Small hole EDM Service for Wire EDM Process
Small hole EDM machining was initially used for pre-drilling starter holes for the Wire EDM machines. We still use it for this purpose every day. This process uses a long brass or copper electrode to drill a 0.2-5mm diameter holes for the soft or hard steel and carbide material. The brass is held in the chuck and rotated as flow of water, then wash away the eroded material.
Not only the small hole EDM is used in drilling the holes before Wire EDM process, its used has been widely used in drilling the coolant channel in the cutting tool industry, drilling the holes of the carbide body or steel becomes more recognized now. Mold and parts manufacturing nozzles, oil holes and mold spare parts are just one of this area which benefits from the use of small hole EDM machining.
The Benefits of Small Hole EDM
- Reduce the working time of making a hole of hard materials compared with other manufacturing process.
- Eliminating the possible of size change and deformation caused by heat treating process.
- Cost-effective for producing the holes without tight tolerance.
Related Manufacturing Process
Our wire cutting are highly precise machines with +/-0.002mm tolerance capabilities and no virtually burrs.We can manufacture some of the most complex parts.
The sinker E.D.M is used to create blind shaped forms needing a high accuracy requirement ,the material can be carbide or steel after heat treatment.
