CNC parts refer to the components manufactured with subtractive manufacturing technology by eradicating material from solid blocks utilizing a range of cutting tools to fabricate a final design. People refer to them as CNC machining parts, machined parts, bespoke parts, custom-made CNC parts, and more. These parts attain high accuracy, precision, and complexity, and are cost-effective.
Why use machined parts?
There are several reasons why product designers, R$D departments, and other professionals use machine parts, and several of the specific benefits are described in the next section. In summary, machined parts have superb robustness, since they’re made from solid blocks of materials, and can be created into a variety of thicknesses and shapes. Besides having exceedingly detailed features, they can be produced from a range of materials. Small amounts of machined components can be made swiftly, because they don’t need tooling, and tolerance can be exceptionally tight if machining paces are lowered.
Companies might also utilize machined components since machining is a tried-and-testing manufacturing method that has been accepted in the industry for years. Machined components are, therefore, likely to satisfy industry-specific certifications and standards.
What are the benefits of machined parts?
Machined parts provide certain advantages that might be impossible with, for instance, 3D printed parts or injection molded parts. Here are some benefits of machined parts.
No MOQ. One of the best benefits of machined components is the ability to buy them with no minimum order quantity. For molded components, it’s necessary to make metal tooling – a process that takes an extended period and generally costs a lot of money. Inversely, machined parts are cut directly from an empty workpiece, which makes it cost-friendly to order very small volumes or even one-off components. Certainly, needing a very huge amount of (plastic) components could imply molding is a better option. However, machining is virtually matchless in providing top-quality components with no MOQ, hence suitable for smaller businesses, prototyping, and small production runs.
Good prototypes. Some companies prefer to order injection molded prototypes; however, only big companies can afford to do so. The expenditure of tooling can make prototyping excessively costly. Machined components are appropriate and affordable as prototypes since they can be made as one-offs. Also, machining is much swifter than molding, meaning R$D divisions can rapidly iterate many versions of a component, and then put it through whichever assessment or testing is needed before moving to production.
Quality. Machined components can be fabricated to a very high standard. Maybe, more importantly, clients can specify tolerances that the mechanist must meet. This implies the machine operator or machinist can take additional time on tight tolerance machining components and individual features.
Strength. Machined components are sliced from solid parts of material referred to as blanks, which have generally been extruded or cast, making them stronger than 3D printed components, for example. Several machined components are also more robust than their molded correspondents because molded components must have thin walls, hence limited in regard to mechanical performance.
These are only a few ways in which you’ll benefit from machined parts. However, you’ll realize more benefits when you start using them.
