CNC-CG6000 To CNC-CG10000 Large Span CNC Shape Cutting Machine

A. Scope and Operation Feature of Flame Plasma Large CNC Cutting Machine:

1. Percentage of Conventional Versus Large Models CNC Shape Cutting Machine:

1) Majority: In the application field of flame plasma CNC Shape Cutting Machine, most majority models (Over 80%) fall within scope of 3,000mm cutting rail span (CNC-CG3000) to 5,000mm cutting rail span (CNC-CG5000), especially CNC-CG4000, the single model account for around 50% of actual use;

2) Large Cutting Rail Span Models:

When cutting rails span reaches and exceeds 6,000mm (CNC-CG6000), the machine can be viewed as large span models, which, although in small percentage use, has its irreplaceable position, on the aspect of:

a) Application;

b) Mechanical frame structure;

c) Cutting rails;

d) Configuration;

2. Scope and Operation Features of Large Flame Plasma CNC Profile Cutting Machine:

1) Currently, the recommended Large CNC Flame Plasma Cutting Machine is from CNC-CG6000 to CNC-CG10000:

2) Operation Features of Flame Plasma Large CNC Cutting Machine:

a) Large models machines are basically applied for shape cutting, or called profile cutting, and flame triple cutting. As can be observed from the above photos, there is seldom strip cutting torches to be equipped in these large machines:

b) Shape cutting on carbon steel plates, with Wuxi JACK Large CNC Cutting Machine: (Fig.3)

c) Wuxi JACK CNC-CG6000 model Oxygen fuel Large CNC Cutting Machine, equipped with 3 groups of triple cutting torches: (Fig.4)

B. Usage and Great Value of Large Flame Plasma CNC Profile Cutting Machine:

1. Function: CNC machine realizes automatic cutting on metal plate in batches, making consistent and uniform delivery of workpieces with whatever required quantity. Together with Press Brake and Shearing Machine, these three machines are the basic and requisite equipment in modern manufacturing facilities;

2. Put into Use: Flame Plasma Large CNC Cutting Machine is used for plate profile cutting of large width carbon steel plates (Wider than 5,000mm), or two pieces of narrow plates at the same time. As you can find from below photo, there are two sets of cutting platforms under mechanical main frame of machine:

In Wuxi JACK CNC-CG8000 model large span machine, there are 2 sets of cutting table, and 2 pieces of steel plate can be cut simultaneously: (Fig.5)

3. Double Drive: Here we emphasize again that for machine cutting rail span equals to and wider than 4,000mm, double drive is a must for its normal running and eligible work;

4. Operation: The management on cutting operation is accomplished with buttons and switches on the yellow panel; The cutting program is edited and enforced with the CNC controller:

5. Benefits of Flame Plasma Large CNC Cutting Machine for Customers:

1) Cutting Super Large Integral piece of Steel Plate:

Some industries involve processing of steel plates with excessive width. For example, Shipbuilding, Port Machinery, Bay Bridge, etc.;

2) Saving Steel Plates Handling Cycle Time:

To save loading/ unloading time of metal plates into and out of machine, customers expect to cut two pieces of standard size (Three to four meters width) metal plates at the same time in one batch;

3) Cutting Several Pieces of Short Length Steel Plates in a Row:

When the raw material of steel plates have length at around the same size as valid cutting width of machine, for example, for CNC-CG8000 model Large CNC Flame Plasma Cutting Machine, of 8,000mm cutting rail span, 7,200mm length of steel plates, lay several pieces of such carbon steel plates in 90° turning positioning on machine cutting table, and cut the steel plates with one time machine operation, thus saving more supporting time: Load/ Unload/ Call Program of machine.
