What are some skills of daily use of CNC cutting machine? Here, Shandong automatic welding equipment manufacturer summarizes some skills of daily use of some CNC cutting machines, and hopes to give you some help.

1、切割應從邊緣開始;盡可能從邊緣開始切割，而不要穿孔切割。采用邊緣作為起始點會延長消耗件的壽命，正確的方法是將噴嘴直接對準工件邊緣后再啟動等離子弧。

1. Cutting shall start from the edge; Cut from the edge as far as possible, not through the hole. Using the edge as the starting point will prolong the service life of the consumable. The correct method is to directly align the nozzle with the edge of the workpiece and then start the plasma arc.

2、減少不必要的“起弧(或導弧)”時間;起弧時噴嘴和電極的消耗都非常快，在開始前，應將割炬放在切割金屬行走距離內。

2. Reduce unnecessary "arc striking (or arc striking)" time; The consumption of nozzle and electrode is very fast during arc starting. Before starting, the cutting torch should be placed within the walking distance of cutting metal.

3、噴嘴不要過載使用;讓噴嘴過載(即超過噴嘴的工作電流)，將使噴嘴很快損壞。電流強度應為噴嘴的工作電流的95%為宜。例如:100A的噴嘴的電流強度應設定為95A。

3. Do not overload the nozzle; Overloading the nozzle (i.e. exceeding the working current of the nozzle) will damage the nozzle quickly. The current intensity should be 95% of the working current of the nozzle. For example, the current intensity of a nozzle of 100A should be set to 95A.

4、采用合理的切距;按照使用說明書的要求，采用合理的切距，切距即切割噴嘴與工件表面的距離，當穿孔時，盡量采用正常切距的2倍距離或采用等離子弧所能傳遞的大高度。

4. Adopt reasonable cutting distance; According to the requirements of the operation manual, a reasonable cutting distance shall be adopted. The cutting distance is the distance between the cutting nozzle and the workpiece surface. In case of perforation, the distance twice the normal cutting distance or the large height that can be transferred by the plasma arc shall be used as much as possible.

5、穿孔厚度應在機器系統的允許范圍內;切割機不能在超過工作厚度的鋼板上穿孔，通常的穿孔厚度為正常切割厚度的1/2。

5. The perforation thickness shall be within the allowable range of the machine system; The cutting machine shall not perforate the steel plate exceeding the working thickness, and the normal piercing thickness is 1 / 2 of the normal cutting thickness.

6、盡量保持數控切割機割炬和消耗件清潔:在割炬和消耗件上的任何臟物都會大地影響等離子系統的功能。更換消耗件時要將其放在干凈的絨布上，要經常檢查割炬的連接羅紋，用過氧化氫類清潔劑清洗電極接觸面和噴嘴。

6. Try to keep the cutting torch and consumable parts of the CNC cutting machine clean: any dirt on the cutting torch and consumable parts will greatly affect the function of the plasma system. When replacing consumable parts, put them on clean flannelette, check the connecting rib of cutting torch frequently, and clean the electrode contact surface and nozzle with hydrogen peroxide cleaner.

7、盡量少穿孔切割，穿孔是鋼水反濺會傷及噴嘴，這是割嘴損壞的主要原因之一，如果一定要穿孔切割，在穿孔處用鉆頭打預鉆孔，在從預鉆孔處開始切割;

7. Try to cut as few holes as possible. Perforation is one of the main reasons for the damage of the cutting nozzle. If it is necessary to cut through holes, use a drill bit to drill holes at the hole and cut from the pre drilled hole;

8、盡量在切割機額定的正常切割厚度范圍內切割，盡量不要在極限切割厚度上切割，國產切割機的正常切割厚度一般是生產廠家標注的大切割厚度的60%，盡量在這個厚度范圍內切割，就能保護割嘴;

8. Try to cut within the rated normal cutting thickness of the cutting machine, and try not to cut at the limit cutting thickness. The normal cutting thickness of the domestic cutting machine is generally 60% of the large cutting thickness marked by the manufacturer, and try to cut within this thickness range to protect the cutting nozzle;

9、割嘴到鋼板的距離盡量保持恒定，一般在3-8mm左右，太遠了不但耗電量太大，切割穿透能力力會下降，而且相對比較消耗電極，使電極使用壽命下降;太近了那更簡單，非常費噴嘴，噴嘴的使用壽命會成倍的下降，甚與上去即被燒掉。

9. The distance between the cutting nozzle and the steel plate shall be kept as constant as possible, generally about 3-8mm. If it is too far, not only will the power consumption be too large, the cutting penetration capacity will be reduced, but also the electrode will be relatively consumed, which will reduce the service life of the electrode; It's much simpler if it's too close. It's very expensive for the nozzle. The service life of the nozzle will be doubled and even burned up.
