Precision CNC machining parts Machining techniques

In precision CNC machining parts cutting which involves tools such as the saw. The shears whose role will be the cutting of materials according to predefined shapes and dimensions. Drilling also belongs to the category of the most common machining techniques. This involves creating round-shaped holes using a rotary device which will most often be fitted with two cutting edges.

Griding part in precision CNC machining parts

Grinding is common to apply a rotating device to the material to refine the finish applied to it if it is not a question of organizing a light cut on a machined part. Milling is intended to be a machining technique whose tools are intended to implement non-circular holes.

Apart from precision CNC machining parts, CNC also forms well-defined patterns on a given part. There is a combination of two movements. The first is to move the workpiece and the second is to rotate the cutting tool. Finally, we can also cite the turning which consists in using tools that take care of giving it the desired shape while this part turns on itself.

What are we talking about heat machining?

If the previously mentioned machining techniques are based on mechanical work, it should also be noted that machining can also be done using heat. It will then be a question of welding or burning the parts using different processes.

The first possible process will then be laser cutting which will melt the material treated by diffusing a high-energy light beam. The resulting finish of precision CNC machining parts promises to be both precise and of high quality. Added to this is gas cutting, which involves getting through the hardest materials by treating them with tools using gas mixtures such as hydrogen, propane, etc. with oxygen.

Plasma cutting and precision CNC machining parts

We can also talk about what is called plasma cutting obtained through the transformation of inert gas. It is most often common on electrically conductive materials. Finally, apart from mechanical machining. And heat machining, we can also talk about machining by erosion which uses either water jet or electric discharge.

The first technique of precision CNC machining parts relies on high water pressure and the use of an abrasive component to cut the part while the second is based on spark erosion. The application of electric shocks on the part. material processed.

Materials for precision CNC machining parts

Machining is intended to be one of the most classic processes found in the field of industry, we give you here the different types of materials common in machining. This is the method common in the manufacture of mechanical parts. It allows the design of raw parts from specific raw materials. The different types of materials common in machining are elaborated ahead 

1-STEEL; machining part

Steel occupies the first rank of the materials most common in machining because of its resistance, but also precision CNC machining parts flexibility. It is made of both iron and carbon to which vanadium is also often added if not chromium, so many materials can intensify its hardness.

Raw materials for precision CNC machining parts

Thanks to machining, steel becomes an exploitable raw material in the field of automobile construction and the manufacture of various machines and tools.

1. First, steel, one of the materials common in machining
2. Second, aluminum, one of the materials common in machining

2-ALUMINUM as precision CNC machining parts

Aluminum is also one of the most popular materials in the industry. This time, it presents malleable characteristics capable of resisting the phenomenon of oxidation. Aluminum is common in machining to develop lightweight parts.

3-TITANIUM in precision CNC machining parts

Titanium is like steel structures for precision CNC machining parts. With the difference that it can offer more lightness while maintaining its resistance. Its use in industry is justified by its high level of mechanical performance as well as its corrosion resistance capacity. All qualities which justify its higher cost on the market. Titanium, despite its limitations in terms of accessibility, lends itself quite well to machining.

4-MELTING CNC machining parts

Cast iron is a material that is obtained by alloying high carbon iron. Cast iron is therefore both very hard and quite markedly fragile. The machining of cast iron is generally done based on parts that have been the subject of a prior molding.

5-COPPER machining parts

Copper is also intended to be an essential material in machining. In precision CNC machining parts, it is characterized by its malleability. And is therefore once again a part of the malleable metals. The value of copper is that it is recyclable. It is therefore a durable material. Its machining is done for a wide variety of purposes.

• First, copper. One of the materials common in machining
• Second, Bronze. One of the materials common in machining

6-BRONZE AND BRASS role precision CNC machining parts

Bronze and brass have copper as a common component. While bronze is made of copper and tin, brass is formed from copper and zinc. Their property can be worked by adding other metals such as silver, lead, nickel, etc. The components of bronze and brass make their materials more resistant than copper and easier for the machine.

7-PLASTIC AND GRAPHITE

Plastic, whatever its nature, be it PVC, polyethylene, Teflon, etc. For precision CNC machining parts, it is also one of the materials common in machining, just like graphite, a mineral that is obtained from carbon and which is common in the manufacture of all kinds of industrial parts.

Prototype mold design in precision CNC machining parts

Because of the constant use of the series mold or prototype mold in the plastic injection process, it is easy to understand that its design and the choice of the type of mold constitute as many steps as possible to be carried out with the greatest care.

The prototype mold is generally common for small series of simple parts or to validate the design/industrialization before launching a series mold. This precision CNC machining parts material is both to ensure the quality of the injected part and to make the maximum economy in its modeling process.

Differences between prototype mold and serial mold

The prototype mold will be common in small batch manufacturing processes. Production on the basis of this prototype promises better results from a qualitative point of view. The processes that require this type of mold are numerous, which is good since it is an inexpensive masterpiece.

The prototype mold can be recognized by its standardized carcass and its steel components if not aluminum. This is a mold that responds purely and simply to the basic requirements of the design of injected plastic parts by precision CNC machining parts.
