Shot-blasting
Definition and Principle Shot-blasting is a mechanical surface treatment process that uses high-velocity abrasive media to clean, strengthen, or prepare materials. The core principle involves accelerating abrasive particles (e.g., steel shot, grit, glass beads, or ceramic granules) via centrifugal force or compressed air, propelling them against a workpiece’s surface. This impact removes contaminants (rust, scale, coatings), […]
Advantages and Limitations of CNC Machining
Advantages: precision and accuracy CNC machining has high precision, can achieve micron-level accuracy, suitable for precision parts processing, and the quality is stable when repeated production. The customized CNC production line can realize automatic continuous machining and automatic detection with less manual intervention, which is very suitable for the production of high-volume parts. Multi-axis linkage […]
Tempering in Heat Treatment: An Overview
Tempering is a critical heat treatment process used to improve the mechanical properties of hardened metals (typically steels) by reducing brittleness, relieving internal stresses, and enhancing toughness. It follows quenching, which hardens the material but leaves it overly brittle and prone to cracking. Below is a detailed breakdown of the tempering process: 1. Key Objectives of Tempering […]
Materials Used in CNC Machining
From hard steel to relatively soft plastics, CNC technology’s machining capabilities cover a wide range of common materials: 1. Aluminum alloy Such as 6061 and 7075, are commonly used materials, with a density of 2.7-2.8g/cm³, very light, only about 40% of steel. High strength, but poor fatigue resistance and high temperature resistance, usually used in […]
How Much Does a CNC Machine Cost?
The entry-level 3-axis machine tools usually cost between $50,000 to $150,000, while high-end models from big brands like DMG and MAZAK can go up to $200,000 to $400,000. 4-axis machine tools with basic features range from $100,000 to $300,000, and models that support 4-axis linkage can reach up to $300,000 to $700,000. The price range […]
Heat Treatment Process for Metal Components
Heat treatment is a controlled thermal process that alters the physical and mechanical properties of metal components to meet specific performance requirements. Key stages include: Pre-Cleaning Remove contaminants (oil, grease, oxides) using solvents, alkaline baths, or abrasive methods. Ensures uniform heating and prevents surface defects. Heating Components are heated to precise temperatures in furnaces (e.g., […]
How CNC Machining Works?
In this section, we will take you through the complete CNC machining process from drawings to products. Design The first step of CNC machining products is to use CAD (Computer Aided Design) software (SolidWorks, AutoCAD, CATIA, etc.) to design the 3D model of the part, define the shape and size. When designing, you need […]
Cleanliness Standards for Metal Parts: Key Considerations and Practices
Cleanliness standards for metal parts are critical in industries such as manufacturing, aerospace, automotive, medical devices, and electronics, where contaminants can compromise performance, durability, or safety. These standards define acceptable levels of residues, particles, or impurities on metal surfaces after processing. Below is an overview of key aspects: 1. Definition of Contaminants Contaminants requiring removal […]
What Makes Up a CNC Machine?
A CNC machine is composed of more than 1000 parts, which can be roughly divided into 5 systems. Next, we take the standard 3-axis vertical milling machine as an example to get a general idea of the composition of a CNC machine tool through these 5 systems. 1. CNC system The CNC system is the […]
Surface Roughness of Metal Components
Surface roughness refers to the microscopic irregularities and texture on the surface of a metal component. It is a critical parameter in manufacturing and engineering, as it directly impacts functionality, performance, and aesthetics. Below are key aspects of surface roughness for metal parts: 1. Definition and Measurement Surface Roughness: Quantified by deviations in the normal […]
