1. Usage: CNC Plasma Cutting Machine cuts out sheet metal into finished workpieces of various outline, in high speed and with perfect accuracy:
2. Position: CNC Plasma Cutting Machine was developed on the basis of Flame CNC Plate Cutting Machine. This CNC Plasma Cutter is medium and high end product of flame plasma CNC Cutting Machine, bridging the gap between flame cutting and laser cutting in terms of cost/ roughness, and cutting speed;
1) Available on Cutting All Kinds of Metal Materials: CNC Plasma Cutter is not confined to cut on carbon steel. Instead, plasma CNC Cutting Machine can also be applied to cut on sheet metal of Stainless Steel/ Alloy/ Al/ Bronze ...;
2) With Obviously Higher Cutting Speed than Flame CNC Cutting Machine: The 3000~ 5000 mm/min. cutting velocity of CNC Plasma Cutting Machine can deliver 3~5 times higher productivity compared with Flame CNC Plate Cutting Machine, when cutting on same thickness range of sheet metal;
3) Gloss and Deformation Control on Cutting Kerf: Smaller heat affect area around cutting point of CNC Plasma Cutter, guarantees much smaller deformation of finished product, and nearly no slag effect of cutting kerf. This promises high quality cut out working part delivered from CNC Plasma Cutting Machine;
4) Flexible and the Most Fitting Mechanical Structure: Besides conventional moving gantry frame of CNC Plasma Cutter, CNC Plasma Cutting Machine can also be designed and manufactured into compact stationary table structure for fulfilling high precision cutting performance; Or in the form of underwater CNC Plasma Cutter, to acquire environmental friendly running of CNC Plasma Cutting Machine:
a) In Flame CNC Plate Cutting Machine, there are 3 ways of cutting gas deployment: Preheating Oxygen fuel; Cutting Oxygen fuel; Cutting Acetylene/ Propane, which need to be arranged in both lengthways and transverse direction of over 20m distance along the entire working zone of flame CNC Cutting Machine;
b) Comparatively, CNC Plasma Cutting Machine only involves short distance cable routing from plasma power supply to cutting torch, which is usually within the scope of 5m at the most.
1. Applicable Sites: Benefitting from the above listed strong points, CNC Plasma Cutting Machine is usually used for “High End” use of shape cutting, in the applicating sites with strict demand, such as: Shell processing on mechanical and electric products/ advertising logo/ craft decoration, etc.
2. Extended to Drilling Function: Some customers require CNC Plasma Cutter also with mechanical drilling ability, especially for Steel Structure use. To meet this demand, Wuxi JACK successfully develops integrated function CNC Plate Cutting Machine, making it into a set of “CNC Plate Drilling and Cutting Machine”:
1. Cutting Tool and Principle: CNC Plasma Cutting Machine adopts high speed ionized compressed air as its cutting media, which radiate high temperature electric arc during cutting, and in turn melt metal plate instantaneously, so as to efficiently and precisely generate cutting kerf with CNC Plasma Cutter;
3. Quick and overall review on product family of Flame and Plasma CNC Cutting Machine, is illustrated in summary slides web page: “Overview on Wuxi JACK CNC Plate Cutting Machine”.

Check List on Production Procedure of Plasma CNC Plate Cutting Machine:
1) Why Need: In practical use, many sheet metal plates have uneven surface, especially those with large size and with small to medium thickness. This will produce changing gap between CNC Plasma Cutter cutting tip and surface of sheet metal, which brings along negative impact on cutting quality of CNC Plasma Cutting Machine;
2) Proper Type: To maintain constant distance between CNC Plasma Cutter cutting torch tip and sheet metal, the plasma cutting torch of CNC Plate Cutting Machine should be equipped with cutting torch height controller. For CNC Plasma Cutting Machine, the cutting torch height controller is arc voltage type.
1) Significance: This is of vital importance for managing on stable/ smooth and accurate performance of cutting torch in CNC Plasma Cutting Machine, not only its movement along X axis of transverse direction, but also Y axis of longitudinal direction;
2) Advantages: Linear guiderail has light deadweight and little inertia, which guarantees accurate and precise guiding of cutting torch during operation of the CNC Plate Cutting Machine, even cutting around sharp corner of sheet metal.
1) Lateral linearity of main rail is 0.3mm/ 1000mm;
2) Lateral linearity of supporting rail is 0.8mm/ 1000mm;
3) Levelness of rail surface in CNC Plasma Cutter is ±0.18mm/ 1000mm;
4) Positioning Accuracy of plasma CNC Plate Cutting Machine is ±0.25mm.
The four most critical units for guaranteeing successful running of plasma CNC Plate Cutting Machine include:
1) CNC controller;
2) Servo drivers and driving motors;
3) Plasma power supply;
4) Cutting torch and its IHS (Initial height sensor).
The mechanical box structure of Wuxi JACK CNC Plasma Cutting Machine is of integral fabricated style, which is stress relieved thru advanced heat treatment. It has light deadweight and high strength.
1) CNC-CG series CNC Cutting Machine is in the form of “Modularization”: Basic skeleton and function units, plus various optional configurations;
2) CNC Plasma Cutter has same structure as flame CNC Plate Cutting Machine, and can have functions integrated together. So, people sometimes call it Flame CNC Plasma Cutter;
3) Comparatively, laser CNC Cutting Machine differs from flame and plasma CNC Plate Cutting Machine, in view of structure and function group;
Understanding how does a set of CNC Plasma Cutting Machine come into being, we can find its three common seen applicating forms as below:
1) The above 1st Photo: There is only plasma cutting system being equipped with CNC Cutting Machine;
2) In practical application, such solitary plasma cutting configuration account for minority use of CNC Plasma Cutter;
3) Applicable For: Sole function plasma CNC Cutting Machine is applicable for working site of cutting non-ferrous metal, in small to medium thickness, requirement of shape cutting only;
1) The above 2nd Photo: There are both plasma and flame cutting torches and systems, in one set of Flame CNC Plasma Cutter CNC Cutting Machine. The plasma cutting torch and flame cutting torch can share the same set of moving carriage, as shown in the flame plasma CNC Plate Cutting Machine of the 2nd photo, which saves manufacture cost;
2) Or, the two pieces of cutting torches are installed individually onto separate moving carriages, which adds on total cost of the Flame CNC Plasma Cutter CNC Cutting Machine;
3) In practical application, such configuration has more application in CNC Plasma Cutter CNC Cutting Machine than sole purpose plasma cutting;
4) It is applicable for working site of cutting both ferrous and non-ferrous sheet metal, covering whole range of plate thickness;
1) The above 3rd Photo: Such solution is the most cost effective design of Flame CNC Plasma Cutter CNC Cutting Machine, and also the most popular choice by customers;
2) Flame plasma CNC and strip CNC Plasma Cutting Machine takes the largest share in practical application, which can meet all the cutting requirement of customers.
The components/ parts/ elements, and assemblies that are assembled into a set of Flame CNC Plasma Cutter CNC Cutting Machine can be divided into below 4 major groups of:
1) Mechanical Main Frame: As shown in the above photos: Main Frame is a complex of motor drive moving gantry, with cross section in the shape of inverted “T” box structure. Both sides of the gantry are installed with 750W servo motor, this come into being “double drive” of the Plasma CNC Cutting Machine, and guarantees smooth/ stable/ precise cutting procedure of CNC Cutting Machine;
2) Horizontal Way X Axis: During plasma and flame cutting, the cutting torches move along horizontal beam of the gantry, carrying out X axis movement of cutting torches in the Flame CNC Plasma Cutter CNC Cutting Machine;
3) Longitudinal Way Y Axis: The bottom surface of gantry is installed with guide wheels, guiding the gantry moving along longitudinal rail of CNC Plasma Cutter, carrying out Y axis displacement of cutting torch in the CNC Plasma Cutting Machine;
Based on structure of mechanical frame, CNC Plasma Cutting Machine can be grouped into 3 types of moving Gantry frame, stationary Table type, and Underwater:
1) This takes over 90% of the CNC Plasma Cutting Machine. The common seen models are CNC-CG4000, and CNC-CG5000;
2) For 4,000mm span CNC Plasma Cutter (CNC-CG4000), because of its wide use, there are 2 options of: Plasma only CNC-CG4000 CNC Plasma Cutting Machine, and CNC-CG4000 flame plasma CNC Plate Cutting Machine;
1) This approaches to laser cutting in terms of workpiece piece and cutting outcome:
2) Such “high end” CNC Plasma Cutter CNC Cutting Machine is adopted with fine plasma cutting, for cutting on thin stainless steel/ Al/ Alloy material small size sheet metal;
1) This is for the purpose of getting environmental friendly operation: Fumes and lights generated are absorbed into water table;
2) The cutting capacity (Thickness and cutting speed) of underwater CNC Plate Cutting Machine is compromised 15% compared with dry type CNC Plasma Cutter.
