Boring Head: Precision Tool for Enlarging Holes in Machining

A precision component mounted on boring or milling machine spindles for enlarging holes or improving hole accuracy. Equipped with fine adjustment mechanisms (e.g., precision dials), it controls hole machining tolerance within ±0.005mm, suitable for high-precision hole systems (e.g., engine blocks, hydraulic valve bodies).

Advantages of the product

Quick Tool Adjustment

Micrometer dials or digital readouts (resolution 0.001mm) enable rapid diameter adjustments, reducing setup times by 80% compared to traditional boring methods. Ideal for batch production of engine components.

With boring heads, contractors get flexibility for different sized holes because of their modular toolbox design that includes boring heads ranging from 10-32 mm and 25-80 mm, extension bars, and inserts. Boring heads also reduces iso 50 or bt40 tool holders stock holdings due to their interchangeable parts and the case with storage that holds setup calibration gauges which enables faster vernier caliper installation. These features are extremely advantageous for small job shops that work with miniature electronics as well as heavy machinery, allowing for quick changes from small to large diameter holes.

Frequently Asked Questions

What precision can boring heads achieve?

They achieve hole tolerances of ±0.005mm and surface finishes Ra≤1.6μm via fine-thread adjustment (0.5mm pitch) and carbide-tipped inserts for aerospace engine blocks and hydraulic valves.
They accommodate hole diameters from 5mm to 500mm, with adjustable cutting edges for both manual and CNC milling/boring machines (BT, HSK interfaces).
