Makino claims that the DUO wire-cut EDM machine has more than 140 patented technologies. The English meaning of "DUO" is "double", which means that many of the internal structures of the machine are paired, such as double pump system, double guide. Silk system, dual control panel, dual operating mechanism, etc. are the first in the industry.
According to reports, the double guide wire system, which combines the C-type guide and the circular guide, can select the best automatic threading mode according to the aperture and thickness of the specific cutting piece. The fastest automatic threading can be up to 10 seconds, greatly improving the reliability and speed of threading. The C-type guide is a traditional high-precision opening and closing system of Makino. It is an open structure. Even if a mixture is piled up, the guides are not removed when cleaning. The circular guides can automatically superfine the ultra-fine holes arranged at a very small pitch. Threading, achieving the fine conical processing performance of the high-precision stamping die die edge, is very suitable for the precision machining of the main body with a thickness of less than 100mm.
Moreover, in the processing of the cutting line or the end surface with convex and concave, in order to prevent the processing speed from falling and the wire breakage caused by the pressure change, the operator valve needs to be adjusted. After the double water pump system, the processing liquid pressure of the upper and lower nozzles is respectively Independent pumps are independently controlled to eliminate pressure changes and optimize processing conditions.
The high efficiency and low cost of the DUO wire-cut EDM machine are also worthy of attention. Thanks to the changes in the machine structure and the improvement of the machining conditions, the machine can process at a speed of 130mm2/min, which is slower than the current one. The machining speed of the machine is increased by 30% by 100%, and the high-efficiency machining can be performed even when the nozzles are not in close contact with each other, and the time required for the arrangement of the workpiece and the interference check of the nozzles can be saved.
The low use cost is mainly reflected in the amount of wire consumption. Taking 1kgΦ0.3mm copper wire as an example, the workpiece with a thickness of 100mm is processed at the same speed of 1.7mm/min, and the processable length of the conventional slow wire feeder is 294mm. The DUO wire-cut EDM machine can extend this length to 393mm and increase the processing circumference by nearly 30%. Usually, the monthly consumption of copper wire for each slow wire machine is about 150kg. According to 30%, a single machine can save 45kg per month. Makino has emphasized that in the current high copper prices, this will undoubtedly benefit from long-term use for companies with multiple machine tools.
Makino machine tool latest wire cutting EDM machine DUO global listing
On September 3, Makino Machine Tool (China) Co., Ltd. held a global listing ceremony for its newly developed wire-cut EDM machine DUO. The ceremony was held simultaneously in the three places, namely Makino's base in Kunshan, Makino Singapore and Makino. Japan headquarters.
