  • 3. Open-air drilling rig: according to the different working mechanism of crushing ore and rock, it is divided into steel rope percussion drill, drilling rig, cone drill and rotary drill. Because of low efficiency, the steel rope percussion drill has been gradually replaced by other drilling RIGS. The drill pipe drives the pneumatic impactor and the drill bit to rotate together, and the piston of the pneumatic impactor is used to impact the drill bit to break the ore and rock, which is usually used in small and medium-sized mines to drill holes with a diameter of 80 to 250 mm. The roller drill uses the rolling action of the roller bit to break the rock and is suitable for drilling holes of 150 ~ 440 mm in diameter on the hard rock. It has the advantages of high efficiency and low labor intensity, and is widely used in large and medium-sized open-pit metal mines. The drill consists of an impactor (or drill bit), a rotary mechanism, a lifting mechanism, a pressure device, a walking mechanism, a slag discharge system, a drill frame and a drill pipe. Rotary drilling machines are only suitable for drilling softer minerals and coal. The common feature of these devices is that the degree of automation is getting higher and higher, and some functions realize the application of intelligent i GPS technology on these RIGS, which realizes the automatic positioning of the boom, saves the time of field marking and positioning, improves the efficiency of the operation, and enables the operator to concentrate on monitoring the process of drilling. At the same time, more attention is paid to safety and environmental protection and the improvement of human-machine relationship. With the impact of the implementation of engine emission regulations, mobility, intelligent handling and environmental regulations Tier 3/ Euro ⅢA emission regulations, most foreign rig manufacturing companies have adopted diesel engines that meet the emission standards

  • Moreover, investing in a coverstitch machine can significantly enhance one's sewing capabilities and open doors to new projects. As sewists become more familiar with the technique, they can explore the endless possibilities of garment design, incorporating coverstitch into their repertoire.


  • One of the main advantages of a universal walking foot sewing machine is its ability to sew through multiple layers of fabric with ease. The walking foot mechanism ensures that the layers of fabric are fed evenly through the machine, preventing uneven stitching and puckering. This makes it ideal for quilting, upholstery, and other projects that require sewing through thick materials.
  • As you sew, keep a consistent distance from the edges of the leather. A standard distance is about 1/8 inch to 1/4 inch, depending on the project requirements. Using a ruler or spacing tool can aid in achieving uniformity, especially for larger projects. Moreover, always keep the needle perpendicular to the leather to prevent it from slipping, which can lead to uneven stitches or damage.


  • When selecting a commercial zig zag sewing machine, various features should be considered to ensure it meets specific needs. Some essential features include


  • One of the key features of commercial sewing machine needles is their sharpness and precision. This allows them to penetrate through tough fabrics and materials with ease, creating clean and even stitches. The sharp point of the needle enables it to pierce through multiple layers of fabric without breaking or bending, making it ideal for sewing thick materials like denim, canvas, and leather.
  • In conclusion, automatic template sewing machines represent a significant advancement in the textile industry, combining efficiency, accuracy, and creativity. As these machines continue to evolve, they promise to play an increasingly vital role in shaping the future of sewing, both for industrial applications and personal projects. Whether you are a seasoned professional or a novice at the sewing machine, embracing this technology may unlock new possibilities and enhance your sewing experience. As the industry continues to innovate, the potential for even more sophisticated automatic template sewing machines awaits on the horizon, heralding a new era in textile production.


  • One of the standout features of handheld leather sewing machines is their portability. Whether you're crafting in your living room, working on a project at a friend's house, or even taking your materials to a workshop, these machines are easy to transport. Their mobile nature encourages creativity on the go, allowing crafters to seize inspiration wherever they find it.

  • However, the adoption of CNC sewing machines doesn't mean the demise of traditional skills. On the contrary, it augments the skills of skilled artisans. They can focus more on design and quality control, leaving the repetitive and labor-intensive tasks to the machine. This blend of technology and craftsmanship results in a harmonious balance between efficiency and artistic expression.
  • Incorporating a twin needle into your sewing routine can elevate your project designs dramatically. By using different colors of thread for each needle, you can create stunning decorative effects. This technique is especially popular in quilting, embroidery, and crafts, where adding a splash of color can bring an otherwise simple project to life.


  • Chain stitch machines find extensive applications across various segments of the textile industry. For instance, they are widely used in the production of casual wear, activewear, and performance gear, where flexibility and durability are paramount. Additionally, they're employed in quilting processes, where intricate patterns are necessary, and in the sewing of decorative trims or hems, enhancing the garment’s aesthetic appeal.


  • This dual-feed system ensures that both layers of fabric move in synchronization, reducing the chances of puckering or shifting that can ruin a project. This is particularly beneficial when working with quilt layers, as a walking foot can help achieve even stitches without the hassle of basting or pinning the fabrics together.


  • 4. Adjustable Stitch Length Having the option to adjust stitch length is important when working on projects involving fur and leather. Thicker materials typically require longer stitch lengths to avoid perforating the leather and damaging the fur. A sewing machine that allows for easy adjustments will give you greater control over your projects.


  • 5. Additional Accessories and Maintenance Some manufacturers bundle their sewing machines with various accessories, such as extra needles, presser feet, and instructional manuals, which can impact the overall price.
