To realize the automatic engraving of the production date on the product, macro programs are indispensable. On the road to learning CNC programming, I come into contact with people

As a veteran in machining, you have read countless drawings and processed countless parts. When we talk about "form and position tolerances", it is both theoretical and p

Taboos in the application of milling tools Taboo for precision detection after the tool is installed on the spindle When machining workpieces with higher precision or using older e

Why are engineering drawings and mechanical drawings blue? These drawings are blue, which is related to their drawing methods. These drawings are not drawn or printed, but "ex

Machining is the process of using a machine to process a target shape. When designing parts and machinery, it is necessary to know what kind of machine can be used to perform what

How O-rings are produced 1. Compression molding materials are manually added to the mold before the upper and lower molds are combined. Since this process is time-consuming, this p

What is anti-rust oil? Rust often refers to the corrosion of ferrous metals in the air due to the electrochemical reaction caused by the participation of water and oxygen. Anti-rus

Plunge milling, also known as Z-axis milling, is one of the most effective methods for high-removal metal cutting. For curved surface machining, grooving, and machining with large

CNC lathe is one of the most widely used CNC machine tools. It is mainly used for machining symmetrical rotating parts, such as shaft parts, inner and outer cylindrical surfaces of

1. Characteristics of cold stamping dies ① Cold punching die: wear, chipping, fracture; ② Cold drawing die: wear, bite, scratch; ③ Cold heading die: brittle fracture, cracking, wea

We know that to obtain qualified injection molded products, at least two points must be kept in mind: the flow speed of the melt in the mold cavity during injection molding should

(1) The punch wears too fast. The main reasons are: ① The gap between the molds is too small. Generally, the total gap between the molds is 20% to 25% of the material thickness. ②
