Inspection is an important step in the maintenance of machine parts in the mechanical industry. What items need to be checked and how to inspect them? Inspection Items of Mechanical Components During the quality inspection and maintenance of the machine parts, a lot of characteristics need to be inspected and verified. 1) Geometric accuracy Geometric accuracy includes dimensional accuracy and shape and position accuracy, but sometimes the maintenance work is not to pursue the geometric size of a single part but to require relative fitting accuracy, which is often an important p......

Dimensional accuracy refers to the accuracy of the dimensions of a specified part, such as the length, diameter, thickness, and keyway width of the workpiece. This dimensional accuracy is important for the part to be integrated into the machine and operate properly. If the dimensions are incorrect, it can cause the machine to fail. To prevent this, tolerances must be indicated in the drawing so that the dimensional accuracy of the critical parts is available when designing the part. For example, when designing a bearing with an outer diameter of Φ25 axis, it is necessary to indic......

The environmental audit is the activity carried out, periodically, by an organization to evaluate the performance of its management for the care of the environment and, in the case of being obliged to comply with a standard, a law or a standard, verify compliance with those requirements. Other activities, with similar purposes and which are also very important for the success of management such as inspections and reviews, are often confused or taken as an environmental audit, without being so. The differences between them go beyond the semantic. In the case of the audit, for e......

Starting to work with foreign suppliers in general is a real challenge. In particular for a new importer! Language and cultural barriers, and lack of experience can discourage and slow down projects. However, with these simple steps and the help of an expert, efficient supplier selection in Asia becomes easier: Supplier Search Determine the needs to be able to filter several elements such as: – The activity of the supplier (manufacturer, marketer).– The characteristics of the product (shapes, sizes, colors, weights, dimensions, possibility of customizing with a logo for exa......

Our daily lives are full of rubber products. Rubber soles of shoes, belts, hoses, tubes, tires, to name a few. There are various processing processes before they are distributed as rubber products. In this article, we will focus on how to process rubber and examples of defects that can occur during manufacturing. We have summarized the basic matters so that it is easy to understand even for those who do not have basic knowledge about rubber processing. If you want to acquire knowledge about rubber processing, please read to the end. What Is Rubber Processing? As the name su......

The expression “burrs” that is commonly used in metal processing sites such as pressing and cutting may not be understood by people who are not involved. Therefore, on this page, we will explain what burr is and why it occurs. We will also introduce the challenges of measuring burr as a quality inspection and how to solve them. What Is Burr? Burr is a metal ledge that occurs on the cut surface in shearing and drilling by pressing. It is also commonly defined as “the outer residue of a geometric shape at the edge of the shape and the residue on the part during......

Quality Inspection is an important process to ensure quality by evaluating whether the products of manufactured parts and products conform to the specified values. In particular, inspections of appearance, dimensions, and shape can not only prevent the outflow of defective products by determining whether OK or NG is possible but are also useful for identifying the cause and preventing recurrence by obtaining detailed information on defects and defects and conditions. In addition, in the case of products consisting of multiple parts, it is possible to prevent the outflow of defect......

Gears, along with screws and springs, are parts used in many products. There is a wide variety of sizes, shapes, and materials depending on the application. In addition, there are various functions, and it can be used for various purposes by combining gears and gears, as well as shafts and cams. And all gears are made with high precision. However, with increased use, for example, deformation due to wear occurs. Among them, the dimension of “tooth thickness” is important, and it greatly affects not only the operation of the gear but also the strength. Here, the conc......
