Machining fluid shearing technology
Just installing SIO in a machine tool (grinding machine, machining center) will greatly improve the performance of machining fluid, demonstrate orders of magnitude of cooling effect, and incomparable cleaning effect.
This will revamp QCD (quality, cost, delivery time), which is an important task at the processing site. It also contributes to the processing of difficult-to-cut materials.
SIO technology
-
SIO breaks the hydrogen bond of water and reduces the molecular aggregate.
The surface tension and viscosity of water are lowered, the degree of penetration into a narrow part is raised, the water becomes smooth and lubricity also increases. This enhances the cooling effect, improving processing efficiency and processing quality.
-
The superior stirring ability of SIO improves the wettability of machining fluid.
The superior stirring ability of SIO improves the wettability of machining fluid and can use machining fluid without waste and improves the cooling function, cleaning function and lubrication function.
-
A special internal structure generates micro-fine bubbles.
Shock wave caused by explosion of micro-fine bubble removes sludge and chips adhering to grinding stone, drill, workpiece, and it improves processing efficiency and improves processing quality.

SIO cross section
Benefits of SIO
[Problem]
Grinding is a neck process and processing speed needs to be increased
[Effect]
Increase the amount of cut, enabling machining with increased feed rate, improve efficiency, eliminate bottleneck
[Problem]
Improve the roughness of the finished surface, realize mirror finish
[Effect]
Since the sharpness of the grinding stone improves, it is possible to decrease the grain size and to increase the depth of cut and process it. As a result, the surface roughness is as fine as the particle size
[Problem]
The life of the grinding wheel, the dress cycle is short and the operation efficiency of the machine is bad
[Effect]
Improve the clogging of grinding wheel, extension of grinding wheel life and dressing cycle, improve machine operation rate
[Problem]
Struggling with difficult-to-cut materials (ceramic, stainless steel, carbon, chrome plating etc.) (time, yield, completeness)
[Effect]
Increase speed, grinding wheel life, dress cycle, improve grinding rate drastically than conventional machining
