When the cutting machine/cutting machine cuts, in order to effectively cut the material to prevent damage to the die, a non-metallic pad is placed in the direction of the knife edge. The purpose is to better cut the material, effectively protect the die and extend the die surface, while preventing the vibration caused by the impact of the machine metal directly on the metal from affecting the machine.
However, in recent years, many industries have higher and higher requirements for product quality. For example, the plastic products required for the electronics industry, the pharmaceutical industry, and foreign trade export have higher requirements for their product quality. The edges of the product are smooth and have no burrs. This also occurs when the cutting machine cuts the material directly using the die to cut the steel plate. The knife die directly cuts the steel plate to make the finished product work well, and the edge is smooth and free of burrs, which greatly improves the product quality.
However, in pursuit of product quality, it also puts more stringent conditions on the cutting machine. At present, most machines in the market do not meet the appeal requirements according to strict conditions. Why?
Let's take a look: the better precision of the cutting machine manufacturers will be controlled within 0.1mm, the small manufacturers will exceed 0.2mm plus the reaction time of the hydraulic system reaction time and depth adjustment time relay, the actual accuracy Will be greater than the appeal value. If the requirements can be met, the repeating cutting precision of the machine should not exceed 0.05mm.
Then why are there still many manufacturers still using it, and can it be cut normally? In fact, if you look at it carefully, you will find that most manufacturers have padded a thick plank on the back of the die or the back of the cut steel plate. The wood is compressive, and most of the error of the machine is offset by the elasticity of the wood, even though There are still many, the die is broken, and often waits for the situation to occur, which greatly affects production efficiency.
Here to remind the majority of users:
1, the thickness of the back of the thick die or the thickness of the back of the cut steel plate
2, steel plate volume should not choose normal stainless steel material with too hard hardness
3, try not to choose time control, select position control will get better cutting effect
The above is the precautions for selecting the machine, for your reference.
If the conditional control or pressure control can be selected, the better cutting effect can be obtained. The position control can directly touch the position switch mode, and the adjustment is simple and convenient, safe and reliable. Pressure control can be used by PLC, man-machine interface, and proportional valve. It can be used to store the die into memory. The tool can be switched directly, and the pressure is stable. It does not hurt the die, and the cutting effect is good. Set the advantages to increase production efficiency and reduce the cost of use
