Water-soluble metalworking oil base"UTILIOL"

Water soluble cutting oil base with both lubricity and low foaming

What's great about Sanyo Chemical's water-soluble cutting oil base
"UTILIOL". 

1

Water-soluble polyether with excellent galling resistance

Water-soluble metalworking oils are nonflammable, present a low risk of fire, have excellent cooling properties, and contribute to an improved working environment and reduced environmental impact.
"
UTILIOL GA-15P" is a water-soluble polyether with excellent galling resistance, suitable as a base for water-soluble metalworking oils. 

2

Combination of lubricity and low foaming 

Compared to our general-purpose polyether base, "UTILIOL GA-15P" has significantly improved lubricity while maintaining the features of water-soluble metalworking oils. The combination of lubricity and low foaming, which had been an issue with water-soluble processing oils, provides benefits such as reduced environmental impact, improved working environment, and improved cooling efficiency. 

3

Capable of machining difficult-to-machine materials such as highly ductile aluminum 

"UTILIOL GA-15P" has excellent lubricity, making it applicable for machining difficult-to-machine materials such as aluminum, which is highly ductile. 

4

High transparency of processing solution diluted with water

"UTILIOL GA-15P" does not impair visibility due to the high transparency of the processing solution diluted with water. 

5

High handling performance 

"UTILIOL GA-15P" is a water-soluble polyether base agent with low viscosity, high cloud point, and is non-applicable to hazardous materials under the Fire Service Law, making it easy to store and handle. 

Why is low foaming important in water soluble processing oils? 

Conventional water-soluble machining oils often have insufficient lubricity, while foaming is a problem when lubricity is improved. Foaming during machining leads to concerns about overflow, insufficient cooling, reduced workability due to difficulty in seeing the machining point, poor machining, and increased use of machining oil. 

⇒"UTILIOL GA-15P", which has both lubricity and low foaming, can be used in applications where water-soluble processing oil could not be used due to the above problems. 

Intended use

Machine tool lubricants are used in a wide variety of metalworking processes such as cutting, rolling, drawing, pressing, and forging, and their basic functions are lubrication and cooling. 

 The lubricant reduces friction by entering the gap between the tool and the workpiece or chips, and the cooling effect of the lubricant suppresses heat generated by friction, thereby reducing tool wear and deformation, preventing burning and extending tool life, as well as improving machining accuracy.

Lubricity of "UTILIOL"

Lubricity Evaluation 1:  Galling Resistance Load

Fig. Comparison of galling resistance load (SRV method)

(1) High anti-galling load 
"UTILIOL GA-15P" exhibits higher galling resistance load compared to our conventional polyether base. 

(2) Improved galling load resistance due to increased concentration 
"UTILIOL GA-15P" can improve galling load resistance by increasing its concentration. 

<Test conditions (SRV method) >
Lubricity (galling load resistance) was evaluated using an oscillating friction and wear test (SRV tester).
