Precision, accuracy, and elegance -these are the most desired qualities custom CNC parts offer. That is why it is one of the leading manufacturing processes for creating sophisticated parts used in high-profile applications like the aerospace, defense, and medical industries. Nowadays, the market for CNC machining services is not only limited to industrial purposes, but it has also found its way to expanding at the consumer level, where day-to-day things are customized and produced in CNC machines for added value and intricacy.
You can definitely count on CNC machining when it comes to bringing your ideas into reality, whether you’ve got an idea of customizing your auto parts, decorations, and many other accessories. The parts created through CNC machining are highly customizable, thanks to the advancements of computer-aided design and manufacturing programs that any complex profile and feature are created. As long as you have the right tools and excellent programming skills, any design can be machinable.
5 In-demand Custom CNC Parts
You may not be aware that some of the beautiful and unique things you see might be created through CNC. You see, the possibilities for creating things through CNC machines are endless as long as the toolings and the machining capability allow it. Below are some of the most in-demand custom CNC parts:
1. Custom CNC parts – Weapons
Many hobbyists customize their weapons to add a touch of elegance and their personality to the weapons they own, be it knives, guns, and other weapons. CNC offers a limitless range of processes that make it perfect for creating these special parts. Besides the accuracy, it can also deliver beautiful and unique piece parts that will make up an elegant set of weapons. These may be customized through CNC in many ways. Below are some examples:
Custom-made handles, grips, and frames- most of the unique and attractive collector’s grips and handles for rifles and knives are made through CNC machining. These are initially designed through computer-aided software and then translated into a machining program that will enable the CNC to cut the preset custom requirements.
Custom-made barrels, compensators- these are some of the major gun parts that affect its accuracy and quality. Many manufacturers offer customization services for these parts to better improve a rifle’s overall performance.
2. Bespoke auto parts
Bespoke auto parts have one of the highest demands for custom CNC parts. The parts made through CNC can be divided into two categories, they may be made for functional use, and they may also be made for added aesthetics and unique design. CNC machining is very versatile in that it can provide for both use cases.
Functional parts or parts used to enhance a car’s performance require the high precision and high strength application that CNC machining is highly capable of. Additionally, CNC machining is also capable of producing personalized parts with ranging complexity.
Some examples of bespoke auto parts are some parts of the engine (pistons, intake manifolds, etc.), crankshafts, gears, stepping pedals, shift knobs, wheel disks, and many more.
3. Custom CNC parts – Furniture and Instruments
Yes, you read that right! CNC machining is not limited to working with metals. It can also be used for other materials like wood and plastics. Artistic furniture, and even instruments, with eccentric and intricate designs, can be made through CNC machining without having many problems with manufacturability and complexity. These parts can be made through wood lathes, milling machines, and CNC router cutting machines.
Examples would include table tops with attractive profiles, pedestals that are uniquely machined, beautiful centerpieces, bodies for electric guitars, necks for any stringed instruments, and many more.
4. Custom-made Accessories and Decorations
There is also a significant market for customizing different accessories and decorations through CNC machining. Elegance and intricacy have always been connected to CNC machined parts due to their desirable surface finish and their freedom for further finishing processes (e.g. anodizing, polishing, coating, etc.).
In this category comes anything you might think of, and these are: pieces of jewelry, metal coasters, customized keyboard keys, specialized cell phone cases, custom enclosures, machined busts, commemorative souvenirs, consumer electronic cases, novelty items, and the list goes on.
5. Special Replacement Parts
CNC machining has always been handy in providing special parts that are not already sold in the market due to many possible reasons. With the right reverse engineering process and design, any problematic part may be replicated and made as custom CNC parts.
There are many examples for this use case. Some of these are specialized sleeves and bushings, shaft keys, non-standard gears, cams, special fasteners, and many more.
How Are Your Custom CNC Parts Created?
Primary Machining Processes
Generally, a machining process involves gradually subtracting materials from a blank until you arrive at the desired shape. In actuality, it all starts with your idea, converted into a CAD design that will then be used to create the program responsible for commanding the CNC machine to cut your part. Below are the most important elements for custom CNC parts:
This stage is the start of converting your concept into a workable component. This can start with a sketch that will then be drawn into 3D modeling software. In addition to defining its physical appearance is the definition of the requirements needed for your part. These include the type of material you want to use, manufacturability constraints, and desired mechanical properties.
- CNC Program
After working on the design, next is the creation of the CNC program. There are many Computer-aided manufacturing softwares available nowadays that can help you create a program for your machining operation. The elements in a CNC program are the feeds, speeds, tool path, and other machining parameters.
- Cutting Tools
Cutting tools play a significant role in successfully producing custom CNC parts; they are among the main players in CNC machining operation. They somehow dictate the finished quality (dimensional accuracy and surface finish) of the machined part.
One of the reasons why custom CNC parts are very versatile is that they can be finished or polished with a wide variety of processes. These include surface treating, superfinishing, coating processes, and painting processes.
