Eco Blue Three• A definitive alternative to metallic cutting oil, Eco Blue Three is born as
ecological cutting water that makes a difference in production process.

Applications
Machine Tool for Cutting of Metals and for Use inFactories

Otomo Machine Manufacturing Co., Ltd.

Features• Metal can be cut by water, which realizes simplification of the degreasing cleansing
process.
• Cutting water solves various problems formerly caused by oil cutting, or rust,scattering of mist, foul smell, skin damage, or soil pollution.
• Use of water for cutting can reduce the total cost for the entire plant.

Overview (Technical principles, actions, etc.)
This is alkaline water produced from purified tap water by photo catalysis and the artificial zeolite
catalyst circulation mechanism in order to improve the workplace environmental improvement oil.
Eco Blue Three is produced by adding highly concentrated hydrogen ions (about 9 ± 0.5 in pH) totap water for about 2.5 hours (50 L per production). Production time increases as the production
process is repeated twice or three times, with the maximum production of eco water per a whole
set of process being 600 to 800 L. Since only about 1.5% rust preventive is added to the produced
water, there occur no oiliness in water even though it is scattered around. When it is taken in by
the human, it has almost no negative impact. To use Eco Blue Three requires no change of theexisting plant. No change in durability will also result from its use. Eco Blue Three is currently
being put to practical use by many users, and we hope to increase its sale.

Effects
Comparison between conventional cutting oil and our oil-free cutting water (Eco Blue Three)
Conventional cutting water (water-soluble oil)Oil-free cutting water (Eco Blue Three)(1) Full cleaning of processed items is necessary.

(1) Item is cut while being cleaned. Therefore, onlyrinsing is necessary after cutting.

(2) Fire extinguishing equipment is necessary
because of the use of oil.

(2) No fire extinguishing equipment is necessary as
the water contains no oil.

(3) Cutting heat may negatively affect theprocessing machine or work precision.

(3) Since the water contains no oil, it provides goodcooling performance.

(4) Oil smoke or oil mist may have negative impact
on the human body.

(4) No negative impact will occur to the human even
if the water is inhaled.

(5) Foul smell around the factory, sticky floor, risk ofslipping.

(5) Safety is ensured as the water has no odor, itevaporates, and it thus causes no slipping.

(6) The total running cost for the production process
is high.

(6) Some 50% total running cost reduction may beachieved by elimination of the oil problem. Excellent
in environmental protection and energy saving
performance.
