Rigidity of high-speed motor spindles
Werkstatt und Betrieb, 1999Rigidity of high-speed motor spindles. The most relevant factors for the static operational rigidity of motor spindles were analysed, and the finite element method was used for calculating the effects of configuration, type, prestress and heat-up of bearings as well as of the temperature range of the spindle nose on the operational rigidity of motor ...

Effect of spindle speed on clamping force in turning
Journal of Materials Processing Technology, 1993Abstract A remarkable development has taken place in recent years in the field of tool materials that has resulted in a several-fold increase in the cutting speed of materials. In line with this, industrial machine-tool builders are also producing machines offering increasingly higher speeds, but such higher speeds have brought new problems.

Design of the High-Speed-Spindle Motor
2012As explained in Sects. 1.2 and 1.3 of the thesis Introduction, the PhD project started within the Dutch Microfactory framework with the goal of development of a built-in electrical spindle drive which would facilitate high rotational speed of the spindle and accurate micro-milling.

Design of intelligent spindle for high speed machining
Proceedings of the Second International Conference on Intelligent Processing and Manufacturing of Materials. IPMM'99 (Cat. No.99EX296), 1999Summary form only given. The spindle is the most important component in a high speed CNC machine tool. Its thermal and dynamic behaviors are almost decided by the drive system and the support system of the spindle. Some special requirements for high speed spindles must be satisfied; C-axis control is also required.

Measurement of Cutting Torque by Speed Increasing Spindle
2006A method of measuring cutting torque during milling using a small end mill, using a speed-increasing spindle with planetary gears is proposed. Its viability was confirmed by experiments using three types of end mill and the workpiece of NAK55. By attaching a few parts to a commercially available speed-increasing spindle, torque can be measured at a low
