3 -- 9.
2 when, the bacterium lives hard, answer to add new cutting juice in time so, raise PH cost. Maintain the cleanness of cutting fluid, do not make cutting fluid and corrupt the contamination contact such as oily, food, tobacco. Often use antiseptic. Maintain the cleanness of workshop and machine tool. If equipment did not filter device, answer to cast aside the oil that eliminate float regularly, cleared contamination. Of cutting fluid corrode problem (the scale on the low side that fluid place condenses to occupy in the reason cutting fluid that 1) generation corrodes. Exorbitant or the PH cost of cutting fluid is too low. For example PH ＞ 9.
2 when, have to aluminium corrode action. Answer to choose appropriate PH value according to metallic stuff so. The metallic stuff with Nextpage not similar is contacted. Put work with paper or wood mat. Component is folded put. The amount of the bacterium in cutting fluid exceeds bid. The humidity of working environment is too high. (The method that 2) prevention and cure corrodes makes up cutting fluid with pure water, and the scale of cutting fluid should use the commendation in cutting fluid manual by place the value is used. Below the circumstance of need, want to use antirust liquid. Control bacterial amount, avoid bacterial generation. Check humidity, notice the humidity that controls working environment is inside likely range. Want to avoid cutting fluid to be polluted. Want to avoid not similar material to contact, if aluminium is mixed steel, cast-iron (contain magnesium) wait with copper. When generation foamy problem is using cutting liquid, sometimes cutting fluid surface can produce a large number of foam. (1) generation foamy is main the fluid area of reason cutting fluid is too small. The velocity of flow of cutting fluid is too rapid, bleb spills over without time, accumulate more more, bring about many bubble generation. The right angle in cistern design is too much, or the nozzle angle of cutting fluid is too straight. (2) avoids to produce foamy method to cool in concentration in the system, pipeline classifications series connection, answer from the pipeline pressure with cooling close box a few lower. The fluid face that assures cutting fluid does not want too low, check fluid face height in time, add cutting juice in time. Velocity of flow of control cutting fluid does not want too fast. When designing cistern, should notice cistern right angle is not too much. Should notice when use cutting fluid angle of cutting fluid nozzle does not want too straight. CNC Milling
