3-Axis 3000/12 Flame And Plasma Large Scale CNC Pipe Cutting Machine

A. Usage and Specialty of 3 Axis 3000/12 Large Size Plasma Oxygen Fuel CNC Pipe Cutting Machine:

1. The 3 Axis 3000/12 Flame and Plasma Large Size CNC Pipe Intersection Cutting Machine is “the simplest and largest” standard model, among all products of CNC-CP series machine;

2. Main Specification of 3 Axis Large Size CNC Pipe Cutting Machine:

The overall size of workpiece pipes in this model is same as 5 Axis 3000/12 and 7 Axis 3000/12 large type:

1) Diameter of pipes is up to Φ3000mm;

2)  The longest Length of pipes can be 12m;

3)  Wall thickness of pipes can be 100mm for flame cutting, and 25~50mm for plasma cutting;

4) Cutting torch work motion in 3 Axis 3000/12 model machine:  (Fig.1)

3. Control Axis of 3 Axis Large Size CNC Pipe Cutting Machine: 

Shown in the above sketch, in all the sizes of 3 Axis model, be it small size/ medium size/ or large size, the cutting torch moves up and down along axial direction of pipes, forward and backward along longitudinal direction of pipes, without swing for making beveling.

B. Characteristics of 3 Axis 3000/12 Large Size CNC Pipe Intersection Cutting Machine:

1. Friction roller support on large diameter pipes:  (Fig.2)

Shown in the attached 6^th photo and above photo, in large size CNC Pipe Cutting Machine, workpieces are laid on the array of supporting turning rollers;

2. What does “Simple” Mean for 3 Axis 3000/12 Large Size CNC Pipe Intersection Cutting Machine?

1)  Here the “Simple” means less control axis compared with 5 Axis and 7 Axis models;

2) Removing below control axis from 7 Axis CNC Pipe Cutting Machine:

a)  Cutting torch swing along axial and radial direction of the pipe;

b) Cutting torch movement along radial direction of the pipe;

c) As well as adjustment on span of turning rolls supporting the pipe;

3) The 3 axis CNC machine keeps control on pipe rotation, cutting torch up and down, and its movement along axial direction of the pipe;

4) In this way, the 3 axis machine retains the basic job of pipe cutting off in required length, cutting hole in the pipe with straight edge, as shown in the attached photos;

3. When to Choose 3 Axis, 5 Axis and 7 Axis CNC Pipe Intersection Cutting Machine?

1) The choice among 3 axis, 5 axis and 7 axis usually originated out of the demand on cutting kerf on pipe or not: whether it need to be finished together with the whole pipe cutting or not;

2) 7 axis CNC machine has basic same function as the 5 axis model, but with more delicate control on movement of turning rollers;

3) Usually, the pipes cut with 3 axis CNC machine has thinner thickness. Because thin thickness of pipes are difficult to have beveling, and usually not necessary.
