1995年5月在意大利米兰举办的11.EMO上,日本森精机制作所展出的MV-40B型装有磁浮轴承的高速立式加工中心,引起了人们极大关注。 粗加工领域也可实现高速化 为了提高机械加工的生产效率,已经在高速高效化、提高设备开动率、自动化和柔性化等方面采取了各种措施和技术,尤其是高速高效化这一古老而又新颖的课题,一直是设计及技术人员的最基本、最重要的研制目标。高速切削的优点是非常显著的:切削时间短,加工表面粗糙度好,切削抗力小,工件受热小,刀具寿命长。现今机床的主轴还是使用滚珠轴承,其允许转速(d·N值)限定了主轴外径,因而限定了主轴的最高转
In May 1995 held in Milan, Italy 11.EMO, the Japanese Mori Seiki produced by MV-40B maglev bearings equipped with high-speed vertical machining center has aroused great concern. Roughing can also achieve high speed In order to improve the machining efficiency, has been in the high-speed and high efficiency, improve equipment startup rate, automation and flexibility and so has taken various measures and technologies, especially high-speed and efficient this ancient and The new topic, has always been the design and technical staff of the most basic and most important goal of development. The advantages of high-speed cutting is very significant: cutting time is short, the surface roughness, cutting resistance, workpiece heating is small, long tool life. Today’s machine tool spindles also use ball bearings, which allow the speed (d · N value) that defines the outer diameter of the spindle, thus defining the maximum spindle rotation
