What Are The Differences Between Cnc Machining Center In Processing Plastic And Metal Materials, What Should Be Paid Attention To, And What Are The Differences In Programming

[Esperanza Goudy]

end mills should be used to process plastics. The cutting edge should be sharp and water-cooled. The spindle speed should be faster (the speed of the machining center is 3000-5000). The cutting amount (1-5mm per cutter for rough machining and ball end mills for finish machining) should be 2500mm-3500mm per minute. In addition, the plastic clamping should be firm (to prevent the loosening of the clamp and the deformation of plastic products); Flying knives and tungsten steel knives can be used for metal processing. It is best to select the cutting tool with R angle for finish machining, which can improve the finish. When programming, the size of the cutting tool and the old and new state of the cutting tool are mainly considered, (for example, when milling metal 10mm matching holes, the holes programmed with 4mm are only 9.95-9.99, and there is no 10mm, so the programming needs to do 3.96-3.99 knife operation. The 4mm knife is used for plastic and metal processing. The main consideration is to let the knife. side milling operation The operation should pay attention to swinging the knife,

it is made by hand, and I hope it can be adopted

when processing plastic, high-speed cutting will make the plastic soft and sticky. When processing plastic, it is necessary to turn the knife at high speed, air-cooled or water-cooled. Use a sharp knife, preferably a carbide knife. The rotating speed of metal processing and tool feeding should be appropriate. Too high rotating speed will increase the wear of the tool. The tool feeding is large and the cleanliness is poor. Fortunately, the tool is damaged.

when machining metal and plastic, the spindle speed and feed rate are different, and the cutting tool is also different. Pay attention to the position of cutting tool during programming
