How large is the cutting accuracy of hydraulic cutting machine?
As is known to all, the cutting accuracy of hydraulic cutting machine is much higher than that of mechanical cutting machine, especially the precision hydraulic cutting machine.
According to the standard, the cutting precision of hydraulic cutting machine can not be greater than 0.1mm, but it is often higher than this value in actual use. I have seen that the machine precision of 3 years is more than 2mm, and this kind of situation is still a lot.
1, what is the impact of poor precision
I think the effect of the machine precision difference can be realized by all users. The efficiency is low: the main performance is often a constant phenomenon or the middle can be cut off in the middle. It needs to be cut off with a knife or scissors. This also greatly reduces the efficiency of work; cutting the cushion plate is too fast: after cutting the plate in the middle or a position in advance, the cushion plate is reported ahead of time. Waste, which virtually increases production costs, is often bad for knife dies: often, there are knife dies being destroyed without any reason.
2, what factors depend on the accuracy of the machine
The accuracy of machine depends on 3 aspects: the accuracy of machining, the stability of hydraulic system, and the stability of electrical control. The parts and electrical components of the hydraulic system are generally purchased, and the quality is in turn: the whole import, the joint venture brand, and the domestic (of course this is not absolute), so the purchase of the foreign parts is not the basic problem of the big factory or the brand. The rest is mainly mechanical parts. Due to the uneven residuals of domestic manufacturers, the machining accuracy and technology are quite different.
3, how to control or reduce the error of machine precision
The control precision error is divided into two parts of the manufacturer and the user: the manufacturers above are mainly concerned with improving the machining precision of the machinery and doing a good job of the whole process process. As the user, it is mainly to do the daily maintenance and maintenance of the machine.
