At present, domestic CNC lathe systems are becoming more and more high-tech. CNC systems include open-loop servo systems, closed-loop servo systems, semi-closed-loop servo systems and CNC servo systems. The mechanical structure of the feed system of domestic CNC machine tools is very different from that of ordinary machine tools, which is reflected in the use of precision ball screw pairs, gap elimination mechanisms, and precise guide rails (such as linear guide rails, hydrostatic guide rails, plastic guide rails, etc.) wait). The position detection device is the key to ensure the accuracy of closed-loop and semi-closed-loop servo systems. Commonly used position detection devices include resolvers, inductive synchronizers, gratings, and magnetic gratings.

　　The spindle drive mode of the CNC system includes variable speed gear transmission, belt drive, two motors to drive the spindle respectively, and a built-in spindle motor. There are motor speed regulation and mechanical gear speed regulation for spindle speed regulation. In order to meet the needs of low-speed and powerful cutting of CNC machine tools, the method of segmented stepless speed change is often used.

　　How to operate the domestic CNC lathe system?

　　1 How to restore the factory value of the parameter

　　The function of restoring the factory value of the parameter is to restore the parameter currently used by the system of the specified parameter to the parameter set by the factory.

　　This function is mainly used when the parameters of the CNC system are confused and the system cannot work normally. The factory value of the parameters can be guaranteed

　　The normal operation of the system may not meet the user's specific needs, so the user should execute this function with caution. In order to prevent no

　　The operation requires a password to be entered before the operation.

　　Steps to restore factory defaults:

　　(1) Enter the factory default interface,

　　(2) Press F7 (input password), enter the correct password, and then press ENTER;

　　(3) Use the cursor keys ← and → to move the large cursor to the column where "current parameter" is located, and then use the cursor keys ↑ and ↓ to move to the desired

　　The line where the parameter to restore the factory value is located;

　　(4) Press F1 (factory value), if the operation is successful, the status bar will prompt: "Restore factory value completed!", otherwise it will prompt "Restore factory value error!".

　　2 How to backup parameters

　　The main function of backing up parameters is to protect the parameters from data loss, and the parameter backup files will not be affected by the formatting of the electronic disk.

　　Therefore, it is recommended that users make a backup of the parameters that meet their own operating requirements in the CNC system, so that they can be saved at any time when the parameters are wrong.

　　recovery. The CNC system provides two storage spaces for each parameter, "Backup 1" and "Backup 2".

　　Steps to backup parameters:

　　(1) Enter the factory default interface,

　　(2) Press F7 (input password), enter the correct password, and then press ENTER;

　　(3) Use the cursor keys ← and → to move the large cursor to the column where "Backup 1" or "Backup 2" are located, indicating that the
