Necessary conditions for normal processing of CNC opener
When we want to use the CNC opener to work, we need to check whether the opener has the necessary conditions for normal processing.If you want to know more, please read on:
(1) A certain amount of gap must be maintained between the tool electrode and the processed surface of the workpiece. The size of the gap is determined by electrical specifications such as processing voltage, pulse current, and pulse gap. The gap size is generally between tens of microns.If the gap is smaller or larger than this distance, no spark discharge can be performed.The gap is too small, the positive and negative electrodes are easy to short circuit, and spark discharge cannot be generated.
(2) CNC cutting machine must be carried out in the insulating working fluid when cutting the workpiece.Commonly used insulating working fluids include kerosene, saponification fluid, deionized water, etc. The working fluids used are different. Under the same electrical standards, the processing speed and surface accuracy are also different.The use of insulating working fluid mainly has the following functions: It is conducive to the generation of pulsed spark discharge; it eliminates the products of electric corrosion in the gap; and it acts as a cooling electrode. (3) With pulse power, spark discharge must be pulsed and intermittent.
(4) The material to be processed must be conductive.Only conductive materials can produce spark discharges, and conductive materials are generally metallic materials and semiconductor non-metallic materials. Three points of daily maintenance of CNC opener First, do a good job of dust removal on the table of CNC opener and various parts.Once the dust enters the equipment, it will cause great trouble to the equipment, affect the normal use of the equipment, and affect the production efficiency.Therefore, in daily use, it is necessary to do a good job of cleaning the machine table and the surface of the cabinet.
Secondly, it is necessary to do rust prevention work on the CNC opener .Once the equipment is rusted, problems such as aging of some components will reduce the working efficiency of the CNC opener. Therefore, the equipment must be regularly coated with rust preventive oil to prevent the equipment from rusting.
Third, do a good job of lubricating the transmission of the CNC opener .When the equipment is running, if the equipment transmission device does not run smoothly, it will cause uneven feeding of the equipment, affect the quality of the blanking, and have a certain impact on industrial production.Therefore, it is very important to lubricate the equipment transmission in daily maintenance.
