temperature-rise and high-speed performance for machine tool main spindles. By optimizing the internal design, temperature rise of both bearings has been reduced to approximately half compared with normal types. These bearings can reduce power consumption for cooling machine tools, which is effective for energy saving.
−Development of High-speed Angular Contact Ball Bearings for Machine Tool Spindles "High Ability Bearings"− 40 KOYO Engineering Journal English Edition No.161E (2002) 3. 2 Test Result of Type 1 Type 1test bearing, in which both materials of raceways
can even reach 1000 kg which proposes extremely high requirements in carrying capacity and stiffness for the machine tool spindles. As a result, oil hydrostatic spindles are normally adopted in large ultra-precision drum lathes to achieve high carrying capacity up to 3000 kg and stiffness more than 850 N/μm .
NSK's solution to these problems is the ROBUST series of bearings, designed for ultra high-speed spindles. The ROBUST series of ultra high speed bearings employs a larger number of smaller diameter balls as their rolling elements, enabling them to operate at rotational speeds some 20 percent higher than conventional designs.

A machine tool may have several spindles, such as the headstock and tailstock spindles on a bench lathe. The main spindle is usually the biggest one. References to "the spindle" without further qualification imply the main spindle. Some machine tools that specialize in high-volume mass production have a group of 4, 6, or even more main spindles.

This study was focused on the theoretical modeling and numerical simulation about the dynamic characteristics of spindle system of ultra-high speed grinder. Based on the rotor dynamics and structural system dynamics, a dynamic model was established using the transfer matrix method and the overall transfer matrix method. The critical speeds of first three orders, the modes of variation and ...
The spindle is a key component for ultra-high-speed grinding machines and covers nearly 60% of the machine cost . Rapid acceleration of 6 m/s 2 and the coolant braking effect are the main issues that determine the high idle power of nearly 50% of the ultra-high-speed spindle output . Spindles with high power and high rotational speed are ...
Ball screw support bearings are designed to provide maximum axial rigidity and improved feeding accuracy for use with precision ball screws. They are high accuracy angular contact thrust bearings which are superior to combinations of standard angular contact bearings or arrangements of radial and thrust bearings for ball screw applications.
What benefits can aerostatic tool spindles bring to the CNC industry? The ultra-precise nature of our tool spindles allows customers to machine parts with an optical surface finish. For example, new LED-based head-light designs for cars require the precise machining of hundreds of LED sockets with an optical surface finish.
