Discussion on abnormal sound of wire cutting machine tool brand
Today, we will discuss the problem of abnormal sound in the process of wire cutting:
In the process of wire cutting, there are generally five cases of abnormal sound:
1. Abnormal sound is generated at the moment of commutation: usually, the coupling or the key becomes loose. At this time, it is necessary to check which key becomes loose and replace it after checking. For the coupling to check whether there is wear part of the connection, if there is wear phenomenon, also want to replace in time, to ensure that the buffer function is really effective.
2, there is a foreign body sound in the wire drum, generally because there are small metal fragments or molybdenum wire head into the wire drum, if the dynamic balance adjustment screw in the wire drum does not fall off, as long as the continuous operation, then the small metal fragments or molybdenum wire head will automatically disappear, so there is no need to maintain.
3, the machine tool belt or gear abnormal sound, then need to check whether the belt or gear has been worn, linear cutting machine tool brand if it has been worn, must be replaced with the belt and gear.
4, if the wire cutting screw produced abnormal sound, this is a big problem, because the screw is attention to the components, replacement cost is very high, so you have to carefully check the reason, generally is caused by the screw within the debris. Just clear the clutter.
5, there is a machine tool is the motor fan will produce abnormal sound, at this time as long as the replacement of the fan can be.
When we are in the wire-cutting machine tool processing process, a customer asked, using water-based working fluid for wire-cutting processing, the surface of the workpiece has the color of rust, wipe will be black, what is the reason?
First, the phenomenon with the machine working liquid correlation is not big, because traditional oily emulsified oil also has this kind of phenomenon, with the water-base working fluid of different processing of workpiece surface residue after color is different, one is a dark, dark, sticky, use water-based working liquid surface of workpiece is yellow, like rust color residues, at this time as long as a wipe gently with the treasure tamar cleaner can clean, these two kinds of different colors of residue is mainly due to the emulsified oil and aqueous fluid contains different raw material.
Second, wedm brand when wiped clean with cleaner, the workpiece surface and the phenomenon of black, it's related to operating personnel, note if wedm processing the selection of high-frequency parameters associated with machine tool feed speed mismatch, machine tool feed speed when the fast slowly, when the surface for a long time, the temperature is too high, the artifact will be scorched, at this moment the operator must adjust the optimum parameters of the high frequency parameters and machine tool feed rate is consistent, at the same time pay attention to adjust the size of the water, so that the discharge to melt down and dirty thing to rinse the fastest speed and workpiece surface cooling not surface burns as soon as possible, This phenomenon can disappear
