CNC cutting machines have revolutionized the way materials like leather are processed. Whether you work in the fashion industry, automotive interiors, or custom leather goods, CNC machines offer precision and efficiency that manual cutting can’t match. In this guide, we’ll cover everything you need to know about CNC cutting leather, from machine setup to material handling.
1. Why Use a CNC Machine to Cut Leather?
2. Choose the Right CNC Machine for Leather

4. Finishing techniques after CNC machine cutting
CNC machines offer a variety of advantages when it comes to cutting leather, making them the preferred choice for many professionals and hobbyists alike.
Precision and Accuracy: CNC machines are known for their ability to cut intricate patterns with incredible precision. Whether you’re creating custom shapes for bags, purses, shoes, or automotive interiors, CNC machines can replicate designs exactly without variation.
Consistency of Production: One of the most important advantages of using a CNC machine to cut leather is the consistency of the output. Once a design is programmed into the machine, it can be repeated as many times as needed and achieve the same results. This is essential for large-scale production where consistency is required.
Efficient Use of Materials: CNC machines optimize material usage by nesting multiple patterns within a single piece of leather. This reduces waste, maximizes efficiency, and ensures cost-effectiveness, especially when working with expensive leather materials.
These benefits make CNC machines a valuable tool for leather processing, providing speed and precision that is difficult to achieve with traditional methods.
Not all CNC machines are designed to cut leather, so it is important to choose the right type for your project. Here are the main factors to consider when choosing a CNC machine for leather cutting:
Laser CNC vs. Blade CNC: Two main types of CNC machines are commonly used for leather cutting - laser CNC and blade CNC.
Laser CNC machines use a focused beam to cut leather. They are great for detailed and intricate designs, but can sometimes produce slightly burnt edges due to the heat.
Blade CNC machines use a sharp cutting tool to physically cut the leather. These machines are great for thicker or harder leathers that require precision without the risk of burning.
Machine Size and Bed Area: Depending on the size of your project, you may need a CNC machine with a larger cutting bed to accommodate whole hides or large pieces of leather. Small desktop machines can be used by hobbyists working on small projects, but industrial machines offer more flexibility for larger productions.
Software compatibility: The software of the machine is just as important as the hardware. Look for a CNC machine that is compatible with popular design software such as AutoCAD, Adobe Illustrator, or specialized leather design software. This will allow you to easily import and manipulate the designs you want to cut.
Choosing the right machine depends on your specific needs, such as the size of the project and the level of precision required.
Before you cut leather with a CNC machine, there are some necessary preparation steps to ensure clean and accurate cuts.
Leather Type and Thickness: The type and thickness of the leather can affect the cutting process. CNC machines can handle a variety of leather types, including:
Full-grain leather: The most durable and highest quality leather. It requires precise tool setup, especially when it is thicker.
Top-grain leather: Top-grain leather is slightly thinner and easier to cut than full-grain leather, but still requires careful setup.
Suede: A softer, more flexible material that may require extra care to avoid stretching or tearing during the cutting process.
Faux leather: An increasingly popular synthetic alternative that cuts similarly to thinner leather, but with less attention to grain.
Flattening the material: Leather is a flexible material that may bend or curl. Before cutting, make sure the leather is lying flat on the machine bed. Some CNC machines use a vacuum bed or adhesive sheets to hold the leather in place during the cutting process. Properly securing the leather guarantees accurate cuts and ensures a smooth cut.
Testing settings: Before running a full design, it is best to test the cutting settings on a scrap piece of leather. Adjust the speed, pressure (for blade CNCs), or power (for laser CNCs) based on the material type and thickness to achieve a clean cut without damaging the leather.
Proper preparation is key to ensuring the cutting process goes smoothly and that the integrity of the leather is maintained throughout.
After the leather is cut, some finishing steps may be required depending on the type of project and the cutting method used.
Edge polishing: For blade-cut leather, you may need to polish or smooth the edges, especially if the cut is thick or rough. Edge polishing tools or manual techniques such as sanding can help improve the final product.
Burnt Edges from Laser Cutting: When using a laser CNC machine, you may see a slightly burnt edge on your leather. While some designers prefer this effect for aesthetic reasons, others may need to remove it by lightly sanding or buffing the edge.
Stitched Holes: For leather pieces that require sewing, CNC machines can also be programmed to create stitched holes during the cutting process. This ensures that the holes for hand or machine stitching are evenly spaced and perfectly aligned, reducing the time spent on manual preparation.
Leather Treatment and Conditioning: After cutting, it is important to condition the leather to maintain its quality. Applying leather conditioner or oil can keep the material supple and prevent it from drying out or cracking over time.
By incorporating these finishing techniques into your workflow, you can improve the quality of your CNC cut leather products and ensure they are ready for assembly or sale.
CNC machine cutting has become an invaluable tool in the leather industry, offering precision, efficiency, and consistency that manual methods cannot match. By choosing the right machine, properly preparing the leather, and applying finishing techniques, you can realize the full potential of CNC technology in your leather finishing projects. Whether you are an amateur or a professional, understanding these key factors will ensure that your CNC machine cut leather project is of the highest quality.
