为了使具有减振效果的变速铣削加工方法能在生产中推广应用，以长春市第二机床厂生产的ＸＤ５０３２型立式升降台铣床为基型，首次研制开发了一台ＸＤ５０３２／ＢＱ型变速切削铣床。主传动采用交流变频调速方式调速，选用ＳＴＤ工控机作为主传动系统的主控单元，研制开发了一套变速切削铣床主轴转速微机控制系统。
In order to promote the application of variable speed milling with damping effect in production, based on XD5032 Vertical Lifting Milling Machine manufactured by No.2 Machine Tool Plant of Changchun City, a XD5032 / BQ variable speed cutting machine Milling machine. The main drive using AC variable frequency speed control method, the selection of STD IPC as the main drive system of the main control unit, developed a variable speed milling machine spindle speed microcomputer control system.
