The difficulty of aluminum processing that is hard to see from just the drawings.

The difficulty of aluminum processing that is hard to see from just the drawings.

For more details, please visit our website: https://www.toyoharahamono.com/

Aluminum processing is often thought of as "just cutting according to the drawings," but in actual processing environments, there are challenges that are difficult to understand from the drawings alone, such as thin walls, long lengths, appearance quality, and warping. This is especially true for parts used in semiconductor manufacturing equipment, where not only dimensions but also appearance and assembly characteristics are often required. In thin-walled processing, warping or deformation can occur after machining due to clamping and cutting influences. For long materials, in addition to deformation caused by their own weight and material characteristics, careful attention is also needed during storage and transportation. Moreover, for products with strict appearance quality requirements, even small scratches or dents can render the product unacceptable, necessitating meticulous care not only in processing but also in handling. Therefore, in the processing environment, we devise the order of operations, clamping methods, and cutting conditions to minimize warping and deformation while considering the processing methods. We may also review materials and processes as needed, taking into account the state during subsequent processes and assembly. Even parts that appear simple on the drawings can have significantly different finishes depending on the materials and processing methods used. At Toyohara Blade, we not only process according to the drawings but also engage in manufacturing while considering the entire process to ensure stable quality after completion.

The story of the processing site and the "partner."

The story of the processing site and the "partner."

For more details, please visit our website: https://www.toyoharahamono.com/

In cutting processing, there are times when jigs are made before creating a product. Jigs are not delivered to customers, nor do they appear on the drawings. Nevertheless, they are an indispensable presence in the processing site. We first combine existing jigs and off-the-shelf products, change their orientations, and devise processing methods while envisioning the final form. When we can process without creating a dedicated jig, it feels like we have been particularly resourceful. In contract processing, we often work based on customer drawings, so there are not many opportunities to design from scratch. One of the few exceptions is dedicated jigs. It is a moment when the processing shop becomes a designer, as we consider how to secure the jig for precision and how to process it to reach completion. A good jig does not confuse the next user. Its orientation and fixing position are intuitively understood, it is easy to attach and detach, and it is resistant to damage. By looking at the jig, the steps to complete the product are naturally conveyed. Jigs embody the ingenuity, experience, and thought processes of their creators. While they may not be visible, they are an important presence that continues to support until the product is completed. We dedicate the same amount of time and attention to the jigs that support the products, not just to the products themselves.

Dimension proposal considering the accuracy after assembly.

Dimension proposal considering the accuracy after assembly.

Precision leads to smooth assembly.

Have you ever experienced that even though you arranged individual parts according to the drawings, the required precision was not achieved after assembly? Even if the parts are precise individually, the product dimensions can be corrected during assembly, leading to deviations from the required precision. At our company, we leverage our experience in parts manufacturing within the assembly department to propose solutions that balance assembly efficiency and post-assembly precision, after confirming the part shapes and assembly methods. Please let us know your current challenges.

[Examples of Production by Purpose] High Toughness Rotating Shaft

[Examples of Production by Purpose] High Toughness Rotating Shaft

The material used is SCM435! The key point is how to hold the workpiece on the cylindrical grinding machine without any runout.

This product is used as the spindle for grinding wheels in grinding machines, requiring a dimensional accuracy of 0.005 or less for the cylindrical outer diameter and a coaxiality of 0.01 or less. Additionally, the flange part, which serves as the mounting reference surface, and the cylindrical surface require a perpendicularity accuracy of 0.005, necessitating finishing by cylindrical grinding for both the flange reference surface and the outer diameter. To achieve high precision finishing through cylindrical grinding, the key point is how to hold the workpiece without any runout on the cylindrical grinding machine. In this case, high-precision center holes are machined on both end faces, and the workpiece is held using a tailstock for high-precision machining. Furthermore, to ensure such precision machining, we have introduced roundness measuring instruments and are also working on guaranteeing geometric tolerances reliably. 【Production Example】 ■Material: SCM435 ■Product Size: φ86×L180 *For more details, please refer to the PDF document or feel free to contact us.
