The fast wire cutting machine is very Chinese, has the characteristics of simple structure, low price and convenient use, and is suitable for workpiece processing with low precision and smoothness. The console is generally divided into two types - computer control and single board machine, each with its own characteristics, computer control is relatively intuitive, single board machine has low failure rate and easy maintenance, but the computer console is also very easy to use if it is industrial design. Brands like Su Sanguang, but in fact, some manufacturers use home computers as consoles, can not withstand the humidity, dust and electromagnetic interference at the production site, and even frequent failures; single-board machines are designed according to industry standards. Suitable for harsh working environments and cost-effective, so the market demand is still very large.
The use of a single-board console often encounters a technical problem of program transfer. The parallel communication port is prone to interference errors when transmitting the program, often damages the computer and the machine console, cannot be sent over long distances, etc. The program is slightly longer. For a long time, the more complicated workpiece program can not complete the transmission, which seriously affects the order of production. Therefore, a dedicated peripheral device, the wire cutting program transmitter, is needed.
There are a few questions to be aware of how to purchase a program transmitter:
First, make sure that your single board communication port is a photoelectric interface. If it is, the transmitter may not be suitable or need to be modified, but there are few such types, and the transmission program will not be problematic;
Second, the program transmitter should be a passive output body:
Passive is a professional predicate, that is, the output can not have voltage, can also be seen as multiple sets of electronic switches that switch on and off with the data signal; another function of the product is electrical isolation, otherwise, different devices There is still electricity connection, there are still risk factors for burning due to electromagnetic interference, equipment failure, power supply instability, etc. If some products claim to have signal amplification, they can be directly compatible with single-board machines with optocoupler interfaces. That is nonsense;
Third, the most important thing about the transmitter is its versatility:
Since the communication ports defined by each machine tool manufacturer are different, the response type communication is like Ningbo machine, the synchronous type communication has Shenzhen machine, the telegraph head communication has Su Sanguang, the suspended type input has Shanghai Zhaoming machine and Su Changfeng; There are problems such as response time, non-standard communication level and high and low level of strobe signal. Moreover, customers often use wire cutting machines from different manufacturers, so the compatibility of the transmitter is very important. At present, there are such products on the market, but only for specific models, such as Su Sanguang's communication adapter, the response time is fast, the performance is very good, but it is not universal, only the machine tool of our factory is applicable.
