FAQ

  1. What is the consumption of your Electrode?

    The comsumption of Our Electrode can be below 1.0kg/mt, and the everage is 0.5kg/mt.

  2. What is the reason of the problem of broken?

    There are several reasons, such as: Amperage is too high, the connection is not good, etc.

Q:What is the application of wire cutting with graphite electrode?
With the development of science and technology, the machine manufacturing technology has undergone profound changes. Due to the social demand for diversification of products is more intense, more varieties, small batch production increasing proportion in WEDM by traditional processing equipment has been difficult to adapt to the processing of high efficiency, high quality, diversified requirements, CNC technology should be used
Q:Graphite electrode specifications, graphite electrode manufacturers which good?
Graphite electrode has good electrical and chemical stability. It has high mechanical strength, low impurity content and good vibration resistance at high temperature. It is a good conductor of heat and electricity. Qingdao Chenyang graphite graphite electrode quality is good, they are a direct manufacturer of graphite electrode. Hope to be of some help to you.
Q:Does the silicon carbide heat plant require a fine structure graphite electrode? What kind of graphite products do you need?
Silicon carbide graphite is very famous for its high hardness and wear resistance. It is generally used in high wear resistance machinery industry and high wear resistant sealing industry.
Q:What is the difference between SGL graphite electrode and graphite electrode in general?
Can not say that the more detailed the better, is relative, must be uniform within the range (after all, it is very important to choose the aggregate), such as spectral pure graphite, is not due, he is a lot of technology to producing stains, then burning, and then producing stains, the strength is quite good,
Q:Can Naiduo high temperature graphite
Graphite cut gasket is from pure graphite plate drilling or cutting and it has good corrosion resistance, high / low temperature, compression elasticity and high strength good, complex geometric gasket circular is widely used in all kinds of pipes, valves, pumps, pressure vessels, heat exchanger, and condenser generator, air compressor, exhaust pipe, refrigerator etc..
Q:How to improve the efficiency of graphite electrode milling, please tell me
When the tool is broken, it will not only stop the continuous processing of the steel, but also affect the quality of the product, which will lead to the scrap of the parts and the waste of the material. Considering the foreseeable future, the graphite electrode will occupy a high position, usually used equipment for processing graphite electrode the highest efficiency mold manufacturers will unremittingly, expand and between those determined to use the hard steel processing manufacturer competition gap. The foundation of micro cutting tools, in terms of graphite electrodes, is one of its most magical words: "high speed."". The spindle speed of the high speed machining center is up to 30000~60000r/min, and the feed speed can be increased to shorten the processing period and improve the quality of the surface and edge. The motor needed to drive this type of spindle is relatively small and light, which helps to reduce cutting power and reduce tool breakage. This is critical because many of the electrodes are complex, and their production involves small, easily broken micro tools (see Figure 1).
Q:Why should the carbon brush for the trolley be made of graphite?
What you said is the graphite electrode graphite, there may be a high pure graphite graphite conductive rate so high, strong, high density, the graphite is mostly used in motor vehicles, such as generators, and electric tools.
Q:Is the anode of electrolytic water suitable for ordinary titanium wires?
Graphite firstFirst of all, the titanium electrode is usually not pure titanium, it should be titanium with a metal oxide coating. Secondly, the advantages of the titanium electrode is mainly to save electricity, the corrosion resistance of carbon is much stronger than that of industrial production, if the meaning is relatively large, but it is still in laboratory experiments, electrolysis of water, not what meaning.
Q:In EDM, the electrodes are made of graphite and copper. Please tell us the difference between them
For the mold finishing, most of the time are red copper click, low loss, high precision, of course, higher precision, or requirements of copper tungsten alloy electrodes are also available
Q:How to solve the problem of graphite electrode being crushed during electrolysis
This graphite electrode is so true because it causes gas to expand and disintegrateTantalum electrodes can be solved and not expensive
