One is the use of the
Precision Honing feed to a group of honing head body fitted in the stone, a stone exert radial pressure on the workpiece, and the rotary motion and reciprocating motion precision machining method for processing.
Honing stone mounted in a special honing head, driven by the honing honing machine spindle for rotation and reciprocating motion, or a rotating workpiece, honing head is reciprocated by the expansion and contraction mechanism which extends the stone, the bore wall pressure radially expanded for movement, to achieve honing. In order to improve the quality of honing, honing head and spindle are generally floating connection, or rigid connection equipped with a floating jig to reduce honing machine spindle center to be machined hole concentricity error on honing quality.
Not only can be used to bore honing precision machining, and can be used for cylindrical, flat and curved precision machining.
In each reciprocating stroke honing the number of revolutions is a non-integer, so it is the start of each stroke are staggered at an angle with the last, on which the stone grit in the processing of each cutting surface trajectory will not repeat, thus forming a uniform cross honing.
Since having a length Whetstone, Whetstone cutting path of the previous turn in the axial direction there is a duplication, so to ensure the connection between the front and rear cutting path smoother. When the honing head reciprocates in the bore, the same stone as the deck surface of the fight in the processing of high projecting point, under the pressure of the honing, the high point slashing. While the high point on the machined surface passivation also impact on the abrasive, so broken or fall off, and re-exposed Fengrui abrasive. So honing process is also Whetstone constant interplay with the machined surface grinding and finishing, so that the original marks and
Residual stress and deformation layer is rubbed off, hole shape error is corrected. Whetstone accordingly be worn. Converted by a point contact when the two contact surfaces, the pressure per unit area on the honing reduced accordingly, the chip thinning, ravioli of stone begins to be blocked, the cutting action and disappear gradually decreased, the finished surface roughness decreased, honing process into the polishing process to achieve the required size, and finally Whetstone returned.
