3 Axis CNC-CP3-600/L Simple Control CNC Pipe Cutting Machine on Small Pipe

A. Applicable Workpieces and Application of CNC-CP3-600/L Models Simple 3 Axis CNC Pipe Cutting Machine:

1. The Model CNC-CP3-600/L CNC Pipe Cut Machine:

Refers to:

1) 3 axis CNC control, along pipe diameter/ length/ circumference;

2) The max. Φ600mm pipe diameter;

3) L of pipe length, usually up to 12m or longer;

2. Suitable Pipes:

CNC-CP3-600 models are specifically used on cutting small pipes:

1) Diameter: Φ80mm ~ Φ600mm;

2) Pipe Wall Thickness: 3mm ~ 15mm;

3) Cutting Kerf: Depending on diameter of pipe, and subsequent process technology, no need to cut out oblique rim, just straight edge cutting kerf is enough;

3.  Function of 3 Axis Simple CNC Pipe Cutting Machine:

1) With: Cut off pipes with certain designated length. For example, cut of a segment of 5m pipe, from the original 12m pipe;

2) Without: There is no 0°~ 360° revolve and tilt of cutting torch. So, the 3 axis model can not cut holes in longitudinal body of pipe, as in the case of 5 axis plus models;

3) Future Expansion: For this reason, the CNC controller of 3 axis model has software open control axis and hardware open connectors, in case of customers have future demand on function expansion into 5 axis, of cutting hole and slant edges:

4) The oval shaped hole with slant bevel, which needs to be cut with 5 CNC control axis: (Fig.1)

4. Development Background of Simple 3 Axis CNC Pipe Cut Machine:

1) Every model in the product family of CNC-CP series CNC Pipe Cutting Machine has its personality and significance, which was developed echoing certain market demand, and this is no difference to this “Basic configuration” model;

2) The First Model: In fact, the model of 3 Axis CNC-CP3-600 is the start point of the entire product family. As we know, each time development of new product always starts with the simplest type with the most compact dimension, which is this model represents;

3) As the earliest model developed in its early stage over 20 years ago, around year 2000, later on, with mature of both hardware and software technique, and growing of carbon steel pipe thermal cutting market, both control axis of CNC and size of workpiece pipe have gone thru increasement in the CNC Pipe Cutting Machine: From 3 Axis to 5 Axis/ 6 Axis/ 7 Axis, from Φ600mm to Φ1400mm/ Φ2000mm/ Φ3000mm models;

5.  Application: Nowadays in 2020s, the basic model of CNC-CP3-600 does not see extensive use. It is only used in those working sites of quick cut off small pipes without additional requirement. The model has more significance than practical use.

B. Operation Steps of CNC-CP3-600/L Simple 3 Axis CNC Pipe Cut Machine:

1. Pipe clamp claw fixture in 3 Axis 600/12 series is with chuck, which is adaptable on firmly fixing small diameter thin wall pipes without deformation:

1) Clamping small pipes into Wuxi JACK machine, with 3 jaw claw: (Fig.2)

2) Close view on 3 jaws chuck claw for pipe clamp: (Fig.3)

2. The 3 CNC Axis of 3 Axis CNC Pipe Cutting Machine:

This can be illustrated with below sketch: (Fig.4)

1) X Axis: Cutting torch can be adjusted along length direction of workpiece;

2) Y Axis: Workpiece pipe rotates 0° ~ 360°, so that cutting torch always directs at 12 o’clock position on the pipe, during the entire cutting operation in the machine;

3) Z Axis: Cutting torch can be moved up and down, so that be fitting for different diameters of workpiece pipe;

With the above 3 axis control, the machine cut off pipe into required length, without slant angle beveling function. Following that, it can be welded with flange, or fabricated into complicated pipe assembly;

3. General Basic Motions of Cutting Torch in 3 Axis CNC Pipe Cut Machine:

For fulfilling on pipe cutting task in 3 axis model, the cutting torch completes steps in sequence of:

1) Moving along longitudinal body of pipe, determining length of cut off segment: X axis;

2) Descends down to external wall of pipe, based on diameter of pipe, Z axis;

3) Start up thermal cutting, either Oxygen fuel or plasma, the pipe rotates 360° in adjustable cutting linear velocity, Y axis;

4. Applicable for Small Pipes: For the basic configuration of 3 Axis control model, the specification of Φ600mm is the most fitting model. Because usually the smaller the diameter, the smaller thickness of pipe wall, which means less need on oblique beveling function on pipes.

C. Mechanical Features of CNC-CP3-600/L 3 Axis Simple CNC Pipe Cut Machine:

1. Mechanical Main Frame of 3 Axis CNC Pipe Cutting Machine:

a) Feature: This machine has concise and open structure. A set of L shape stationary main frame constitutes main body of the machine, with upright side wall and long length base bed;

b) The mechanical main frame can be classified into 4 major sections of:

1) The upright side wall perpendicular with workshop floor and base bed, installed with chuck claw at its middle, serving as workpiece pipe end clamping unit;

2) The long length base bed is installed firmly into workshop floor. Depending on pipe length, there are 2 to 3 sets of “X” shape angle adjustable brackets, which can move along the length of entire base bed, holding pipe reliably along its entire lengthways body;

3) The pipe longitudinal direction moving carriage of cutting torch, which moves under motor drive, based on cutting point on pipe;

4) The high rise cable and cutting tubes sliding racks, cutting torch carriage is installed together with this rack;

2. Cutting Torch Movement in Basic Configuration3 Axis CNC Pipe Cutting Machine:

1) Cutting torch illustration in 3 axis model machine: (Fig.6)

2) Illustrated in the above sketch, the cutting torch for 3 Axis model machine has straight structure of vertical up and down movement, without revolve and swing functions.

D. When to Choose Basic Configuration 3 Axis CNC Pipe Cutting Machine?

1. For customers do not need edge beveling on their mall diameter pipes, this model of 3 Axis CNC-CP3-600/L is proper choice: It has inexpensive price, easy operation, short time installation and commissioning, as well as convenient maintenance;

2. Besides, due to the modular design of Wuxi JACK machine structure, and easy expansion on interface of CNC control system, including both hardware and software, this basic configuration 3 axis model machine is available for later on upgrade into 5 Axis and or 7 Axis control when necessary;

3. Advantages of 3 Axis Simple CNC Pipe Cutting Machine:

If it is does not need beveling or chamfering on pipe rim, the 2 most salient advantages with this 3 Axis model are:

1) Lower Investment on CNC Pipe Cut Machine Purchase:

a) Price Reduction: With all the other preconditions and specifications at same level, the quotation of 3 Axis version model machine is over USD10,000 lower than that of the 5 Axis counterpart;

b) Here “counterpart” refers to that, all the other specifications of machine on pipe cutting, for example, the max. pipe diameter, length, etc. are all in the same range. This is the model of 5 Axis 1400/12 CNC machine.;

c) Financial Benefit: Such price difference on 3 Axis versus 5 Axis models equals to around 10~ 15% less machine investment;

2) Easier Job in Operation of CNC Pipe Cutting Machine:

a) Advantage: The operation of 3 axis model is much simpler than that of the 5 Axis and 7 Axis models;

b) Strong Points: This means that, shorter period of operator training, shorter cycle time in daily work, and less risk of mal-operation and mal-function of the machine, on fulfilling task of CNC control pipe cutting;

c) Variable Cost Save: Combined together, all of these factors can greatly reduce period and variable running cost of machine;

d) Summing up, under the precondition of meeting customer demand, the 3 axis model machine is a very cost effective and tailor made version for customers.
