Core Advantages
Continuous Innovation, Sustainable Development !
OBR inherits advanced mechanical spindle design and manufacturing concepts, focusing on bearing span optimization design, spindle labyrinth dust and waterproof design, high torque and load capacity, high-precision and high-speed design for direct-coupled spindles, belt spindles, gear-driven spindles, electric spindles, CNC lathe spindles, and customized spindles.
Automated computer testing and monitoring of the entire process of spindle finished products
Full process data of spindle products: running in speed test, spindle temperature rise monitoring, spindle vibration data acquisition, spindle thermal elongation measurement.
Material Selection and Heat Treatment
It is the basic guarantee for spindle stability and lifespan. OBR takes particular care in selecting materials for spindle core shaft, spacer ring and bushings. Technicians select special materials from the source of factory and reach long-term material stability agreements with material suppliers, ensuring the factory's stable demand for raw materials. The heat treatment of spindle various components undergoes processes such as normalizing, quenching and tempering, carburizing (deep cooling or nitriding), etc. Each heat treatment is crucial to the finished spindle, and each one related to the final usage effect of the spindle. Mature and stable processes are key factors for the success of OBR products.
Advanced Processing Equipment
It is the key to manufacturing high-precision spindles. OBR has introduced top-level grinding equipment from around the world, such as Japanese TAIYO KOKI , (DMG) MATE 85 vertical grinding machine, the Swiss STUDER S31 universal grinding machine, the Swiss FISCHER 1500 center hole grinding machine, Taiwan COMORK and Taiwan E-tech Hybrid ID & OD Grinder grinding machines, etc.
Fully Controlled Assembly process
Ensure that each spindle is assembled according to standard procedures, from the tolerance matching of spindle core shaft and bushing to the tolerance matching of bearings with front cover, front spacer ring, middle spacer ring, and rear spacer ring. Every detail is under standardized process control, maximizing the first-pass yield during the assembly process.
