ZuoLong mechanical explanation: the analysis of the causes of cutting machine power decrease

Cutting machine in the process of long-term use, there are some more or less losses such as cutting speed slow, cutting accuracy issue such as difference of change, a lot of people think is power down. Impact cutting machine, there are a lot of power to the cause is not necessarily a problem. Cutting machine power decrease under the following analysis for everyone:

first is focus position, focus location affect the cutting precision, especially the focal spot diameter. Focal spot diameter as small as possible, to produce a narrow kerf width; Focal spot diameter and is directly proportional to the depth of focus of the focusing lens and focus lens focal depth is smaller, the smaller focal spot diameter.

the second is the distance between the nozzle, and nozzle distance also affect cutting machine processing power. Distance will cause unnecessary and kinetic energy waste products of getting too close to spill will affect the bulk cutting ability to disperse, the appropriate distance is 0. 8毫米。 Other cutting machine for surface uneven cutting processing is mainly accomplished by the servo control, running in the process of the nozzle and the height of the machined part should always be consistent.

again is cutting speed, cutting speed has a great influence on the power of cutting machine, cutting speed is proportional to the cutting machine of power. Cutting quality is associated with the beam quality at the same time, it also related to the characteristics of the beam focusing system, namely the size of beam focus after has a great influence on the cutting quality.

then the auxiliary gas, auxiliary gas and gas pressure also has effect on the power of cutting machine, the size of the auxiliary gas suggest using compressed air or inert gas. If processing material thickness increase or cutting speed should be appropriate to reduce the gas pressure, the slower to use low gas pressure cutting can prevent the trimming the frost.

the last is power, if the first 4 items have been ruled out, just consider is power down. Any device used for a long time will appear some parts after the aging phenomenon. Device is the core of the cutting machine important component, also can appear after long time use power decrease. In addition to the above, the performance of the materials, size and thickness will affect the power decrease cutting machine.
