Depend On Weimi For Turning Parts Made Out Of Aluminum

At Weimi, we have 22 turning machines, which can process products up to 150 x 200mm. The most commonly used is a numerically controlled one, using digital codes to control the tool to automatically process to a given working program, movement speed, and trajectory, and one of the biggest advantages is that machined parts are complex and have a high level of precision. At Weimi, our tolerance can reach plus or minus 0.002mm, and we can easily meet our customers’ processing requirements, whatever the implementation or timescale.

Aluminum alloy is the most widely used metal in aviation, aerospace, automotive, machinery manufacturing, shipbuilding, and chemical industries, and has low density but offers strength comparable to high-quality steel. It has good electrical and thermal conductivity, corrosion resistance and can be processed into various profiles, making it a truly versatile material.

Whilst aluminum alloy processing can be demanding, and difficult to perfect without pits, pores, scratches, or cracks on the surface, our customers ask for smooth, flawless turning parts. We’re able to make full use of our existing processing experience in machinery to offer the very best turning parts for a wide range of clients in a number of industries and sectors.



After years at the forefront of turning part manufacturing, we’ve found that CNC turning is the most suitable for cutting rotating parts with the following requirements and characteristics:

  1. Precision requirements
  2. Rotary parts with complex surface shapes or difficult-to-control sizes
  3. Rotary parts with good surface roughness requirements
  4. Rotating body parts with special thread



The benefits of aluminum parts machined by CNC turning

There are a number of reasons why aluminum parts machined by CNC turning are superior to alternatives. Perhaps the biggest is that it’s much easier to ensure the accuracy of each processing surface of the workpiece. During processing, the workpiece will rotate around a fixed axis, and every surface has the same axis of rotation, ensuring coaxiality (the tolerance for how closely the axis of one cylinder is to another) between the processing surfaces.

The second is that the cutting process is relatively stable. Except for intermittent surfaces, the lathe machining process is generally continuous, unlike milling and planing. During one pass, the cutter teeth will cut in and out multiple times. What’s more, aluminum parts that are machined by CNC turning are suitable for finishing non-ferrous metal parts. Aluminum belongs to non-ferrous metal and it has a low hardness and good plasticity. It is difficult to obtain a smooth surface by other processing methods. Finally, the turning tool is the simplest type of tool. It is easy to manufacture, sharpen and install. It is easy to choose a reasonable angle according to specific processing requirements, and aluminum is the preferred metal.

How we process aluminum at Weimi


Pure aluminum is easy to process, has good corrosion resistance, and can be made into various profiles. Due to its low strength, it’s not suitable for structural materials. Aluminum alloy is formed by adding certain elements to the basis of pure aluminum. It has high strength and excellent electrical and thermal conductivity. The most commonly used materials at Weimi are aluminum 6061 and aluminum 6063, and we select the most suitable processing materials for customers based on the role of parts and customer requirements.

When processing aluminum, we use a drawings analysis to formulate the processing plan. We then carry out manual programming and automatic programming using a mathematical process, writing parts processing, and programming inspection methods. As the machining objects of CNC lathes are mostly rotary bodies, three-jaw chuck fixtures are generally used, and the selection of lathe tools is a very important part of the process. We use different tools according to different shapes, and optimize clamping positions to extend the life of the tool.

We understand the importance of guaranteeing the sequence of operating parts on the machine and ensure that from the drawing to the formulation of the plan, the process is handled both independently and overseen to ensure quality and accuracy. What’s more, we’ll conduct rigouristic inspections at every stage, and use strong, durable product packaging to ensure goods are delivered to our customers in the best possible condition. This goes as far as wearing gloves to avoid leaving fingerprints and dust – it’s this attention to detail that has set us apart from other manufacturers and keeps customers coming back.
