Metalworking fluid Foam Terminator! A secret weapon of precision manufacture
In precision grinding and cutting, the foam of metal working fluid can lead to uneven cooling, shortened tool life, and even affect the surface finish of the workpiece. Traditional defoamer is easy to delaminate with emulsion, resulting in equipment clogging. Special defoamer for metal processing, through the unique "micro-emulsion nano-dispersion technology", to achieve perfect compatibility with fully synthetic/semi-synthetic liquid, escort for high-end manufacturing industry.
First, the devastating impact of foam on processing accuracy
Loss of accuracy: the foam makes the coolant unable to cover the tool evenly, and the workpiece roughness rises by 2 levels;
Tool loss: local overheating leads to a 30% reduction in carbide tool life;
The filter system is paralyzed: foam blocks the filter element and the replacement frequency is increased by 3 times.
Two, four dimensional performance breakthrough
Particle size ≤100nm: stably suspended in the processing liquid to avoid deposition stratification;
Hard water resistance > 500ppm: calcium and magnesium ions do not affect the defoaming efficiency;
Resistance to biodegradation: maintain activity for 6 months in the bacteria-containing solution;
Zero silicon residue: Avoid surface contamination of precision components.
Third, automobile crankshaft production line demonstration
Original pain point: a German car company crankshaft grinding line due to foam caused the batch of workpiece Ra value exceeded (> 0.4μm).
Modification scheme: Add defoamer (concentration 0.008%) in the central liquid supply system.
Comparative data:
Indicators before use after use
The workpiece Ra value is 0.45±0.1μm 0.32±0.05μm
Grinding wheel dressing interval every 200 pieces every 300 pieces
Filter replacement cycle twice a week, once every 2 weeks
Monthly scrap rate 3.2% 0.8%
