Drilling a hole in a part or a workpiece may seem like a simple operation, but it is a very complex process that must be completed with complete precision. This is true for both precision parts and components and general parts as if the drilling operation is not correct, the manufacturing and fabrication can become a significant issue.
Options for Drilling
There are different options to consider for any drilling operation. With specific types of parts and components, precision drilling is often a central consideration, so the choice of a shop offering CNC turning centers and vertical milling centers and CNC lathes is often a consideration. For some types of applications, manual equipment may also be the best choice, and with experienced operators, even highly precise drilling can be completed quickly and effectively.
Correct Drills and Equipment
A common challenge with new machine shops and drilling operation problems is often the lack of the right equipment for the job. This includes both the actual drilling systems as well as the correct drill bit and equipment setup.
Matching the drilling system with the right bit and the correct speed and system configuration is critical to creating precision drilling services for one piece or for large volume orders.
Inexperienced Operators
While CNC drilling operations are designed to be precise and to provide the same drilling process time after time, the operator is still a critical factor. Knowing how to monitor the drilling action, determining when to change out drill bits, and making any adjustments when there are changes in the material are all potential issues if the operator is not monitoring the equipment.
The deeper the hole and the more precise the hole has to be, the more issues of vibration in the process can throw off even the most carefully designed drilling program. Issues such as the incorrect volume of coolant to flush out chips, blunt or dull cutting tools, and lack of understanding of the speed of the drilling process in relation to the spindle and holder movement can also impact the quality and the efficiency of the operation.
