How to choose CNC milling machine tool

In face milling, the tool used has different shapes and types according to its application scope. For the cutting edge of the tool, due to the friction of the cutting process, rapid heating, and sharp cooling down when idling, the requirements are very strict, and the cutting tool is required to have impact resistance, wear resistance and heat resistance. In order to soften the impact on the tip of the tool and easily discharge the iron filings, the shape of the sword must be fully studied. There are two kinds of front Angle to choose the end milling blade: one is the shoulder cutting type of the machining surface that is close to 90° with the workpiece, and the other is the flat cutting type that is favorable for tool wear.

Selection of cutting speed according to the amount of back cutting, feed and tool durability selection of cutting speed, improving cutting speed is also a measure to improve productivity. It can also be selected according to the production time experience in the cutting speed range allowed by the machine manual or refer to the relevant cutting parameters manual. After the cutting speed is determined, the spindle speed of the machine can be calculated according to n=1000Vc/πd. The selection of feed amount is an important parameter of machine tool cutting parameters, according to the surface roughness of parts, processing accuracy requirements, tools and workpiece materials and other factors, the feed amount can generally be Vf=fn=fzZn.
