Material 42CrMo4 is one of the most extensive steels types for precision CNC machining

- Nov 22, 2019-

Precision CNC machining is still very important in the current work, and it is also very high in the development of technology. 

Nowadays, precision machining is still very much in terms of quantity every day, and now many precision CNC machining manufacturers are doing a comparison in this respect. 

Ok, that's why precision CNC machining is still so popular today.


And now the precision CNC machining performance is very stable, and it is also very complete in the category, and from these years of view, the technology of precision CNC machining is still very generous, why do you say that?


Main features: After quenching and tempering treatment, it has good comprehensive mechanical properties, low temperature impact toughness and low notch sensitivity, good hardenability, high fatigue strength when oil cooling, 

and easy to shape parts when water cooling Cracking, cold bending plasticity, good tempering or quenching and tempering, but poor weldability, easy to crack, preheated to 100 ~ 150 ° C before welding, 

generally used in quenched and tempered state, can also Carbonitriding and high frequency surface quenching treatment.


Application examples: After quenching and tempering, it is used to manufacture medium-speed and medium-load parts, such as: machine gears, shafts, worms, spline shafts, thimble sleeves, etc., which are used for manufacturing high hardness and resistance after quenching and tempering and high frequency surface quenching. Grinded parts, 

such as:  gears, shafts, spindles, crankshafts, spindles, sleeves, pins, connecting rods, screws and nuts, intake valves, etc., are used for heavy-duty and medium-speed impact after quenching and moderate temperature tempering. Parts, such as oil pump rotors, sliders, gears, spindles, collars, etc., 

After quenching and low temperature tempering, are used to manufacture heavy-duty, low-impact, wear-resistant parts such as worms, spindles, shafts, collars, etc., carbon Nitrogen co-infiltration is the manufacture of transmission parts with large dimensions and high temperature impact toughness, such as shafts and gears.
