Why 4 axis machining is much cheaper than 5 axis machining

If you are about to buy a milling system then you must have done a survey in the market and found out that 4 axis is cheaper than the 5 axes. Let us know why is that.  First, learn about the similarities and the difference among them. Axis in a CNC machine is the number of motors being driven for positional control of the tool. So when a VMC i.e, vertical mining center has an additional rotary axis to it, then it becomes 4 axis machine. When a machine has 3 regular axis and 2 rotary axes, then it is called 5 axis machine. Both of them have three linear axes.

4 axis machining part

The 4 axis machine is virtually operated. They are easy to operate, comes with a manual with all the instructions on it and have computer lead operations. It can operate on anything – wood, aluminum alloy, PBC, composite board, foam which is a wide range. It is specially built for detail work and can be in different departments – creative art, industry, medical equipment creation, technology research, etc.

5 axis is right now being called the best mining right now. It is high in quality, can do drillings, and is precisely engraved. It can create parts. It can make military grade products, car molds, medical technology, artificial bones, door frames, etc. It can cut almost everything.

The reason you will find the rates of 4axis lower than 5 axis is that of its features and qualities. As mentioned above, there is a lot of difference between both. While 4 axis can perform much work it still is back in the competition. The detailing and finishing in work 5 axis can provide, 4 axis cannot.

Another reason for the difference in price is the usage. Being advanced  5 axis brings with itself complexity. Managing it is not an easy thing, while on the other hand, 4 axis is user-friendly. It is more common in any case compared to 5-axis. Just by going through the manual anyone can operate it. The parts are not complex and are easy to handle. It also comes with a turning axis. But in order to make 5 axis work, you have to learn a lot. 5 axis comes with computer set up and all the setting are pre-programmed into it. You have learned how to control it. Even a small mistake in it can create a lot of mischief.

If you are cutting along an arc with your manual machine, then you should switch to 4 axis. It makes your work a lot easier. It is usually used for either indexing mode or continuous mode. In the first it is indexed to a fixed degree, in the latter, it is continuously rotated to produce something. With 4 axis you can give shapes which otherwise is very difficult. It makes your job faster and does not demand much setup. A 4th Axis can be a powerful addition to your CNC arsenal.

Whatever you need be it 3 axis, 4 axis or 5 axis CNC machining company in China are the best for it. CNC machining in China are the best at making all kind of CNC machines. CNC machining China makes all kind of machined parts in a wide variety.

DIFFICULTIES OF MACHINING PLASTIC PARTS COMPARING TO METAL PARTS

Plastic has overtaken metals in the majority of the object manufacturing. Its feature like softness and expansion ability has increased its demand from customers. It can be molded into complex featured objects. Difficult holes and unbelievable curves can be carved out from plastics.

metal machining parts

Not all plastic is favorable for molding and precision machining parts. Plastic which has a high tensile strength and high compression strength can only be chosen for molding. For example, Nylon, Peek and Ultem are good choices, but Teflon is a complete no. Customers chose plastic keeping in view their requirement and cost.

Machining is a one of the various manufacturing process specializing in cutting plastics and giving them definite shape and size. Though plastics are soft and flexible it is not easy to mold into any specific part or object. In comparison to metal machining, it poses some challenges to the Chinese machining manufacturer. Let’s discuss some of these problems.

1. Plastics have a varied range of features – Unlike metals, plastics are man-made material. It is created by combining different components into a different ratio. All plastics are different with each other in consistency, strength, tolerance and color. Every customer wants to manufacture a different part with different characteristics which actually increases the technological complexity and cost while machining. Machining has to be set in the proportion of varied features each time when a customer demands something specific. Whereas metals have fixed characteristics where machining becomes fixed and easy with no variation required in design tools and customers also adjust with the features of metals making machinist’s work easy.

 

2. The plastic is soft making it difficult to mold – Metals are rigid and that is why they are easily compatible with machining as it (machining) is favorable to rigid materials providing more resistance to deformation. Plastics, whereas, are soft and pose a threat to machinist of going out of shape while machining it. During mold temperature and pressure is set very precisely as a minute difference in setting could lead to deformation in plastics and if there would be any dis-shaping of parts then it couldn’t be assembled properly in a final stage.

 

3. Handling is difficult – Plastic components are very sensitive, unlike metals which are rigid, tough and strong. So there is always a chance of mishandling the plastic components while machining which poses a danger to surface and corner damage. To avoid any such damage, machinist should be an expert in handling and manage the whole process in an excellent way.

 

4. Creates a large amount of scrap – Machining of plastics is different from metal machining as it produces a huge quantity of scrap while machining. It is easy to cut by tools and that is why complex designs are created by product designers. Complex designs have more curves, joints, holes which, when put into machining creates many pieces to be cut off from the plastic creating a huge pile of scrap. Metals are not easy to cut and therefore simple designs are carved out while machining which leads to less scrap creation.

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.

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.

cofbronze plated cnc machined parts

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
