What is high precision cnc machine aluminum turning?

cnc machine aluminum
The cutter used in cnc machine aluminum often includes many cutting edges, so it provides very high cutting efficiency, especially when applied in plane milling.

Characteristics of finished products after processing:

Finished metal products after machining, the surface usually has a gloss level of 4 – 6. The accuracy of the finished product is also at level 2 – 8. Milling can be applied to parts with high complexity, sheet metal with a thickness of more than 0.8mm.

Features of milling machine:

It is easy to apply on milling, reaming, drilling, reaming, chamfering or tapping operations… The rigidity of the milling machine is also much higher than that of the lathe and the operation is more stable.

Applying high mechanization and automation, however, the cost of the milling machine is high, so the investment cost is expensive, and the accompanying spare parts are relatively complicated.

Turning cnc machine aluminum method

– Turning is different from milling in that the main finished product usually has a round shape such as smooth shaft, step shaft, taper, thread, hole…

High precision turning, especially for fine turning

Lathe: Cnc machine aluminum is easy to operate; lathes have many different sizes, so they can be applied on many different size products. For long tape lathes, the rigidity is not very high.

The parts with high complexity or turning on the plane will make it difficult to turn.

Uses of milling and turning processing methods

The main use of milling is to process large and complex shaped surfaces. In addition, milling technology can also be applied to planes, inclined planes, keyway types, common grooves, complex or simple profiles. Milling also performs hole machining operations.

Machining turning

+ Machining of parts that can be shaped by the rotation of the workpiece.


+ Similarly, machining surfaces of single shafts, step shafts, cones, threads, holes, rotating circular profiles…

+ Processing all kinds of holes such as through-holes, non-through holes, threaded, threadless or profiled holes.

What is metal turning?

To put it simply, metal turning is a form of cutting metal workpieces by the movements of the turning tool and the workpiece. Unlike milling, the cutting motion in turning is the circular motion of the workpiece (different from milling, which is the movement of the cutter).

The workpiece movement combined with the vertical or horizontal tool translation will form the complete part.

With many advantages that it brings and high applicability, lathe is very commonly used in cnc machine aluminum. Currently, turning must account for 25 to 30% of the work in mechanical processing factories around the world.

Metal turning processing plays an extremely important role, an indispensable part of today’s life. Metal turning processing methods include 5 types: hole turning, outer cylindrical turning, head turning turning, cutting off turning, and threading turning.

Why use cnc machine aluminum turning?

The current method of cutting embryos includes many different types, each of which will have its own unique characteristics. The turning method is a specialized operation to shape parts with a circular shape, so when it is necessary to process details such as holes, gears, machine shafts, bolts, etc., there is no method that can convenient replacement.

Currently, with the advent of current CNC lathes, it has helped lathe machining to overcome the disadvantages, increase the accuracy of metal workpieces after machining, and also improve turning productivity a lot.

Therefore, turning is increasingly becoming one of the cutting operations with the highest application rate in mechanical machining.

Features of cnc machine aluminum turning

With wide applicability, cnc machine aluminum presents in most mechanical processing facilities worldwide, the turning machining method has a number of characteristics as follows:

In turning machining, there will be two movements: The main movement is the rotation of the metal workpiece. The remaining motion is the reciprocating motion of the blade.

– Turning is different from milling in that the main finished product usually has a round shape such as smooth shaft, step shaft, taper, thread, hole…

– Turning processing method has high productivity, the versatility of turning is large.

– High precision turning, especially for fine turning.

– Lathe: Easy to manipulate and operate, the lathe has many different sizes, so it can be applied on many different size products, so that the lathe products are very diverse. For long tape lathes, the rigidity is not very high.

– The parts with high complexity or turning on the plane will make it difficult to turn.

Advantages and disadvantages of metal turning

As the most applicable process, metal turning will certainly have many advantages and disadvantages. Some of the advantages of turning machining methods are:

– The advantage of the first turning machining is that it is high accuracy; the lathe is applied technology, so it helps to both improve the accuracy of the finished product and improve the turning productivity.

– Most types of lathes will have many sizes, so the finished products of turning machining are also very diverse. The operation and operation of the lathe is also very simple and easy.

– For products with a round shape, there is no more suitable method than turning.

– The universality of the large lathe.

In general, the cnc machine aluminum turning method will have some of the above advantages; this method is increasingly improved in technology, so productivity and quality are also increasingly improved.

Disadvantages of metal turning method

Besides the above advantages, convenience also has some disadvantages such as:

– Turning productivity always depends on many factors such as turning tools, processing materials, skills of lathes… Just one of the factors is not guaranteed to reduce productivity.

– In addition to productivity, the accuracy of turning also depends on the above factors.

Turning the outer surface

It is the most used and most popular turning method in mechanical processing units among cutting operations. This method helps to create a cylindrical surface with turning tools (straight knives, shoulder knives, curved cutters). For external cylindrical turning, depending on the type of part, the lathe will use different turning methods.

Convenient cut off

The vertical turning method is similar in nature to the outer surface turning but has more severe cutting conditions because the turning tool usually has less strength than the surface turning.

Convenience of naked face

Head turning is a method of turning the surface of a product. This turning method uses a wide variety of turning tools such as straight-head, curved-head, convertible or even shoulder-bladed knives.

Lace turning

Thread cnc machine aluminum turning is a relatively common turning method with a fairly simple operation. Basic tools can also easily perform threading without any difficulty.
