[Processing Example] Hastelloy Fine Hole Machining

Introducing a machining example of difficult-to-cut materials: drilling 20mm from both sides with a drill to create a 0.2mm hole that passes through 40mm!

We would like to introduce an example of fine hole machining of the representative difficult-to-machine material Hastelloy C276. In lathe processing, holes are drilled from both sides by 20mm each, resulting in a 0.2mm hole that is 40mm deep. The relationship between hole depth and diameter is expressed as L/d, where L is the depth and d is the diameter. Normally, an L/d of 10 is already considered difficult, but in this case, it is L/d 200. Since we use a 0.2mm drill, it is usually too thin and prone to breaking or bending. Additionally, if the center is even slightly misaligned, the holes will not connect, but our company can drill them straight. 【Case Overview】 ■ Material: Hastelloy C276 ■ Processing Details: 0.2mm hole drilled through 40mm ■ Hole Depth / Diameter: L/d 200 *For more details, please refer to the PDF document or feel free to contact us.
