Digitalisation is driving the evolution of the machine tool industry. Equipment standards based on geometric accuracy, motion accuracy, transmission accuracy and dynamic accuracy have become key indicators for assessing machine tool precision. As the core mother machines of industrial production, their performance profoundly influences a company’s productivity and competitiveness. Machine tools serve as the vehicle for advanced manufacturing technologies and the fundamental means of production for the equipment manufacturing industry; they are the foundational equipment of the sector, primarily serving industries such as automotive, defence, agricultural machinery, construction machinery, power equipment, railway locomotives and shipbuilding. The machine tool industry holds strategic importance both economically and technologically. Its capabilities in equipment design and manufacturing processes, underpinned by mechanical engineering and digital control technologies, place it at the forefront of the Fourth Industrial Revolution. As digitalisation becomes the core driving force, exciting opportunities for further automation have emerged. The key objective of optimising overall equipment effectiveness, centred on reliable performance and sustainability, is now more critical than ever.
The performance of spindle units is critical to the quality of machined parts and machine uptime; spindle units play a vital role in machining operations. Spindle designs range from belt-driven spindles to motor-integrated spindles and are used in a wide variety of machines, from high-speed milling to high-load turning operations. Machine tool performance is being pushed to its limits to maximise output; at the same time, machine operations are becoming increasingly complex. The demand for higher speeds and faster development places extremely high demands on the machine’s core components, particularly the bearings in the spindle unit. Bearings offering high running accuracy, high-speed performance and high system rigidity are the ideal choice for machine tool spindle units. Furthermore, the design of these bearings minimises noise, vibration and heat generation.
A wide range of ultra-precision bearing types, series, designs, variants and dimensions, combined with optimal design to enhance equipment performance, machine uptime, rotational speed and precision. In response to recent environmental requirements, we have pioneered the introduction of grease replenishment systems for machine tool spindle bearings, enabling grease lubrication to be used in high-speed applications where previously only oil lubrication was feasible.
