随着机械工业的发展,对螺纹件的精度要求越来越高。如何提高螺纹的加工精度,是必须解决的重要课题之一。在螺纹磨床上磨削螺纹是目前加工高精度、高光洁度螺纹比较理想的切削方法。方牙螺纹的加工,一般采用成型砂轮磨削。由于成型砂轮修整器结构上的缺陷,产生齿形直线性误差,齿形中部呈鼓形。此外,砂轮安装是按照零件中径螺旋升角倾斜的,根据螺旋角的计算公式,在螺旋角大于3°情况下,
With the development of machinery industry, the accuracy of the threaded parts is getting higher and higher. How to improve the machining accuracy of the thread is one of the important topics that must be solved. Grinding thread on the thread grinder is the ideal cutting method for machining high-precision and high-finish thread. Square tooth thread processing, the general use of grinding wheel molding. Due to the structural defects of the forming wheel dresser, there is a linear error of the tooth profile, and the central part of the tooth profile is drum-shaped. In addition, the installation of grinding wheel is according to the diameter of the part spiral pitch angle, according to the helix angle of the formula, the helix angle is greater than 3 °,
