Any machine is assembled from countless parts. To a certain extent, the stability of a sewing machine depends on the precision of the assembled parts.

Chongqing zero one Precision Machinery Co., Ltd. (hereinafter referred to as zero one) has researched and developed sewing machine parts for many years, especially shaft parts of transmission. Only by solving the production of key parts can the enterprise have core competitiveness. Miao Xianzhi, general manager of sewing business department of Saier media, and his party communicated with Guo zongzong and Fu Zong of zero one, and discussed in detail the importance of shaft products to sewing machinery.

In the past, the key supporting parts of sewing machinery involving high technology and high added value were mainly imported, but now the sustained and sound development of sewing machinery in China has brought a huge market to the spare parts industry. Zero one produces axle products with concentration and expertise. "Unlike other products, shaft parts can be operated on the assembly line. Because of their many varieties and specifications, most orders are in small batches."—— President Guo said when explaining the division standard of production workshops.

Minor defects of parts will bring problems and troubles to mechanical production, and precision machined parts can overcome these defects. When introducing the precision machining of shaft tools, President Guo said that each shaft tool will have cylindrical surface, conical surface, groove, thread and other structural characteristics according to the different transmission rotational motion and torque. Zero one will also heat treat shaft parts according to different needs of customers, aiming to improve the surface hardness of shaft parts without affecting the internal structure. In the production of zero one, special attention will be paid to the size, shape, position accuracy and surface quality of shaft products. They also have strict detection technology, which can ensure that the structural design of the finished products is reasonable and has sufficient rigidity.

"But these are only the basic requirements of the part. The most important thing is its durability." President Guo took the polished shaft tools and explained them to us one by one. The most important thing of the shaft tool is that it can adapt to the machine in terms of dimensional accuracy, shape accuracy and contact accuracy after assembly, and support the machine with sufficient wear resistance, vibration resistance, dimensional stability and fatigue resistance during operation. Zero one carefully polished its products in this regard, and was strict with itself. It was its responsibility to produce various specifications of shaft parts required by customers.

Production should maximize efficiency. Shaft products are produced in small batches and in multiple specifications. In order to adapt to this production mode, zero one does not use all automatic production lines, but uses unit automation mode. President Guo explained that zero one has a set of self-improvement production management system, which is no less than automated production. Among them, all the production links are arranged at a glance. For the production of some needle bar parts, the zero one modified production equipment and the six station production line need only one person to look after them; Moreover, in terms of management, zero one makes every worker reach the saturation state without exceeding the labor intensity, so that the labor pressure of every worker is small and the burden of the enterprise is reduced, which greatly improves the production efficiency and saves ineffective labor.

In the research and development of shaft parts, zero one spared no effort to constantly break through itself, aiming to create qualified and suitable parts for customers, so that products can better serve sewing machines and other fields. Zero one precision mechanical parts bring vital significance to precision machining!
