Metalworking fluid testing has not achieved the degree of standardization or definition of performance requirements found
in other industrial lubricants. Delta Logistics has developed an extensive line of metalworking fluids. These
fall under the general description of:
- Cutting Oils
- Rolling Oils
- Preservative Oils
- Drawing and Forming Oils
Metalworking fluids lubricate BOTH the machine tool and the work piece. They must lubricate,
clean and prevent rust/corrosion at the metal/tool interface.
Metalworking fluids are matched to the application as to OPERATIONAL SEVERITY
and MACHINABILITY OF MATERIAL; sawing is the least severe, whereas tapping/threading are the most severe operation.
Brass is the easiest to machine, whereas titanium alloys are the most difficult.
Fluid types are as follows:
- Oil-Based Fluids: Include staright mineral oils and soluble oils
- Chemical Fluids: Include synthetics and semisynthetics
Soluble Oils [also known as Oil-in-water emulsions ] dominate the market because of low cost and superior cooling,
however, the chemistry must be optimized for these applications. WE at DELTA will help you customize your formulations.
Soluble Oil Fluids form an emulsion when mixed with water. The concentrate consists of a base mineral oil and emulsifiers
and perfomance additives to help produce a stable emulsion. They are used in a diluted form (usual concentration
is 3 to 10%) and provide good lubrication and heat transfer.
Relative Operational Severity:
- Tapping, Threading---most severe
- Gear Cutting
- Boring
- Milling
- Planning
- Truning
- Sawing---least severe
