Introduction to automatic hydraulic lathe frequency converter

Fully automatic machine

Automatic hydraulic lathe in the hydraulic machine industry, the use of frequency converter scale. However, Japan's yaskawa, Fuji, mitsubishi and Taiwan's delta and other brands occupy a larger market share. Although also have a few homebuilt brand inverter is chosen by machine tool manufacturing enterprise, but in grinder, forging press machine tool wait for the domain with taller to inverter industry function entreat, as usual it is foreign brand is in the majority, be like mitsubishi, Fuji, German Siemens, delta wait for a brand to be in advantage as usual. According to 2008, 2009 machine tool sales data flash, universal machine tools, especially complex function of the lathe inventory situation is serious, and complex machine tools, large heavy products market is better. These machine tools processing scale is wide, the implementation of machine tools components have strange activity speed, the inverter function also put forward a higher request, domestic inverter manufacturers should seize the opportunity to cultivate the machine tool market.

With the development of frequency converter technology, its application in machine tool industry is developing continuously.

The opening trend of the inverter for automatic hydraulic lathe is shown as follows:

One is high performance. At present, all inverters require vector control methods, and there are a few different levels of control structure and algorithm. It is worth noting that speed sensorless vector control (SVC) is opening faster in recent years, because SVC can plead low interest, high function of the disposal plan, formerly became the dream of universal inverter specifications and open direction.

Second, easy to control from time to time forward. The user's demand for frequency converters is gradually transformed into field devices, and additional Settings are added to the software, so as to simplify the debugging process after the user's operation.

Third, the function of modular and intelligent demand gradually rising. It is understood that a machine tool with the number of frequency converter some up to 4-5. This is enough to foresee the market potential of machine tool inverters.
