Selection and Optimization of Temperature Measurement Points of Li Dexin Saw Blade Grinding Machine

 

 

 

    In order to find out the temperature field of the gear grinding machine during long-term production and processing, a large-scale CNC forming gear grinding machine is taken as the research object. According to its structural characteristics and the temperature rise of the moving parts, 26 main heat-receiving parts of the machine tool are set. Temperature Sensor. Since the relative position error Δz of the grinding wheel and the workpiece along the machine tool coordinate Z direction during the forming grinding process only affects the position of the tooth surface on the circumference of the gear, it does not have any influence on the tooth surface itself.

 

    In addition, the influence of the position error of the grinding wheel and the workpiece axis along the X direction of the machine coordinate system on the machining accuracy of the gear is particularly obvious. Therefore, the respective laser displacement sensors A and B are respectively mounted at the radial positions of the detecting grinding wheel and the workpiece shaft, and the measured displacements are Δxw and Δxg, respectively.

 

    The gear grinding machine has complex structure and many heat sources. The interaction between the heat sources will cause the variable coupling relationship between the various temperature variables in the thermal error compensation model of the machine tool, thus reducing the accuracy and robustness of the compensation model. In this regard, according to the basic principle of fuzzy clustering method, the correlation between the machine tool temperature and the corresponding displacement variable is firstly analyzed, and the correlation coefficients between multiple temperature-displacement variables are classified into one class; then the correlation coefficient is selected from which the correlation coefficient is large. The temperature variable is represented by this class; at the end of Zui, each temperature variable is represented as a temperature variable group for the thermal error modeling of the gear grinding machine.

What is the thickness of the particle size of the Li Dexin saw blade grinding machine?

 

    What is the thickness of the grain of the gear saw blade? If the machining process adopts the upper and lower cutting mode, the initial contact surface of the single crystal particles of the high speed steel saw blade can reach the thickness of the large particle tip of the Zui. Conversely, while maintaining the up and down mode, the diamond particle thickness increases to a large value of zoi during processing.

 

    In this condition, the tensile deformation of the diamond particles mainly occurs in the initial stage of Zui, and Zuijia is suitable for the thickness of the tip of the particle to be reached and formed. The upper and lower cutting modes show distinct grinding characteristics. During the lower cutting process, high mechanical shock pulses occur in view of the type of abrasive and bonding agent and, like diamond cracking or exposure. In the upper cutting mode, the thickness of the diamond tip increases from zero to large. At the beginning, only the tip of the diamond contacts the stone. After the Zui, the diamond particles are contacted with the ground and polished diamond particles. We have also reported this in our customer feedback. During the cutting process, the fracture of the sedimentary rock is closely attached to the bottom of the diamond particles, mainly because of the low strength of the high-speed steel saw blade bonding material. Small pieces and high hardness stone chips appear after the cutting process.
