Features and Characteristics of Motorized and Non Motorized Milling Spindles
International Journal of Engineering and Advanced Technology, 2020 The Cutting process used in milling is one of the most common type of industrial machining methods. Similar to traditional milling spindles, the motor driven spindles are fitted with an integrated motor, thereby eliminating belts and gears for the transmission of power from the motor to the cutting tools.

Antagonistic Spindle Motors and MAPs Regulate Metaphase Spindle Length and Chromosome Segregation [PDF]
Current Biology, 2013 Metaphase describes a phase of mitosis where chromosomes are attached and oriented on the bipolar spindle for subsequent segregation at anaphase. In diverse cell types, the metaphase spindle is maintained at characteristic constant length [1-3]. Metaphase spindle length is proposed to be regulated by a balance of pushing and pulling forces generated by

Microtubule motors in spindle and chromosome motility [PDF]
European Journal of Biochemistry, 1999 Many of the kinesin microtubule motor proteins discovered during the past 8–9 years have roles in spindle assembly and function or chromosome movement during meiosis or mitosis. The discovery of kinesin motor proteins with a clear involvement in spindle and chromosome motility, together with recent evidence that cytoplasmic dynein plays a role in ...
