What are the reasons for the chipping of CNC shearing machine tools?

CNC shearing machine in many processing applications, in the use of the process, due to many friends of the operation is not reasonable, resulting in the frequent occurrence of tool chipping phenomenon. General often easy to cause chipping may be the following aspects of the main reasons.

First of all, the plate may be cut too hard, this we need to pay attention to in the process of operation, can not be any material with a knife to cut, otherwise it is easy to cause chipping. If you encounter a very hard material, we must change a more suitable knife plate, maintenance is very important, otherwise the good knife plate to your hands can not be used for a long time.

Secondly, in shear plate, the gap for the knife mouth we also need to carefully debug, otherwise it is also easy to cause chipping.
Again in shear round steel is the most likely to cause chipping, if this material we need to be extra careful.

Finally, it may also be the quality of the blade itself, we must not be greedy for cheap and choose a bad quality blade, after all, this is a very important place for shearing machine.

Hydraulic shearing machine, we must know and pay attention to, specifically, the words are the following.

(1) hydraulic shearing machine, if the use of rectangular lower blade, then, can be four edge shear, so that you can extend the life of the blade in the shearing machine.

(2) in its workbench, is generally equipped with auxiliary knife seat, to facilitate the blade, fine tuning adjustment, so that there is a good adjustment effect.

(3) hydraulic shearing machine, its adjustment in the blade gap, is possible to use the mechanism of infinitely adjustable, in order to adapt to different plate thickness, and different material shear requirements. In addition, the shear stroke, it is also possible to make appropriate adjustments. In addition, the number of shears can also be automatically counted, so that the workload can be reduced.

(4) hydraulic shearing machine hydraulic oil good viscosity-temperature. Viscosity temperature refers to the oil viscosity rise and fall with the temperature and the degree of change, usually expressed in terms of viscosity index. The greater the viscosity index, shearing machine hydraulic system viscosity of the oil with the temperature drop is smaller, so that the internal leakage of the hydraulic system is not too large.

(5) shearing machine hydraulic system operating conditions are generally more severe, the operating process of hydraulic oil temperature with the load and ambient temperature and change, viscosity index generally shall not be less than 90.
