As one of the fastest-growing precision CNC machining services suppliers in China, the following machining capabilities at Krosino are available to serve your needs of CNC machining, from rapid prototyping to precision parts and tooling machining, to end-use production.
CNC Turning: a technology through which the material block fixed on the CNC turning center or lathe rotating with high speed, while the cutting tool moving into the rotating axis to process the workpiece, to get CNC turned parts with accurate sizes.
CNC Milling: generally regarded as the most common machining process, which refers to utilizing a CNC milling cutter to do circular motion and create milled parts with certain shapes and details in a stationary piece, including slots, holes, notches, grooves, etc.
CNC Drilling: a cutting process in which the workpiece is fixed, aligning the cutter center with the hole center and rotate to produce round holes, can be done on lathes and mills.
CNC Milling and Turning: a compound machining technology in which the cutting tool and workpiece are both rotating, to produce complex curved or special-shaped parts through designed multiple kinds of tasks.
Wire EDM: EDM parts from prototypes to full production with tight tolerance and complex construction.

CNC machining is a traditional manufacturing process that uses drills and turning tools to create a part by removing material from a solid block of material. This process is fast, highly repeatable, and ideal for creating parts with tight tolerances. CNC machining can be done with any material that’s rigid enough to machine ... from plastic to metal to fiberglass and aluminum is a popular choice among product teams.
Broadly speaking, aluminum is a strong, non-magnetic, cost-effective material that is highly corrosion-resistant.
Types of aluminum popular used for CNC machining:
1. Aluminum 6061-T6 CNC Service
6061-T6 is one of the most popular aluminum alloys on the market and most manufacturing companies offer it as the standard grade for CNC machining. It’s versatile, easy to machine, and 6061 can even have different heat treatments.
6061-T6 is an excellent all-purpose material applicable to a wide variety of use-cases. Even though this material has a good strength-to-weight ratio, it’s ill-suited for high-stress applications. Common applications include automotive parts like chassis, bicycle frames, valves, computer parts, and much more.
Mechanical specifications:
Ultimate tensile strength: 310 MPa
Elongation at break: 17%
Modulus of elasticity: 68.9 GPa
Hardness: 60 HRB
2. Aluminum 7075-T6
For high-stress or high-performance applications, engineers should consider 7075-T6. This grade of aluminum is well known for its excellent strength-to-weight ratio and its hardness can even be comparable to that of some softer steels.
Widely used for high-stress applications in the aerospace and military industries, common applications include aircraft fittings, missile parts, and fuse parts. Certain high-performance bikes and sporting goods also include parts made from aluminum 7075-T6.
Despite its high strength and excellent mechanical properties, 7075-T6 does have its drawbacks. This material is less ductile and less resistant to corrosion than other grades. What’s more, aluminum 7075-T6 can be prohibitively expensive for some product teams.
Mechanical specifications:
Ultimate tensile strength: 434 – 580 MPa
Elongation at break: 10-15%
Modulus of elasticity: 69 – 76 GPa
Hardness: 79-86 HRB
Maximum service temperature: 100 °C
3. Aluminum 6082
Aluminum 6082 has similar properties to aluminum 6061; however, 6082 has a slightly higher tensile strength. Further, this type of aluminum has the highest strength out of all of the 6000 series alloys and it’s exceptionally corrosion-resistant. 6082 is a good option for engineers who want more strength than what 6061 offers, but don’t want to invest in the 7000 series.
Aluminum 6082 is well-suited for general purpose applications that need an added degree of strength and toughness. This material is popular in the construction industry and can be found in many bridges, towers, and trusses. However, product designers should keep in mind that it’s difficult to produce thin walls using aluminum 6082.
Mechanical specifications:
Ultimate tensile strength: 140 – 340 MPa
Elongation at break: 6.3 – 18%
Modulus of elasticity: 69 – 71 GPa
Hardness: 35-56 HRB
Maximum service temperature: 130 – 150 °C
