First, the principle of honing
Honing Process a low grinding method, commonly used in the bore surface finishing, finishing. Honing stone honing head mounted on a special honing machines, honing machines driven by the spindle honing head rotating and reciprocating motion, and through expansion and contraction mechanism which makes Whetstone stretched, to put pressure on the cell wall for feed movement to achieve honing processing. In order to improve the quality of honing, honing head and shaft are generally floating connection, or with a rigid connection with a floating jig to reduce honing machine spindle turning centers and machining affected hole concentricity error of honing quality.
Second, honing Features 1. Good surface quality characteristics honing can get a lower surface roughness, generally up Ra0.8-0.025um. While in favor of a uniform cross-textured oil sump lubrication on honing surface. 2 high precision honing process can not only obtain high dimensional accuracy, but also a slight shape error correction holes appear before the honing processing, such as roundness, cylindricity and surface waviness and the like. 3 honing efficiency, or you can use multiple superabrasive Whetstone Whetstone, can quickly remove the honing and hole shape error margin, effectively improve the efficiency of honing. 4 hole honing process more economical and less rigid thin-walled workpieces, or hard surface and irregular shape of the hole, may be finishing by honing, without complex equipment and tooling, easy to operate.
Third, the scope of application of a widely used honing various shapes hole finishing or finishing degree domestic honing machine working range: Aperture: Φ3-Φ250mm hole length:. 3000mm 2 apply to liner hole, connecting rod. hole, hydraulic pump nozzle and valve hole, rocker, holes and other gear batch processing. 3 for metallic materials and processing of non-metallic materials such as cast iron, hardened and not hardened steel, hard aluminum, bronze, brass, hard chrome and carbide, ceramics and sintered materials.
