The structure of the oscillating reamer holder consists of a fixed part and a mobile part, allowing the tool to adapt perfectly to the hole and to the spindle’s rotation axis, automatically correcting possible radial and horizontal alignment errors. This feature makes it an essential accessory for operations on parallel lathes, automatic lathes, conventional machine tools, and CNC machining centers, suitable for ferrous and non-ferrous materials as well as light alloys.

 

The operating principle is based on a combination of rigidity and controlled mobility. The fixed part, through the cylindrical shank, anchors firmly to the machine tool, while the mobile part allows the reamer to automatically compensate for misalignment.

 

Radial error adjustment is carried out by acting on the adjustment screw that regulates the force of the internal spring, ensuring correct centering even in horizontal positions. To correct horizontal oscillation error, the nut can be slightly loosened, creating a small clearance that enables a controlled pendular movement. In this way, the reamer naturally aligns with the axis of the rotating workpiece, ensuring a high-quality and precise hole finish.

 

Thanks to these features, the oscillating reamer holder with cylindrical shank provides a significant improvement in hole quality, extended tool life, and enhanced process reliability. The reduction of waste and machining time makes it the ideal choice for precision mechanical and industrial applications that require consistent and repeatable results over time.
