Finishing Options
As the machined or deburring
The machined or deburring finish is the standard finish where unwanted attach chips are removed with deburring tools, and sharp edges are chamfered to smooth the surface (3.2 μm).
Bead Blasted
Bead blasting produces a matte texture, removing all the marks of machining tools. It applies to ABS, Aluminum, Brass, Stainless Steel, and Steel parts.
Anodizing
Anodizing involves adding an aluminum oxide coating to aluminum and its alloys. The layers, which come in various colors, increase strength and shield the surface from corrosion.
Powder coating
Powder coating is the electrostatically applying of dry powder to the surface. It produces a thin layer providing excellent resistance to wear, corrosion, and abrasion.
Polishing
Physical rubbing of a metal surface to create a shiny surface is called a polishing surface finish. It increases the reflectivity and does not affect the dimensional stability of parts.
Brushing
Brushing is achieved by applying an abrasive brush to the metal surface, which produces a unidirectional satin finish. And it is not recommended for highly corrosive materials.
Smooth machining
Smooth machining is done by controlling the machining process, such as feed rate & cutting speed. It minimizes the tool marks and risk of corrosion.
Black-Oxide
Black oxide finish reduces surface reflectivity and offers mild corrosion protection. It involves adding a thin layer of magnetite to the surface.
Electro-less Nickel Plating
A thin layer of Nickel is created on the surface from a nickel-containing solution without electrolysis. Electro-less nickel plating provides a shiny appearance, excellent hardness, abrasive, wear, and corrosion-resistance to the substrate material.
Alodine
Provides excellent corrosion resistance property to the aluminum parts with greenish-gold color. It is the low-cost and quick surface finishing approach.
Electroplating
Electroplating increases the hardness of the steel &aluminum parts. It offers excellent corrosion, wears, and abrasion resistance.
Nickel plating
Make the parts super resistive to corrosion. It enhances mechanical strength, hardness, wear resistance, lubricity, and ductility. Nickel plating is applicable in different materials, including Steel, aluminum, copper, and brass.
Passivation
Enhance the appearance and functionality of the parts. After Passivation, parts of Steel and its alloys become super resistive from corrosion.
Yellow Chromate conversion coating
A shiny appearance with goldish color provides excellent corrosion resistance. It is applied on the surface of aluminum, magnesium, and their alloys. A layer of chromate also enhances the conductivity of parts
PTFE (Teflon) Coating
The Teflon layer on the parts offers excellent corrosion resistance, water resistance, and non-stickiness with a non-reactive surface.
Fine machining
The higher-precision machines produce delicate machining surfaces by utilizing sharper tools and regulating feed rate and cutting speed. Surface roughness up to Ra 0.8 μm can be maintained with smooth machining.
Laser Cladding
Provides excellent corrosion, wear, and abrasion resistance. Laser Cladding is also effective for treating minor surface imperfections such as cavities, tiny cracks, and rust damage.
Sanding
Provides a random, non-linear texture with a shiny, high gloss finish. However, it might be unable to create sharp corners and pockets

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.

General FAQ’s
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.
