After the CNC machining services, the machined part would usually come with a surface as-milled. To enhance their Outlook and feel, extra finishing may have to be done. Note that this would depend on the machined part. Some machined parts are used just as they were machined.

There are different levels of CNC machining surface finishes. They include the type II anodizing, standard finish (as-milled), bead blast finish, and powder coat finish. Let’s go over them one after the other.

Different Types of CNC Machining Surface Finishes –

1. Standard finish (as-milled)

The standard finish is called the standard finish for a reason. This is because it’s the exact way you have it from the CNC machine. It comes out with a roughness of about 125 uin and some minor tool marks. While some metal surfaces can be left this way, depending on the job, some may have to be smoothened even further.

Manufacturers can decide to reduce the roughness to about 32 or 16 uin. However, it would attract more cost and more operating time.

2. Anodizing (sulfuric acid anodizing) type II

After the CNC machinist services, anodizing is done to coat the metal with a corrosion-resistant coating. Afterward, the metal is dyed into gold, black, or red. This method is usually done for aluminum parts.

3. Bead blast finish

The bead blast finish is done by simply blowing glass beads against designated areas of the metal part. This procedure helps to create a light texture with a matte finish. However, it can attract additional costs in case the design needs specific masking of holes and surfaces.

4. Powder coat finish

The powder coat finish, in the opinion of experts at CNC machining services, is by far the smoothest finish ever. The process involves spraying paint all over the surface and then taking the sprayed surface and placing it in the oven to have the paint firmly latched on the machined surface.

The result is wear and corrosion resistant and is more effective and efficient than other painting or polishing methods. This method is majorly used in military equipment.

Other types of surface finishes include the following:

• Abrasive finish
• Grinding
• Polishing
• Burnishing
• Mass finishing
• Vibratory finishing
• Tumble finishing

How do you know the right surface finish to use?

As mentioned earlier, not every surface finish will work well with every metal material. Below is a short guide on choosing the right surface finish.

• Understand the measurements of the surface finish
• Pick the appropriate feeds and speeds
• Keep the rigidity of the tool up by reducing deflection and chatter
• Make use of chip breakers
• Reduce run-out
• Reduce vibration
• Use a positive take, sharp inserts, and lead angle.
• Avoid using the same finishing and roughing tool.
• Don’t ever cut down the centerline
• Steer clear from dwells and pauses.

Conclusion

Carrying out CNC machining services would be far more rewarding when you know just when to apply the right machining surface finish. I hope this guide has shown you a better way to do just that.

One of the most critical decisions that you’ll ever make as a manufacturer is choosing the correct CNC machining provider. It’s a decision that will come a long way with long-lasting effects. In fact, the effects can be both negative and positive.

Positives effects are merely building a long-term as well as a profitable relationship with your provider. On the other hand, the negative effect could be losing a lot of money on extremely poorly manufactured components.

Therefore, it’s inevitable that you chose your CNC shop carefully. Here are some of the things that you need to consider to come out on top with your decision:

Quality and Precision

The main point here is that it’s all about machine work, and hence it’s a no-brainer to focus on precision and quality. Of course, each provider claims to produce precise and high-quality parts, but you must be watchful.

You must look for providers that openly emphasize precision on their site, marketing materials, and even one-on-one. Also, their confidence should be backed up clearly by performance.

Also, ensure that the provider is willing to take full responsibility for their quality of work.

Vast Knowledge

Your provider should have an in-depth knowledge of various aspects of CNC machines. In fact, they should be aware of almost everything, if not everything, from designing the product to prototyping as well as manufacturing.

You should make sure that the provider knows ways around a plethora of CNC equipment to be sure that they’ll recommend the correct CNC machines in line with your budget and product.

Location

What’s the geographical location of the CNC machining service provider?

It’s one of the factors that you must never forget to consider since you will need to know exactly how close they are in relation to your company. It a no-brainer that a nearby provider will help you to significantly reduce costs as well as makes it easier to seamlessly communicate precisely and quickly.

However, you can take advantage of the power of the internet to choose your provider from anywhere across the globe, but a provider within your area is the best recommendation.

Capabilities and Experience

The capabilities of the provider are equally essential. It doesn’t matter what you may be interested in, but all you want is a provider that is capable of producing whatever you may need according to your specifications.

Moreover, the company should have vast experience. Usually, a company that has been operational for several years tends to have a reputation to keep. Therefore, that’s the sort of provider that you can consider.

Material Workpiece

Various CNC machining companies work on different materials. Therefore, you must ensure that you select the right provider with the ability to work on the material that you need for finished parts as well as components.

Extra Services

A good CNC machining service provider is the one that offers some additional services. That way, it will help you to save the extra money of looking for other vendors for each service.

Nevertheless, you need a CNC machining provider that saves you money, time, effort, as well as providing practical manufacturing solutions.

Metal fabrication is one of the many metal processing techniques adopted in the manufacturing industry. Fabrication could be achieved via several known methods, and each method has its uniqueness. Metal casting is a popular fabrication method that has been in use for ages in the manufacturing sector.

Metal casting has evolved in so many ways due to advancements in technological innovation, and these new methods guarantee efficiency. Each metal casting method adopts a specialized approach that suits the properties of the metal. However, there’s a need to know the benefits of each metal casting method to identify the particular one that suits your production line; this article highlights the various metal casting methods and their unique benefits.

Sand Casting

This method of casting adopts the use of synthetic or natural bond sand for effectiveness. This method of casting allows for solidity as the grains of sand are packed together to form a smooth molding surface. Furthermore, sand casting allows a moderate level of flexibility in the cooling phase to reduce the possibility of cracks and tears in the product. Often, clay is added to the sand particles to boost the bond between the particles. The sand casting method is popular in the production of automobile parts like engine blocks and some other vital housing products.

Plaster casting

Plaster casting is quite similar to sand casting, but there are a few differences in the materials used. Here, sand is replaced by a mixture of strengthening compounds, gypsum, and water. The mix of these materials ensures every corner of the mold is filled. Also, anti-adhesive compounds are applied to the content to ensure it doesn’t stick to the mold afterward. Plaster materials require partial or total fixing when used as most parts of the mold form cracks after using it to cast a section.

Die Casting

This method of casting adopts the use of non-ferrous metals as well as alloys like aluminum, copper, and tin. It involves the subjection of the materials to intense pressure to give the material the desired shape. Right before casting starts, the mold is painted with lubricant to ensure the content can quickly be ejected upon solidification; the coating also helps in the regulation of the die’s internal temperature in the pressure phase. Subsequently, molten metal is injected into the cast while it’s been subjected to intense pressure. The pressure phase is quite rapid to ensure the material doesn’t solidify before being appropriately cast. Upon completion, the content is carefully ejected, and metal scraps are removed from the product. Die casting guarantees a certain level of precision in the material’s consistency; this method of casting metal also lowers the need for post-casting machining of the product.

Investment casting

This casting method involves the use of wax in creating each part of the product. The wax is usually injected into the mold before the composite material is poured into the mold and allowed to form.

Final thoughts

The casting method of production remains one of the most utilized in the manufacturing industry. There are various casting methods, and this article highlights each casting method as well as the processes involved in each technique. Rapiddone offers some of these highlighted molding processes.
