Diamond honing oil stone for processing reticulate patterns on platform of cylinder sleeve and preparation method thereof

Abstract

The invention discloses a diamond honing oil stone for processing reticulate patterns on the platform of a cylinder sleeve and a preparation method thereof. The diamond honing oil stone is characterized by being prepared by the following materials in percentage by weight: 50 to 88 percent of CuSn10 bronze powder, 5 to 20 percent of iron powder, 5 to 20 percent of nickel powder and 2 to 10 percentof artificial diamond, wherein the CuSn10 bronze powder, the iron powder and the nickel powder are used for preparing a metal bonding agent material, and the particle size of the artificial diamond is 100 to 320 meshes. The preparation method comprises the following steps of: mixing the raw materials; performing cold-press molding; and performing a vacuum hot-pressing process to obtain the honingoil stone. By the oil stone and the preparation method, the problems that the honed reticulate patterns cannot meet relevant indexes of cylinder sleeves in Euro III and Euro IV emission standards dueto inconsistent depths and widths at the stage of processing the reticulate patterns of the cylinder sleeve by using the honing oil stone in the prior art are solved.

Description

technical field [0001] The invention relates to a honing oil stone used on a honing machine, in particular to a diamond honing oil stone used for processing cylinder liner platform texture and a preparation method thereof. Background technique [0002] The cylinder liner is a key part of the internal combustion engine. The inner surface of the cylinder liner together with the top of the piston, the piston ring and the bottom surface of the cylinder head constitute the combustion chamber of the engine. The quality of its processing directly affects the assembly performance and service performance of the engine. [0003] Before honing, the cylinder liner needs rough boring, semi-fine boring and fine boring; the honing process is rough honing, fine honing and platform anilox honing in sequence. The so-called platform texture honing process refers to the use of rough honing to form a visible uniform, symmetrical and continuous cross pattern on the processed surface, and at the s...
