• HK-72T Three-dimensional 3D oxy-fuel cutting machine with flexible track
  • Model Name:

    HK-72T Three-dimensional 3D oxy-fuel cutting machine with flexible track

  • Product Description
  • HK-72T is a portable automatic cutting machine which is specially designed for cutting on the three dimensional structure (especially for three dimensional curve) to ensure high precision. There are three rails of 1D, 2D and 3D, which can increase operation range and rationality, but also can decrease cutting workload.


Follow Us:



1. Handle: Catch the handle when you carry machine.

10. Thermal baffle: To prevent the heat diffusing into the inner of machine.

2. Switch: When it is set on arrow direction, the machine starts to walk towards to this direction.

11. torch  

12. groove cutting screw

3. Speed controller: Increase the speed if it is rotated clockwise.

13. Torch lifting knob: It is used to adjust the vertical position of torch.

4. Control panel: Switch and speed controller is used to control machine.

14. Rubber track: There are three types: 1D――straight AL track; 2D――two-dimensional cutting track; 3D-- three-dimensional cutting track. Choose suitable track according to the sharp of work.

5. Host machine 

6. Clutch rod: When it is on right, the clutch is OFF. When it is on left, the clutch is ON.

15. Torch sliding knob: To adjust the horizontal position.

16. Hose: Connect them between distributor and torch. The three hoses are used individually for fuel gas (red), preheating oxygen (blue) and cutting oxygen (blue).

7. Control rod: Use it to assemble or demount track.

8. Magnet: It fixes the track to steel plate. Use control rod to make magnet be on or off.


18. Gas distributor: It is used to control the flow of preheating oxygen, fuel gas and cutting oxygen to reach best flame.

9. Sliding roller wheel: The wheel and track are used to keep machine stable.
