Highly precise and economical Custom CNC machining Services at DEK

What Is Custom CNC Machining?

Custom CNC machining creates parts that do not exist anywhere else. These parts can be produced using different types of CNC machines including CNC turning, CNC milling, and EDM, and others. A custom part can vary in size, dimension, and material used to create that part. Almost every industry requires custom CNC machined parts in their manufacturing cycle. If the manufacturer needs accurate CNC parts that are complex to create using the traditional machines, custom CNC machining could be the answer for them.

What Are The Advantages Of Custom CNC Machining?

In manufacturing, custom CNC machining is the most important part. It offers different techniques to create parts best suited for your applications. The CNC machines in contrast to manual machines can extremely improve accuracy, increase production speed, enhance safety, expand efficiency, and most importantly can reduce the cost. Below mentioned is the detailed advantages of custom CNC machining:

• Consistent product quality with accuracy:

Custom CNC machining is more precise than manual machining and can be repeated to create the same parts in large quantities over and over again.

• Increased production efficiency and speed:

This process is automated and computer-controlled, therefore increased the speed of the manufacturing. Machines do not tire and need rest which makes it more efficient than manual machining.

• Safer than the manual machines:

CNC machines are safer than manual machines because these machines work in close and guarded transparent doors.

• CNC machining is cost-effective:

Traditional machining requires a separate operator for each machine. Multi CNC machines can be controlled by a single skilled operator at one time. Because of the accuracy of the CNC machines, it also reduces the error and eliminates unnecessary wastage.

What Custom CNC Material Costs?

When calculating the cost of custom CNC machining, considering the material cost is crucial. There are several materials used in CNC machinings like metal and plastics. Materials with the dimensions of 6” x 6” x 1”, has the below-expected costs:

Metals

• Stainless Steel
• Aluminium 7075
• Aluminium 6061

Plastic

• Nylon
• POM (Delrin)
• ABS

Also, there might be wastage while machining the parts because of the subtractive nature of the CNC machining manufacturing process.

How Much Does Custom CNC Machining Costs?

It totally depends upon running different CNC machining. The hourly rate for the 3 – axis milling machine is approximately around $40, for CNC turning, the cost is about $35 per hour and for the 5-axis machines is anywhere between $80 to $120/hour or can be higher.

What Type Of CAD Files Are Accepted For Custom CNC Machining?

There are many CAD file formats used in the computer manufacturing process and these files are also employed interchangeably in different manufacturing processes like CNC machining, sheet metal fabrication, and 3D printing. Although, certain files are only accepted for specific processes. 3D fil format number are as many as there is 3D modeling applications. Below mentioned formats are the most popular formats used in custom CNC machining:

• SLDPRT (SOLIDWORKS)
• IPT (Autodesk Inventor)
• PRT (Siemens)
• 3DXML | CATPART (Dassault Systems)
• X_T | X_B (Parasolid)
• PTC (PTC)
• SAT (ACIS)

There are also other formats called standard non-proprietary. They are created for the ease of sharing and they are also compatible with popular CAD software. These formats are:

• STEP also known as STP, this 3D file format was created by ISO (International Standard Organisation)
• IGES is an interchange file format which is created by the US air force. IGES files have a .igs or .iges file extension.

STEP and IGES file formats are popular because CAD software allows you to save files directly in these formats.

What Are The Custom Types Of CNC Machining?

Below mentioned are the types of custom CNC machining:

• CNC Turning:

CNC turning machines can create internal and external features on the parts including drilled holes, broaches, bores, reamed holes, slots, tapping, and threads. Parts made through CNC turning are screws, shafts, and bolts.

• CNC Milling:

It is characterized by its ability to rotate the cutting tool while holding the material workpiece still. CNC milling can produce a wide range of shapes including shallow, cavities in the workpiece and flat surfaces and its peripheral milled features can also create deep cavities such as threads and slots.

• CNC Laser Machines:

CNC laser machines are used in the decorations and parts making of machined components. For example, when it is difficult to print the logo on the machined component the laser machine is employed for the engraving of the logo.

• CNC EDM:

CNC EDM is mostly used to create precise micro holes, tapered features, slots, and other more complicated features. It is typically used for hard metals that are difficult to machine to the desired shape.

• CNC Plasma Cutting Machines:

CNC plasma cutting machines are employed for many reasons, one being cutting the materials. CNC plasma performs this operation by using the high-power plasma torch which is controlled by the computer. Steel, stainless steel, aluminum, copper, and brass material are cut using the CNC plasma cutting machines.

Why Is It Essential To Use Custom Machining Services?

Custom CNC machining is essential in producing precise parts for the customer’s specific application and design needs. Custom machining is ideal in the following situations:

For the parts that can’t be found on the shelf: Some parts are difficult to find in a catalog or may not exist. Custom CNC machines help to create those parts to bring the new designs to life.

For meeting the requirements of special applications: Custom CNC machining is ideal for parts that have unique features like multiple elements combined to form the single component, texture engraving, and for adding other features which are not found in the standard components.

For short lead-time: This method offers a short lead time in creating parts that are unique and difficult to find in the market. Keep manufacturer away from the hassle of sourcing, you just need to engage with the custom CNC machining service provider to produce the part o your behalf to reduce the time for sourcing.

For low-volume production: Custom CNC machines are employed for the lower order volume requirements as compare to standard parts, making it easier to order one time small order.
