What Is Stainless Steel CNC Service
Stainless steel CNC machining is an accurate and efficient machining process that uses CNC machines to shape, fabricate and cut stainless steel parts. Numerous industries use stainless steel because it is durable and resistant to corrosion. However, CNC machining is a flexible and cutting-edge technique for producing intricate stainless steel machined parts with great precision. The stainless steel CNC machining process starts with producing a compute-aided or digital design model of the desired parts. CAM (Computer-Aided Manufacturing) software then converts this design into code machines can read.
Advantages of Stainless Steel CNC Service
Appearance
The stainless steel color is silver-white and does not tarnish or corrode with time. Chromium in large amounts is what gives it its look. Apart from strength, stainless steel also has other characteristics. Because of its lovely appearance, this metal is used in many different items. CNC-machined stainless steel parts have a clear, contemporary look without losing functionality.
High Tensile Strength
Stainless steel has a greater tensile strength than mild steel, brass, and aluminum alloys. The tension required to stretch a material to its breaking point is known as tensile strength. This is an essential quality for many products throughout their useful lives, especially for parts that would undergo a lot of bending and rolling.
Corrosion Resistance
Stainless steel alloy has good corrosion resistance and can resist rust and water stains. Stainless steel is perfect for indoor and outdoor applications because of its corrosion resistance. Due to the presence of chromium in the metal, which creates a thin layer to protect the steel when it comes into contact with oxygen, stainless steel possesses this feature.
Cryogenic Resistance
Some stainless steel grades remain stable at a range of temperatures. For instance, austenitic stainless steel alloy displays excellent toughness and enhanced tensile strength at temperatures below zero. Nevertheless, it's crucial to remember that not all stainless steel grades have this characteristic.
Different Types Of Stainless Steel CNC Service
This CNC machining material comes in various types. Each of them has unique qualities that suit different requirements. These are some of the common types of stainless steel for CNC machining:
Austenitic Stainless Steel
The most popular form of stainless steel is austenitic stainless steel. and are highly suitable for CNC machining due to their excellent formability, weldability, and corrosion resistance. This category's two most common grades are 304 and 316 stainless steel.
Martensitic Stainless Steel
Martensitic stainless steel was named after Adolf Martens. These steels are renowned for their extraordinarily high toughness. These steels must undergo aging and heat treatments for high hardness and tempering. It can have a low or high carbon quality. Examples of martensitic stainless steels are X12Cr13, X20Cr30, X50CrMoV15, and X17CrNi16-2.
Ferritic Stainless Steel
Ferritic stainless steel was discovered in 1912. However, it didn't become known and considered for various applications until about 1980. They belong to the family of AISI 400. Examples of ferritic stainless steel are Type 405, Type 409L, Type 410L, Type 430, Type 439, and Type 447.
Duplex Stainless Steel
The structural design of duplex steel consists of two parts. It combines ferritic and austenitic stainless steel resulting in duplex alloys. These two essential structural components are enhanced by duplex steel alloy. This stainless steel is available in three grades: normal, super duplex, and lean duplex alloys. Examples of duplex stainless steel are X2CrNiN22-2, X2CrCuNiN23-2-2, X2CrNiMoSi18-5-3, X2CrMnNiMoN21-5-3, X2CrNiMoCuN25-6-3, and X2CrNiCuN23-4.
Precipitation-Hardening Stainless Steel
Precipitation Hardening stainless steels can also be called PH stainless steel alloys. These alloys contain trace amounts of other substances, such as titanium, copper, phosphorus, or aluminum. These steels go through an age-hardening process after alloy production. Stainless steels that precipitation harden can yield strengths 3–4 times greater than those of austenitic stainless steels. An example of PH stainless steel alloy is 17-4 PH Steel.
Applications of Stainless Steel CNC Service
The application of stainless steel CNC machining is observed in multiple applications and some of these are as follows:
Aerospace
In the aerospace industry, the airframe, landing gear, and jet engine components are manufactured using stainless steel components which are processed through CNC machining.
Automotive
CNC-machined parts of stainless steel are used in automobiles, parts like connecting rods and engine components are manufactured using the stainless steel material.
Construction
Stainless steel is known for its resistance and strength which makes it suitable for the structure of bridges and it is subjected to CNC machining.
Chemical
The chemical industry uses stainless steel parts made using the CNC machining process due to its durable and corrosion-resistant nature.
Kitchen Utensils
Various kitchen utensils like pans, pots, cookers, and cutlery are made using CNC machining stainless steel.
A cutting force and temperature that are both high
The cutting force is strong due to the material's high strength, high tangential stress, and high plastic deformation during cutting. Additionally, the material has a very low thermal conductivity, which raises the cutting temperature and frequently concentrates the high temperature in a long, narrow region close to the cutting edge, hastening the wear on the cutting tool.
Severe work hardening
The austenitic structure of austenitic stainless steel and some high-temperature alloy stainless steels contributes to its strong tendency to work harden during cutting, which is often several times that of regular carbon steel. Cutting at the work-hardening region shortens the tool's lifespan.
Easy to stick to the knife
Strong chips and a high cutting temperature during processing are properties shared by austenitic and martensitic stainless steel. The surface roughness of the machined items will be impacted by sticking phenomena like bonding and welding that happen when the tough chips pass past the rake face.
Quicker tool wear
The materials indicated above typically contain components that have high melting points, high plasticities, and high cutting temperatures, all of which cause tools to wear out more quickly and require more frequent sharpening and replacement, which reduces production efficiency and raises tool costs.
We discuss the processing technology of stainless steel CNC service, overcome its processing difficulties, greatly improve the tool life of stainless steel when drilling, reaming and boring, reduce the number of times of sharpening and changing tools in operation, and improve production efficiency and hole processing quality, reduce the labor intensity of workers and production costs, and can achieve satisfactory results.
Finishes and Post-Processing Options of Stainless Steel CNC Service
As-Machined
As-machined is the most basic and economical CNC finish, often used in applications where the surface won't be visible, and appearance isn't a priority.
Bead-Blasted
Bead-blasted CNC machining produces a matte finish with texture and evenness. The finish is achieved by blasting stainless steel with an abrasive media such as glass beads, aluminum oxide, or silicon carbide. Bead blasting creates a consistent look in end products with multiple parts machined from the same material.
Anodized
Anodizing creates a protective oxidation layer on the surface of a part, usually through electrochemical processes. Anodized CNC machined parts can be dyed in different colors. This finish is often used for stainless steel parts that will be exposed to an outdoor environment, as the oxidation layer helps protect them from rust and corrosion.
Powder-Coated
Powder coating is a type of finishing applied to machined parts, where a polymer-based powder coating is melted and cured onto the surface. It's a durable and cost-effective finish that can be used to add color and texture, as well as provide additional corrosion protection.
Generally, there are many factors you should consider before choosing stainless steel for any machining process. They include
Cost
Stainless steel material price varies depending on the grade.
Grade Availability
Some stainless steel grades are made on order and not available on demand. Ensuring your desired stainless steel grade is available is important especially where you have time concerns.
Heat Treatment
Impacts on the hardness of your stainless steel and thus overall mechanical properties. However, austenitic steel grades are not subject to heat treatment.
Magnetism
Some applications may require magnetic properties which you will find absent in austenitic stainless steel grades.
Strength
The tensile strength vary depending on individual elements in the stainless steel material.
