What is an Aluminum?

Aluminum is a lightweight silvery-white metal that is versatile. It is the abundant metal on the planet earth and it constitutes approximately 8 percent of the crust. The density of aluminum is 2.7 g/cm-3, which is approximately one-third of the weight of steel. It is used in the strength to weight ratio in aerospace, automotive and electronic industries. It is self-resistant to corrosion because of its thin oxide layer. Aluminum is also an efficient conductor of electricity and heat, approximately 60 percent as efficient as copper. It is one of the most sustainable recyclable materials with a rate of more than 90 percent.

Aluminum Screw Manufacturing Process

The production of aluminum screws at CNCSwissMasion includes high precision and quality standards. All steps are done to guarantee durability, tight tolerances, and outstanding performance. The process produces screws with extremely low tolerances of up to 0.005 mm in difficult applications.

Step 1: Bar Preparation and Material Selection

The process starts with high-grade aluminum alloys being chosen including but not limited to 6061, 7075, 2024 or 5052. These materials are strong, resistant to corrosion and machinable. Aluminum bars are normally between 6 and 12 mm in diameter. Technicians slice them into manageable lengths by Swiss lathes. Bar ends are machined using chamfers so that feeding is smooth and machining does not cause instability in production.

Step 2: CNC Swiss Preparation and Programming

Then, experienced engineers develop the appropriate CAM programs based on customer CAD files. These programs specify tool paths, spindle speeds, and feed rates in order to achieve maximum accuracy and efficiency. Every CNC Swiss lathe is set to the minimum vibration and concentricity. Normal machining times are between 5-60 s, based on screw complexity and size.

Step 3: Swiss Turning (Precision Turning and Forming)

In Swiss turning, the guide bushing is used to hold the aluminum bar against the cutting tools. This arrangement reduces deflection and tight dimensional control. There are several tools that are used to turn, contour and groove in a single pass. The output is an ideal screw body and head, which are ready to be threaded or finished.

Step 4: Threading and Knurling Processes

Threading is done with accuracy thread-cutting tools or rolling dies. Threading is done to precision of pitch and fitting, and thereby the performance of the assembly is uniform. To increase grip or torque transmission knurling is applied to the head or shank. All operations are controlled to ensure geometrical accuracy and surface integrity.

Step 5: Milling, Drilling, and Secondary Machining

Swiss machineries also deal with cross-drilling, slotting, and small feature milling. In complicated geometries, CNCSwissMasion employs multi-axis mill-turn centers. Holes that are drilled usually have a diameter of between 0.8 mm to 6 mm. The step is necessary to make sure that every structural and functional detail is attained within exact boundaries.

Step 6: Stress Relief and Heat Treatment

Some alloys, e.g. 7075, are heat treated to improve stability and strength. The processes of aging and stress relief make distortion during use difficult. Every batch is processed as per the necessary temper designation which enhances the mechanical performance of the screw and its durability in the harsh environment.

Step 7: Coatings and surface Finishing

Screws are transferred to finishing and coating after machining. Anodizing is regularly used to improve the corrosion resistance and hardness of the surface. The last surface roughness is typically between 0.4 µm and 1.6 µm. Other alternatives are polishing, passivation, and color anodizing to protect as well as to appear.

Step 8: Quality Inspection and Metrology

All screws are subjected to rigorous checks in terms of dimensions and visual checks with CMMs, micrometers, and optical comparators. Diameter, thread pitch, concentricity, and surface finish are measured. Every lot of production is accompanied by detailed inspection reports and traceability documents to guarantee complete quality transparency.

Step 9: Packaging and Delivery

Lastly, screws are washed, packaged and shipped. Protective tubes, trays, or personalized boxes can be used to package the products to avoid damages during transportation. CNCSwissMasion deals with prototype quantities as well as large production runs of more than 100,000 pieces. Each delivery arrives to you as a fully assembled shipment.
