Vertical drilling machine is a metal-cutting machine tool with a vertically arranged spindle and a fixed center position. It is divided into two types: square column vertical drilling machine and cylindrical vertical drilling machine. The spindle sleeve of the machine achieves axial feed through rotation. The worktable can be adjusted in height along the column guide rail. It is equipped with a manual and micro-motion dual-mode feed system and an ultrasonic quenched guide rail. It is commonly used in mechanical manufacturing and repair factories for processing holes in medium and small-sized workpieces, and supports operations such as drilling, tapping, reaming, and tapping threads.
