砂轮平衡支架是磨床配备的附件，用它可以静平衡砂轮，以达到正确使用砂轮的目的，加水平仪还可以检测jingmi工件的静平衡。
砂轮平衡支架选用材料作平衡轴，经热处理以及jingmi的加工与装配故而精度高，性能稳定是一理想的机床附件。
砂(sha)(sha)(sha)(sha)(sha)轮(lun)(lun)平(ping)(ping)(ping)(ping)衡(heng)(heng)(heng)支(zhi)(zhi)架的(de)(de)(de)(de)使用：将砂(sha)(sha)(sha)(sha)(sha)轮(lun)(lun)装在平(ping)(ping)(ping)(ping)衡(heng)(heng)(heng)心轴(zhou)上(shang)，然后(hou)把(ba)装好心轴(zhou)的(de)(de)(de)(de)砂(sha)(sha)(sha)(sha)(sha)轮(lun)(lun)平(ping)(ping)(ping)(ping)放到砂(sha)(sha)(sha)(sha)(sha)轮(lun)(lun)平(ping)(ping)(ping)(ping)衡(heng)(heng)(heng)支(zhi)(zhi)架的(de)(de)(de)(de)平(ping)(ping)(ping)(ping)衡(heng)(heng)(heng)导(dao)轨上(shang)，砂(sha)(sha)(sha)(sha)(sha)轮(lun)(lun)会作(zuo)来回摆(bai)动(dong)，直(zhi)(zhi)至摆(bai)动(dong)停(ting)止。平(ping)(ping)(ping)(ping)衡(heng)(heng)(heng)的(de)(de)(de)(de)砂(sha)(sha)(sha)(sha)(sha)轮(lun)(lun)可以(yi)在任意(yi)位(wei)置(zhi)(zhi)都静止不(bu)动(dong)。如(ru)果(guo)砂(sha)(sha)(sha)(sha)(sha)轮(lun)(lun)不(bu)平(ping)(ping)(ping)(ping)衡(heng)(heng)(heng)，则(ze)其较重部分总是(shi)转到下面，这时可移动(dong)平(ping)(ping)(ping)(ping)衡(heng)(heng)(heng)块(kuai)的(de)(de)(de)(de)位(wei)置(zhi)(zhi)使其达到平(ping)(ping)(ping)(ping)衡(heng)(heng)(heng)。平(ping)(ping)(ping)(ping)衡(heng)(heng)(heng)好的(de)(de)(de)(de)砂(sha)(sha)(sha)(sha)(sha)轮(lun)(lun)在安(an)装至机床(chuang)主轴(zhou)前先要进(jin)行(xing)裂纹(wen)(wen)检(jian)查，有(you)裂纹(wen)(wen)的(de)(de)(de)(de)砂(sha)(sha)(sha)(sha)(sha)轮(lun)(lun)禁止使用。安(an)装时砂(sha)(sha)(sha)(sha)(sha)轮(lun)(lun)和法(fa)兰之间(jian)(jian)(jian)应垫上(shang)0. 5—1mm的(de)(de)(de)(de)弹性(xing)垫板：两(liang)法(fa)兰的(de)(de)(de)(de)直(zhi)(zhi)径相等，其尺寸一般为砂(sha)(sha)(sha)(sha)(sha)轮(lun)(lun)直(zhi)(zhi)径的(de)(de)(de)(de)一半.砂(sha)(sha)(sha)(sha)(sha)轮(lun)(lun)与砂(sha)(sha)(sha)(sha)(sha)轮(lun)(lun)轴(zhou)或台阶法(fa)兰间(jian)(jian)(jian)应有(you)一定间(jian)(jian)(jian)隙，以(yi)免(mian)主轴(zhou)受热膨(peng)胀而把(ba)砂(sha)(sha)(sha)(sha)(sha)轮(lun)(lun)胀裂。
