Large gantry drilling machine

Large gantry drilling machines are mainly suitable for processing large frames and boxes of metallurgical, mining, and general machinery with single piece and small batch consumption properties, such as boring, drilling and expanding holes, scraping flat surfaces, and stopping milling with milling cutters. The main local spindle and square slider of the machine tool. The spindle is supported by a square slider, which enhances the rigidity during milling and is suitable for milling large parts. The extension of the square slider improves the performance close to the workpiece processing surface. At the same time, it also supports the boring shaft, enhancing the rigidity during boring. The end of the square slider is suitable for installing various processing accessories to stop flat and vertical milling, boring, drilling and other processing, which can further expand the application range of the machine tool.

There are many varieties of large gantry drilling machines, which are generally distinguished according to planning methods and applicable scope.

※ Lift table drilling machine: horizontal and vertical, mainly used for processing small and medium-sized parts, widely used.

Longmen drilling machines: including Longmen boring and drilling machines, Longmen milling machines, and double column drilling machines, all used for processing large parts.

Single column drilling machine and single arm drilling machine: The milling head of the former can move along the column guide rail, and the worktable can make longitudinal feed; The latter's vertical milling head can move along the cantilever guide rail, and the cantilever can also adjust its height along the column guide rail. Both are used for processing large parts.

※ Non elevating worktable drilling machine: There are two types of worktable: the conical worktable and the circular worktable, which are medium-sized drilling machines between the elevating worktable drilling machine and the gantry drilling machine. The vertical movement is completed by the milling head lifting and lowering on the column.

Instrument drilling machine: a small lifting table drilling machine used for processing instruments and other small parts.

Tool drilling machine: used for mold and tool manufacturing, equipped with various accessories such as vertical milling head, angle worktable, and insertion head. It can also stop drilling, boring, and insertion processing.
