How to choose a used die cutting machine? Let Gerson tell you some tips:
First, whether the fuselage formation; Second hand cutting machine maintenance introduction, cutting machine is the most important but the fuselage, fuselage if the said of the whole cutting machine will not be used, the general naked eye can not see whether the fuselage has been After several years of use of the machine we do not need to use micrometer to measure, just use steel tape can be roughly measured, the method is to measure the distance between the four corners of the upper and lower table when the machine is Stationary, the use of the requirements are not high not more than 0.5 mm will not affect the use. If you go beyond that, you have to be careful.
The second, column or copper sleeve is worn, generally, there is only a gap of 0.08 mm between the column and the copper sleeve, and the machine will not feel shaking when cutting. If it feels shaking when cutting or moving up and down, The gap between the column and the copper sleeve will prove to be very large, which is difficult to repair.
Third, whether the circuit is aging; second aging is easy to check, second-hand cutting machine maintenance introduction, as long as the wire back and forth fold a few times, if the wire is soft no hair hard that there is no aging, And then carefully observe whether the electrical components burned black can roughly judge the quality of electrical components.
Fourth, whether the pressure of the hydraulic system meets the standard; The inspection of hydraulic system needs more professional skills to be seen, because it is too complicated and not easy to operate, so I won’t say too much here. Only to give The general method, start the machine to listen for noise, hydraulic components and pipe joints there is no obvious oil leakage, there is no trace of hydraulic oil on the ground below the machine.
Second hand cutting machine maintenance introduction, accessories including cutting machine around the cover, safety eye, plate, rubber pad, cutting machine internal lubrication pipeline and so on. These accessories should not be too valuable but not without, some Of the accessories can not be used so try not to lack. When buying the second-hand cutting machine, we need to electrize the test machine after completing the inspection of the above matters. We will decide to buy it after putting the knife mold and Materials on the machine for specific and real operation.
