0.18mm Molybdenum Wire suppliers in China


TAGUTI Molybdenum Wire

TAGUTI Molybdenum Wire is Chinese time-honored brand. Molybdenum Cutting Wire is used specially in high speed wire cut edm machine, which is invented and applied mostly in China. Almost all high speed wire cut edm machines abroad are imported from China. And only in China and Russia you can find molybdenum ore. But you can only find in China molybdenum wires especially used for wire edm cutting.


Early in 1990s, the founder of TAGUTI, Senior Engineer Zhang Binlong, has put forward a totally different opinion, to change the traditional processing technic from hot drawing into cold drawing. As everyone knows, hot drawn molybdenum edm wire has higher yield, but ductility and strength of extension turn out to be far less than the cold drawn wires. Because heated wires’ inner structure has been broken. This innovation has become the industrial revolution in Chinese EDM field. After presentation of the theoretical embryo, with help of TAGUTI research and development group, this new technology has been realized. And soon after, molybdenum wires of TAGUTI’S own brand has also been built.

During the past two decades, packaging of TAGUTI Molybdenum cutting wire has been reformed twice. Nowadays there are two kinds of packaging boxes. One, which is yellow plus grey, is for sale in domestic market, the other with bright red color is especially for exporting abroad. Molybdenum cutting Wire coil is vacuum packaged with desiccant. This is exclusive in Chinese market. You can only get this considerate service from TAGUTI.

Molybdenum Cutting Wire Breaking Analysis in Wire Cut Machines

In the practice of wire cutting, used metal wires often take place breaking. When operators process the workpieces, molybdenum cutting wire breaking happens. Then in many cases, they can’t find the cause why wires always break in wire cut machines. So the the processing is delayed and wire cutting precision is greatly reduced in some ways. In this paper, take the molybdenum cutting wire as an example, we analyse the common moly wire breakage during the wire edm machine cutting practice.


With the extensive application of wire electrical discharge machine cutting technology, the broken condition of molybdenum cutting wire in the process is paid more and more attention. As to the DK77 series WEDM, the use of molybdenum cutting wire is a case.

In EDM field, we currently use the wire diameter of 0.18mm molybdenum cutting wire widely. But when internship operatots often practice, molybdenum cutting wire  an break out in a very short period of time. It just can not achieve the normal life of molybdenum cutting wire, which will greatly increase the cost of wire cutting, waste of working time and make the processed workpiece being scrapped or the accuracy decline. Through the observation and analysis of the broken wire, we can conclude that molybdenum broken wire can be divided into the following cases:

Normal wire breaking

In the course of common wire use, there will be the continuous loss of metal wire. In this case, molybdenum cutting wire can complete the normal processing quite normally. The wire will gradually become thin, until it reaches the limit size and wire breaks. For the normal use of molybdenum cutting wire on the cartridge, the color is silver. For the unused molybdenum cutting wire which is retained by processing limiter device, the color is bright black.

Abnormal wire breaking



Molybdenum Cutting wire tight wrap, coiling ways and other issues caused by wire breakage.

When producing molybdenum cutting wire, if wire winds too tight, wire would be easy to be pulled  out. So this phenomenon notices us molybdenum cutting wire winding can not be too tight and should tight and appropriate. Tighten wire after the completion of molybdenum cutting wire. The tightness will reflect in the processing. If wrap too loose, molybdenum cutting wire will vibrate sharply that makes workpiece is not enough. And large vibration amplitude will result in molybdenum cutting wire discharge and cause molybdenum cutting wire burnt. If wrap too tight, processing will exceed the tensile limit that molybdenum cutting wire can withstand. Broken wire will also happen.

TAGUTI factory has specialized machines to wrap molybdenum cutting wire well, so it assures the quality stability of molybdenum cutting wires. molybdenum cutting wires are always our hot products. We can ensure the high quality, enough length and warm-hearted after-sale service!

2.2 The choice of coolant liquid on molybdenum cutting wire broken wire

Coolant in the wire cutting process has an important impact on the wire breakage. Coolant materials have many types such as wire cut edm soap, concentrated ointment and coolant liquid. For example, the commonly used coolant is wire cut machine emulsion. When the emulsion is too thin, its ability to eliminate ionization will decline, and even frequently make molybdenum cutting wire and parts short circuit which results in molybdenum cutting wire breaking. When the emulsion concentration increases, its permeability and lubricity will be improved. But the concentration is too large, it will make cooling liquid difficult to enter the cutting part of workpiece, and make the chip processing hard removal which results in molybdenum cutting wire breaking.

In addition, to use coolant for a long period of time but do not replace will lead to increased impurities in the cutting fluid. During the processing, it will invoke molybdenum cutting wire and parts from the secondary discharge which causes by molybdenum cutting wire broken wire. So coolant needs to be replaced frequently when emulsion uses for a long time in the cutting fluid storage tank.

Our hot-sale product is JR-3A WEDM Super Concentrated Ointment Wire Cut Machine Coolant EDM Wire Gel with 9 bottles per box.

2.3 The impact on molybdenum cutting wires caused by positive and negative electrode

In the workpiece processing, it often involves different pulse widths. When the pulse width is within 0.5-100μm, we tend to treat workpiece as positive electrode and molybdenum cutting wires as negative electrode. We make use of negative effect to reduce the loss of molybdenum cutting wire. Instead, when the pulse width is more than 300μm, we tend to treat workpiece as negative electrode and molybdenum cutting wire as positive electrode to save the consumption of molybdenum cutting wires. When the diameter of 0.18mm molybdenum cutting wire in the processing of continuous wear and tear, every 0.01mm diameter of molybdenum cutting wire processes 30000mm ~ 60000m and when its diameter is consumed to 0.11mm ~ 0.12mm, the molybdenum cutting wire will be broken. Thus the choice of positive and negative electrodes can also be effective mitigation for molybdenum cutting wire breakage.

2.4 The workpiece parts and the material itself resulting in broken wire

The material of workpiece will cause a very straightforward and vast impact on molybdenum cutting wire breaking. If workpiece to process contains too much impurities or too rough surface, molybdenum cutting wire is very prone to be broken, as well as when multiple parts overlap clamping, more attention should be paid on the tightness degree of EDM clamping in order to prevent the worlpiece displacement and cut off the molybdenum cutting wire. Besides, too thin or too thick sheet metal parts will make molybdenum cutting wire break. In the processing of parts too thin or a number of thin pieces of superposition, the pulse width can be increased appropriately so that molybdenum cutting wire can stably discharge to reduce the occurrence of wire breakage. And when the workpiece is too thick, due to too long continuous discharge time of molybdenum per unit length, the internal cuttings is not easy to rule out. Therefore we need to increase the wire speed of molybdenum cutting wire to reduce the molybdenum cutting wire breakage.

In the actual processing, the high speed wire-cutting machine faces more diverse as to the reasons for wire breakage. The above suggestions are just a few practical experience in the process of operation. Through continuous attempts and analysis , TAGUTI believe in the future processing, the application of high speed wire cut machine will be more extensive, molybdenum cutting wire life span will be further extended, the workpiece processing quality, processing speed and processing efficiency will be further improved.
