What Is CNC Drilling & How CNC Drilling Works

Drilling is the cutting process in which the workpiece does not move, making the cutter move, aligning the cutter center with the hole center, and making the cutter rotate. CNC Drilling is primarily done on CNC machines including CNC milling machines and lathes. CNC drilling service produces round holes, typically for machine screws and bolts. Drilling can process CNC drilling parts with metals, hard plastics, wood and most other rigid materials. There are several types of drilling machines available for CNC, including these drill presses: Upright, Bench and Radial. When in use, the step-by-step process for CNC drilling includes:

  • The operator uploads and accesses the computer-aided design (CAD) or computer-aided manufacturing (CAM) file.
  • The operator installs the appropriate drill bit and secures the designated material on the table.
  • The operator starts the drilling process through the control panel or interface.
  • The spindle lowers, drilling the appropriate hole sizes and diameters.
