms resist deflection during heavy cuts (axial load up to 50kN), suitable for deep-hole boring (depth-to-diameter >15:1).
Yes, they comply with ISO 5089 and ASME B5.48, ensuring accuracy in automotive, aerospace, and heavy machinery industries for global manufacturing compatibility.
