How To Do CNC/EDM Drilling

CNC/EDM drilling is a technique that's used to make precise holes in wood, metal and other materials. It's great for making custom hardware or handles for DIY projects, as well as adding a finishing touch to your creations

There are many different types of CNC/EDM drill rigs available on the market today, but this article will focus on the most common setup: an automated milling machine with a drill head attached to it

The concept is simple: you mount your material on the machine and use it to drill out holes in whatever you want. There are countless designs available online that you can copy or modify for your own needs, so don't be intimidated by the process

You can also find online tutorials that walk you through how to set up an automated milling machine using an affordable router table attachment (like this one), which is what we'll be focusing on here.

What is CNC Drilling

CNC drilling is a machining process in which a computer numerical control (CNC) machine is used to drill holes into a material. This process is commonly used in creating precise and uniform holes in a variety of materials, including metals, plastics.
The CNC drilling process typically use a rotating spindle and a drill bit. The spindle is driven by a motor and controlled by the CNC machine, position the locations of holes and drill it.

How Does CNC Drilling Work

CNC Drilling machine instruct the spindle movement and specifies the size and location of the holes to be drilled.

During the CNC drilling process, the material is held securely in place on the machine table, and the drill bit is carefully guided by the CNC machine to create the desired holes. The speed, depth, and angle of the drill bit can be precisely controlled by the CNC machine, allowing for high levels of accuracy and repeatability.

CNC drilling can be used to create a wide range of hole sizes and shapes, including round holes, square holes, and other complex geometries. This versatility makes CNC drilling a valuable tool in many manufacturing applications, including the production of tooling parts, assembly parts, and fabrication parts.
