ABS


ABS (Acrylonitrile Butadiene Styrene) is an affordable thermoplastic that has become popular for pre-injection molding prototypes. It is a versatile material known for its strength, durability, and resistance to impact and heat. ABS plastic is widely used in the automotive and consumer electronics industries due to its excellent mechanical properties and ease of processing. Additionally, it can be easily modified with other additives to enhance specific properties such as flame retardancy or UV resistance.

About Electrical Discharge Machining

JingYu offers two types of Electrical Discharge Machining (EDM) processes, which are useful for cutting deep pockets and complex features such as gears and holes with a keyway. EDM is also a non-contact machining method and does not exert cutting forces on the part, therefore it works particularly well for delicate structures.

CNC Machining FAQs

Technical FAQs
What kinds of gears can JingYumanufacture with electrical discharge machining?

There are two types of EDM, each with their own gear manufacturing capabilities. Wire EDM can be used to manufacture both internal and external gears, as long as there is a through hole or area for the wire to pass through. Sinker EDM can also be used to machine internal and external gears, as well as gears with more complex geometry, like helical gears.


What materials can JingYu cut with EDM?

Both wire and sinker EDM can only be used on materials that can conduct electricity, because the electrode needs to be able to wear away the material. This limits the EDM process to metals.


General FAQs
What is electrical discharge machining?

Electrical Discharge Machining, also known as EDM, is a non-contact machining procedure used to make parts where material is removed from a workpiece using electrical spark erosion. EDM is good for more delicate projects as it does not exert cutting forces on the workpiece.


What are the types of electrical discharge machining?

There are two main types of Electrical Discharge Machining (EDM) processes - wire EDM and sinker EDM, which are useful for cutting deep pockets and complex features such as gears and holes with a keyway.


What types of shapes can a wire EDM machine produce?

Wire EDM machines can handle jobs that can be too intricate or delicate for other methods of machining, such as internal fillets, corners, or other very small and complex parts.


What happens in the EDM process?

The EDM process consists of a metal part being submerged in dielectric fluid, where an electrically charged wire is then fed through the submerged metal component to make the precise cuts.
