I. Main Purpose of Machine Tool
This machine tool is used to cut large steel billets with a cutting height of ≤800mm and a width of ≤800mm, and it can also cut various ferrous or non-ferrous metal materials through selecting appropriate process parameters.
II. Main Features of Machine Tools
1. The machine tool has the functions of automatic clamping and automatic feeding through the combination of mechanical, electrical and hydraulic systems.
2. The feed speed of the machine tool can be adjusted steplessly within a given range.
3. The main moving parts - the lifting and lowering motion guide of the saw frame adopt high-precision rolling linear guide pairs with high movement accuracy.
4. The cutting tool adopts a thin bimetal band saw blade with narrow cut, less consumables and small power required, and it is a cutting device used to cut large steel billets and large mold blanks in the large and medium-sized enterprises and institutions with significant material saving and energy saving.
