数控切割机在切割能源和数控控制系统两方面取得了长足的发展，切割能源已由单一的火焰能源切割发展为多种能源切割方式，下面为大家总结了一些数控切割机日常使用的一些技巧。

CNC cutting machine has made great progress in cutting energy and CNC control system. Cutting energy has developed from a single flame energy cutting to a variety of energy cutting methods. Here are some skills of daily use of CNC cutting machine.

1、切割应从边缘开始;尽可能从边缘开始切割，而不要穿孔切割。采用边缘作为起始点会延长消耗件的寿命，正确的方法是将喷嘴直接对准工件边缘后再启动等离子弧。

1. Cutting shall start from the edge; As far as possible, cut from the edge rather than through the hole. Using the edge as the starting point will prolong the service life of the consumer. The correct method is to align the nozzle directly with the edge of the workpiece and then start the plasma arc.

2、减少不必要的“起弧(或导弧)”时间;起弧时喷嘴和电极的消耗都非常快，在开始前，应将割炬放在切割金属行走距离内。

2. Reduce unnecessary "arc striking (or arc guiding)" 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、喷嘴不要过载使用;让喷嘴过载(即超过喷嘴的工作电流)，将使喷嘴很快损坏。电流强度应为喷嘴的工作电流的95%为宜。例如:100A的喷嘴的电流强度应设定为95A。

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

4、采用合理的切距;按照使用说明书的要求，采用合理的切距，切距即切割喷嘴与工件表面的距离，当穿孔时，尽量采用正常切距的2倍距离或采用等离子弧所能传递的大高度。

4. Adopt reasonable tangent distance; According to the requirements of the instruction manual, adopt a reasonable cutting distance, which is the distance between the cutting nozzle and the workpiece surface. When punching, try to use a distance twice the normal cutting distance or a large height that can be transferred by the plasma arc.

5、穿孔厚度应在机器系统的允许范围内;切割机不能在超过工作厚度的钢板上穿孔，通常的穿孔厚度为正常切割厚度的1/2。

5. The perforation thickness should be within the allowable range of the machine system; The cutting machine cannot punch on the steel plate that exceeds the working thickness, and the usual perforation thickness is 1/2 of the normal cutting thickness.

6、尽量保持数控切割机割炬和消耗件清洁:在割炬和消耗件上的任何脏物都会极大地影响等离子系统的功能。更换消耗件时要将其放在干净的绒布上，要经常检查割炬的连接罗纹，用过氧化氢类清洁剂清洗电极接触面和喷嘴。

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

7、尽量少穿孔切割，穿孔是钢水反溅会伤及喷嘴，这是割嘴损坏的主要原因之一，如果一定要穿孔切割，在穿孔处用钻头打预钻孔，在从预钻孔处开始切割;

7. Try to minimize perforation and cutting. Perforation is one of the main reasons for the damage of the cutting nozzle because the back splashing of molten steel will damage the nozzle. If perforation and cutting are necessary, pre drill the hole with a drill at the perforation and cut from the pre drill;

8、尽量在切割机额定的正常切割厚度范围内切割，尽量不要在极限切割厚度上切割，国产切割机的正常切割厚度一般是生产厂家标注的大切割厚度的60%，尽量在这个厚度范围内切割，就能保护割嘴;

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 domestic cutting machines is generally 60% of the large cutting thickness marked by the manufacturer, and try to cut within this thickness range, so as to protect the cutting nozzle;

9、山东数控焊接设备厂家认为割嘴到钢板的距离尽量保持恒定，一般在3-8mm左右，太远了不但耗电量太大，切割穿透能力力会下降，而且相对比较消耗电极，使电极使用寿命下降;太近了那更简单，非常费喷嘴，喷嘴的使用寿命会成倍的下降，甚与上去即被烧掉。

9. Shandong CNC welding equipment manufacturers believe that the distance between the cutting nozzle and the steel plate should be kept as constant as possible, generally about 3-8mm. If it is too far away, not only the power consumption is too large, the cutting penetration capacity will decline, but also the electrode is relatively consumed, which will reduce the service life of the electrode; If it is too close, it will be simpler, and it will cost a lot of nozzles. The service life of the nozzles will be doubled and even burned up.
