    Did you know that the very first machining tool ever invented was the bow lathe? Back in 1200 B.C.E., artisans were using manual tools like that to do what automatic tools can do today. However, the basics of modern-day CNC machine tools have always remained the same.
    The only difference is the sophistication of the tools being used by well-equipped CNC machine shops. Throughout the years, machinists and engineers have worked together to create better tooling techniques and implements. As a result, the manufacturing industry has blown up over the last few decades and it doesn’t seem to be slowing down anytime soon.
    So, what are the basics of today’s best CNC machine tools, and why does it matter? Here’s what you need to know.

    What is a CNC machine tool?

    These tools are used in the various processes performed by legitimate machinists. They’re commonly utilized for cutting, carving, drilling, and milling on a wide variety of different materials. Back in the day, though, CNC tools were reserved primarily for large factory work. Today, they range in size, shape, and function to deliver precision results on highly complex projects.

    Furthermore, contemporary CNC tools are broken down into three separate groups as follows:

    • General Purpose
    • Single Purpose
    • Special Purpose

    After that, there are at least 10 distinct tool types to consider before the processing can begin:

    • Mills
    • Drills
    • Lathes
    • Turning Machines
    • Plasma Cutters
    • Grinders
    • Power Saws
    • Planers
    • Presses

    Keep in mind that there are many types of CNC machines, so the tools used may vary quite a bit from one venture to another. To get more information about the tooling techniques available for your project, talk to an expert at Pioneer Cuts.

    What are the 5 basic elements of CNC machine tools?

    To use a machine tool properly, machinists and engineers must understand the fundamental elements of each option. Their knowledge about innate tool properties can significantly impact the final price of services, plus it may affect project outcomes as well. This is especially true during the final stages of production or throughout expedited metal finishing, non-destructive testing (NDT), and rapid prototyping.

    Meanwhile, all CNC machining tools operate using the same 5 fundamental components as follows:

    #1. Workpiece Holding Device

    Something needs to secure the blank in place while the rest of the operation is set up or while the cutting processes are being completed. This is both a safety and accuracy issue.

    #2. Tool Holding Device

    The tools must be secured as well. That’s because loose-fitted cutting tools may render inaccurate results and cost both the machine shop and the client more money.

    #3. Tool Motion Mechanism

    There needs to be a reliable system to drive steady, controllable motions from the cutting tool to the workpiece. But none of that is possible without a functional motion mechanism in play.

    #4. Workpiece Motion Mechanism

    For some projects, the workpiece itself needs to move in order for intricate geometries to be achieved. Thus, a similar motion mechanism is required to help cut costs and reduce errors.

    #5. Project Support Structure

    Everything in a CNC machine shop works in tandem, from the software to the tools to the machines. So, each project requires a support structure to anchor the components and produce perfection.

    Machine shops that don’t utilize all five of these components are either incapable of serving large industries or unable to create highly precise products in record time. Thus, only facilities with both the capacity for sophisticated tools and the expertise to use them can compete in today’s manufacturing market.

    How to choose the right CNC machine tool

    Choosing the right CNC machine tools can be tricky, especially if you’re not a professional machinist, programmer, or product engineer. There are many different things for them to consider before choosing the best tool. Here’s how you can help them out:

    1. Think about your materials. The types of materials you use for any manufacturing project impact the final outcome. Plus, the materials might also dictate which tools you can and cannot use.

    2. Look at your design. Certain elements of your product concept may require specific tools or techniques to complete. But if the materials and tools don’t line up, your project may be virtually impossible to finish.

    3. Consider the purpose of your product. Whether it’s meant to be observed or used, it’s important that the properties match their intended use. In some cases, that may require special tools, machines, materials, and processes.

    4. Make a prototype of your project. That way, you can discover and troubleshoot any unproductive or expensive elements – all without having to pay for or schedule full-scale production.

    5. Talk to a CNC tooling expert. They’ll know which tools and materials to use for every project and can help you uncover money-saving options and suggest product perfection techniques to help you thrive in your industry.
    Understand that contemporary CNC machining services are extremely complex and that’s usually why they’re so expensive. But gone are the days of simple bow lathes and hand drills. Today, you can do almost anything as long as you have the right tools and a dedicated manufacturing team.

    How to get your project started

    Start any manufacturing project by seeking more information from the pros. Ask for a quick cost estimate if you can, and then work with the engineering crew to choose the right tools for the job. Be sure to include any data that might affect project outcomes, including any potential flexibilities or rigid regulations. Also, find out if the machine shop that you’re working with is properly registered and/or certified to complete work for your industry.
