The Construction Design And General Performance Analysis Of High-speed Motorized Spindle Which Used In NC Machine

High-speed machining is an advanced manufacturing technology which can increasing productivity, precision, quality of the product and reducing production costs by raising cutting speed dramatically. Now, nothing can stop its development. High-Speed machine tool is the precondition for realizing high-speed machining. High-speed motorized spindle is a crucial unit of the high-speed .So, it is important to optimize the construction design on improving the performance of the high-speed machine tool by studying the static and dynamic characteristics of High-Speed motorized spindle.In this paper, the static and dynamic performances of the High-Speed motorized spindle are studied with ANSYS software by FEA.Details of studies are as follows,1. The construction of the motorized spindle is designed based on solving some critical problem in construction design such as choice of bearings, design of dynamic balance, design of geometric precision, static estimate of the spindle's construction parameter.2. The principal parameter of the spindle such as the cutting force the...
