Are you a metalworking enthusiast? Are you interested in intricate artwork or logos made of metal? So, welcome to the variety of applications in this industry, from metal marking, engraving, stamping and etching to grinding and milling, and we will show you the unique charm of different machining processes.
Metalworking is the production activity in which various processes are applied to metallic materials to create the required parts, line components or overall large structures. From many large-scale projects such as oil rigs, ships, bridges to small parts such as engines, to jewelry, etc. are manufactured by metal processing. Therefore, it is necessary to use a wide range of techniques, processes, tools to deal with metals and finally obtain the desired results.
The process of metal processing is roughly divided into three categories, namely metal forming, metal cutting and metal joining. In this article, we will focus on the latest technologies applied to metal cutting.
Cutting is the process of bringing material to a specified form by removing material using various tools. Its finished parts shall meet specified requirements in terms of size, workmanship, design and aesthetics. There are only two products of cutting - scrap and finished product. After the metal is machined, the scrap is called metal swarf.
The cutting process can be further divided into three categories:
——The chips that generate chips are divided into one category, also known as machining.
- Classify materials that are burned, oxidized or evaporated into one category.
- A mixture of the two, or other processes are classified into one category, such as chemical cutting.
Drilling holes in metal parts is the most common example of a Type 1 (chip generating) process. Using a torch to cut steel into small pieces is an example of the combustion category. Chemical grinding is an example of a special process that uses etching chemicals, etc., to remove excess material.
Cutting Technology
There are many techniques for cutting metals, such as:
- Manual techniques: such as sawing, chiseling, shearing.
- Mechanical technology: such as punching, grinding and milling.
- Welding/combustion techniques: e.g. by laser, oxy-fuel combustion and plasma combustion.
- Erosion technology: machining using water jet, electrical discharge or abrasive flow.
- Chemical technology: photochemical processing or etching.
As you can see, there are many different types of metal cutting methods, and knowing and mastering these is a good place to start, allowing you to take advantage of all the techniques available to navigate this wonderful field.
