1. Careful selection of materials: The first step in building a solid foundation for linear bearing production is to focus on the careful selection of materials. High-quality cold-drawn steel, hot-rolled or cold-rolled steel strips are used to ensure that the carbon content of the material is maintained within the ideal range of 0.15% to 0.25% to meet the needs of bearings of different sizes. In addition, precise control of material hardness is key. Too soft or too hard is detrimental to the long-term performance of the bearing.
2. Cold extrusion technology: The art of shape shaping. The next process is cold extrusion molding, which requires precise cutting of the material to the appropriate length, followed by pickling, cleaning, and cold heading operations until the basic shape of the linear bearing is formed. The core of this stage is to closely monitor the quality of the material to ensure that the processing process does not damage its intrinsic properties.
3. Heat treatment: Strengthening the intrinsic quality After cold extrusion, the heat treatment process begins immediately, aiming to optimize the microstructure of the steel and improve its comprehensive mechanical properties. This process covers two major technologies: tempering and quenching. The former is suitable for high-carbon steel to balance hardness and toughness; the latter is for low-carbon steel and aims to enhance hardness. The two complement each other and jointly create a solid "skeleton" for the bearing.
4. Precision trimming: Details determine perfection. Bearings that undergo heat treatment also need to undergo a series of precision machining, such as turning, grinding and tooth surface treatment. Each link has strict requirements for accuracy, aiming to ensure the high precision and perfection of the bearing. roundness performance. This stage not only tests the accuracy of high-end equipment, but also relies heavily on the superb skills of technicians.
5. Precision assembly: After the overall precision processing of the construction function is completed, it enters the assembly stage. Using a variety of professional tools such as locks, hammers and trial fitting plugs, and following strict procedures and specifications, each bearing is carefully assembled to ensure that it is fully functional, stable and reliable.
