Technology Overview
What is CNC Drilling?
CNC (Computer Numerical Control) Drilling is a widely used subtractive manufacturing technology that involves the use of computers to control machine tools. These machine tools, in the case of CNC drilling, are drills that are used to create holes of different diameters and depths in a variety of materials.
Principle of CNC Drilling
At the core of CNC drilling is a computer-controlled system that directs the drill bit’s movements. The drilling process begins with a digital 3D design of the part, created using CAD (Computer-Aided Design) software. The 3D design is then converted into machine instructions using CAM (Computer-Aided Manufacturing) software. These instructions, or G-codes, control the movement, speed, and positioning of the drill bit.
Advantages of CNC Drilling
CNC Drilling machines can have multiple axes of movement. Most commonly these are 3-axis machines, but there are also 4 and 5-axis machines that offer even more flexibility, allowing the drill bit to approach the workpiece from different angles and in different positions.
One of the key advantages of CNC drilling is its precision. It can achieve very tight tolerances, often as tight as ±0.0005″ (0.0127mm). This high degree of accuracy is consistent across all parts produced, regardless of the production volume.
Another advantage is the ability to drill complex and intricate patterns that would be difficult or impossible to achieve manually. This makes CNC drilling suitable for a wide range of industries, including aerospace, automotive, electronics, medical, and more.

-Mason Lucas, Purchasing manager at Alpha Manufacturing
ProLean has consistently provided me with excellent milling service using their 5-axis CNC machine. I've worked with many contract manufacturers, but other than ProLean, I've never found accurate tolerance on my parts.
We were able to satisfy our client's needs thanks to Prolean's prompt reaction. Additionally, I frequently found that their engineers are always willing to innovate creatively to deliver top-notch service.
-Tanesha Adesina, Technical manager at Bossard Technology
I needed a quick prototype for my research, but I had no idea that their CNC machines were so sophisticated and could produce it in just three days. The prototype was quite precise and fell within the tolerances of the CAD I provided.
Thumbs up! Not just selling, nothing else count for them; Service Service Service, first!
