Most CNC machine tools have their own automatic locking function when they leave the factory. According to the survey in real work, most CNC machine tools have their own automatic locking function when they leave the factory. Just analyze the data. The situation we understand is: Because most CNC machine tools are expensive, ranging from hundreds of thousands to hundreds of thousands, or even millions, when we buy machine tools, we don’t have that much money, so what should we do? ? Therefore, there is a mortgage. After the down payment is paid, the machine tool can be taken home. After the buyer repays the loan on time, the seller will send an unlock code to unlock it. If the repayment is not completed on time, the machine tool It will be automatically locked within the set time (of course, the machine tool will not be locked suddenly during work, but after a certain part is processed, or the next day, the machine tool system will be locked and unable to work).
How is this automatic locking function realized?
There are two popular sayings in the industry: some people say that a GPS positioning module is installed, and some people say that a gyroscope or a level gauge is installed. When the device senses that the machine shakes more than a certain angle, the system will be locked and a password is required to unlock it.
The machine tool is installed indoors. High-precision equipment may even be separated. The poor GPS signal becomes commonplace. If the GPS signal is not available during installation, it will be a nightmare for the manufacturer. Generally, stable positioning can only be done in places with good outdoor signals. Indoor auxiliary positioning needs to be carried out through mobile communication base stations. Therefore, machine tool manufacturers will not use untrusted communication positioning methods. It needs to be verified whether this is very simple. Buying a signal jammer can shield the base station communication, the machine tool will definitely not be locked, and the manufacturer will not be stupid enough to rely on this kind of thing.
Therefore, the installation of a gyroscope or an electronic level is the real reason why the machine tool can realize the automatic locking function. It is not ruled out that a very small number of machine tool manufacturers with technical strength have joined the GPS communication module, but it is not the mainstream after all.
