  • Design and Analysis of Machine Tool Spindle

    2017-7-6 · detailed later. From the design principle, the front end bearing must be as close as possible to the spindle nose in order to increase the static stiffness of the spindle at the tool tip. While it is the most critical bearing in terms of the dynamic stiffness of the spindle, changing the position of

    2008-12-15 · one can not predict where the part will be made. Dimensions should always be based on design requirements. If it is known that a part will be produced always by CNC methods, then establish dimensions without limits that conform to CNC machine capabilities. Bilateral profile tolerances are also recommended for the same reason.

  • Tools & Trends in Product Development

    2010-1-1 · The bearing stiffness is modeled as a function of ball bearing contact angle, preload caused by the external load or thermal expansion of the spindle during operation. The equation of motion is derived in matrix form by including gyroscopic and centrifugal effects, and solved to obtain natural frequencies, vibration mode shapes and frequency …
