Honing tube processing principle

- Nov 29, 2019-

Honing is the use of one or more oilstones and honing tubes installed on the circumference of the honing head. The oilstone is expanded radially by an expansion mechanism (both rotary and push-type) to press it toward the hole wall of the workpiece. In order to create a certain surface contact. At the same time, the honing head is rotated and reciprocated without moving parts; or the honing head is only rotated and the workpiece is reciprocated to achieve honing.

In most cases, the honing head is floating between the machine tool spindle or the honing head and the workpiece holder. In this way, the honing head is guided by the hole wall of the workpiece during processing. Therefore, the machining accuracy is less affected by the accuracy of the machine tool, and the formation of the hole surface basically has the characteristics of the creation process. The so-called creation process is that the whetstone and the hole wall face each other and are trimmed to form the hole wall and the surface of the whetstone. Its principle is similar to the principle of two plane-moving plates facing each other to form a plane.
