Molybdenum wire

specification	Type	Diameter	Mg/200mm	Length of one spool
High strength tensile	Mo-1	0.10mm--0.35mm	16.33mg---200.04mg	Above 1000 meters.
size-confined	Mo-1	0.10mm--0.35mm	16.33mg---200.04mg	Above 1000 meters.
drawn in lower temperature	Mo-1	0.10mm--0.35mm	16.33mg---200.04mg	Above 1000 meters.

Characteristic of our Molybdenum wire:

1. Meeting the standard of GB4183-84. At the same environment and status, the using time could be improved to 100% or 200%.
2. Extend rate less 3%. The molybdenum wire could keep their good status.
3. The molybdenum wires are same size and lubricity on the face.
4. There are all kinds of molybdenum wire in our factory and they are good quality.
5. The molybdenum wires are packed at vacuum environment and could be kept more than 1 year.

Brass wire

Standard: China GB and Japan JIS
Material: CuZn35 or CuZn37
Color: Golden
conductivity: 18-20% (IACS).
Tolerance of the diameter: 0/-0.002mm

Type	Standard Diameter (mm)	Tensile trength (N/mm²)
Hard	0.10,0.15,0.20,0.25,0.30	900～1100
Semi Hard	0.10,0.15,0.20,0.25,0.30	600～900
Soft	0.10,0.15,0.20,0.25,0.30	480～600

Characteristic of our EDM wire
1. All types of EDM wires
The diameters are from 0.10mm to 0.30mm etc. Weights of one spool from 15KG,10KG,5KG,3KG.
2. High tensile strength
We manufacture our EDM wire from powder to wire with fine raw materials of the brass alloy under the circumstance of advanced equipments and continuous process that guarantees the stable of the chemical composition and fine tensile strength of our EDM wire.If the tensile strength is lower, the wires are easy to be broken when the current power is increased. The wires are not easy to be broken during the operation. If the wires are broken, it will waste more time repairing the machine.
3. Good precision performance:
We have advanced inspection instruments and automatic drawing machines, which could control the precision of our EDM wire. The tensile strength could be up to 1000N/ mm2, the tolerance could be within ±0.001mm. Our wires could be widely used in all kinds of slow speed EDM machines in many countries. The surface and tolerance are good enough to have the performance of high operating efficiency.
4. There is no brass powder on the surface of our brass wire that could prolong the life of the tools and develop the efficiency of the operating.
5. The wires are not easy to be twisted during the operation. If the wires are twisted, it will result the broken of the wires and the bad surface of the machine tools.
6. The uprightness is above 98%. If the wires are easy to be curved, it is difficult to insert the wires.

Wire cutting fluid

Introduction:
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 technical leading 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 packingbucket.
