High-Performance CNC Drilling for Stainless Steel Discs
In modern precision manufacturing, the need for clean, durable, and thread-ready holes in stainless steel discs is growing rapidly — especially across industries such as automotive, food processing, energy, and industrial equipment. Traditional drilling methods often produce burrs, weak threads, or deformation when working with stainless steel. That's why DUOMI CNC's CNC drilling machine for extrusion holes in stainless steel discs has become a powerful and efficient solution for metal fabricators worldwide.
This advanced technology allows manufacturers to achieve chip-free, strengthened holes in stainless discs through a friction-based extrusion process — also known as thermal friction drilling — all controlled by CNC automation for precision and speed.
What Is Extrusion Drilling?
Extrusion drilling, sometimes called friction drilling or thermal drilling, is a chipless machining technique that uses high-speed rotation and downward force to generate heat through friction. This heat softens the stainless steel material at the drilling point, allowing the tool to form a collar or sleeve by reshaping — not removing — the metal.
When combined with a CNC drilling machine, this process becomes fully automated, repeatable, and scalable for high-volume production. The resulting holes are stronger, burr-free, and ideal for threading, especially in thin or flat stainless steel discs used in critical assemblies.
Why Use CNC Drilling for Extrusion Holes in Stainless Discs?
Stainless steel discs are used in numerous high-stress and high-precision applications. These components often require threaded holes that maintain structural integrity and sealing performance. Here's why CNC extrusion drilling is ideal:
✅ Chipless operation: No metal waste or clogging, and reduced cleaning time.
✅ Stronger threads: The extruded collar allows deeper thread engagement.
✅ No distortion: Prevents cracking or warping of thin-walled stainless discs.
✅ High precision: CNC control ensures perfect hole placement and depth.
✅ Ideal for automation: Excellent integration into robotic or multi-station production lines.
When you need both accuracy and durability in a demanding material like stainless steel, a CNC drilling machine for extrusion holes in discs is the ultimate tool.
