Generally speaking, swindling vacuum sucker to grab the finished product is the cheapest way. There are various types of vacuum suction cups. The rubber suction cups can be operated under high temperature. The silicon rubber suction cups are quite suitable for catching the rough finished products. The polyurethane suction cups are very durable. In addition, in essence, if the sucker is required to have oil resistance, it is advisable to study the use of polyurethane, nitrile rubber or vinyl containing polymers and other raw materials to manufacture the sucker. Generally, in order to prevent the surface of the finished product from being scratched, it is better to choose the suction cup with wave tube made of NBR or silicone rubber as the raw material, which is made of NBR and has great breaking force, so it is commonly used in various vacuum holding equipment.
2、 The vacuum sucker used on the CNC computer gong is the foot color of the fixture beside the CNC machining center. Some workpieces require high surface smoothness, so the fixture of the commonly used CNC computer gong cannot be used. At this time, the vacuum sucker can be used. But we seldom use the vacuum sucker made of rubber near the CNC computer gongs, but more use the CNC vacuum sucker. The so-called CNC vacuum sucker is a kind of unique vacuum sucker that uses a vacuum generator plus a switch. The principle of drawing is the same as that of rubber vacuum sucker. They all create a vacuum environment to make the atmospheric pressure press the sucker on the workpiece, but the CNC vacuum sucker The vacuum of is produced by the vacuum generator in the vacuum environment, and there is a big difference in the appearance. The rubber vacuum sucker is a simple vacuum element, while the CNC vacuum sucker is the same as a big plate. The use of vacuum sucker in CNC computer gongs is usually due to the fact that the workpieces processed have high requirements for surface smoothness. Maybe it is only used when the fixture of CNC computer gongs cannot clamp the workpieces very well. It is a unique and cheap fixture in CNC machine tools.
