Friction Drilling

An interesting process that creates a very useful hole in metals is friction drilling or flow drilling. Rather than using a fluted drill bit to cut a hole, friction drilling uses a conical bit coated made of a high heat-resistant material from the ceramic family to form the hole. In this process the bit is pressed into the target body …

High Speed Video Of Drill Tool

I love to see what is really happening at the interface of a cutting tool and there is no better way to see it that slowing down a high-speed video. Ingersoll Cutting Tools have once again made a high-speed video of one of their tools in action. This one is their Quad Drill+ cutting a half hole in 1018 mild …

Sheet Metal Stamping Fundamentals: Dies And Processes

This video from the Society of Manufacturing Engineers takes us through the fundamentals of dies and processes used in the sheet metal stamping operations. The video looks at single and multiple station stamping operations. Single Station Stamping Processes Compound Dies – used for only shearing operations such as cutting and hole punching. Combination Dies – combines shearing operations with forming or shaping operations in a …

Manual Metal Spinning

Here is an interesting video of a manual metal spinning operation. It shows a nose cone for a wind vane being made. This form is somewhat simple and much more complex shapes can be manufactured with metal spinning. Whilst automated or CNC metal spinning operations are available these days it is good to see how these processes are done by …
