CNC lathe machining process design requirements for aluminum profile parts
With the popularization of CNC lathe processing technology and the continuous improvement of product quality requirements, aluminum profile processing has been widely used in CNC lathe processing. The correct process and tooling design make CNC lathes have many characteristics such as high machining accuracy and flexible machining. Engine flywheels, precision parts processed from aluminum profiles are widely used. After solving it, our company will introduce you to some key points in process design, tooling design and general equipment selection of such aluminum profile processing parts.
The process is limited by the action function of the φ128mm hole of the machine tool and the φ50mm hole cannot be completed in the same process, and it needs to be clamped twice. Due to repeated positioning errors and fixture manufacturing errors, it is difficult to stabilize the product. The two holes are coaxially required to be processed. Aluminum profile machining precision parts.
In order to meet the design requirements of various aluminum profile processing products, stabilize product quality control, CNC lathe processing, the process design adopts the automatic tool change function of CNC lathes, and the inner hole back boring tool is used to process φ50mm holes from the surface, and φ128mm and φ50mm are arranged in the same process. process is completed. Avoid the influence of repeated positioning errors and fixture manufacturing errors on machining accuracy, and ensure the coaxiality requirement of φ0.03mm for aluminum profile processed products.
Since the diameter of the hole is φ48mm, the maximum machining diameter is φ100mm, the cutting width is 26mm, and the strength of the special arbor is 20mm for finishing strength. The aluminum profile processing technology scheme makes full use of the characteristics of the product structure and the flexible control of CNC equipment operation, which can not only reduce the work process, save equipment and processing costs, but also be stable and ensure the quality of aluminum profile processing parts.
Axial positioning supports for the workpiece can be adjusted or 'from the cart' to ensure a 'coplanar' position. However, in the traditional three-jaw chuck structure, the movement of the jaws in the jaw seat will inevitably have a certain sliding gap. During the clamping process, it will inevitably happen.
