Multipass / Expansion Honing Tools

Vintages Multipass Honing Tools are engineered for high-precision internal finishing through a process of abrasive scrubbing and micro-grooving. These tools utilize radially expandable abrasive stones that ensure uniform material removal and accurate form control within bores.

During operation, the abrasive stones are both rotated and reciprocated inside the workpiece hole, while a controlled radial expansion pressure is applied. This mechanism ensures a high degree of surface finish and dimensional accuracy.

The grit size and grade of the abrasive stones play a crucial role in determining the level of surface roughness and form accuracy. This makes the tool ideal for applications demanding tight tolerances and superior bore quality.
