Why Is Aluminum The Ideal Choice For CNC Turning? Advantages Beyond Light-weighting

Having gone through our experience and the reliability of our guidelines, one might ask why in so many industries, aluminum is preferred for CNC turning. This is because of the multiple advantages of aluminum besides its lightweight nature.

Superior Machinability

Aluminum is generally very ductile, having a medium hardness, hence, in Aluminium CNC Turning, it is possible to use cutting speeds of more than 300 meters per minute, which is almost 50% faster compared to steel. Besides this, tool life increases up to 30%, and chips break easily without getting entangled in the workpiece affecting machining.

Diverse surface treatments

From anodizing to provide wear-resistant coatings in various colors, to electroless nickel plating for enhancing corrosion resistance, and sandblasting that yields a delicate matte finish, there are several surface treatments for aluminum parts. Such treatments go a long way in enhancing aesthetics and functionality for the given parts.

We don't just process aluminum, but we know how to bring full value to it through the design of processes.

Secrets Of Tooling: How To Choose Optimal Geometry In Case Of Aluminum CNC Turning?

Having overcome general machining challenges, one main factor which always influences quality in Aluminium CNC turning is the tool selection. Proper tool geometry stands out for making a big difference in significantly improving machining efficiency and accuracy of parts. Key points summarized:

• Large rake angle, sharp cutting edge: Reduces the cutting forces, allows smooth chip removal, reduces built-up edge, and avoids roughness on the part surface.
• Large chip flute space: Ensures that wide and curled aluminium chips can be smoothly discharged and do not tangle in a workpiece to damage machined surfaces, therefore ensuring continuity in machining.
• PVD coating and substrate selection: We recommend the use of either sharp, uncoated inserts or PVD coatings suitable for non-ferrous metals in order to maintain sharp cutting edge and prolong tool life.

We work closely with leading tooling suppliers to establish a set of tool and parameter libraries dedicated to different CNC aluminum alloys and part characteristics.

Material Selection Guide: Why Is CNC 6061 Aluminum So Popular?

Material selection is equally important after tool selection. Different aluminum alloys perform very differently in Aluminium CNC Turning. We analyze several commonly used alloys below to help you choose the right material.

Alloy Type	Core Characteristics	Applicable Scenarios
CNC 6061 aluminum (A96061)	"All-rounder," balanced in strength, corrosion resistance, weldability, and machinability.	Prototype parts, structural parts, everyday mechanical parts.
7075	"High strength representative," strength comparable with many steels but with poor corrosion resistance and weldability.	Aerospace high stress structural parts, high strength mechanical parts.
2024	2024 has a high fatigue strength, poor corrosion resistance, and usually requires aluminum cladding or coating protection.	Aircraft structural parts, parts subjected to repeated loads.
5052	Excellent corrosion resistance and formability, medium strength.	Sheet metal parts, parts for marine environments, decorative parts.

Our material engineers can support you in analyzing working conditions and allow you to make the best possible tradeoff between performance and cost, avoiding part failure or excessive costs due to inappropriate material selection.

If you are not sure which aluminum alloy to choose for your project, JS Precision's material engineers will analyze your working conditions and recommend suitable CNC 6061 aluminum or other alloys to ensure part performance and control the costs.

Case Study: JS Precision Aluminum Turning Helps Reduce Drone Weight By 35%

Having discussed many theories and methods, let's look at a real-world case to give you a more intuitive understanding of our capabilities. This was a collaborative project with one of the drone manufacturers where we solved the weight reduction challenge for our client through Aluminium CNC Turning.

Client Pain Points

This client is a leading domestic logistics drone manufacturer with a market share of over 30% in urban deliveries. This weight reduction requirement was directly related to whether their new model would pass the load compliance tests conducted by aviation authorities.

One logistics drone manufacturing company needed to cut the core motor mount weight to extend their new model's range. However, the currently used steel motor mount weighed 800 grams. Not only is it heavy, but it also costs as much as $150 per mount to manufacture, while the complex structure makes it difficult to achieve precision control.

JS Precision's Solution

1.Material Replacement: We recommended using CNC 6061 aluminum with T6 heat treatment, since this allows for weight reduction without loss of strength, to replace the original steel.

2.Structural Optimization: Our engineers worked in cooperation with the customer to redesign the structure, using a biomimetic ribbed structure based on a hexagonal honeycomb mechanical principle, optimized with 12 stress simulations. This removed excess material and maximized the amount of weight reduction while maintaining rigidity.

3.Integrated Manufacturing: A 5 axis milling and turning center was used for one-time clamping and forming, integrating 6 mounting holes and 4 sets of heat dissipation fins, to avoid multiple clamping operations and improve the precision of the parts.

Our Results and Value

It reduced the weight of the final part to 480 grams, down 35%, the overall rigidity increased 15%, single-part machining time went down from 60 minutes to 48, and the cost went down to $120.

With its improved battery life, the customer's new model received 25% more orders in the first quarter following its launch than the previous generation had in the same period, cementing our position as a long-term supplier for core components.

Customer's feedback: "The JS Precision aluminum CNC machining service is so much more than manufacturing, it's R&D collaboration.

FAQs

Q1: What surface defects may normally occur in aluminum turning, and how can they be avoided?

These are of the built-up edge type that creates surface roughness, involving a poor look and precision of the part. It is possible to avoid them very effectively by using sharp tools, high-pressure coolant, and increasing the speed of the cutters.

Q2: Why do my aluminum parts deform after machining?

The reasons are usually due to excessive clamping force, the concentration of heat during cutting, or even the release of internal stresses. JS Precision solves this by optimizing the clamping scheme, using cutting fluid, and stress-relief annealing.

Q3: What are the main differences in aluminium alloys 6061 and 7075 with respect to machinability?

6061 is softer and more viscous which makes chip breaking a bit more difficult but tends to reduce tool wear, the 7075 is harder and more brittle resulting in a better surface finish, but requires a stronger cutting edge.

Q4: What is the largest size of aluminum parts that you can machine?

Aluminum bars are processed on our lathes in diameters ranging from 1 mm to 300 mm and lengths up to 500 mm to accommodate most size needs.

Q5: What are the special design requirements for anodizing aluminum turned parts?

Avoid sharp edges, otherwise, unequal coating is apt to result. Liquid will not drain readily from deep holes or narrow grooves unless vents or flow channels are provided to assure coating effectiveness.

Q6: How to control the thread quality of aluminum turned parts?

Good threading tools, rigid machine tools, and proper cooling. For threads that are in high demand, we will employ thread whirl milling for better quality.

Q7: What are the certification reports provided for the aluminum materials?

Complete documents for compliance purposes are supplied, which include material certificates, heat treatment reports, mechanical property test reports, and full-dimensional inspection reports.

Q8: What are the advantages of mill-turning compared to conventional turning followed by milling?

The advantage is single clamping, which means higher precision and shorter lead times. It eliminates the positioning errors of the several clamping operations, decreases logistic and waiting time, and as a result, increases efficiency.
