On July 7, the 3,000-ton/year high-purity polysilicon project of Sichuan Yongxiang Polysilicon Company in Wutongqiao District, Leshan City started construction, and the new plant began to operate. At the same time, the 6,000-ton/year polysilicon project settled in the building was officially pave ---MORE---
The WS welder concentrates the energy of the tungsten wire on a very small (0.2mm to 2.0mm) wire and melts the wire and the die base material in an instant (0.5ms to 20ms). After the melt is cooled, if the metallographic structure of the welded part is consistent with the mold base material, the wel ---MORE---
At present, China's machine tool industry is developing in five aspects of “high speed, compound, precision, intelligence and environmental protectionâ€, and various new technologies, new materials and new processes will be widely used. The market has increased demand for large-size, ---MORE---
As gear tool technology continues to advance, gear cutting machines that use these tools are constantly changing. Hartmuth Müller, chief technology officer at Klingelnberg GmbH, points out that the challenge of designing a bevel gear dry cutting machine is more challenging than designing a tool. ---MORE---
Not long ago, Yuan Yongsheng, a young technician in the CNC machining department of Nanjing Chenguang Group Co., Ltd., aerospace science and technology institute, researched a set of unique methods for automatic feeding of standard parts on CNC lathes. The method reduces the labor intensity of the ---MORE---
1 Introduction The polycrystalline diamond compact consists of a PCD layer and a cemented carbide substrate. The PCD layer has high hardness and the cemented carbide substrate has good toughness. The combination of the two makes the PCD composite sheet have excellent cutting performance, so it has ---MORE---
Such an arbitrary surface can naturally be dealt with, and it is also a perfectly reasonable practice, but when processing a regular surface such as a spherical surface, there are some problems in the process. Due to the limitation of the underlying mathematical model of the CAD/CAM software constr ---MORE---
