CNC lathes can be used for machining complex rotary shapes. Milling is to fixing the blank, with a high-speed rotating milling cutter on the blank to cut out the desired shape and features. Traditional milling is mostly used for milling simple contour features such as Outlines and grooves. CNC milling machines can be used for machining complex shapes and features. The milling and boring machining center can carry out three-axis or multi-axis milling and boring machining, used for machining, molding, gage, fetal, thin-wall complex surface, artificial prosthesis, blade, and so on. When choosing the content of NC milling, the advantages and key role of NC milling machines should be given full play.
In addition to the characteristics of ordinary milling machines, CNC milling has the following characteristics:
(1) Strong adaptability and flexibility of parts processing, can process the contour shape is particularly complex or difficult to control the size of the parts, such as mold parts, shell parts, etc.
② Can process ordinary machine tools can not be processed or difficult to process parts, such as the mathematical model described by the complex curve parts and three-dimensional space curved parts.
③ It can process the parts that need to be processed by multiple processes after clamping and positioning.
High machining precision, stable and reliable machining quality.
⑤ High degree of production automation can reduce the labor intensity of the operator. It is conducive to the automation of production management.
⑥ High production efficiency.
⑦ From the cutting principle, whether the end milling or the cycle milling belongs to the intermittent cutting mode, rather than continuous cutting-like turning, so the requirements of the tool are higher, and the requirements have good impact resistance, toughness, and wear resistance. In the dry cutting condition, also requires a good red rigid.
