Vacmul EDM 2 and 3
Multipurpose Electro Discharge Machining Fluids
Product Description
Vacmul EDM fluids are multipurpose dielectric fluids for use in all discharge
machines working by penetration especially for roughing, finishing and
superfinishing work. Vacmul EDM is very pure fluid designed for maximum machine
productivity and operator comfort when used in electrical-discharge machining,
also called spark-erosion machining. In this metalworking process metal is
removed from a workpiece by applying a potential difference between the
workpiece and a shaped electrode. Vacmul EDM has the ability to provide uniform
insulation and then to permit controlled electrical discharge at the breakdown
voltage.
Vacmul EDM has the correct balance of viscosity, volatility,
oxidation stability, heat transfer characteristics, low odour and low toxicity.
Vacmul EDM is a highly refined, narrow-cut, low viscosity fluid specially suited
to finishing operations where a high quality finish is required. It functions as
an insulator between tool and workpiece, spark conductor, coolant and as a
flushing oil for chip removal. Vacmul EDM is recommended for roughing operations
where a high metal removal rate is required and for finishing and superfinishing
work.
Features and Benefits
| Features | Advantages and Potential Benefits |
|---|---|
| High flash point | Limits fire risk |
| Excellent filterability through cartridge and earth | Increased production |
| High wetability | Ensures liquid / metal contact and fewer rejects |
| Bright, clean and odourless. | Easy viewing of work piece and fixtures |
| Low skin sensitivity in normal use | Easy handling and improved workshop environment |
| Non fatty compared to more viscous fluids. | Higher metal removal rate and stable electrical discharge |
| Good detergency with respect to small particles. | Provides uniform insulation, higher precision and surface finish |
Applications
Excellent for all electro discharge machines that work by penetration.
Especially suitable for roughing, finishing and superfinishing work.
