高速度、高精度、高效率和高刚度已成为当今数控机床发展的主要方向,普通龙门机床一般只能进行单面,当零件的另一个表面时,需要加装一个直角转换头或者调转零件的面后重新装夹,这不但增加了机床操作者的劳动强度,影响效率,并且重新定位装夹也降低了零件的精度,为了弥补这些不足,龙门三自由度工作台便应运而生。五面体三自由度工作台一次装夹就能实现工件五个表面的,这大大提高了零件的精度和效率,降低生产成本,因此五面体三自由度工作台成为当前数控机床行业重点研究的对象之一。
The paper introduces the principle and selection of ball screw, ball screw system of production, application and other aspects were introduced. Including the principle and type selection, parameter selection, manufacturer of precision, circulation mode selection, selection and matching host selection.
High speed, high precision, high efficiency and high stiffness has become the main direction of the development of CNC machine tools, general Longmen machine tool generally only one side quenching, when another surface hardening of parts, need to install a right angle conversion or transfer quenching surface after the heavy clothes clip, which not only increase the labor intensity the effect of quenching machine tool operators, efficiency, and re positioning and clamping also decreases the quenching accuracy of parts, in order to make up for these deficiencies, Longmen five axis surface induction hardening machine will emerge as the times require. Five sides of five axis surface induction hardening machine once clamping workpieces can be realized five surface quenching, which greatly improves the accuracy of quenching and the quenching efficiency, reduce the production cost, so the five sides of five axis surface induction hardening machine has become one of the key research object number controlled machine tool industry.
其中着重介绍了滚珠丝杠的原理及选用原则,系统地对滚珠丝杠生产、应用等环节进行了介绍。包括种类选择、参数选择、精度选择、循环方式选择、与主机匹配的原则以及厂家的选择等。

数控NC阶段(1952年-1970年)
早期计算机的运算速度低,对当时的科学计算和数据处理影响还不大,但不能适应机床实时控制的要求。人们不得不采用数字逻辑电路"搭"成一台机床专用计算机作为数控系统,被称为硬件连接数控(HARD-WIRED NC),简称为数控(NC)。随着元器件的发展,这个阶段经历了三代,即1952年的第一代—电子管;1959年的第二代—晶体管;1965年的第三代—小规模集成电路。

1946年诞生了世界上第一台电子计算机,这表明人类创造了可增强和部分代替脑力劳动的工具。它与人类在农业、工业社会中创造的那些只是增强体力劳动的工具相比,起了质的飞跃,为人类进入信息社会奠定了基础。6年后,即在1952年,计算机技术应用到了机床上,在美国诞生了第一台数控机床。从此,传统机床产生了质的变化。近半个世纪以来,数控系统经历了两个阶段和六代的发展。
