Main Structure of the Machine Tool 

6.1    Deceleration Worm Gear Box Part

 

    The part of the deceleration worm gear box lies beneath the frame. The linear speed of 
the saw band is changed by the transmission band wheel which is triggered by the main 
engine transmission band wheel.

 

6.2    Frame Part

 

The saw frame part is a welding combination of the iron plates, supporting the feeding 

wheel, passive wheel and the transmission part of the saw band.

 

6.3    Machine Body

 

The machine body is a box-shaped welding part with a cooling water tank on the right 

and a hydraulic oil tank on the left. There are four corresponding suspending loops in the 
front and in the back of the body respectively, applied for lifting and moving. And there are 
six tapped holes beneath for fastening the machine tool

 

6.4    Working Table

 

      The  working  table  is  equipped  with  the  jaw  and  the  hydraulic  cylinder  used  for 
clamping working parts. The working table supports the cutting parts to finish the cutting.
