What is Wire EDM?

What is Wire Electrical Discharge Machining?

Wire electrical discharge machining (Wire EDM) utilizes a metallic wire for cutting or shaping workpieces, usually conductive materials, with a thin electrode wire that tracks a specifically programmed path. Usually, the electrode widths vary from .004″ to .012″, nevertheless smaller and larger widths are ready for use.

Throughout the wire cutting process there isn’t any direct contact between the wire and the work piece allowing for machining without causing any deformation in the wires path, or the shape of the material. For accomplishing this, the wire is quickly charged to a required voltage. The wire is also encompassed by deionized water. As the voltage reaches the proper degree, a spark hops the gap and melts a minute part of the work piece. The water cools then removes the minute leftovers from the gap.

The solidity of the work piece material has no damaging impact on the cutting speed. Blanking punches and extrusion dies are frequently machined via wire cutting.

The Way Electrical Discharge Machining Works

The primary EDM process is quite basic. A spark is created between 2 electrodes. The tool electrode is usually known as the electrode, and the work piece electrode as the work piece. The spark is visual evidence of the stream of electricity. This electrical spark produces intense heat with temperatures hitting 8,000 to 12,000 degrees Celsius, melting/vaporizing just about any conductive material. These swift, recurring electrical current discharges happen in a very tiny gap between the 2 electrodes, in which never come in contact with one another. The spark gap is managed by adaptive device controls to guarantee a continual, balanced distance as the electric discharge happens up to millions of times every second.

The spark is very specifically managed and restricted, so it only impacts the face of the material. This process typically does not impact the heat treat underneath the face. Both the tool and workpiece are immersed in dielectric (un-conductive) fluid, usually deionized water.

The spark always happens in the dielectric fluid. The conduction of the deionized water is cautiously overseen, creating a perfect setting for the EDM process. The deionized water additionally provides cooling throughout the machining process, and eradicates the small, eroded metal fragments.

EDM is considered a non-conventional machining technique since it uses electric discharge for removing material from the work piece. This contrasts with conventional machining techniques like grinding or drilling which use mechanical force for removing material.

What Types of Shapes Can A Wire EDM Machine Produce?

Wire EDM machines are a kind of CNC machine that can move along four independent axis to create taper cuts. For instance, a stamping die can be created with 1/4-degree taper or a mold with 1 degree taper in some areas and two degrees in others accurately. Extrusion dies or horns and nozzles can be cut with continually changing tapers. For instance, an intricate shape on top of the work piece can shift to a simple circle at the bottom.

How Does a CNC Lathe Machine Work?

Getting into the inner workings of a CNC lathe uncovers a balance of computerized control and precision engineering. Different from a manual lathe, where the handiwork lies mainly in the hands of its operator, a CNC lathe incorporates computerized technology to improve precision and proficiency. Below is an in-depth look at its process:

Design Phase: To begin with, you, the operator, creates a meticulous design utilizing CAD (Computer-Aided Design) software. This design comprises of all specifications for the desired piece, from shapes to dimensions.

Programming: Your CAD design is then converted into G-code, the programming language that the CNC machine understands. This code gives instructions to the CNC lathe on how to move, shape, and create the piece.

Setup: After that, you configure the CNC lathe. This involves choosing and installing the proper cutting tools and fastening the workpiece onto the machine.

Machining Process: The CNC lathe, activated by the G-code, starts the machining process. The workpiece is spun at high speed while the cutting tool is moved across two or more axis to shape the piece.

Quality Inspected: During the process, the CNC lathe oversees the cutting environments and makes real-time modifications to guarantee precision. The final piece is inspected against the original specifications for preciseness.

What are the differences between horizontal and vertical CNC lathes?

The main differences between horizontal and vertical CNC lathes consists in their position and the applications they’re most appropriate for.

Horizontal CNC Lathes:

  • Positioning: The spindle in this type of lathe is arranged horizontally, with the workpiece mounted vertically to the axis.
  • Processes: Mainly used for longer, cylindrical workpieces.
  • Pros: Easier chip withdrawal because of gravity, typically better for heavier and larger pieces.
  • Limitations: Might not be suitable for parts with intricate geometries.

Vertical CNC Lathes:

What is Machining?

Machining is a manufacturing technique in which the desired shape is produced by removing material from a larger piece. It is used for creating finished products and for raw material processes. These processes are also referred to as subtractive manufacturing processes. Complicated parts usually require the use of several machining processes along with each other.

A lot of machining processes have high command over the material removal for maximum accuracy. Just about all materials, including metals, ceramics, wood, plastics, glass, etc., support machining processes.

How Machining Works?

Machining processes are reliant on a machine tool to work on the raw material to create the wanted shape. Today’s machine tools are mainly automated. They use built-in computing to translate the commands and work on the piece. The technique of commands is subject to the type of technology that the machine uses. A lot of current machining tools are based on Computer Numerical Control (CNC), in which utilizes CAM programming.

Various Phases of Machining Processes

Machining processes go through several phases to complete the pieces production. These various stages are:

Designing Piece: For machine-driven production using a CNC machine, a graphic design of the piece is created. It then gets saved as a Computer Aided Design (CAD) file. Minute adjustments and hand-operated machining may not require designs.

Creating Computer Aided Manufacturing File: The CAM file includes the G-code that the machine can comprehend. The programmer transforms the CAD file into CAM form. An operator then loads the file into the machine. For a machine that doesn’t have CNC, the CAM file is not required.

Machine Configuration: Each machine requires to be configured before initiating the machining process. Configuration includes loading the piece, adjusting the machine settings, and guaranteeing tight connections.

Machining: The machine starts initiating once the configuration is complete. The configuration is done in front of an operator.

Removal: The finished piece is then removed from the machine. It is then sent for secondary assembly or added machining processes as required.
