Are you a metal working enthusiast? Do you relish the prospect of creating intricate pieces of art, signs, or logos using metal? Are you in the industry and want to mark or simply work metal for various use cases?
Cutting produces two products, the waste, and the finished part. After cutting metal the waste is called metal chips, or excess metal. Cutting processes further fall into three major categories:
- Those which produce chips, also known as machining
- Those that burn, oxidize or vaporize material
Drilling a hole in a metal part is the most common example of a chip-producing process. Using an oxy-fuel cutting torch to separate a plate of steel into smaller pieces is an example of burning. Chemical milling is an example of a specialty process that removes excess material by the use of etching chemicals and masking chemicals.
- Manual technologies:e.g. sawing, chisel, shearing
- Machine technologies:e.g., stamping, grinding, and milling
- Welding/burning technologies:通过激光，氧气燃烧和等离子体燃烧
- Erosion technologies:by water jet, electric discharge, or abrasive flow machining.
- Chemical technologies:Photochemical machining or etching.
As can be seen, there are many types of cutting metal work, and collecting reading resources is a good start point to enable you to harness all the available technologies for a good grasp of this amazing field.

A look at some metalworking techniques
We cannot be able to cover all these technologies in one article. However, we will select six of these techniques and explain what they are, their respective tooling, and possible use cases.
Direct Part Marking(DPM) is a range of technologies that are used to create permanent markings on metal for the purposes of part traceability, labeling industrial pieces, ornamentation, or any other purpose.
Marking metal is as old as the invention of smelting techniques when man started using metal tools like axes and spears. However, current technologies have evolved to allow man for the first time to create high precision and intricate marking for all conceivable use cases. Marking is achieved through various techniques, including engraving, embossing, die casting, stamping, etching, and grinding.
Engraving is achieved through the use of two main technologies, which are laser and mechanical engraving.
Are you researching how to engrave metal? Do you want solutions for different applications you are interested in? A suitable laser metal engraving machine could be just what you are looking for.
Despite being very versatile and easy to use,激光technology gives you the highest quality in metal engraving because it is computer-aided, and its application is precisely predetermined on various surfaces for best results.
机械的雕刻可以手动完成，或通过更可靠地使用受电弓或计算机数控（CNC）机器。我们发现了这样的机器的集合Gravograph。It has many advantages including replicability and low operating costs.
However, it is pricey, as the equipment and computers used may come at a price of around $75k-$100k. Also, it is not as versatile as laser engraving, and die breakage or outage may mean losing a half-engraved piece.

Metal Stampingis not a subtractive process. It uses dies to fold flat metal sheets into shapes.
Mostly, household appliances like pans, spoons cooking pots, and plates are made using a combination of casting and cutting. There are mechanical and hydraulic metal stamping machines.
Metal sheets of up to ¼ inch made of stainless steel, aluminum, zinc, and copper are cast, punched, flanged, and cut by these machines into 3D objects. They have very high product turn-over rates due to the relative ease with which they carry out the casting and cutting.
The presses can be used in many applications because of the wide range of items they can produce. They come in different sizes and designs, and most are for industrial use.
Precious metal stamping machines also exist. There are many in this industry. In the US, for example, you could try Norstan in Wisconsin, Nesper in Georgia, orHPL Stampings Inc，来自伊利诺伊州。

Their products are used in as diverse industries like medical, electronic, electric, automotive, military, HVAC, pharmaceutical, commercial, and machine-build markets. There is much more information about these machines onThomasnet.com。
Etching can be achieved either through photochemical or laser processes.
Are you in search of the latest technologies in metal etching? Laser etching is what you need then.
This technology has evolved exponentially over time. It involves the process of creating high-precision designs by the use of coherent amplified light beams on a metal surface.
Laser is the cleanest mode of etching marking as it does not involve the use of corrosive reagents, bits, or noise-intensive abrasive processes. It is simply the laser beam vaporization of material to create exact images or texts as instructed through a computer program.
There are also emerging smaller and smaller equipment that can be used by researchers and enthusiasts for laser as the technological advancement allows for cheaper options.
The chemical enabled the process exposes parts of a metal piece to a strong acid (or mordant) to cut patterns on it and create a design in intaglio (or incised) in the metal. It is subtractive in nature, using etchant chemistry to produce complex, high precision metal components.
In a basic metal etching, the flat metal surface is covered with a special coating that is resistant to acid, and select parts of the coating are scratched away by hand or mechanical means. The metal is then placed in an acid reagent bath.
The acid erodes the part of metal not covered by the coating, leaving a pattern identical to the one scratched into the coating. The workpiece is then removed and cleaned, and inks can be used to print the pattern on paper, etc. Photoetching involves the photomechanical application of the acid-resistant layer on the metal surface.
There is a wide range of machines in this field. Some of the best laser etching machines can be found atHeatSign。They range from Fiber laser, CO2, and UV machines.
We mention them here because their website is very easy to navigate and they have a very fast customer service chat that gives relevant feedback immediately you start chatting. Other brands can also be accessed from Alibaba, Amazon, and eBay.
Etching can be used together with scanning to produce replicas of artifacts for restoration. This replication is also used to create costumes and movie sets. Etching is an important part of jewelry making and the gift industry.
Metal grinding is a physical abrasion using a cutting tool, commonly used to finish off rough edges, deburr, smooth welds, remove chips, create sharp edges or create unique finished looks to a metal part.
It is mostly the last bit of operation to a part that has undergone engraving, stamping, etching, or any other forms of metalwork. Interestingly, this bit of metalworking is extraneous but labor-intensive. It can be mitigated by the use of a proper choice of design, material, and in-process operations.
There are six main types of grinding machines with different types of applications.
- Belt Grinder: basically uses a motorized belt coated with abrasive material which is then used on a metal surface to achieve the desired finish.
- Bench Grinder: These are very cheap and handy tools. They mostly involve a bench fastened motorized grinding wheel which when rotating can sharpen farmyard tools, round metal cut edges, etc.
- 气缸磨床: this type of grinder works mostly with cylindrical, elliptical, or combinations of these two. It consists of a rotating grinding wheel and an object manipulation system that feeds the workpiece to the grinder. Some models have inbuilt cooling systems to keep the workpiece as close to normal temperature as possible for best results.
- SurfaceGrinder: These are the most commonly used grinders. Surface grinding is mostly a finishing operation. The grinders use a rotating abrasive wheel to smooth flat metal surfaces and give them a more refined look or a desired functional surface.
- Bit Grinder:These grinders are mostly used to sharpen various types of drill bits.
- Jig Grinder：这些机器用于完成夹具，模具和固定装置。它们的主要功能是用于钻衬套和磨针的研磨孔的工作。它们还可用于完成复杂的表面研磨，以完成在轧机上开始的工作。这些磨床使我们能够以非常高的精度和精度在各种工具中制作复杂的几何钻孔形状。
shearin铣削形状金属或其他材料g material off a metal surface to form the final shape. Milling machines consist of a milling cutter that rotates on a spindle axis and a worktable that can move in multiple directions with respect to the work surface.
The spindle usually moves vertically as the worktable moves along the X and Y axis to create intricate patterns as designed. Milling machines can be operated either manually or under computer numerical control (CNC).
They perform complex operations, including slot cutting, planning, drilling and threading, rabbeting, routing, etc. Two common types of mills are the horizontal mill and vertical mill.
Milling machines are mainly used for drilling, reaming, and tapping various metal parts. It is the primary operation used to make engine blocks, gear parts, threads, and male-female parts for metal joinery.
They are mostly used on flat surfaces, though they can also produce irregular surfaces. They can also be used to make drill bits, bore, cut gears, and produce slots. They also make grooved holes into which bolts can be fastened.
