Generally speaking, the NC cutting including fast (in) wire processing and wire processing, they are widely used in mold manufacturing industry. What are the current developments in the processing efficiency, cutting accuracy, and surface quality of these two technologies?

Development status of fast moving wire processing technology

The fast wire processing machine is the original electric machining machine tool in our country. After decades of continuous improvement and development, it has become an important processing method in the manufacturing industry. It can meet the requirements of medium and low mold processing and other complex parts manufacturing, and occupy a considerable proportion in the mid and low market.

The biggest advantage of the fast wire processing machine is its good performance price ratio. Because of its practicability and economy, there is a big market in china. The traditional wire speed processing using a cutting process, the machining efficiency of 40 mm in about 2/min, the surface roughness of Ra3.0 m, the surface has obvious lines, about 0.02 mm in precision machining.

In order to improve the quality of the processing, the rapid processing machine tool manufacturers refer to many cutting process, improve the machine tool related parts, appeared the so-called "walking wire machine"". CNC machining accuracy, pulse power supply, wire system, process database and a large number of process technology has been greatly improved. The machining accuracy is improved and the surface quality is improved.

Now go wire machine technical indicators: a cutting efficiency of 180 mm 2/min, the surface roughness after repeatedly cutting for Ra less than 1 m, the average efficiency of the 50 mm 2/min processing, surface gloss no cutting stripes and machining accuracy of 0.01 mm, 0.01 mm less than wire loss /20 million 2 mm. These performance indicators seem to have been quite good, but note that these indicators need to ensure that each link, once the entry, such as loss of concentration, the wire electrode working fluid changes, stability will influence the quality of products.
