通道(dao)侗族(zu)自治機床(chuang)齒條(tiao)激(ji)光切割(ge)機領域：選用研磨(mo)級精(jing)(jing)密齒條(tiao)，所有表面磨(mo)削(xue)加工齒條(tiao)，滲碳淬火精(jing)(jing)密齒輪(lun)，定(ding)位(wei)精(jing)(jing)度(du)(du)小于0.03mm，移動速度(du)(du)150m/min。

為 齒(chi)數x模數 基準節(jie)線(Standard Pitch Line)：齒(chi)條(tiao)(tiao)上一(yi)條(tiao)(tiao)特定(ding)(ding)節(jie)線或沿此線測定(ding)(ding)之(zhi)齒(chi)厚，為節(jie)距二分之(zhi)一(yi)效(xiao)果(guo)節(jie)圓(yuan)(Action Pitch Circle)：一(yi)對正齒(chi)輪咬(yao)合效(xiao)果(guo)時，各有一(yi)相(xiang)切做翻滾(gun)圓(yuan)。

齒(chi)條的(de)主要特點(dian)由于齒(chi)條齒(chi)廓(kuo)為直(zhi)線，所以齒(chi)廓(kuo)上各點(dian)具(ju)有(you)相(xiang)同(tong)(tong)的(de)壓(ya)力角，且等于齒(chi)廓(kuo)的(de)傾(qing)斜角，此角稱為齒(chi)形(xing)角，標準值為20°。與齒(chi)頂線平行的(de)任一條直(zhi)線上具(ju)有(you)相(xiang)同(tong)(tong)的(de)齒(chi)距和模數。
