Vacuum sintering of helical milling insert blank
Welded helical milling cutters are used to process deep holes or special workpieces. The manufacturing method is to weld the thread milling cutter head to another tool. The transverse area of the helical milling insert blank is small, the longitudinal length is long, and there are edge relief ang...
Vacuum carburizing process of gear steel
Carburized steel usually refers to the steel used after vacuum carburizing, vacuum quenching and low temperature tempering. 20CrMnTi carburizing steel is a low-carbon alloy steel with excellent process performance. It is widely used in important carburizing parts with a cross-section less than 3...
Factors Affecting Vacuum Sintering of Alumina Ceramics
Among industrial special ceramics, Al2O3 products are widely used in chemical phosphate compound fertilizer, non-ferrous metal industry and other industries because of their excellent acid and alkali resistance, wear resistance, electrical resistance and high mechanical strength. In the producti...
Ingot bottom vacuum heat treatment
The spindle is one of the main components of twisting and winding on the spinning machine, and it is an assembly with a slender rotary shaft supported by two points as the main body. There are spindles on the roving frame, spinning frame and twisting frame. The roving spindle is a round steel rod...
CVD Diamond Tool Brazing
With the development trend of lightweight and high-strength workpiece materials, more stringent requirements are put forward for the tools used in material cutting. Diamond tools have the advantages of extremely high hardness and wear resistance, low friction coefficient, high elastic modulus, hi...
Waveguide Slot Antennas Vacuum Brazing
Waveguide slot antennas have been greatly developed since the middle of last century, and are widely used in various fields such as ground, shipboard, airborne, and navigation. Because the slot array antenna is easy to control the amplitude distribution in the antenna aperture plane, the apertur...
304 stainless steel sound-absorbing honeycomb vacuum brazing
The sound-absorbing honeycomb structure is composed of a perforated panel, a honeycomb core and a non-porous panel, which are connected by vacuum brazing or bonding. The sound-absorbing principle of the sound-absorbing honeycomb is mainly to use the sound wave to enter the Helmholtz resonant cavi...
Carbide Vacuum Brazing Process
Common process methods of vacuum brazing The main technological parameters of the vacuum brazing process are brazing temperature and holding time. The brazing temperature is usually selected to be 25-60°C higher than the liquidus temperature of the solder to ensure that the solder can fill the ga...
Vacuum brazing process of Ag-Cu eutectic solder
Copper and copper alloys usually have excellent electrical conductivity, thermal conductivity and excellent corrosion resistance in some media, and some copper alloys also have high strength, so they are used in electrical, chemical, oxygen, brewing, food, Industrial sectors such as power and tra...
Vacuum annealing process of steel ring
Textile equipment traveler is an easy-wearing part used in conjunction with steel rings on textile machinery. The main failure mode of steel ring and traveler is friction and wear, and the wear of machine parts mainly starts from the surface. Therefore, when the structural form and material are d...
