The Basics of Custom CNC Machining Parts
CNC machines are very complex and their uses vary depending on the application. CNC machining has become an integral part of many modern manufactured product designs and can be applied in a variety of ways to almost any custom CNC machining part needed for a project.
1.What is CNC machining?
CNC machining is a process used to create high-precision parts. The process typically involves using computer-controlled tools, such as lathes and milling machines, to precisely cut, shape, and drill materials into the desired shape that can be used to produce custom CNC machining parts.
2.What is a CNC machine?
A computer numerically controlled (CNC) machine is a type of automated machine tool. Computers typically control CNC systems and are used in a variety of industries, such as food production and agricultural equipment manufacturing.
A typical CNC machine consists of a computer, control electronics, and motors that work together to perform a variety of tasks. The computer controls the movement of the tool head. The control electronics then move the tool change program (called a “G-code”) that tells the machine what to do.
Each letter and number represents a specific type of movement of the tool head. The motor then moves the tool to perform the operation. CNC machines can perform a variety of functions, including drilling, cutting, or welding. They can do many things with incredible precision and accuracy.
CNC machines are one of the most versatile machines ever invented and can produce almost anything you can think of.
This type of machining uses a computer-controlled machine tool to cut or shape metal, plastic, or other materials. It can also be used to drill holes or polish materials.
3.Types of CNC Machining
The types of CNC machining that can be performed vary, depending on the type of machine used. The two main types of CNC machines are vertical and horizontal CNC machines.
1) Vertical CNC Machines
Vertical CNC machines are the most common type of CNC machines. They are used to cut and shape certain materials, such as metals. These machines are commonly used to cut steel, aluminum, and plastics. Vertical CNC machines are usually 30 inches to 50 inches off the ground.
Typical vertical CNC machines can be quite large because they must have enough space to accommodate the computer system, control electronics, and motors. Vertical CNC machines can cut, drill, and mill a wide range of materials.
2) Horizontal CNC Machines
Horizontal CNC machines are also standard, although they are not as common as vertical machines. However, their cuts are more accurate and precise. They are usually located between 10 inches and 30 inches below the ground. Horizontal CNC machines usually use more powerful motors, allowing for higher speeds than vertical machines.
3) Deep CNC Machines
Deep CNC machines can cut a wide range of materials. These machines usually use a five-axis system to cut a wide range of materials, including plastics and aluminum. The only downside to this type is that it is much more expensive than other types of CNC machines. Deep CNC machines may also be called five-axis or 3+2 machining centers.
Many other types of CNC machining include wire EDM and laser machining. Each machine is designed to handle a variety of projects, but they are also precise in their applications. The processes used by each machine are also different. The most common technique is wire EDM, which is cutting steel or aluminum using wires. Other processes used are laser and water jet machining.
4.Custom CNC Machining Services: Materials
1) Aluminum
This material is used in many industries and is suitable for a wide range of jobs. Aluminum can be machined and welded. It is not suitable for heavy-duty machining, but is more suitable for light-duty machining such as drilling, milling, and tapping. The smooth surface of aluminum provides good grinding and polishing, while the wide range of uses provides a wide variety of applications.
2) Brass
Brass is very similar to aluminum in terms of machinability. Although this material cannot be fully recycled, it can be melted down and reused. Most people think of brass from recycling bins rather than machine shops, but this material is just as valuable. It can be used to make practical parts such as lampshades and sandwich panels. The best thing about brass is that it can be easily polished to look brand new.
Brass is used in many industries and has many properties that allow it to be machined. Brass feels smooth and can take on a lustrous, attractive finish. The properties of brass also make it ideal for various electroplating processes.
3) Steel
Steel is one of the most common materials in a workshop. It is used in a variety of custom CNC machining processes and can be used for many purposes. Steel is durable and easy to machine. Custom CNC machining services can be performed on steel, including drilling, turning, and milling.
The material has a rough, gray surface that is easy to clean up parts and smooth out after machining or grinding. Steel is used in industries ranging from automotive manufacturing to cooking equipment.
4) Stainless Steel
Stainless steel is a non-magnetic alloy that is ideal for custom CNC machining parts due to its corrosion resistance. It has greater strength and durability than aluminum or steel, making it ideal for high-performance parts.
5) Copper
Copper is a soft metal that is ideal for custom CNC machining. Due to its softness, it can be cut with any tool, but it is commonly used in wire-cut and laser CNC machines. It has different grades based on how much impurities and oxides it contains, with the more impurities, the lower the purity.
6) Plastics
Plastic is an affordable and versatile material that can be used for both prototype and production parts. It is easily machined into complex shapes and sizes, making it a great choice for custom CNC machining services.
7) Carbide
Plastic is an affordable and versatile material that can be used for both prototype and production parts. It is easily machined into complex shapes and sizes, making it an excellent choice for custom CNC machining services.
5.Custom CNC Machining Services: Surface Finishing
1) Anodizing
Anodizing is a process that creates a coating on the surface of aluminum to give it a variety of colors. The process can be applied to aluminum or titanium and is used in the automotive industry and military products.
The method uses electrolysis to coat the metal with a layer of anodic oxide. Many different anodizing processes use other dyes, voltage settings, and times. These factors change the depth of the color as well as the thickness of the coating. The color also changes depending on the thickness and finish of the part.
2) Painting
Instead of creating an oxide, the workpiece is coated with paint. The color of the paint used varies by industry and product, but there are a few simple steps you need to follow:
- Clean the surface thoroughly with IPA or degreaser
- Apply primer
- Apply color and clear coat or lacquer depending on the final color tone required
3) Polishing
Polishing is a process performed on parts that have been rough milled. It is used to create a smooth surface, remove waste material, and sometimes remove burrs. The process can be done manually or with a machine that performs abrasive techniques such as polishing to remove scratches and rough surfaces or spark erosion to remove trace materials.
4) Brushing
Brushing is a method of removing dust, grease, and other solids from the surface of a machined part. It is used for intricate areas that other cleaning methods cannot reach. Simple manual brushing can be done by hand or with a spray gun. Many manufacturers use a scrubbing mechanism to remove surface contaminants and severe contaminants that cannot be removed by hand.
5) Plating
Plating can be used to add an extra layer of protection and durability to a part. This method covers the surface of the part with a thin film of metal, such as zinc or copper, which provides additional strength and durability.
6) Sandblasting
This process uses abrasives, such as sand or glass beads, to remove burrs and other imperfections from the surface of custom CNC machined parts.
