CNC can process metal materials (CNC machining aluminum alloy)

General CNC processing usually refers to the computer digital control of precision machinery processing, CNC machining lathe, CNC machining milling machine, CNC machining boring and milling machine, etc.
CNC also known as computer gongs, CNCCH or nc machine tool is actually Hong Kong there's a term, then was introduced into China, the pearl river delta is CNC milling machine, and in jiangsu area to be called "CNC machining center" a kind of mechanical processing, is a new processing technology, main job is processing program, the original manual work to computer programming.Experience with manual processing is required, of course.

CNC machining advantages
1, greatly reduce the number of tooling, processing complex shapes of parts do not need complex tooling.If you want to change the shape and size of the parts, you only need to modify the parts processing program, which is suitable for new product development and modification.
2, the machining quality is stable, the machining accuracy is high, the repetition accuracy is high, adapt to the processing requirements of aircraft.
3, the production efficiency is higher in the case of multiple varieties and small batch production, which can reduce the time of production preparation, machine adjustment and process inspection, and reduce the cutting time due to the use of the best cutting amount.
4. It can process complex surfaces that are difficult to process by conventional methods, and even some unobservable processing parts.
5, the disadvantage of CNC processing is that the cost of machine tool equipment is expensive, and the maintenance personnel are required to have a higher level.
In the future, in addition to providing 3D printing services for users, the workshop will also provide services such as mold opening injection molding, silicone duplex molding, and CNC processing, among which the main materials for CNC processing are as follows:
Aluminium alloy 6061
  6061 aluminum alloy is produced by heat treatment and pre-tensile process of high quality aluminum alloy products, its strength is not compared with 2XXX series or 7XXX series, but its magnesium, silicon alloy characteristics.
Material advantages:
It has excellent processing performance, excellent welding characteristics and electroplating, good corrosion resistance, high toughness and no deformation after processing, dense material without defects and easy polishing, color film is easy, excellent oxidation effect and other excellent characteristics.
7075 aluminum alloy
7075 aluminum alloy is a cold-treated forging alloy with high strength, which is far superior to mild steel.7075 is one of the strongest alloys commercially available.
Material advantages:
General corrosion resistance, good mechanical properties and anode reaction.Smaller grains allow for deeper drilling performance, increased tool wear resistance, and exceptional thread rolling.

Pure copper (also known as red copper) is a highly conductive ductile metal with a rose-red surface.It's not pure copper, it's 99.9 percent copper, and some other elements are added to improve the surface and properties.
Material advantages:
It has good electrical conductivity, thermal conductivity, ductility, deep drawing and corrosion resistance.
The electrical conductivity and thermal conductivity of red copper is second only to silver, widely used in the production of electrical and thermal conductivity equipment.Copper in the atmosphere, sea water and some non-oxidizing acid (hydrochloric acid, dilute sulfuric acid), alkali, salt solution and a variety of organic acids (acetic acid, citric acid) has good corrosion resistance, used in chemical industry.
Have good weldability, can be cold, thermoplastic processing into a variety of semi-finished products and finished products.In the 1970s, the production of copper exceeded the combined production of all other copper alloys.
Brass is an alloy of copper and zinc. Brass composed of copper and zinc is called ordinary brass.
Material advantages:
It has high strength, hardness and strong chemical corrosion resistance.There are also machining mechanical properties are more prominent.
Brass has strong wear resistance.Special brass is also called special brass, which has high strength, high hardness and strong chemical corrosion resistance.There are also machining mechanical properties are more prominent.Seamless copper pipe drawn by brass, soft and wear resistant.
45 # steel
45 steel is GB in the name, also called "oil steel", the steel has higher strength and better cutting machinability.
Material advantages:
It has high strength and good machinability. After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance. It has convenient material source and is suitable for hydrogen welding and argon arc welding.
40 cr steel is introduced
40CR is the GB standard steel number in China. 40CR steel is one of the most widely used steels in machinery manufacturing industry.
Material advantages:
It has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity.The hardenability of the steel is good. In addition to quenching and tempering treatment, the steel is also suitable for cyaniding and high frequency quenching treatment.Good cutting performance.
Q235 steel is introduced
Q235 steel is a carbon structural steel, the Q in the steel number represents the yield strength.Normally, the steel is used directly without heat treatment.
Material advantages:
With the increase of the thickness of the material will make its yield value decreases, due to moderate carbon content, good comprehensive performance, strength, plasticity and welding properties are better matched, the most widely used.
SUS304 steel
SUS304 refers to 304 stainless steel, which has the characteristics of good processing performance and high toughness.
Material advantages:
Has good corrosion resistance, heat resistance, corrosion resistance, low temperature strength and mechanical properties, stamping bending and other thermal processability is good, no heat treatment hardening phenomenon, no magnetism.
