Metal Drilling Machines for Tubes and Profiles

A round tube presents a curved surface; a profile or plate presents flat faces. The required hole position, orientation and spacing determine how the part is held relative to the tool. Selected configurations provide automatic tube feed and controlled rotation for repeated holes around the component.

The applicable cycle depends on section, material, length, hole diameter and hole count. Garboli drilling applications include steel, stainless steel, aluminium, brass and titanium. Tooling and operating settings must suit the selected material and machine.

On a flat profile face or plate, perpendicular drilling creates a hole normal to the surface. Angled drilling creates a hole at a specified inclination. For tubular components, the relationship between the tool axis, tube geometry and hole position must be defined. Available orientations depend on the machine configuration.

Selected arrangements also provide flow drilling and threading. These functions serve a specified hole or connection requirement and may be included alongside conventional drilling in the working cycle. They are not standard features of every drilling machine.

Garboli Range drilling machines describe the line application. Where the finished component also requires grinding, satin finishing or polishing, metal finishing machines provide separate surface operations. Share the component drawing, material and hole layout with Garboli to discuss the required positioning, tooling and production cycle.
