Vacuum brazing process
Vacuum brazing production technology is the technical software to make the super hard abrasive brazing tools. There are six processes including product preparation, pre-processing, sanding and powdering, firing, post-processing and packaging and storage. Product preparation process Product prepar...
diamond cutting tools manufacture
This paper introduces the design and manufacture of diamond tools and some latest achievements of diamond tools. This paper expounds the development trend of modularization and cheapness from the perspective of popularization and application, and puts forward some new ideas and methods on how to ...
vacuum heat treatment
As a green environmental protection technology, vacuum heat treatment has many advantages after years of development, especially the wide application of high-pressure gas quenching furnace Pollution-free; Large amount of primary charging; Energy saving; Less and no oxidation and decarbonization; ...
vacuum heat treatment technology advantages
Vacuum heat treatment is a metal heat treatment process in which the metal workpiece is heated below 1 atmosphere (that is, under negative pressure). The anaerobic heat treatment of vacuum heat treatment can avoid the oxidation and decarburization of the workpiece, greatly improve its hardness a...
Hardness of quenched workpiece
The relationship between the hardness of the quenched workpiece and the quenching effect The hardness of the quenched workpiece is directly proportional to the quenching effect. In other words, the stronger the hardness of the quenched workpiece is, the harder the quenching effect is to grasp. Th...
Quenching heat treatment of workpiece
The cause of the uneven hardness in quenching heat treatment of workpieces In order to meet the requirements of mechanical properties of products, more than 90% of steel manufacturers will heat treat them, most of which need to be tempered, such as drill pipe joints, directional joints, screw dri...
Heat treatment quenching oil
Classification, performance characteristics and application scope of heat treatment quenching oil Heat treatment oil is a kind of treatment oil with strong cooling performance and good oxidation stability. It can be divided into ordinary quenching oil and fast quenching oil. Quenching oil is a ki...
Quenching hardness of workpiece
The main factors causing the uneven hardness of the workpiece In the process of quenching, due to the different flow speed of the quenching cooling medium around the workpiece, and even the formation of “dead angle” of the liquid flow in some parts, the cooling speed of different part...
Vacuum heat treatment of precision die
How to prevent heat treatment deformation of precision die As we all know, during the vacuum heat treatment, especially in the process of vacuum quenching, due to the temperature difference caused by the different heating and cooling speed of each part of the die cross section, as well as the une...
vacuum brazing furnace welding effect
The brazing method in vacuum furnace is a new one without flux under vacuum condition. Because the brazing is in the vacuum environment, it can effectively eliminate the harmful effect of air on the workpiece, so it can be successfully brazed without applying flux. It is mainly used to braze meta...
