Pay attention to the maintenance of the protective cover of the CNC machine tool

Relying on science and technology to develop products to make the company full of vitality, users all over the country and abroad, is one of the largest domestic companies in the same industry with an earlier production history of machine tool accessories and protective devices, strong professionalism, and strong technical force.

1. Intuitive method: The maintenance personnel carefully observe various parts of the system through observation of various light, sound, smell and other abnormal phenomena when the fault occurs, and narrow the fault range to a module or a printed circuit board.

2. Self-diagnosis function method: The self-diagnosis function of the numerical control system of the machine tool guard has become an important index to measure the performance characteristics of the numerical control system. The self-diagnosis function of the numerical control system monitors the working status of the numerical control system at any time. (Guide: Introduction to the aluminum profile spraying process)

3. Function program test method: The function program test method is to program the common functions and special functions of the CNC system into a function test program by manual programming or automatic programming, send it to the CNC system, and then let the machine tool guard cover The numerical control system runs this test program to check the accuracy and reliability of the machine tool to perform these functions, and then to determine the possible cause of the failure.

4. Exchange method: The so-called exchange method of the machine tool guard is to use spare printed circuit boards, templates, integrated circuit chips or components to replace the suspected parts in the case of analyzing the general cause of the failure, thereby reducing the scope of the failure Reduce to the level of printed circuit boards or chips.

Fifth, principle analysis method: According to the principle of CNC composition, logically analyze the logic level and characteristic parameters of each point, analyze and judge from the working principle of each component of the system, and determine the repair method of the fault location.

6. Parameter inspection method: When the CNC system finds a fault, it should check the system parameters in time. The change of the system parameters of the machine tool guard will directly affect the performance of the machine tool, and even make the machine tool unable to work normally.
