WHY CNC MACHINED PROTOTYPES ARE MUCH MORE EXPENSIVE THAN MASS PRODUCTION PARTS

CNC machined prototypes are the most famous form of prototyping which gives accurate and precise model of the actual product. CNC prototyping allows high production speed and accurate representation of the final product. There is actually a wide range of materials available for CNC machining. The choice of the material used for making prototypes depends upon the properties required in the prototype. The tolerance of the CNC machined prototypes can be varied depending upon the choice of the material.

CNC MACHINED PROTOTYPES

WHY IS CNC MACHINING COSTLY?

The very first reason to explain the high prices for CNC machining is – tooling is really expensive. This makes volume processes unsuitable for prototyping. The materials used in additive manufacturing often don’t provide the required tolerances. Changing the materials frequently is a time taking process. So, most manufacturers use a single material with the machine. Sometimes secondary processing is required in order to achieve tolerances and get a smooth finish. This secondary processing makes the prototype lot more expensive. CNC machining services setup is a really complex process. A lot of thought and work goes in the setting up of CNC machines. The setup requires various special mills, drills and taps to be properly installed. This obviously increases the cost on manufacturers. Most of the CNC machines use heavy motors of industrial grade. In order to reduce cost all these sophisticated machines need to be used constantly. The process of making  prototypes does not allow the proper use of the machinery as the product is made individually. So you see, this is the major factor which accounts for the high cost of CNC machined prototypes.

WHY IS MASS PRODUCTION CHEAPER?

The mass production of goods is much cheaper due to several reasons. The very obvious reason for this is that much more products can be produced at the same time rather than making an individual prototype at a time. In the process of mass production, highly skilled professionals are really not required to carry out various operations and unskilled labor can do most of the jobs which obviously lead to decrease in labor costs and hence decrease in overall cost. Mass production makes it possible to present sufficiently more products to the buyers in less time. Mass production is faster, cheaper and more convenient than making a single prototype.

COST COMPARISON OF CNC PROTOTYPING AND MASS PRODUCTION

When products are made in mass production process only very few of them undergo the rigorous checking process in which the dimensions of the goods are checked. When a prototype is made, that single prototype is rigorously checked for all the dimensions. This obviously adds to the cost. Mass production makes a lot of products at the same time, whereas rapid prototyping makes only a single prototype at a time. This too increases the cost in rapid prototyping. The sourcing of materials in small quantities is a rather expensive process. Sourcing of materials on a large scale in the case of mass production reduces the cost. Hence mass production is lot more cheaper than the CNC machining of prototypes.

HOW TO HANDLE STEELS OF HIGH HARDNESS ON CNC MACHINING

The competition in the industrial world requires one to constantly come out with the newer, the better, and the more efficient technology which solves the problems of various production processes. Moreover, new materials are being worked with in various production processes, which one would have never imagined could be used for that purpose. In order to put such materials in various applications different methodologies are required.

REQUIREMENTS FOR MACHINING HARD STEEL

Hard materials like S7 steel and H13 steel are many a times required in molds due to their remarkable properties like impact resistance and temperature resistance. Although these hard materials improve the performance of the final products, but these materials require tough machinability. Machining hard materials seem almost impossible for many manufacturers. For machining hard materials one requires – A rigid tool system of high precision, tough and hard tool material, tool holders of high stiffness, proper and appropriate tool geometry and cutting conditions, etc. There is a huge difference in the machining process of hard materials and normal materials used for making molds. Working with hard steels requires the application of the right tools, right strategy and the right technology at right production stages.

TOOLS FOR MACHINING HARD STEEL

The right tools are required by productionists to machine hard steels. Working with hard steels requires one to have all the tool parameters accurately and precisely calculated. It is a must to consider well the sharpness and the edge measurements of the tool.

Square end, ball end and bull nose mills are used at different production stages. The mill with ball end does roughing and finishing operations. The mill with bull nose end is operated on large and flat surfaces. This tool is not so perfect as it gives rise to chipping. The corner parts of the material are processed by the mill with square end. These tools should be occasionally oiled and dry machining should be done with air to maintain their optimum performance.

RIGHT STRATEGIES

Working with hard materials requires the application of right strategy too. For instance, these days hard turning of the parts is done prior to the grinding to the final finish. Grinding process is specifically expensive and needs to be done in accordance with different shapes of materials. Now manufacturers are using various strategies to easily and swiftly turn a prehardened part. Insert selection plays an exceedingly important role in the process of hard turning. Selection of suitable insert is complementary to the process. For materials with much higher ranges of hardness, CBN inserts are used. Wear and tear of tools will necessarily require its maintenance like sharpening and hence the edges of the tool are varied. This variation needs to be accounted in the CAM programming. The best strategy used is the elimination of sharp turns and rather introducing small arcs at the corners in the program. This helps in the machining of corner parts and avoids the wear and tear of the machine. A sudden change of direction by 90 degrees slows down the machine.

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.

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.
