Precision machining and fabrication are a vital service offered by any reputable CNC machining shop. A key service offered in this regard is CNC drilling, a precision machining technique that is used to drill holes on a surface with very tight tolerances. Typically, in this drilling setup, the workpiece is attached or secured to the table while the drill bit is rotated and placed on the area that requires drilling. While the overall process is highly automated, it still requires some manual intervention and setup. This blog explores 4 steps that lead to a successful CNC drilling operation.
To execute the CNC drilling process, it is vital to first prepare the CAD design of the operation. In this case, operators enter dimensions of the hole as well as tolerances. This will determine various factors such as the tool path, rotational speed, and so on.
The computer-aided design (CAD) prepared the blueprint of the operation. But it is CAM (computer-aided manufacturing) that actually executes this design in real-time. So the next step is to upload the CAD design to the CAM software. Much like any CNC controller, the CAM software uses G-code to control the drilling machine.
There are three steps to this process. Firstly, the right drilling machine and drill bit must be selected. These will be attached to one or multiple spindles. Next, the workpiece is attached to the CNC drilling machine table by means of a clamp or other fixtures. Lastly, the right CNC program from step 2 is added to the drilling machine. This will dictate when the drill has to start and stop, and many other parameters.
With all the above-mentioned processes in place, the CNC drilling machine can finally be operated, allowing it to perform its task on the workpiece. It will accurately create the desired depth, diameter and profile of the hole as programmed in the CAM software. In this way, it is possible to achieve precision machining and fabrication using CNC drilling.
