导读：众所周知，砂轮是磨削加工中最主要的一类磨具。砂轮是在磨料中加入结合剂，北京广宇大成数控机床有限公司,广宇大成数控机床,经压坯、干燥和焙烧而制成的多孔体。由于磨料、结合剂及制造工艺不同，砂轮的特性差别很大，因此对磨削的加工质量、生产率和经济性有着重要影响。万贯五金机电网小编为大家介绍砂轮的特性主要是由磨料、力度、结合剂、硬度、组织、形状和尺寸等因素决定。磨床上用砂轮特点是：由于剧烈的磨擦，而使磨削区温度很高。这会造成工件产生应力和变形，甚至造成工件表面烧伤。因此磨削时必须注入大量冷却液，以降低磨削温度。冷却液还可起排屑和润滑作用。 　　记者日前从有关方面了解到,作为广州机床工具行业协会常务副会长企业,广州市敏嘉制造技术有限公司2012年在专用数控磨床行业取得重大突破:敏嘉首次作为责任单位,承担了国家高档数控机床和基础装备重大专项:“弧面凸轮加工工艺研究及弧面凸轮五轴加工中心、弧面凸轮六轴磨削中心”。该项目的目标是研究刀库换刀机构弧面凸轮加工工艺,开发具有自主知识产权的弧面凸轮制造专用设备,满足功能部件企业需求,提升国产刀库设计制造水平。 　　城市轨道交通方面，根据国务院批准的第一批城市轨道交通项目规划，至2015年的规划线路长度是2400km，投资规模近7000亿元，截至2008年11月已完成了1000亿元投资。城市轨道交通的大规模建设和规划，必将带动机床加工机床的需求增加，如大型铣床、磨床、重型机床等加工设备。以高速和提速、重载为重点的中国铁路建设与改造，已经步入了发展的“快车道”。轨道交通业对机床的需求是多方位的。一个是机车(电力机车和电传动内燃机车)和车辆制造。
