First, the pre -tightening of the dual nuts: The round nut of the relative radial area of the 2 nuts is adjusted according to the adjustment method of the relative radial part of the 2 nuts. It is one of the pre -tightening methods.

Second, the dual -nut cushion type pre -tightening: This method is relatively simple and common. It adds a sealing circle in the middle of the double nut. Manufacturers can adjust their pre -tightening force in accordance with customer regulations, and are easy to install and disassemble.

3. Single -snail variable dialing round diameter self -pre -pre -tightening: This type of pre -tightening method is to cause a wire gene mutation in the middle of the nut and thread, so that you can make the tail ball of the ball and the ball. Preview. The roller screws of the CNC processing management center cleared the radial gap, mainly to better improve the precision and bending stiffness of the transmission system.

In the use of mimer and board processing and manufacturing, the characteristics of CNC parts processing are the characteristics of the high and width ratio of automation technology, so that the entire process of Modai processing and manufacturing does not use manpower to operate, greatly saving human resources management and reduced work costs. Although CNC processing technology, although high -width ratio automation technology has reduced the difficulty coefficient of working costs and manufacturing, in addition, compared with traditional technical nature, it must actually operate staff with more technical professional knowledge. In the specific application of CNC processing technology, the data information management system is selected, which intelligently combines the automatic control system and information content. Therefore, the actual operating staff of the CNC machine tool processing technology must be skillfully grasped the actual operation and manipulation of the program process. The level of manipulation and actual operation at the level of electronic computers and CNC lathes is the basic of the quality of decision -making models. Relevant staff only have skilled professional skills to better apply machinery and equipment to give full play to greater economic benefits.
