Advantages Of Different Surface Treatment Of Metal CNC Machined Parts

CNC machining produces parts that have tight tolerance and very fine details from different plastic or metal materials. The subtractive nature of the machining however leaves minor marks on the surface of the parts and finishing is therefore necessary to improve in the surface roughness, wear resistance or the visual property of the parts. There are different surface treatments for the metal parts that are CNC machined and each comes with its own advantages. Below is a brief overview of the most common surface finish treatments and their advantages.

Powder coating

This surface treatment for the metal parts adds thing protective polymer layer on the surface. The coating is wear resistant and string finish that is highly compatible with all metal materials. The process is very similar to spray painting only that the paint in this case is dry powder and not the usual liquid. To increase corrosion resistance, the parts are primed with phosphating or chromating coat before the dry powder coating is done with an electrostatic gun. It is then cured at high temperatures. Multiple layers can be done on the parts to create thick coating depending on the preferences or requirements for the metal parts.

The advantages

• It has higher impact resistance especially compared to anodizing


• It is available in multiple colors


• Compatible with most metal materials


• Offer strong wear and corrosion coating for different functional applications.

Bead blasting

This surface finishing treatment adds matte or satin finish uniformly onto the surface of the CNC machined parts thus removing the marks in the process. Small glass beads are presented to the surface with the help of a pressurized air gun removing small amounts of material and smoothing out the surface. Surface features such as holes are masked so that dimensional changes are eliminated. This treatment is however best for visual purpose the end result will depend on how skilled the operator is. The glass beads are available in different sizes.

The advantages

• It is a low cost surface treatment method


• It offers uniform satin or matte finish for the metal parts

Anodizing

In this surface treatment, a thin ceramic layer is added onto the surface of the metal parts to offer protection from wear and corrosion. The added anodize coating is usually electrically non-conductive and is very hard. This treatment is mostly compatible with titanium and aluminum parts. The parts can be dyed to different colors depending on the requirements and sealed to give them that aesthetic appeal. Coating thickness can also be altered by variations in solution temperature, consistency, electric current and anodizing time. It is also important to know that the anodizing can be in type II or type III the difference usually being the thickness of the ceramic coating.

The advantages

• It offer aesthetically pleasing and durable coating


• It can be applied easily even on internal cavities and small sized parts


• It provides good dimensional control


• The coating is high wear resistant making it suitable for top end engineering applications

CNC Machining Company in China

The manufacturing sector is one of the most important as it ensures the smooth functioning of other businesses. This sector uses different machining techniques. It includes manual and CNC machining. The latter is most preferred because of the benefits it comes with. CNC stands for Computer Numerical Control. CNC machining is basically the process used in the manufacturing sector involving the use of computers and computer programs to control machine tools. Some of the manufacturing tools that can be controlled include routers, mills and grinders.

Precision machined part

Milling

CNC milling is precise with fast removing materials in three dimensions so that the desired part shapes can be achieved. The technology is precise and highly efficient, making it very popular. With this kind of milling, vertical, horizontal, bench top, face, bridge port, high speed and custom millings can be enjoyed. CNC milling services can handle all kinds of metals in addition to plastics.

Grinding

Precision machining uses surface grinding machines to cut tiny material amounts to create finest flat surfaces to tight tolerance. This helps makes accurate and absolute components. The different material types determine the precision ground part surface finishes that will be achieved. Angles, flats and radii on customs and components can be achieved with CNC grinding. The grinding process is however one of the most expensive in machining processes. The accuracy however makes it worthwhile.

Apart from CNC milling and grinding, other services that can be enjoyed include CNC turning, tapping and CNC cutting. EDM wire cutting services is another type of service offered here. The EDM services are important in manufacturing to achieve close tolerance for small part batches and components.

The Benefits of CNC Machining

CNC machining can handle different kinds of materials, including metals and hard plastics. It can work with aluminum, iron, stainless steel, copper, carbon steel, bronze, brass, sterling silver, titanium, acrylic polystyrene, carbon fiber, fiberglass, nylon and Acetal as well as polycarbonate among other materials.

The process offers precision machining which can be hard to achieve with manual kind of machining. This makes it possible for all kinds of shapes to be achieved for different manufacturing needs.

This process makes it possible to produce complex shapes that are impossible with manual machining. They include 3 dimensional shapes required in different manufacturing fields. Any business will find the machining effective enough to achieve the desired results.

With CNC machining, the same processes in milling or grinding or any other service can be repeated over and over again to get shapes and components that are exactly the same. It eliminates errors and reduces the work volume significantly compared to manual machining.

Best Service

When looking for precision machining supplier, always look for a provider who has a wide variety of services to offer that will cater to your manufacturing needs or requirements. Efficiency, skills and customer service are some of the other considerations you can make when choosing a company. Consider the service pricing as well to get high quality that you can afford.

How to reach lower costs at CNC machining production?

Computer numerical control or CNC is the automatic working of machine tools with the help of pre programmed movements of command in computer. The cost taken in setting the computers and completing the process and expensive. And by the time a product reaches to a consumer, the cost has raised highly which can lead to fall in sales. But there are ways through which you can cut back on the cost of production.

CNC machining mass production

Reduce machine timing – If you calculate the main work of cutting the materials takes less time but the machine continue working for a long time doing other works that does not. You need to cut out on the time that the machines spend on non value added activities like computer errors or the loading process, etc. If you reduce the time limit of machine and use it only in the cutting process it will save your electricity bill and the life of your machines. It will lead more productivity. The less time machine spends working the more profitable it will be for your pocket.

Reduction in material cost – The price of every product varies and depends on its making and availability and its demand. Different companies charge different rate on the same product. For example you need pipes in your work. One company offers you a set of pipes for 100 bucks and another branded company is offering you the same pipe but because of its brand, is charging you 300 bucks. Then it will be wiser to choose the former. But you must make your choice depending on the quality of product. If the quality and performance of expensive product is good, which the low cost product fails to provide then you should choose the good one. Low cost materials like aluminum, plastic, etc are good in long run.

Expand CNC walls – The thickness of the walls also plays an important role in your final cost. A wall with less thickness can led to increase in costs. The walls with should be 0.794mm. Remember not to make it too thin or else it won’t be able to hold up. If too thin walls are needed then you can use steel metal instead. It would be a good substitute.

Produce more of the same product– More quantity can reduce your making cost & increases effective production. If you make more of the same part the labor that goes its production will go down. If you are making multiple parts of the same product you need not change the settings, the same program will be used again and again. But remember not to over produce.

Carefully handle the parts – Material parts that are heavy requires more labor and cost. The whole process of loading and unloading them and then fixing them is tricky. And by mistake if it gets damaged then you can count it as a huge loss. It is better to buy separate parts of heavy materials and machine each one of them separately.
