What is roundness for precision machinery? An explanation of the basics!

What is roundness for precision machinery? An explanation of the basics!

Videos helpful for the design and manufacturing of bearings!

In the precision machinery industry, particularly in the design and manufacturing of bearings, understanding roundness is crucial. The performance of bearings is greatly affected by their roundness; low roundness can lead to increased vibration and wear during rotation, as well as a decrease in lifespan. This video explains the basics of "roundness," which is a type of geometric tolerance. It covers the definition of roundness, how it is used in drawings, and points to consider when using it. By understanding roundness, you can contribute to improving the quality of bearings. 【Application Scenarios】 - Bearing design - Bearing manufacturing - Quality control 【Benefits of Implementation】 - Improved bearing quality - Increased product reliability - Cost reduction

[Proposal Example] Ultra-Precision Machining × Ultra-Precision Measurement

[Proposal Example] Ultra-Precision Machining × Ultra-Precision Measurement

Cleared the requirements on the first attempt! It's the technical skill that comes from having the "yardsticks" of the processor and the measurer aligned.

We will introduce a case study in "Ultra-precision machining × ultra-precision measurement." There were products that became difficult to process for 12 other companies in the same industry, but we cleared the requirements (dimensional tolerances, roundness, cylindricity) on the first attempt. Our technical capability is due to the alignment of the "measuring standards" between the machinist and the measurer. *For more details, please refer to the PDF document or feel free to contact us.

Explaining the Basics of Parallelism for Precision Machinery!

Explaining the Basics of Parallelism for Precision Machinery!

I will answer the question, 'What is parallelism?'

In the precision machinery industry, quality control is highly dependent on the accuracy of products. Parallelism is an essential factor in ensuring the precise assembly and operation of components, as even slight deviations can affect the overall performance of the product. A lack of understanding of parallelism can lead to the occurrence of defective products and a decline in product performance. This video explains the basics of "parallelism," a type of geometric tolerance. It covers the definition of parallelism, examples of its use, how it is represented in drawings, and points to consider when using it, so you can enhance your quality control. 【Application Scenarios】 - Quality control in the manufacturing process of precision machine parts - Understanding parallelism indications during the product design phase - Measuring parallelism in quality inspections 【Benefits of Introduction】 - Deepening understanding of parallelism and improving the accuracy of quality control - Reducing defective products and cutting costs - Enhancing product reliability
