Alat mesin pengolahan kawat anu gancang-gancang nyaéta listrik aslina ngolahnaalat mesin di nagara kuring. Saatos puluhan taun pamutahiran kontinyu sarengpamekaran, it has now become an important ngolahna method in the manufacturing industry. It can meet the requirements of middle and low-end mold ngolahna and other complex parts manufacturing, and occupies a considerable weight in the middle and low-end market.
The biggest advantage of fast-moving wire ngolahna machine tools is that it has a good pagelaran-to-price ratio. Because of its practicability and economy, it has a larger market in China. Traditional fast-moving wire ngolahna uses a one-time cutting process, the ngolahna efficiency is about 40 mm²/min, the surface roughness is about Ra3.0μm, the surface has more obvious lines, and the ngolahna accuracy is about 0.02 mm.
In order to improve the ngolahna quality, manufacturers of fast-moving wire ngolahna machine tools improved the relevant parts of the machine tool by referring to the multiple cutting process, and the so-called "middle wire-moving machine tool" appeared. The numerical control precision of the machine tool, pulse power supply, wire feeding system, and process database have been greatly improved. Improve the ngolahna accuracy and improve the surface quality.
The current technical indicators of the middle wire ngolahna machine tool: the efficiency of one cut is 180mm²/min, the surface roughness after multiple cuts is Ra≤1.0μm, the average efficiency at this time is 50mm²/min, and the processed surface is glossy There is no obvious cutting stripes, the ngolahna accuracy is 0.01 mm, and the electrode wire loss is less than 0.01 ㎜ /200,000 ㎜². These pagelaran indicators seem to be quite good, but it should be noted that obtaining these indicators needs to ensure that all links are well. Once there are discrepancies, such as changes in the concentration of the working fluid and the loss of the electrode wire, the stability of the ngolahna quality will be affected.
