Metal grinding block for stone polishing and manufacturing method thereof

The invention relates to a diamond tool and provides a metal grinding block for stone polishing and a manufacturing method thereof. According to the metal grinding block for stone polishing, a pore-forming material is fed in a matrix to reduce the abrasion resistance lower limit of the matrix, so that the diamond lip exiting efficiency is improved during the polishing process while effectively enhancing the holding force to the diamond from the matrix, and long service life, a high sharpness and high grinding effect are effectively realized; and in addition, equipment pressure does not need tobe additionally added, the requirement for polishing equipment is reduced, and the polishing cost and energy consumption are reduced. 本发明涉及一种金刚石工具，提供一种石材抛光用金属磨块及其制作方法，所述石材抛光用金属磨块在胎体中引入造孔材料以降低胎体的耐磨度下限，以在有效增强胎体对金刚石把持力的同时，提升抛光过程中金刚石的出刃效率，有效实现了长寿命、高锋利度、高磨削效果，同时无需另外增加设备压力，抛光设备要求降低，降低了抛光使用成本和能耗。
