Machine Tools

Digitalisation is driving progress in the machine tool industry, with equipment standards based on geometric accuracy, motion accuracy, transmission accuracy and dynamic accuracy having become key indicators for assessing machine tool precision. As the core ‘mother machines’ of industrial production, their performance has a profound impact on enterprises’ 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 constitute the foundational equipment of this 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. With digitalisation emerging as the core driving force, exciting opportunities for further automation have arisen; the key objective of optimising overall equipment effectiveness, centred on reliable performance and sustainability, is now more important than ever.

The performance of the spindle unit is crucial to the quality of machined parts and the uptime of the machine; it plays 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 operation is becoming increasingly complex. Demands for higher speeds and faster development have placed 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, these bearings are designed to minimise noise, vibration and heat generation.

A wide range of ultra-precision bearing types, series, designs, variants and sizes, combined with optimised designs to enhance equipment performance, machine uptime, rotational speed and accuracy. 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 effectively in high-speed applications where previously only oil lubrication was feasible.
