Comparison of Thick plate welding machine bed and Iron casting bed

Many customers are confused about iron cast bed and heavy plate welding bed,which is better?


First of all, let us learn about cast iron bed processing:

Large-scale machine tool bed casting is a process in which metal is smelted into a liquid that meets certain requirements and poured into a mold.

After cooling, solidification and cleaning, A casting with a predetermined shape, size and performance is obtained.

The casting of large machine tool bed is one of the basic processes of the modern machinery manufacturing industry.

So what reason may affect iron cast machine bed quality?

During the casting process,it is inevitable create some air bubbles and pores,that will reduce the compactness of the castings, causing some castings that are required to withstand the hydraulic test to be scrapped.

In addition, pores also have an adverse effect on the corrosion resistance and heat resistance of the casting.

These bubbles will make bed not solid. After long time running. Machine bed may breakage after long time running.

During the pouring process of large-scale machine tool bed castings, if the casting is insufficient, the castings will not be able to obtain a complete shape; during cold isolation, although the bed castings can obtain a complete shape, due to the existence of incompletely fused seams, the mechanical properties are severely damaged.

There also have a point could effect cast iron bed quality:

For some current factories who produce machine beds,most of them choose some mixed, low quality irons, as a result, machine quality can not be assured.

We found that in the market, total weight of iron casting machine bed is no heavier than 3 tons, which is absolutely terrible.

Because manufacturers want to make more profits, so some of them use less materials.

(Tips:One standard 1530 iron casting machine bed should at least 4-5 tons)

All in all, some suppliers only use IRON CASTING MACHINE BED for an advertisement.

After machine bed finished ,we need to drill and fix guide rail,rack,,, transmission structure.once the screws on machine bed are loose, that will be hard to fix it.

During fiber laser cutting machine running processing, the machine bed will vibrate, after a period of time, is will have big problems.

XTLASER adopt heavy plate welding machine bed:

This kind of machine bed has strongly reasonable structure, it is produced by relief annealing, so the whole structure is  firm and hard to be deformed.

For thick plate welding machine bed, inside the metal plates are solid. So, even after long time of running, it will still remain stable.

After long time of using , some screws may become loose, but do not worry. Because you just make screws more tight, that is all.
