Title (EN) DIAMOND SPECIAL-SHAPED GRINDING WHEEL AND VERTICAL MACHINING COOLING SYSTEM
(FR) MEULE DIAMANTÉE DE FORME SPÉCIALE ET SYSTÈME DE REFROIDISSEMENT POUR USINAGE VERTICAL
(ZH) 一种金刚石异形砂轮及立式加工冷却系统
Abstract:
(EN) A diamond special-shaped grinding wheel, comprising an upper base body (201), a lower base body (202), and a grinding ring (203). The upper base body is disposed at the upper end of the lower base body, and the upper base body and the lower base body are fixedly connected to form a grinding wheel body. The grinding ring is fixed to an outer ring of the grinding wheel body; the grinding wheel body is internally provided with one or two annular grooves (204) communicated with the upper end face of the grinding wheel body. A plurality of mixed flow channels (4) sucking in cooling water, powder and air are formed in the grinding ring. One end of each mixed flow channel extends to an annular grinding opening of the grinding ring, the other end is communicated with one annular groove, and the annular grooves are communicated with an external negative pressure air source device. Also disclosed is a vertical machining cooling system. The special-shaped grinding wheel and the cooling system can make cooling water form a coating water film on the working face of the diamond special-shaped grinding wheel, so that the cooling effect is improved, and the usage quantity of the cooling water is reduced. Frictional heat is reduced, the protrusion height of diamond is also ensured, the grinding ability of the grinding wheel can be improved, and the grinding wheel adapts to efficient machining.
(FR) L'invention concerne une meule diamantée de forme spéciale, comprenant un corps de base supérieur (201), un corps de base inférieur (202) et une bague de meulage (203). Le corps de base supérieur est disposé à l'extrémité supérieure du corps de base inférieur, et le corps de base supérieur et le corps de base inférieur sont reliés de manière fixe pour former un corps de meule. La bague de meulage est fixée à une bague extérieure du corps de meule ; à l'intérieur du corps de meule se trouvent une ou deux rainures annulaires (204) en communication avec la face d'extrémité supérieure du corps de meule. Une pluralité de canaux d'écoulement (4) mélangés qui aspirent de l'eau de refroidissement, de la poudre et de l'air sont formés dans la bague de meulage. Une extrémité de chaque canal d'écoulement mélangé s'étend jusqu'à une ouverture de meulage annulaire de la bague de meulage, l'autre extrémité est en communication avec une rainure annulaire, et les rainures annulaires sont en communication avec un dispositif de source d'air à pression négative externe. L'invention concerne également un système de refroidissement pour usinage vertical. La meule de forme spéciale et le système de refroidissement peuvent amener de l'eau de refroidissement à former un film d'eau de revêtement sur la face de travail de la meule diamantée de forme spéciale, ce qui permet d'améliorer l'effet de refroidissement et de réduire la quantité consommée d'eau de refroidissement. La chaleur de frottement est réduite, la hauteur de saillie du diamant est également assurée, la capacité de meulage de la meule peut être améliorée et la meule s'adapte à un usinage efficace.
(ZH) 一种金刚石异形砂轮,包括上基体(201)、下基体(202)和磨环(203),上基体置于下基体的上端,且上基体和下基体固定连接构成砂轮本体;磨环固结在砂轮本体的外圆环上;砂轮本体内设置有一个或两个与其上端面连通的环形槽(204);磨环内设置有吸入冷却水、粉屑及空气的多个混流通道(4),每一混流通道的一端延伸至磨环的环形磨削口处,另一端与一环形槽连通,且该环形槽与外部负压气源装置连通。以及一种立式加工冷却系统。上述异形砂轮和冷却系统能使冷却水在金刚石异形砂轮工作面形成水膜包裹,提升冷却效果,降低了冷却水的用量;既降低了磨擦热,又确保了金刚石的出刃高度,可提高砂轮的磨削能力,进而适应高效加工。
