What Does Cnc Machine Stand For

CNC machining is the most widely used subtractive manufacturing technology. In CNC, material is removed from a solid block using a variety of cutting tools to produce a part based on a CAD model. Both metals and plastics can be CNC machined.

CNC machining produces parts with tight tolerances and excellent material properties, both for the manufacture of unique parts and prototypes as well as for the production of short and medium series.

How Does CNC Machining Work?

There are two main types of CNC machining systems: milling and turning. Depending on the geometry of the part to be manufactured or the process to be carried out, one system or the other or both will be chosen. Be-cu has machinery capable of carrying out both processes in an integral way.

How Does CNC Milling Work?

CNC milling is the most popular CNC machine architecture. In fact, the term CNC milling is often synonymous with the term CNC machining.

In CNC milling, the part is mounted on a moving bed and material is removed with rotating cutting tools(As CNC Milling Aluminum,CNC Milling Brass,CNC Milling Stainless Steel,CNC Milling Copper,Cnc Milling Titanium,And More).

The CAD model is converted into a series of commands that the CNC machine can interpret.

A block of material is then cut to size and placed on the bed, on clamps or fixtures. Precise positioning and alignment are key to making accurate parts, and special metrology tools are often used for this purpose.

The material is then removed from the block using specialized cutting tools that rotate at very high speeds. Multiple steps are often required to create the designed part. First, rough geometry is given to the block, removing material quickly with less precision. Then one or more finishing passes are used to produce the final part.

If the model has features that the cutting tool cannot reach in a single setup (for example, if it has a slot on the back), then the part must be reversed and the above steps repeated.

Next, if tolerances were specified on the technical drawing, the critical dimensions are inspected.

Most CNC milling systems have 3 linear degrees of freedom: the X, Y, and Z axes. More advanced systems with 5 degrees of freedom also allow rotation of the bed or head (A and B axes). 5-axis CNC systems are capable of producing parts with high geometric complexity and can eliminate the need for multiple machine setups.

How Does CNC Turning Work?

In CNC turning, the part is mounted on a turntable and the material is removed with stationary cutting tools. In this way, parts with symmetry along their central axis can be manufactured. Turned parts are generally produced faster (and at lower cost) than milled parts.

The code is first generated from the CAD model and a round, square or hexagonal block of material is loaded into the CNC machine.(As CNC Turning Aluminum,CNC Turning Brass,CNC Turning Copper,CNC Turning Stainless Steel and more)

The part begins to rotate at high speed and a stationary cutting tool traces its profile, progressively removing material until the designed geometry is created. Holes can also be made along the center axis, using center drills and internal cutting tools.

If the part needs to be flipped or moved, then the process repeats. Otherwise, the is ready for use or further post processing.

CNC turning systems (also known as lathes) are typically used to create parts with concentric profiles. Non-concentric parts can be manufactured using modern multi-axis CNC turning centers, which are also equipped with CNC milling tools. These systems combine the high productivity of CNC turning with the capabilities of CNC milling and can manufacture a wide range of rotationally symmetric (looser) geometries, such as camshafts and radial compressor impellers.

Be-cu.com at the pace of the modern world and today's industry, has implemented the use of small batch CNC machining processes for the manufacture of parts and products in the metalworking, injection, extrusion and vulcanizing areas, letting you know these 5 benefits of CNC machining .

CNC Machining is machineries by Computerized Numerical Control,that allow companies to be more productive, offer customers more optimal results, in the established time and even reduce costs.

At Be-cu.com, we are experts in CNC machining. We have the most advanced technology. Contact us at sales@pintejin.com for the manufacture of your machined parts.If you want to know more about this welding service, at BE-CU.COM we will be more than willing to serve you.

The Advantage Of Precision CNC Machining

Although in the metalworking industry, processes are still carried out manually, which we also carry out at Be-cu.com, the benefits of CNC machining are many:

1.Higher Accuracy

The fact that CNC machines are run from computer programs gives better accuracy compared to manually operated mechanical machines.

In addition, as the machines are controlled by software and programmed by an integrated computer, the machining processes are carried out in less time and with fewer errors, which undoubtedly improves productivity.

2.Fewer Security Risks

For operators and companies that offer these CNC machining, there is undoubtedly greater safety, in terms of risks, since workers are not in direct contact with the tools at the time of their operation, nor are they exposed to cutting tools.

3.Better Quality Parts And Products

Being a CNC software that executes the processes and operations, it has the ability to carry out the same process hundreds or thousands of times and with the same level of perfection, making mass parts and products or also special custom developments.

4.Less Waste Generation

One of the problems of the industrialized world is the disposal of waste. CNC machining helps reduce metal waste, due to the fact that they have better chip management systems resulting from machining or cutting processes, which usually accumulate in factories with other systems.

The system, by having an automatic removal of chips and cuts, makes for cleaner work spaces. In the specific case of metals, it improves the management of the cuts and makes maximum use of the material, and the chip residues can be recycled and reused.

5.More Complex Processes

With the use of CNC machinery, at BE-CU.COM we can develop much more complex processes(include swiss cnc machining and more), which if it were not for this system would require more effort and time.

The operators only program and supervise the machine and the processes, and later they collect the parts or products and remove the excess material, being a cleaner process and without failures.

BE-CU has all these advantages of CNC machines, which is why we can provide a precision machining service for bar turning, with the highest standards of quality, reliability and guarantee.
