Abstract
A cutting method in which a solution is sprayed or jetted to a machining portion when machining by use of a water-insoluble cutting oil, wherein recovered liquid is collected and stored in one recovery tank, and separated into the water-insoluble cutting oil and another solution on the basis of the specific gravity difference, and are re-used. Stable machining is enabled by using the water-insoluble cutting oil, and measures against disaster are fully taken.
Claims3
A reusable water-insoluble cutting oil for machining which is used for a cutting method, comprising the steps of:
- spraying a water solution on a periphery of a machining portion when machining with said water-insoluble cutting oil;
- recovering a liquid including a mixture of said water solution and said water-insoluble cutting oil after use of said liquid for machining;
- directing the liquid into a recovery tank for collection and storage;
- separating said water-insoluble cutting oil from said water solution on the basis of a difference in specific gravity;
- and,
- reusing said water solution and said water-insoluble cutting oil, wherein the reusable water-insoluble cutting oil comprises:
- a principal ingredient which is a mineral oil, or a liquid mixture comprising chlorinated paraffin and a mineral oil or a liquid mixture comprising polysulfide and a mineral oil.
A cutting solution for machining comprising a water-insoluble cutting oil and water-soluble cutting oil which is used for a cutting method, comprising the steps of:
- selectively using said water-insoluble cutting oil or said water-soluble cutting oil;
- recovering a liquid including said water-insoluble cutting oil and said water-soluble cutting oil;
- directing said liquid into a recovery tank for storage;
- separating said liquid into said water-insoluble cutting oil and said water-soluble cutting oil on the basis of a difference in specific gravity;
- and
- reusing said water-insoluble cutting oil and said water-soluble cutting oil, wherein
- the water-insoluble cutting oil has a principal ingredient which is a mineral oil, a liquid mixture comprising chlorinated paraffin and a mineral oil, or a liquid mixture comprising polysulfide and a mineral oil;
- and
- the water-soluble cutting oil has a principal ingredient which is water, a solution of 0.1-2% of triethanolamine, or a solution containing triethanolamine and a medium-chained fatty acid.
A reusable water-soluble cutting oil for machining which is used for a cutting method, comprising the steps of:
