When you are using a fastener, thread pitch is a frequently used term, and it determines whether two parts properly fit each other. In this post, we want to concentrate on thread pitch, covering its definition, types, reading, measurement, as well as metric and American thread pitch chart. What I......

Runout tolerance is a crucial concept in geometric tolerancing used for controlling the variation in rotating parts during their operation. It ensures that CNC parts will run smoothly without wobbling or vibrating, which is essential for the reliability and precision of mechanical systems. This guide will explain the concept of runout tolerance, differentiate between circular runout and total runout, and provide usage guidelines. What is Runout Tolerance? Runout tolerance is a type of geometric tolerance that limits the amount of variation or “wobble” in a rotating ......

The humble flat washer is an ubiquitous yet often overlooked metal component used in countless mechanical assemblies. While simple in design, flat washers serve important functions that enhance the performance and longevity of bolted joints. Properly selected and installed, washers can stabilize bolt heads, distribute clamping loads evenly, prevent damage to mated parts, and act as lock washers to counter loosening. This guide provides an overview of flat washers, including their key purposes, common materials and finishes, standard sizing specifications, the variety of types available,......

Screws and bolts are used in all kinds of machinery, buildings, and structures. When joining parts with threaded portions, or when fixing a part to another part using bolts, torque is applied to rotate and tighten the parts or bolts. At this time, the force in the axial direction that prevents the separation of the parts and parts is called the “axial force”. In this way, to prevent loosening of the screws, it is important to properly manage the axial force when tightening the screws. The axial force pushes the parts together in the axial direction to prevent them from separ......

Two important geometric tolerances in GD&T are straightness and flatness. Both control the form of a surface or feature without relating it to other design elements. However, straightness and flatness apply to different geometric entities – straightness controls the linearity of edges or axes, while flatness controls the evenness of surfaces. Proper application and interpretation of straightness and flatness tolerances are critical to ensure manufactured parts fit and function as intended. In this blog, we discuss the key differences between these two GD&T controls......

The rapid development of the automotive, motorcycle, and machine tool industries has provided the driving force for the development of cold forging as a traditional technique. The demand for forged parts in the automotive industry alone exceeds 10 million tons. The development of cold forging technology is mainly to develop high value-added products and reduce production costs, and at the same time, it is also infiltrating or replacing cutting, powder metallurgy, casting, hot forging, and sheet metal forming processes. It can also form composite processes by combining with these process......

Aluminum is mass-produced and utilized across a broad spectrum of industrial, commercial, and residential applications. This metal is incredibly versatile, making it suitable for a seemingly endless array of purposes. However, its diversity and adaptability also mean that selecting the right aluminum alloy for your specific application can be challenging. Manufacturers, product developers, and other business entities must carefully plan and assess their objectives to choose the most suitable alloy option for their particular products, projects, systems, or applications. Two aluminum all......
