Pickling removes impurities from metal surfaces, such as scales, rust, and oxides. The metal is immersed in an acidic solution (usually hydrochloric acid or sulfuric acid), which dissolves the contaminants. The metal will be left with a smooth, clean surface, ready to undergo further processing such as painting or coating.
Electron Beam Welding is a process of joining materials using a high-speed electron beam. The process is carried out in a vacuum, which helps to prevent contamination and oxidation. The high-energy electron beam allows deep penetration welding with minimal heat input.
Automatism is the basis of CNC punching. A computer program controls the movement and actions of the punch press. The program is created based on specific project dimensions and patterns. The punch press follows these instructions to punch the holes or shapes in the sheet metal.
Finding the perfect material for your CNC machining project doesn’t have to be complicated. By understanding the specific needs of your project and matching them with the properties of various materials, you can ensure efficiency, quality, and cost-effectiveness. Let’s explore some popular CNC machining materials and their applications.
The electrochemical process removes a thin coating of metal from its surface. This results in a shiny, smooth finish. Mechanical polishing uses abrasive material to grind and buff metal, producing a similar result. Each method has pros and cons, which I will explore in depth.
Seal welds have been designed to create a leakproof seal. Seal welds seal gaps between metal components, ensuring no gases or fluids can escape. This technique involves creating an uninterrupted weld at the joint. The edges are often overlapped to ensure complete coverage.
Hot-dip galvanizing immerses steel in molten zinc, forming a thick (80–100µm) metallurgical bond ideal for harsh outdoor exposure. Electro-galvanizing electrically deposits a thin (10–12µm), uniform zinc layer, preserving tight machining tolerances and yielding a smooth finish strictly for indoor, low-corrosion environments.
Boring enlarges a hole that has already been created by drilling. A rotating drill bit is used to create a hole in the material. Boring uses a single-point cutting tool to extend an existing drilled or cast-in hole.
CNC machining tolerances are the allowable deviations from the specified dimensions of a part. They define the range within which the actual measurements of a part can vary while still being acceptable. Tolerances ensure that parts fit together correctly and function as intended, maintaining the quality and reliability of the final product.
