Wire cut EDM coolant BM-4
| BM water base working fluid | Saponification |
Environment | A. compose by water, no oil, no pollution, no pulverization when working, no effect to body B. no oil pollution when working, clean and transparent. use repeatedly, down the cost, can be discharged directly, has been tested by ISO14001 environment requirement, pass European RoHS chemical test SGS-CSTC | It will be olid and back when working, harmful to body. Also it is bad to machine electrical part, and it is forbidden to discharge directly
|
Efficiency | Improve workpiece finish, and efficiency is 20% higher than saponification, especially to big workpiece it is more obvious. Because of better separate feature, the wire is not easily to broken, and the machining precise be better, steady be better | Normal workpiece and efficiency. It is very hard to work when workpiece height more than 500mm. it can case wire broken and shortcircuit often |
Cost performance | One barrel (5L)BM-4 water base working fluid is more cheaper than saponification, can be consumed for 45 days, it is more economic because repeatedly, have better cost performance than saponification | Same 5 L saponification only can be consumed for 30 days, and need to change per 7-9 days |
BM-4
Working fluid (concentrated)
Apply to CNC wire cut EDM machine.
Use method:
- 1. Before first use, please follow the instruction.
- 2. Before use, please thoroughly clean the cooling system with mixed fluid. The cooling system includes tank, pump, working table, wire-winding part and so on. It is better to open and clean the pump. Please don’t rinse with water directly.
- 3. While mixing, dilute in a ratio of 1 part fluid to 20-25 parts water (If the thickness of workpiece is more than 300mm, the dilution ratio is 1:20 ).
- 4. When working 3-4 days or the water levels fall, please add new fluid to the tank. Make sure using the mixed fluid.
- 5. When working a long time, please replace new fluid in time. This can guarantee machining precision.
- 6. In order to achieve ideal effect, please clean the finished workpiece with mixture like BM-11 detergent. If keep the workpiece for a short time, please dry it. For a long time, please use BM-50 rust-proofing agents.
Important:
- 1. Ordinary tap water can be used to mix with the working fluid. Don’t use the well water, hard water, unclean water or other mixture. The purified water is recommended.
- 2. Before completion of processing, please use magnet to hold down the workpiece.
- 3. Don’t let machine stop for a long time avoiding being eroded. If stop for a long time, please clean the machine bed and its cooling system, then dry it for spare.
- 4. If installing filterable water-cycling system or filter in work table and water tank inlet, the working fluid will be much cleaner and the use life will be longer.
Note:
- 1. Store it in cool place and keep away from the children.
- 2. If touch the eyes or mouth, please rinse with water right away.
