The Machining Principle Of Honed Cylinder Tube

2025-09-11

The machining principle of honed cylinder tubes is based on micro-cutting achieved through a combined rotational and reciprocating motion of the honing tool. This process utilizes abrasive stones mounted on a honing head to interact with the inner surface of the workpiece, forming a cross-hatched pattern that improves geometric accuracy and reduces surface roughness. The following sections detail the core principles and mechanisms involved: I. Basic Motion Mechanism The honing head drives abrasive stones (honing sticks) to perform two simultaneous motions: Rotational Motion: The honing head rotates around its axis, generating circumferential cutting traces. Reciprocating Motion: The honing head moves axially back and forth, producing linear cutting traces. Combined Effect: The superposition of these motions creates a cross-hatched pattern with a typical angle of 30°–60° (adjustable based on requirements). This pattern enhances oil retention, reduces friction, and improves wear resistance. II. Material Removal Mechanism Micro-Cutting Action: Abrasive grains remove material at a micron-level depth, ensuring minimal heat generation and avoiding thermal damage to the workpiece. The large contact area between the abrasive stones and the bore wall results in low unit pressure (typ...
