Teach you some unique skills that the master does not pass on, how to use the information on the blade box to choose the right blade
A very important piece of information on the blade box is the cutting parameter, which is also called the three cutting elements, which are composed of Vc=***m/min，fn=***mm/r，ap=**mm on the box. These data are theoretical data obtained by the laboratory, which can provide us with a reference va...Read more -
He engraved words on 0.01 mm thick aluminum foil paper, vowing to make Chinese manufacturing more powerful!
Use an ordinary CNC milling machine to process text on aluminum foil paper with a thickness of only 0.01 mm. If there is a slight deviation, the aluminum foil paper will be penetrated or even ruptured. Thin, soft and brittle materials are recognized worldwide as machining problems. With more tha...Read more -
Ultra-precision polishing technology, not easy!
I saw such a report a long time ago: scientists from Germany, Japan and other countries spent 5 years and spent nearly 10 million yuan to create a ball made of high-purity silicon-28 material. This 1kg pure silicon ball requires Ultra-precision machining, grinding and polishing, precision measure...Read more -
The Principle and Characteristics of the Welding Method of Seamless Track Rail
With the rapid development of high-speed and heavy-duty railways, the track structure is gradually replaced by seamless lines from ordinary lines. Compared with ordinary lines, the seamless line eliminates a large number of rail joints in the factory, so it has the advantages of smooth running, l...Read more -
Measures to Effectively Prevent End Cracks in Submerged Arc Welding Longitudinal Weld
In the manufacture of pressure vessels, when submerged arc welding is used to weld the longitudinal weld of the cylinder, cracks (hereinafter referred to as terminal cracks) often occur at or near the end of the longitudinal weld. Many people have conducted research on this, and believe that the ...Read more -
How to operate the vertical fixed welding of the riding tube sheet
Riding tube-to-sheet welding requires root penetration and good back forming, so the operation is more difficult. According to different spatial positions, the sitting tube-sheet welding can be divided into three types: vertical fixed flat fillet welding, vertical fixed elevation angle welding an...Read more -
