Why engraving machine needs tempered cast iron bed
Why engraving machine needs tempered cast iron bed
The need for processing high-strength and high-precision engraving machine need to use cast iron bed, that engraving machine castings Why do we need tempering: steel machinery industry, the most widely used materials, iron and steel complex microstructures can be controlled by heat treatment Therefore, the heat treatment of steel is the main content of metal heat treatment. To make the casting machine has the required mechanical properties, physical properties and chemical properties, in addition to a reasonable selection of materials and various forming processes, the heat treatment process is essential. Further, aluminum, copper, magnesium, titanium and their alloys can also be changed by the heat treatment the mechanical, physical and chemical properties, to achieve different performance. Overall heat treatment is cast iron plate, iron bending machine bed castings or overall heating and cooling at the appropriate speed to change the cast iron platform, the overall mechanical properties of the plate, iron plate bending machine bed castings or metal heat treatment process. 
Machine bed casting products as a large castings must go through in order to improve the performance of aging itself, improve the intrinsic quality of the casting bed. Casting machine bed, bed column, the overall heat treatment machine table castings roughly annealing, normalizing, quenching and tempering four basic processes. Casting machine bed should strictly abide by tempering tempering process, or easily deformed ribs intensive parts should be added strut to prevent tempering temperature should lead to deformation and fracture. Back to the stove thermometer should be supervised and timely control the temperature, to prevent the temperature is too high or too low, this will have a great impact tempering workpieces.
