圆锥管螺纹环规是检验锥度螺纹的专用量具。通常螺纹齿形的精加工工艺有两种,一种是1/2″～2″范围内由螺纹磨床加工,另一种是1/8″～3/8″范围内由研磨加工。1/2″～2″环规由于尺寸大,加工工艺性好,一般来讲,螺纹磨床的磨削精度能达到图纸要求,而1/8″～3/8″环规由于尺寸小,精度要求高,加工工艺性差,制造相当困难。为此,我们设计制造了圆锥管螺纹沉割复合丝攻,改进了加工工艺,保证了沉割与齿形对称,为研磨螺纹齿形创造了优良条件,使1/8″～3/8″小尺寸范围内的圆
Conical pipe thread ring gauge is a special measure of taper thread. There are usually two kinds of finishing process of thread profile, one is from 1/2 “~ 2” by thread grinder and the other is 1/8 “~ 3/8” by grinding. 1/2 “~ 2” Ring Gauge Due to its large size and good processing technology, the grinding precision of thread grinder can meet the requirements of drawing. Generally, the 1/8 “~ 3/8” ring gauge has the advantages of small size, High demand, poor processing technology, manufacturing very difficult. To this end, we designed and manufactured a cone pipe thread cutting complex wire tapping, improved processing technology, to ensure that the cutting and symmetry of the tooth, grinding teeth for the tooth to create a good condition, so that 1/8 “~ 3/8” Small size range of the circle
