DIC-206 is energy-saving and emission-reduction type WEDM fluid. The formula of DIC-206 Water-Soluble WEDM Concentrate is completely made up of water-soluble materials. Electrical corrosion products can disperse in the water solution quickly, and could be separated after sedimentation and filtration. Rat oral acute toxicity tests result is "non-observed toxicity". No black sludge will emerge on the cutting surface of workpiece. It is the best working fluid for [Medium speed WEDM" (NC reciprocating travelling wire electrical-discharge machines with repeated cut function); with outstanding features of health and safety and so on. All of the RoHS Directive items testing results are [N/D" (not detected). Working Concentration: Concentrate has to be diluted by pure water (DI water). Suitable working concentration is recommended in the operating manual. It shall be check by handhold refractometer WY-20R. Supplementing water is necessary every shift in daily work. After that, checking and judging if supplementing DIC-206 concentrate is necessary must be done. Since the boiling points of effective components in working fluid are higher than water, the concentration will generally increase if water is not supplemented. Application: 1. A suitable filter (we can offer) must be installed on the exit of circulating pump to remove larger particles of electrical corrosion products. Then, the effect of cutting process could be ensured, and the using term of working fluid could be long. 2. DIC-206 cannot be blended with other WEDM fluids for use. 3. When using DIC-206 instead of emulsion coolant, the following steps shall be done: A. The whole fluid feeding and circulating system, after draining off the previous emulsion, shall be cleaned thoroughly with suitable cleaning agent. B. The machining parameters shall be regulated: increasing the electric current and the feed rate properly. 4. If there are some oxidation products leaving on the machined surface of workpieces after operating with DIC-206, use alcohol to erase. Or, grit blasting can get better effect. 5. Rust protection of workpieces and other ferrous metal parts must be done every week, using 16.7% working fluid coating on the surfaces to be protected with brush or other adequate tools. 6. Electrical corrosion products that leave on the bridge board, bracket and operating platform shall be cleaned up often (about one or two times one week). Note: 1. We highly recommend you to use DI water! 2. It is possible to appear electrochemical etching occurring on the aluminum wire reservoir if the surfaces of aluminum wire reservoir have not been hardened. Storage: It shall be sealed and stored indoor in the temperature 5~50℃. If you can store appropriately, no shelf-life will be required. Packing: Net weight 10kg (plastic bucket). The packing bucket of DIC-206 is our design patent. Without permission of our company, nobody can use this packing bucket.

CNC wire Cut EDM machine cutting sample In the thread processing because of no residual stress, high processing efficiency and other advantages are widely used in mold industry and aerospace field. The workpiece in the thread cutting process includes the steps such as the ladder hole, the wedge table, the circle and the ellipse. The thickness of the workpiece will change continuously or abruptly along with the processing. In fact, without changing the processing parameters of the case, with the workpiece thickness decreases, the servo processing speed will gradually become faster, resulting in discharge concentration, and prone to broken wire phenomenon; the other hand, the workpiece thickness increases, the servo processing speed will Gradually slow down, resulting in reduced processing efficiency. Therefore, when the workpiece thickness changes during processing, how to make the machine servo feed speed with the workpiece thickness changes in a desired range, is to ensure that the wire cutting processing accuracy and processing efficiency of the important prerequisite, and online identification of the workpiece Thickness is the problem. In recent years, scholars have done a lot of research on the identification of the thickness of wire cutting workpiece. For example, the ability of the pulsating power source, the use of erosion of the material volume and discharge energy ratio of the specific discharge energy concept, the establishment of a workpiece thickness, processing speed and discharge frequency between the data model is suitable for predicting the thickness of the workpiece changes little Wire cutting processing. The feed vector, the feed rate and the pulse interval are chosen as the input, and the support vector regression model of workpiece thickness identification is established to predict the workpiece thickness more accurately. At present, the research on the thickness of the wire cutting thickness is mainly in the one-way wire cutting machine (walking machine), and the workpiece thickness identification is mainly based on the use of energy pulse power in the wire cutting process in the discharge frequency, pulse interval , Feed rate and other factors to predict the model to achieve the workpiece thickness prediction. But these models are based on the establishment of the line cutting gap in the case of the same, and tie the actual processing process, the different processing parameters generated by the line cutting width is changing. At the same time, the type of pulsed power supply is not only a kind of energy pulse power supply, which has caused the limitations of the current technology. Above for the "walking thread cutting can achieve automatic identification of workpiece thickness," the introduction, but so far, can only be achieved in the walking machine. Suzhou Hanqi is a professional manufacturer of wire machine tools, technical cooperation with the Swiss company, machine tool accuracy can guarantee 10 years!

Most customers will be processed by a sample to determine the good or bad, in doing so there are many problems can not leak out, here to cite a few cases for your reference. Case 1) One customer has to purchase more than one threading EDM machine, because this customer has several step-and-drive before the threading machine, the use of one year after the processing index has been lost, the basic use of these machines Fast wire, so the customer is very cautious, with industry experts on a number of silk machine in the inspection, the choice of Suzhou Han Qi in the wire, very satisfied with the use of customers, and then decided to purchase one. Case 2) A customer to purchase wire walking machine, customers for high-precision gear processing, gear precision control in the class, and long-term maintenance. Customers in more than take the silk factory site visits, and finally select the Suzhou take the wire machine. After more than a year of long-term use, machine stable and reliable. Customers are buying Hatch 10 servo-threading machine. Case 3) A customer uses old type structure stepper drive mode of machine parts for processing, but the high-precision parts are out with slow wire processing. Since the purchase of the HANQI full servo in the wire, the outgoing wire processing parts are 90% of the wire used in the process of processing Hanche. Processing results to meet the requirements of long-term stability for customers to save the original. Case 4) One customer originally purchased multiple "C-type" step-and-drive (ie, swing-type) middle threading machines for automotive stamping die processing, which not only requires local processing but also multiple jumps Step processing, these machine jump positioning accuracy are greater than 0.02MM, unable to meet customer requirements, the use of wire walking machine processing costs too much. Later, through the introduction of customers to purchase the full servo servo wire walking machine, processing positioning accuracy are controlled within 0.01MM and so on Through the above several cases I believe we have to take the wire EDM machine with a new understanding of the following from a few aspects of in-depth understanding: 1 fuselage structure: There are two fuselage structure on the market at present, one is "British fork" machine tool structure, the other is "C type" machine tool structure, "C" machine structure is divided into: As the "font" and the fuselage base for the "T-shaped" structure of the two. From the stability of the long-term use of the fuselage, "C" structure than the "British fork" to be stable, C-type T-shaped structure (walking wire body structure) and more than C-shaped structure more stable . 2 Drive: Currently on the market in the wire-cutting machine tool has two drive methods, one is open-loop stepping drive, this drive from China's first research and development of fast wire machine so far nearly half a century has been in Using the drive method, it is widely used in precision fast-running wire machine. It can not achieve high-precision machine tool control. Another is the most widely used high-end CNC machine tools AC servo drive, it has a strong driving ability, high positioning accuracy and many other features, and through the computer for pitch compensation and backlash compensation, μ-class processing accuracy can be obtained And positioning accuracy, it is widely used in high-precision wire walking machine tools, machining centers and other CNC machine tools. 3 wire running way: the stability of the structure of the transport wire is essential, even if the precision machine do no matter how good, not a long-term stability of the wire transport institutions, everything will be out of the question. Molybdenum wire in the high-speed operation on the guide wheel will produce per minute 5000r-7000r high speed. Using the traditional fast-moving silk wire structure, to far can not meet the long-term use of silk threading machine molybdenum wire stability. 4 Water Filtration: The thread cutting machine must go through a good water filtration system, the impurities in the water fully filtered, because the processing power is very weak when the knife repair, water impurities brought about by the secondary discharge will make the entire processing loss Exhausted. 5 power control: power control part of the machine is the most critical part of its high reliability and long-term use is more important. Therefore, by simply processing a sample to determine the good or bad WEDM is wrong. For example, a stepper drive and a servo-driven machine tool to process a simple parts, the processing effect is not much difference, over time, the shortcomings of stepper drive will leak out, processing complex parts and skip processing Precision becomes worse and worse. Suzhou Hanci has developed a water-based cutting fluid, the use of water-based cutting fluid better!

1. Low Cutting Speed/Low processing efficiency 1) the initial discharge of low processing efficiency ----- electrode size scaling amount (spark-bit) to a large, automatic programming can choose a larger number of current conditions. To the extent possible pre cavity milling. 2) low discharge machining stage efficiency program in the middle of each segment condition ----- margin between too much can also be reduced allowance between two segments. 3) low application efficiency ----- final paragraphs EDM machining using the timer function to effectively control the finishing time (need to set the processing time). 4) the area is too small ----- system input area limitation threshold, even if the amount of scaling electrode size is bigger, because the area is too small, it does not produce large discharge conditions. Such cases can be appropriately increase the area of human values entered. 5) the incorrect application type ----- choose such a large cavity is actually processed and the choice of the "standard" type of application. All application types "microfabrication" the least efficient. 6) processing priority ----- Choose low loss priority is low efficiency, choose a high priority is speed and efficiency, the loss is too large. 7) discharge, carrying the knife combination unreasonable ----- according to the processing status, carrying knives to adjust the height, the discharge time match. 8) ----- optimization parameters decrease pulse interval P, to increase the servo reference COMP. 9) the use of improved technology ----- graphite electrodes, greatly enhance the overall productivity 2. Big electrode wear 1) ----- improper use parameters should be used as a low loss priority processing parameters. Small electrodes can choose the type of micro-machining applications. 2) discharge condition number is too small electrode tip ----- For, you can not use a large current process. 3) discharge energy is too small, resulting in inefficient processing time of discharge electrodes and electrode loss ----- if accompanied by a large loss when the processing speed is too slow, increase processing efficiency. 4) the electrode material is not good ----- use high purity copper, or even lower loss Luoyang Copper is a copper tungsten alloy as the electrode material. 5) increasing the pulse width is too small ----- condition number of the pulse width T, can significantly reduce electrode wear. 6) ----- low-loss pulse waveform, a tapered discharge waveform pattern (Mode10) 3. points in the inaccurate position deviation 1) using conventional methods, "the electrodes touch points in the workpiece", because points belonging to surface contact between the electrode and the presence of a number of factors will affect the points in the workpiece accuracy ----- recommended "base ball-point divide in "positioning method. Work bench fixed a benchmark ball as a reference, prior to processing in the spindle head clamping a benchmark ball points on the workpiece, and then on the workbench reference points in the ball, so you get a distance relationship, after all the reference electrode are points in the ball. 2) the electrode and the workpiece datum accuracy, ensure the accuracy of debris ---- electrode and the workpiece datum, and wipe clean. 3) perception of speed is not too fast (Set F: 75mm / min) 4) Use precise clamping and positioning system. 4.The machined surface roughnesss 1) electrode material is not good, there are impurities ----- high purity copper or copper Luo. 2) translational inappropriate choice ----- Use DOWN / ORB translational, and finishing process using a timed section. 3) improper spark oil, spark oil viscosity big spark ----- finishing oil suitable replacement. ----- Appropriate parameters need to be optimized to reduce the discharge time TEROS, increasing the pulse interval P, reduce the servo reference COMP. 4) red liquid mode uneven ----- finishing punch was not additional local. 5) matte surface treatment ----- difficulty factor, and recommend process to VDI14, more sophisticated processing surface of its conditions are demanding. 6) surface effects ----- priority standard of priority is generally better than a low loss priority. 5. The mirror effect is not good 1) Some of the workpiece material can not achieve mirror finish effect, such as SKD11, Cr12MoV, DC53 (most metal stamping die steel) ----- recommend using a mirror finish steel, such as SKD61, S136,718HH, NAK80 etc., or correct understanding deviation . 2) processing area is too large, reach a uniform mirror effect ----- area larger than 25 square centimeters should use the mixed powder processing. 3) translation inappropriate choice ----- Use DOWN / ORB translational, finishing with a timed processing function. 4) processing area entered incorrect ----- enter the exact processing area, so that the system automatically set the timer. 5) ----- mirror finishing segment conditions according to the processing status, carrying knives to adjust the height, the discharge time, carrying the knife to match the speed, do not use the red liquid, the liquid flow to be small. 6) the beginning of the process, the discharge is unstable, often carrying knives The system automatically detects, the impact of adaptive ----- shutdown condition numbers of some automatic protection function (ACC2 / ACC4), reduced sensitivity MS, or the discharge time and carrying knives height control is set in accordance with User settings (User / Fix), so lift the knife presented as a regular, controlled state. (Not recommended, often this instability is having a protective effect) 7) ----- optimize processing parameters to optimize the discharge time, carrying knives height, carrying knives rate, pulse gap servo reference. 6. Processing size failed 1) small size after processing ----- Typically, the size processed using an automatic programming will Shaopian small, which is more secure. 2) Electrode size tolerance ----- check the electrode size, which is the premise. 3) ----- high dimensional accuracy according to the machining conditions, pre-processing, the size of the measured and processed electrode size, adjust translational radius. 7. how to process multiple workpieces A plurality of processing a plurality of workpieces How to use ----- workpiece relative parts function, each piece is set to a relative zero, each piece of the current machine coordinate value memory, the program can take any of these relative zero transfer In order to achieve continuous processing a plurality of workpieces, these artifacts should be set up in the same tray (Mag Pos set to the same value). 8. What are the main points of carbide EDM 1) When the automatic programming to choose carbide processing parameters. 2) If there are higher requirements for electrode wear, rough machining of positive polarity may be used to reduce the electrode loss (the default parameters of the machine are negative, in fact, using the negative impact of thermal processing parameters thin, die life the best, but the loss is large, a plurality of electrodes need to be replaced.) 3) the use of a copper tungsten electrode material, can significantly reduce electrode wear, reduce the number of electrodes.
