The earliest metalworking examples are from South Asia between 7000 and 3300 BCE. Back then, artisans used crude tools and machinery to craft everything from cargo ships to jewelry. Today, metalworking machines are much more complex and sophisticated, which is why modern machinists can handle intricate orders for major industries with much more accuracy and speed.
Metallurgy is a high-tech process that involves working with various metals to create precision parts for small or large-scale projects. It’s what countless architects, product developers, and engineers use to produce the components required for their ideas. Therefore, CNC machine shops must combine the right skills, processes, machines, and tools to provide consistent service.
All of that requires a talented staff and top-notch metalworking machinery, which means competitive machining facilities should do more than just cover the bases. In the meantime, partners, vendors, and clients should understand the fundamentals of metalworking machines so they can enjoy more efficient outcomes and lower manufacturing costs.
What are the fundamentals of a metalworking machine?
Metalworking machines are generally complex and heavy-duty, with a wide range of compatible accessories to help create the ideal component. Metal machining tools are commonly classified into three main categories too:
1. The workholding
2. The metalworking fluids
3. The power tools
1. Metal Cutting
2. Metal Forming
Generally, metal cutters utilize drills, broaching machines, gear cutters, and electrical-discharge rigs or complete machining centers to produce fast, accurate outcomes. Other elements may include grinders, milling or turning machines, and transfer systems to accommodate complex orders. Either way, most metal machining processes consist of the same three stages.
What are the three stages of metal machining?
Briefly, let’s go over the three main stages of metal machining so you can better understand how and why certain machines and tools are used:
This step involves using a variety of tools and machines to cut, bend, shape, and assemble the metal workpiece into the desired form. It’s a vital stage because it allows machinists to produce working prototypes that can be examined and tweaked for mistakes.
Professional metalworking typically consists of these complex fabrication methods as well, which ultimately involve their own specific tools, fluids, and designs:

Which machines are used in CNC metalworking the most?
The modern metal machining industry uses a wide variety of techniques to create products and improve upon existing ones. However, the following are the 7 most commonly used machines today:
Lathe machines rotate a workpiece at high speeds and are used for a wide variety of different machining operations, including precision metal cutting, surface finishing, knurling, boring, and threading. They come in many sizes for a range of capabilities.
Shaper machines use a single-point cutting tool to create the desired product shape through repetitive linear motions. It’s a relatively simple rig so it’s ideal for smaller projects. However, shapers are also great for mass production because they can work at great speeds.
Broaching machines utilize a toothed tool (broach) to remove layers of material from the surface of a workpiece. They’re either linear or rotary depending on the required operation. Plus, they can even be used for certain small-scale projects in the right hands.
Saw machines are either hacksaws, circular saws, or band saws. They’re used to cut a piece of metal into several separate parts. Meanwhile, these machines use a sharp, rotating or reciprocating blade to get that job done faster.
Planer machines keep the cutting tool stationary while the metal workpiece moves in a linear pattern. It’s a lot like a shaper machine in that way, except planers are generally larger than shapers which means they can handle mass production more efficiently.
Shearing machines cut sheet metal without forming chips or residual materials. Similar to blanking and piercing, this process is one of the most eco-friendly options for contemporary project managers because of its innate reduction of waste.
Hobbing machines make metal splines and gears. They’re a type of milling rig that utilizes special cutting tools for custom projects. However, they’re most commonly used to create spur gears although operating one is relatively inexpensive.
NOTE: CNC machinists must possess a deep understanding of material properties to produce precision metal parts because some materials can react negatively when exposed to certain fluids, cutting tools, or production methods.
Making the most of metalwork
Precision manufacturing requires more than just space, time, and skill. Competitive CNC shops must also have the right metalworking machines and tools to complete jobs ahead of schedule. So, team up with a crew that understands material properties and knows how to operate the best rigs for each project.
