CNC flame cutting machine cutting mouth supplies application knowledge entry

Release time: 2017-06-12 11:09:45

Large-scale CNC machine tools such as CNC flame cutting machine daily maintenance work, the more important point is that the use of cutting mouth supplies maintenance problems, good operators for CNC flame cutting machine cutting mouth supplies have some unique insights and skills , Not only to help enterprises in the bulk cutting process to reduce the use of equipment costs, but also to protect the machine tool cutting quality and effectiveness.
So for the NC flame cutting machine cutting mouth use, there are those who deserve the attention of enterprises and operators of the place? We believe that in the use of the process, taking into account the NC flame cutting machine used in the plate processing shop, the maintenance of workers is not enough, the machine life will have an impact, especially as a consumable flame cutting machine cutting mouth, Its maintenance and use is difficult to place, resulting in cutting mouth loss is too large. From the cutting principle, the cutting of the mouth of the flame to obtain high-precision cutting of a very important part of the cutting, the operation of the correct or not will determine the extent of the final cutting effect. The following are the same as the "
CNC flame cutting machine cutting with a large thickness of carbon steel cutting capacity, because of its cutting workpiece thickness, cutting surface vertical, coupled with the advantages of low cutting costs, has been CNC cutting equipment than customers popular cutting method. In the daily processing and use, for cutting the mouth to use its related knowledge and precautions, including cutting the mouth of the selection, daily cleaning and maintenance, cutting height control and other aspects, for the convenience of everyone to understand, the following we will specify one by one:
1. Note that cutting mouth cleaning and maintenance
CNC flame cutting machine cutting mouth is also easy to damage the equipment parts of one of the supplies. Therefore, the CNC cutting cut mouth to do the appropriate cleaning and maintenance, not only can improve the efficiency of CNC cutting machine to ensure the quality of its cutting, but also to extend the life of CNC flame cutting machine. Thereby reducing production costs.
2. Timely to clear the mouth to prevent clogging
In the process of cutting the CNC flame cutting machine, the slag splashing in the high heat state is easy to plug the cut mouth, so the cutting and maintenance of the cutting mouth is very important. When cutting the cut mouth, turn off the preheat oxygen hand valve; press the cut oxygen button to open the cutting oxygen solenoid valve; turn off the cutting torch on the torch so that the nozzle can be inserted into the nozzle, In the fast oxygen hole twitching up and down, and slowly open the torch to cut the oxygen hand valve.
3. Cutting tip height control
Set the appropriate spacing between the cutting and cutting of the CNC flame cutting machine. CNC flame cutting machine without automatic increase, the operator should always pay attention to the distance between the cutting nozzle from the workpiece. When the top of the primary flame (flame core) is about 1 mm on the workpiece, it is the ideal spacing of the cut mouth. Also need to be adjusted according to the use of cutting gas appropriate cut mouth height, such as with acetylene from 3 to 10mm, with other gas from 6 to 12mm. On the other hand, if the steel plate deformation or uneven should also be adjusted. When using propane or natural gas as the gas, cutting the thickness to 50mm, the cut mouth height should be doubled.
4. cut mouth selection
Select the appropriate CNC flame cutting machine cutting mouth model. Chopper type selection need to be based on the use of gas and cutting materials and thickness to consider, this we have in the previous technical articles have also been listed in detail, no longer tired in this.
