CNC Wire Cut Material Guide

CNC wire cut, also known as wire EDM , is a method where a thin single-strand metal wire is used to cut a workpiece. It’s especially useful for materials that are hard to cut using other methods. Here’s a guide on the Cuttability and Tolerance of different materials when it comes to wire cutting:

Material Cuttability Tolerance Range
Tool Steel Excellent ±0.005 mm
Stainless Steel Very Good ±0.005 mm
Aluminum Good ±0.006 mm
Conductive Plastic Fair ±0.01 mm
Conductive Ceramic Limited ±0.01 mm


Metal wire cutting: Metals often have high melting points, making them a good fit for wire cutting, as the method doesn’t require significant heat.

Best Application: Producing intricate shapes on hardened steels, making tools, dies, and punches.

Plastic wire cutting: Certain plastics can also be wire cut, especially if they are electrically conductive. The finish is usually smooth.

Technology Overview

What is Wire Cut ?

The only difference between a wire cutter and a standard EDM is that a wire cutter uses copper wire electrodes of thickness varying from 0.02 to 0.3 mm. When the material to be cut approaches the copper wire electrode, the electrode’s electrical charge tends to jump over to it, creating the spark needed to cut the material. Here the workpiece should be a conductive metal so that the electrode can produce the spark.

The hardened metal and alloys, which are challenging to cut with other machining operations, are machined using the wire cut method. Because wire cutting entails applying minimal stress and little to no change in mechanical properties, it is also a successful machining technique when consistent mechanical properties are required. In addition, parts with Complex geometries, hard metal with tight tolerance requirement, excellent surface finish, and fine holes are achievable with wire cut CNC machining method.

Working Principle of Wire Cut

A low conductive liquid media (dielectric-fluid) is placed between the wire electrode and the metal to be cut. Next, the electrode wire moves close to the workpiece,

The wire becomes the cathode and the workpiece the anode when the electric supply is turned on. Due to the release of ions from the workpiece and the wire, ions tend to accelerate, increasing their kinetic energy and temperature, which leads the dielectric fluid to conduct. A spark will be produced when there is a potential difference between the electrodes once dielectric fluid starts to conduct electric current. The spark erodes the material from the pre-set position. After that, it moves away along a computer-controlled path.

The movement of the cutting wire is multidimensional, allowing the workpiece to be cut on many faces with a single setup while instructions are being sent through the computer.

The process of Wire Cut

The electrode is accurately positioned by providing coordinate instructions on the CNC machine before processing the wire cut. Since every tool used in CNC wire cutting can detect contact, they all operate using the automatic edge and center locating feature.

The wire does not touch the workpiece during the CNC wire cut process; instead, a spark is produced to carry out the operation. Cutting wire that has been electrically charged will increase the electric field as it approaches the workpiece. When it reaches electrical breakdown, the die-electric material placed between them will spark. The workpiece will then start to degrade as the spark jumps across it. The wire is continuously sent through the operation so its erosion won’t affect the cutting process.

The guide that supports the CNC wire cutting machine can move along three axes and in the x-y plane. The CNC computer controls the workpiece and guides movements.

Technical FAQ’s

What are standard tolerances I can get from Prolean's?

We offer a total machining tolerance of 1/100 to 2/100 mm for wire cut operations. Using better temperature control, we may provide tolerance of as near as 5/1000 mm for sensitive products.

What types of wire cut machines do Prolean's have?

We can create precise structures for you using high-speed KNUTH wire EDM machines, which can work with steel, brass, aluminum, hard alloys, and even steel that has been hardened or tempered. We can handle workpieces up to 800 kg and 1200 mm in diameter.

What is the difference between CNC wire cutting and conventional machining?

CNC wire cutting is a type of EDM that uses a computer to control the wire’s movement, ensuring precision and accuracy. In contrast, conventional machining employs manual methods or traditional cutting tools.

Can you explain the wire cutting process?

The wire cutting process involves a thin metal wire charged with electrical current to erode and cut through a workpiece. The workpiece and wire don’t make direct contact. Instead, they’re separated by a thin gap filled with deionized water, which flushes away eroded particles.

General FAQ’s

Is wire EDM prototyping available?

Yes, wire EDM prototyping is available for clients looking to create a sample or prototype before full-scale production. It allows for intricate designs on even the hardest materials. Please contact us if you need rapid prototyping with wire EDM.

How do I get wire EDM quotes?

To receive wire EDM quotes, please provide us with the details of your project, including the type of material, thickness, and Drawing of your project. You can submit your request through our online form or contact our customer service team.

What types of shapes can be produced by a wire cut approach?

With the help of the CNC wire cut process, nearly all conductive metals and alloys with a thickness of no more than 300mm can be cut accurately. Steel, titanium, aluminum, brass, and even hardened alloys are on the list of materials. Applications include machine parts, brand logos, small prototypes with precise tolerances, stamping dies, minor hole drilling, and blanking punches.

What is the difference between traditional EDM and wire cut approach?

The primary difference between wire cut and EDM is that wire cut uses brass or copper wire as the electrode, whereas wire structure is not used in EDM. Compared to functionality, the wire-cut technique can produce smaller angles and more complicated patterns.

What are the advantages of the wire cut method?

Three primary benefits include the ability to achieve great precision and accuracy. Next, wire Cutting takes less force because there is no direct contact between the tool and the workpiece. Finally, while other machining methods have issues with the hardness and toughness of the work material, this one does not.
