THS5640立式铣镗加工中心的主轴加工过程分析

摘要

THS5640 vertical boring and milling machining center is a kind of high precision CNC processing equipment,the spindle is one of the key parts of the machine tool.Because THS5640 spindle is primarily working under high speed cutting,torsion moment and bending moment are high,so in addition to its high rotation accuracy and good vibration resistance,but also its good torsional stiffness and bending stiffness.In order to meet the work requirements,the machining process analysis on the THS5640 spindle is very necessary.This article analyzes the structure characteristics,technical requirements,material and heat treatment of the THS5640 spindle,and draws up a detailed instruction to machining process for the spindle.%THS5640立式铣镗加工中心是一种高精度的数控加工设备,其主轴是机床的关键零件之一.由于THS5640主轴主要是在高速切削下工作的,承受较大的扭矩和弯矩,因此除要求其具有极高的回转精度和良好的抗振性外,还要求其具有较好的扭转刚度和弯曲刚度.为了能满足这些工作需要,对THS5640主轴的加工过程进行分析是非常必要的.通过对THS5640主轴结构特点、技术要求、材料及热处理的分析,拟定并详尽说明了该主轴的加工工艺过程,具有一定的推广价值.
