Table of Contents Introduction Definition and Importance Sheet metal bending is a core manufacturing process in which flat metal sheets are transformed into three-dimensional shapes through controlled plastic deformation. Using tools such as press brakes and dies, materials are bent along straight axes to achieve functional, often highly precise geometries.
With the development of society, aircraft, aerospace vehicles, drones are increasing, the demand for thin-walled parts is increasing. Thin-walled parts internal hollowing, high excision rate is generally more than 90%. Thin-walled parts require high-precision milling with heavy metal removal, but low rigidity and easy deformation reduce milling efficiency. Milling thin-walled
In the processing of metal materials, heat treatment technology is widely used. The technology through heating, holding and cooling steps, change the internal organization of metal materials, and then improve their mechanical properties and stability. However, the deformation and cracking problems generated in the heat treatment process have always been
Introduction to Machinability Machinability is a fundamental property in manufacturing engineering, reflecting the ease with which a material can be machined to meet dimensional tolerances, surface finish specifications, and production efficiency targets. A material with good machinability allows for faster cutting speeds, reduced tool wear, lower energy consumption, and consistent
Introduction In precision manufacturing and engineering design, the details of how components are joined or mounted are critical. One such feature that plays a significant role in these assemblies is the blind hole. What Is a Blind Hole? A blind hole is a hole that is drilled or machined into
In today’s precision-driven manufacturing landscape, where tolerances are tighter and component performance often hinges on microscopic variances, reamers play a crucial but sometimes underappreciated role. These multi-edge rotary cutting tools are engineered not to create holes, but to perfect them—delivering dimensional accuracy, fine surface finishes, and geometric precision that other
Introduction Aluminum alloys are foundational materials in modern engineering, prized for their combination of low density, high strength-to-weight ratios, corrosion resistance, and versatile machinability. Among the myriad of available aluminum alloys, 6061 and 7075 are two of the most widely used in structural and mechanical applications. Choosing between these alloys
