金刚砂磨削时要注意的地方,河南强力砂带专用砂厂家

价 格:面议

金刚砂又名碳化硅,石头粉碎机,在其中分类上主要分黑碳化硅和绿碳化硅,其中:黑碳化硅是以石英砂,石油焦和优质硅石为主要原料,通过电阻炉高温冶炼而成。其硬度介于刚玉和金刚石之间,机械强度高于刚玉,性脆而锋利。绿碳化硅是以石油焦和优质硅石为主要原料,添加食盐作为添加剂,通过电阻炉高温冶炼而成,石料生产线。其硬度介于刚玉和金刚石之间,机械强度高于刚玉。常用的碳化硅磨料有两种不同的晶体,一种是绿碳化硅,含SiC 97%以上,主要用于磨硬质含金工具。

注意的地方:

1、树脂结合剂金刚砂砂轮结合强度弱,因此磨削时自锐性能够好,不易堵塞、磨削效率高、磨削力少、磨削温度低,缺点是耐磨性较差、磨具损耗大,不适合重负荷磨削。

陶瓷结合剂金刚砂砂轮耐磨性及结合能力优于树脂结合剂,切削锋利、磨削效率高、不易发热及堵塞、热膨胀量少、容易控制精度、缺点磨削表面较粗、成本较高。

金属结合剂金刚砂砂轮结合强度高、耐磨性好、磨损低、寿命长、磨削成本低、能承受较大负荷,但锐性差,易堵塞。

供应耐磨地坪专用金刚砂

2、磨料粒度对砂轮堵塞及切削量有一定影响,粗砂粒与细砂粒相比,切入深度大磨粒切刃磨损增大,反之砂轮易于堵塞。
