Five-axis linkage machining center, also called five-axis machining center, is a machining center with high technological content and high precision specially used for machining complex curved surfaces. Instruments, high-precision medical equipment and other industries have a pivotal influence.

Mastering some simple fault detection methods will help to maintain the five-axis machining center in the future, and some problems can be found in time. The following are some five-axis machining center fault detection methods:

Method of measurement

For the convenience of adjustment and maintenance, the numerical control system is generally equipped with measuring terminals for detection when manufacturing printed circuit boards. This equipment can be used to analyze, find and judge faults. Refer to the electrical schematic diagram and the control system. Logical diagrams and other data, along the faulty channel, measure step by step until the fault point is found.

Using the measurement method requires maintenance personnel to have a better grasp of the circuit diagram and logic diagram, and truly understand the actual location of the electrical components, and the use of the measurement method to find faults does not necessarily require measurement from the starting point to the end point, but the optimization method can be used, which can save a lot of money time.

Using the method of checking the parameters

The parameters directly affect the performance of the five-axis machining center. It is the precondition to ensure the normal operation of the machine tool. The reasons for the problems with the parameters are generally as follows. Causes the loss or change of some parameters, and then causes the machine tool to fail to work normally. At this time, as long as the parameters are adjusted and checked in time, the fault can be eliminated; in one case, when the five-axis machining center is idle for a long time, it is also easy to cause For the loss of parameters, the countermeasure is to check and restore the parameters; another situation is that due to the long-term operation of the machine tool, the wear of the mechanical moving parts, the performance of the electrical components has changed, and the parameters have also been adjusted. In this case, it is good to correct the parameters in time.

Method of finding information

When the five-axis machining center fails, you can quickly solve the fault and restore the normal operation of the machine tool according to the self-diagnosis information, alarm information, and the relevant processing methods in the manual. For example, when the memory of the five-axis machining center overflows, You can refer to the relevant manuals, follow the processing steps in the manuals, turn on the read-write switch, delete the contents of the storage, and re-enter the program, and the problem is quickly solved.

Replacement spare parts available

If the five-axis machining center fails and there is no alarm information, in this case, on the basis of roughly analyzing the cause of the failure, use spare printed circuit boards, integrated circuit chips or components to replace the suspicious parts. The advantage is that the fault range can be narrowed down to the printed circuit board or chip, which saves time for fault finding. Now many five-axis machining centers use this method for diagnosis, and then replace the damaged module with spare parts to make the five-axis machining center. The machining center quickly returns to normal operation, but there are several problems that must be paid attention to during the application of this method: first, it must be carried out in a power-off state; second, the version, model, and various marks of the circuit board , The jumper should be the same as the original version. If it is inconsistent, it cannot be replaced. Thirdly, during the process of removing the stitches, you must pay attention to marking and recording. The operation steps of the whole process must be carried out in strict accordance with the operation manual and maintenance book of the system.

Methods that can be used with functional programs

The method of using the function program is an important means to check the working status of the machine tool. For the machine tool that has been idle for a long time or when the machine tool is turned on for the first time, the function program method can be used for a check. How does the functional program test method work? It uses the programming method to compile the G, M, S, T, and F functions of the CNC system into a functional test program, and stores this program in media such as paper tape and magnetic tape. On, when the five-axis machining center fails, this program can be used to quickly determine the cause of the failure.
