Automatic Drilling and Punching Machine

Client: Leading Industrial Door Manufacturing Supplier

Part: Metal Fabrication with variable sizes

Machine supplied: Automatic drilling and punching solution

Overview: This system was designed and manufactured in order to give the customer the ability to perform automatic drilling and punching of features into a metal fabrication. The solution included easy adjustment to allow several sizes of fabrication to be handled.

Operators load a metal fabrication into this automatic drilling and punching system, the part is then automatically clamped into the location tooling and the drilling and punching operations are performed automatically. On completion of the cycle, operators unloaded the finished part.

The drilling is performed by single and twin spindle units positioned on either side of the system, these are mounted to drill holes horizontally. The punching is achieved using a hydraulic power pack and associated cylinders to punch through a number of holes. Swarf collection drawers are included under all machining operations to allow easy emptying and swarf removal from the machine. Drill bit and punch tool changeover is made straightforward by the tooling design and the inclusion of slides to allow the drills to be retracted for access.

The customer required this automatic drilling and punching solution to handle a number of variants. This was made possible using a handwheel on the RHS of the system to change the distance between the 2 sides of the machine. Automatic adjustment of the rear hole positions is included within this operation.

The system was PLC controlled and included broken tool sensing to ensure correct operation. Perimeter guarding was supplied with front access protected by safety mats.
