Patent leather, a term often heard in life, refers to a processing technique. Patent leather is also divided into leather and PU leather patent leather, how to distinguish the difference between the two? Here's an introduction to the patent leather and how to identify genuine and fake cow leather . First, what is patent leather? Patent leather is a kind of processing technology. It refers to leaching paint on leather or PU leather. It is characterized by its bright color, natural, waterproof, moisture-proof, not easily deformed, and easy to clean and care. The processing of the surface into a bright, sturdy leather is an apparel material with a strong surface effect and style characteristics. A variety of colorful patent leather and imitation patent leather tight-fitting fashion, as well as a fine patent leather leather shoes, is a fashionable product nowadays. In the late 1990s, even athletic shoes and casual shoes were made of patent leather. Second, how to identify true and false cow leather 1, elasticity Cow leather and leather are all flexible. This is usually the case when we buy shoes and bags. 2, smell Good-quality bovine leather does not generally have a pungent smell, and artificial leather does the opposite. 3, incision There are fibers in the cuts of the bovine patent leather. These fibers are similar to the half-cut lean cuts that we usually see. The artificial leather contains cloth threads, which is very easy to see. 4, wrinkles The bovine patent leather is soft, so the wrinkles on the upper and the wrapper surface will be more obvious, while the artificial leather has no such phenomenon. 5, feel Compared with artificial leather, bovine patent leather has good air permeability and excellent hand feeling. It is not easy to wear the feet during wearing and it is not easy to sweat and stuffy. 6, price The price of bovine leather is relatively high, so it is unrealistic to have a genuine bovine leather look if you have a low price. As the saying goes, it's what it means to say what you pay for. The above is about the description of what is patent leather and how to identify genuine and fake bovine leather. I hope I can help you. If you want to learn more about patent leather, please pay attention to this website decoration information channel. Leather fiber
In Custom Mechanical Components, Shaft Parts are suitable for maintenance operations of one or more Cnc Machined Parts. Shaft parts are one of the typical parts often encountered in hardware accessories. It is mainly used to support transmission parts, transmit torque and bear loads. According to the different structural forms of shaft parts, they can be generally divided into optical shafts, stepped shafts and special-shaped shafts. Three types of shafts; or divided into solid shafts, hollow shafts, etc.
Centering CNC lathe (centering machine / longitudinal cutting lathe) is a CNC machine tool mainly used for precision machining of shafts and non-standard shafts. It has a qualitative leap compared to CNC lathes in processing efficiency and processing accuracy The use of dual-axis tool arrangement greatly reduces the processing cycle time. By shortening the tool exchange time between the tool arrangement and the opposite tool table, the multiple tool table overlap function, the thread chip effective axis movement overlap function, and the direct spindle during secondary machining The indexing function shortens the idling time. The cutting tool is always processed in the clamping part of the spindle and the workpiece, ensuring that the accuracy of the processing remains unchanged. The maximum processing diameter of the core walking machine in the market is 42mm, which has a great advantage in the precision shaft processing market. This series of machine tools can be equipped with an automatic feeding device to realize the fully automated production of a single machine tool, reducing labor costs and product defect rates. Very suitable for mass production of precision shaft parts.
