Description

A double-head gantry CNC flange drilling machine with hydraulic chuck

Technical Field

The invention relates to the technical field of CNC drilling machines, and in particular to a double-head gantry CNC flange drilling machine matched with a hydraulic chuck.

Background Art

Flange connection refers to a detachable connection in which flange, gasket and bolts are connected to each other as a combined sealing structure. There are holes on the flange, bolts make the two flanges tightly connected, and gaskets are used to seal between the flanges. The holes on the flange are generally drilled by CNC drilling machines, which have high operating accuracy and fast drilling.

Currently, common CNC flange drilling machines generally use a single drill bit for drilling and manual positioning. The drilling efficiency is slow and the drilling accuracy is not high.
