Trepanning is a machining technique for drilling large diameter holes in materials, particularly where there is a requirement to retain the solid core or when tolerances are not particularly tied up. Instead of drilling the whole diameter, trepanning only drills an annulus (a ring) around the outsid

Internal hole turning, also known as boring, is the process of enlarging the inner hole of a workpiece or processing the inner surface of a hollow workpiece using turning methods. It can be processed using most of the outer circle turning techniques. Today we will explore common troubles in inner ho

The causes of abnormal machining accuracy faults are highly covert and difficult to diagnose. Today I have summarized the 4 diagnostic principles and 5 diagnostic methods for everyone. Do you all know them?

Aluminum alloy is not unfamiliar to everyone, as it is cheap, beautiful, and durable, and has been widely used in various industries. Among them, there is a type of aluminum alloy that has attracted much attention due to its widespread application in the aerospace field, which is aluminum lithium al
