Abstract

The invention relates to a metal processing machine tool, in particular to a vertical finish-milling machine which comprises a gantry column, a transverse beam, a main shaft box mechanism and a working table mechanism, wherein balance oil cylinders are respectively and symmetrically arranged on two sides of a ram of the main shaft box mechanism; one end of each balance oil cylinder (the shaft end of the oil cylinder) is fixed on the ram; the other ends of the balance oil cylinders (the body ends of the oil cylinders) are fixed on a drag plate. When the ram drives a main shaft box to move upwards and downwards, the situation that a cutter drops off can be avoided no matter what the moving amplitude is; moreover, when a milling cutter moves suddenly, the moving speed of the main shaft box can be effectively buffered by the balance oil cylinders; due to adoption of the balance oil cylinders on two sides of the ram, the ram is relatively stable, the processing precision of the finish-milling machine can be relatively high, and a processed workpiece is relatively good in quality. After the guide tracks of a working table base are lengthened, the working table can be completely supported, and the bearing property of the working table is improved. Three transverse beam guide tracks are provided, so that abrasion of the guide tracks is alleviated, and the service lives of the guide tracks are prolonged.
