Gantry CNC Plasma Cutting Machine

Gantry CNC Plasma Cutting Machine


Mechanical Part

1.The frame is welded by 8mm steel plates;

2. The front beam is welded by 20mm steel plates. It’s finished by large gantry CNC milling machine at one time. It makes the surface flat and smooth, which ensures the higher cutting accuracy when the machine is running.

The beam adopts hollow welding process to facilitate the heat dissipation and prevent thermal deformation.

3. The rack groove and the guide groove are processed by large gantry milling machine at one time to ensure the parallelism and straightness of the machine and improve the operation accuracy.  

4. The longitudinal drive adopts bilateral drive with built-in Japanese Panasonic 750W motors, which makes the operation more stable. The use of non-clearance soft fitting device can effectively reduce the gear bite error, and also avoid excessive wear caused by iron chips entering the gear when the machine is running.

5. The horizontal transmission adopts Japanese Panasonic 400W servo motor to drive the main torch to move, and the main torch drives the auxiliary torch to move through the steel wire rope. This transmission mode has low failure rate and strong torsion resistance. The steel wire rope is easier to replace and maintain than the steel belt , and it will not excessively delay the customer's construction period. But it is not as high as the transmission accuracy of the steel belt.

6. The lifting body adopts an eccentric wheel-clamping device, which is not easy to be damaged, and it has low failure rate and the adjustment is convenient..


Electrical Part

1.The CNC control system generally includes Shanghai Jiaotong University, imported systems include Hypertherm and Boni.

2. The domestic plasma power source include Huayuan and YOMI; imported brands include Hypertherm, Lincoln, Kelbe.

Kelbey is better in the field of cutting small holes, and it has an advantage in price compared with Kaibo, which is also in the field of cutting small holes.

Thermadyne plasma power source ‘s water mist treatment technology has advantages in cutting stainless steel and other non-ferrous metals, avoiding oxidation and discoloration during cutting.

The unique water mist treatment technology of thermal-dynamics has advantages in cutting stainless steel and other non-ferrous metals, and avoid the oxidation discoloration during cutting.  

3.The arc voltage height adjustment (THC) is made by Shenzhen HongyuDa, which has high control accuracy, stable performance and strong anti-interference ability. It can always keep the distance between cutting torch and plate to prevent the torch from knocking plate.

4.The Wires and cables are made in Shanghai Cardiff, with good toughness and not easy to break.

5. The electrical components are made of French Schneider, with stable performance and long service life

6. The gas hose is made of South Korean Samsan, which is resistant to high temperature, high pressure and cold.

7. The solenoid valve is made of Taiwan AirTAC, which has high temperature resistance, stability and good sealing performance.

8. The flame cutting torch is made of Wuxi Longteng, equipped with automatic ignition device and anti-backfire device, with higher safety.

9. The reducer is made of Newstar, with high reliability, compact structure and light weight.
