In the field of precision equipment in the knitting industry, the direct selection single system milling needle plate computerized flat knitting machine has attracted much attention for its efficient and stable performance. The core of this equipment's ability to knit accurately depends largely on the manufacturing process of the direct milling needle plate. From an ordinary steel blank to a key component that can ensure smooth movement of knitting needles and accurate knitting, what kind of transformation has the direct milling needle plate undergone? How does it provide a solid guarantee for the knitting accuracy and efficiency of computerized flat knitting machines?
The production of the direct milling needle plate starts with the material selection and molding stage. The choice of steel plays a decisive role in the performance of the needle plate. What kind of steel is suitable for making direct milling needle plates? Those with good comprehensive mechanical properties and able to withstand long-term and frequent friction of knitting needles are the first choice. After selecting the steel blank, the first task is to process it into the approximate shape of the needle plate. This process is like a sculptor facing a piece of raw stone, and first trimming it to the basic outline of the work. The processing method should be determined according to the characteristics of the steel and the design requirements of the needle plate. Whether it is cutting or forging, there is only one purpose, which is to lay the foundation for subsequent processing and make the steel initially have the shape of the needle plate.
After completing the material selection and forming, the straight milling needle plate enters the rough processing stage. At this stage, the focus is on the preliminary milling of basic structures such as the needle groove. The needle groove is the track for the movement of the knitting needle, and its initial shape processing is crucial. During the processing, the operator must use professional processing equipment based on precise design drawings to determine the approximate shape and position of the needle groove. The depth and width of each milling need to be strictly controlled. Any slight deviation may affect the subsequent movement of the knitting needle in the needle groove. This is like building a highway. The rough processing stage is to open up the prototype of the road first. Although it has not yet reached the final fine standard, each step of the operation is close to the high-quality finished needle plate.
After the rough processing is completed, the straight milling needle plate ushered in the most critical finishing stage. At this stage, the dimensional accuracy and surface roughness of the needle groove are strictly controlled. The core goal is to ensure that the bottom surface of the needle groove is flat so that the knitting needle can move up and down smoothly in the needle groove. In terms of dimensional accuracy, the width and depth of the needle groove must be perfectly matched with the knitting needle. If the needle groove is too wide, the knitting needle may shake during movement, resulting in defects in the knitted fabric; if the needle groove is too narrow, the knitting needle cannot pass smoothly, and may even damage the needle plate and the knitting needle. The surface roughness should not be ignored either. The rough surface of the needle groove will increase the resistance of the knitting needle movement, which will not only affect the knitting efficiency, but also accelerate the wear of the knitting needle and the needle plate. Therefore, in the finishing process, high-precision processing equipment and fine processing technology are used, and through multiple grinding, polishing and other operations, the needle groove surface can achieve extremely high finish.
So, how does this fine manufacturing process of the direct milling needle plate affect the knitting accuracy and efficiency of the direct selection single system milling needle plate computer flat knitting machine? First of all, the precise needle groove size ensures the stability of the knitting needle during movement. When the knitting needle moves up and down in the precisely sized needle groove, it can accurately complete each knitting action according to the design requirements, whether it is looping, tucking or floating thread knitting processes, it can be accurately presented. This means that the computer flat knitting machine can weave a variety of complex and delicate patterns, from simple striped patterns to exquisite jacquard patterns, which can be perfectly realized, greatly improving the quality and beauty of the fabric.
Secondly, the flatness of the bottom of the needle groove and the good surface roughness greatly reduce the resistance of the knitting needle movement. The knitting needle moves more smoothly in the needle groove, and the head of the computer flat knitting machine does not need to overcome too much resistance during the back and forth knitting process, and the operation is lighter and more flexible. This not only increases the knitting speed, but also reduces the energy consumption of the equipment. At the same time, due to the reduced wear between the knitting needle and the needle plate, the service life of the equipment is also extended, and the company does not need to frequently replace parts, reducing maintenance costs.
The entire production process of the straight milling needle plate from material selection and molding to fine processing, each link is closely connected and linked. Problems in any link may cause the final needle plate to fail to meet the use requirements of the computer flat knitting machine. Poor material selection may make the needle plate non-wear-resistant and affect its service life; inaccurate needle groove position during rough processing will cause disordered needle movement in the subsequent knitting; and substandard finishing will not guarantee knitting accuracy and efficiency. Therefore, only by strictly controlling every production link can high-quality direct milling needle plates be produced, providing reliable support for the stable operation and efficient production of direct selection single system milling needle plate computerized flat knitting machine.
