A Guide for Engineers：This engineer’s guide provides a comprehensive overview of CNC machining tolerances based on ISO 2768 standards, recommended tolerance ranges for common materials, and the impact of tolerance selection on manufacturing cost. It also showcases how Jeek Rapid achieves extreme tolerance control of ±0.02mm through advanced equipment and processes—with real-world cases demonstrating precision …
The Origin and Development of CNC Machining:CNC machining originated in the 1940s. In 1952, the Massachusetts Institute of Technology (MIT) in the United States developed the world’s first numerically controlled milling machine by integrating a computer with a machine tool, marking the birth of CNC technology. The core principle is using computer programming to control …
In today’s fast-evolving manufacturing landscape, CNC machining remains the preferred method for prototyping — and for good reason. Despite the advancements in 3D printing and other emerging technologies, CNC prototyping continues to hold an irreplaceable position in terms of precision, material flexibility, and cost-efficiency. These are the key reasons why CNC machining remains the best …
Development:Turning: Originated from ancient pottery wheels and woodworking lathes, turning evolved into a metal processing technique during the Industrial Revolution, laying the foundation for modern turning technology. By the 19th century, as lathes were gradually improved, turning became capable of stably processing cylindrical, conical workpieces and threads. It became one of the most fundamental …
Development:Before the 19th century, humans had already used metal powders to make ornaments such as gold and silver jewelry. A major breakthrough in powder metallurgy occurred in 1870, when a Russian scientist invented tungsten carbide (WC) powder, laying the foundation for hard alloys. In 1909, Coolidge in the United States invented the tungsten powder sintering …
In modern manufacturing, many precision components are too small or complex for traditional methods like CNC machining, stamping, or casting. Metal Injection Molding (MIM) fills this gap by combining the design flexibility of plastic injection molding with the material performance of powder metallurgy. It is especially suitable for high-volume production of intricate, high-precision metal parts.…
In this article about die casting, it’s worth noting that die casting typically involves high initial production costs. As a result, this process is most often used for mass production. Only large-scale production can offset the cost of die casting. Of course, small-batch production is also possible—but only if you provide us with the design …
5-axis machining is a high-precision CNC technology that controls five motion axes simultaneously to cut complex geometries. Compared with traditional 3-axis machining (X, Y, Z linear motion), a 5-axis system adds two rotary axes, allowing the tool to maintain an optimal cutting orientation. This reduces re-clamping, minimizes cumulative tolerance deviation, and improves both accuracy and …
