    How to produce miniature metal parts with deep holes?

    How are microperforated metal pieces manufactured? PTJ has introduced in detail how to make a continuous die cold extrusion micro deep drill. How do you make a hole in a metal part with a relatively thin microhole? Only the hardness of the punch is required to be higher than the hardness of the material.How do you make a metal part with fine holes that has a hole depth that is at least three times the diameter of the hole? According to the laws of physics, the depth of the hole is more than three times the depth of the opening,

    Why is a micrometer an essential tool for making quality parts?

    What is a micrometer? A micrometer is a sensitive tool for accurate measurement of length dimensions. This is one of the most important measuring instruments to date. It has a rigid C-shaped frame. There is a fixed anvil on one side and a movable spindle on the other side. The feature to be measured is placed between these two and the thimble is rotated to close the spindle. Markings on the sleeves and thimbles, called vernier scales, show the exact physical dimensions of the feature.Is a micrometer an alternative to digital measurement? Micrometer and other analog devices have been added
