Vacuum heat treatment of high-speed turning tools
1.High-speed turning tool A turning tool is a tool that is used for turning operations and has a cutting portion. The working part of the turning tool is the part that generates and processes chips, including the cutting edge, the structure that breaks or rolls up the chips, the space for chip re...
Which process should be used for quenching after vacuum carburizing?
Vacuum carburizing and quenching is widely used in power transmission and fuel system components of automobiles, transmission components of trucks and off-road vehicles such as gear sleeves, pinions, etc., transmission and power system components of aviation and spacecraft, and other components s...
Improvement of Soft Magnetic Properties of FeCo Alloys by Vacuum Heat Treatment
FeCo soft magnetic alloys can reduce the weight and size of magnetic cores in various devices due to their high saturation magnetic induction. Promoting the miniaturization and weight reduction of devices has long received great attention in defense industries such as aerospace and nuclear indust...
Vacuum Sintering of Alumina Ceramics
In a modern society where science, technology and material civilization are highly developed, the materials that human beings rely on to make various industrial products vary widely, but in general, there are no three categories of non-metals, organic substances and ceramics. Alumina ceramics is ...
Metal injection molding vacuum sintering furnace
With the latest iPhones, small high-performance car engines, gearboxes or other machinery, there is a demand for system miniaturization, and the public is looking forward to more economical production techniques. Specifically, in notebook computers and mobile phones, many precision parts are used...
Vacuum Heat Treatment of 42CrMo Steel High Strength Bolts
1.Materials and Methods (1) Materials The raw material is φ40mm double vacuum smelting steel bar produced by a steel plant (2) Method The processing process of high-strength bolts is to roughen the φ40mm bar → stamping → necking → vacuum annealing → tapping → vacuum quenching → vacuum tempering →...
Deformation and Improvement of Slicing Knife Vacuum Quenching
Slicing knives are a type of cutting utility knife and therefore require good hardness and a straight profile. For many years, the conventional heat treatment and quenching process specification has been adopted. The warpage and deformation of the hot rear end face are large, and the defective pr...
Vacuum heat treatment process of steel bearing parts
High temperature bearing is a kind of bearing that can withstand high temperature, which is widely used in metallurgy, kiln, glass, blast furnace, painting equipment and other high temperature operation machinery. This type of bearing must undergo a good heat treatment process, and its strength c...
MIM plastic-based adhesive, wax-based which type is better?
1.Mixing stage The wax-based binder is mainly paraffin, with low viscosity and easy volatilization; therefore, it is easy to mix, but it should be noted that the temperature should not be too high (below 120 ℃), and it has an air-tight design to reduce volatilization loss. The plastic-based bind...
Vacuum heat treatment process of rolling die
The thread rolling die, also known as the rolling wheel, is used to thread the workpiece on the thread rolling machine. The most important characteristics in selecting a rolling die material are the hardness, toughness and wear resistance of the die steel. There must be sufficient hardness and to...
