Boring & Milling Machines

Boring and milling machines are used for precision hole finishing, bore diameter correction, face milling, and machining of reference surfaces. They are commonly applied to housings, flanges, valve bodies, gearbox components, and other parts where bore alignment, dimensional consistency, and surface quality are important.

A suitable boring and milling system must consider bore diameter, cutting depth, tool interface, spindle speed, required power, workpiece material, feed travel, and structural rigidity. The relationship between the spindle, slide unit, fixture, and workpiece must also be carefully planned to maintain stable tool alignment throughout the machining process.

HANN KUEN offers a broad range of boring and milling spindle heads, including conventional spindle heads, built-in motor spindles, direct magnetic motor spindles, and automatic tool-change spindle heads. Different spindle interfaces and power ranges are available to support various machining conditions.

When combined with servo linear guideway slides or hardened guideway slides, these spindle heads can form compact boring and milling units for horizontal, vertical, or customized machine layouts. The configuration can be selected according to the required accuracy, cutting load, feed stroke, and automation method.
