In-depth analysis of the application of automatic CNC lathes. Although there are many types of automatic CNC lathes, they are generally composed of three major parts: the main body of the lathe, the CNC machine tool equipment and the servo control system. Except for a part of economical and practical CNC lathes that basically maintain the traditional and reasonable layout of general lathes, the main body of automatic CNC lathes has been manufactured according to the design plan and the shape of most CNC lathes at this stage.

 1. Spindle CNC lathe spindle's rotation accuracy immediately jeopardizes the production and processing accuracy of the parts; its output power size and rotation rate jeopardize the production and processing, and its simultaneous operation, automatic speed regulation and fixed item stoppage regulations, jeopardize it The level of intelligence of the lathe. The spindle box is equipped with a CNC lathe with fully automatic variable speed function. The transmission mechanism in the spindle box has been greatly simplified. The CNC lathe with stepless fully automatic variable speed has long gone without the organization of gear transmission speed regulation and direction change functions. The headstock has also become a synonym for "bearing with seat" and "lubricating box", and most of its inherent headstock is preserved for the renewal and transformation of CNC lathes.

 2. Slide rail The slide rail of the CNC lathe is the main component to ensure the fitness and movement of the knife. Automatic CNC lathes endanger the bending rigidity, precision and stability of the lathe during low-speed milling at a relatively large level, and are one of the main reasons that endanger the quality of parts processing. Except for some CNC lathes that still use traditional rolling slides, plastic slides have been widely used for CNC lathes manufactured by shaping. This new type of rolling linear guide has low friction resistance, good wear resistance, corrosion resistance and shock absorption, and excellent lubrication standards.

3. In addition to the gear transmission organization of precision CNC lathes, a part of the transmission gears in the spindle box has been removed. Automatic CNC lathes have been greatly simplified based on the original transmission gears of ordinary lathes. For example, the hanging wheel box, the knife box, the slide box and most of the transmission mechanism are cancelled, and only the spiral transmission organization of the longitudinal and horizontal knife is preserved, and the side of the drive motor ball screw is added to exclude it. Worm gear pair with clearance.

 1. The selection of the spindle motor: 1. It should meet the requirements of the cutting amount of the machine tool, the metal material removal rate per unit time, and the low-speed gear and large torque of the spindle; 2. The motor output power calculated according to the specified spindle acceleration/deceleration time should not be high Due to its maximum power; 3. The average power calculated from the place where the spindle is frequently started and the braking system should not exceed its continuous rated power; 4. The steady speed control place, the cutting amount required for steady speed, the output power and the speed required The sum of the output power should be within the range of the output power that the motor can bring. As a key type of industrial master machine, CNC lathe is the same as other types of machine tools. Its production and processing accuracy index value is its main performance parameter. The key difference between Chinese digital control lathes and global CNC lathes is also reflected in the production and processing accuracy. The fundamental difference between my country's machine tool field and the machine tool field of prosperous countries such as Europe, America and Japan is that the accuracy of lathes does not meet the user's requirements, which is mainly manifested in accuracy reliability and accuracy maintenance.
