Modern CNC lathe the advantage of high speed cutting technology
Modern CNC lathe the advantages of high-speed cutting technology reflects release date: 2019 - 01 - 31 clicks: 2238 contemporary reflect now nc lathe the advantages of high-speed cutting technology, high speed cutting technology for the processing mould has very wide, it brought many advantages to the numerical control processing industry: 1. Greatly improve the efficiency of processing, machine tool not only high rotational speed, feed, and rough finish machining can be a complete, greatly improved the production efficiency, coupled with numerical control technology, mould manufacturing cycle can be shortened by about 40%. 2. High speed cutting mould don't need to do both electrodes, also do not need to subsequent grinding and polishing, also easy to implement process automation, improve the development velocity of the mould. 3. The high speed cutting technology can machining hardened steel, and can get very high surface quality, obtained by milling and grinding processing effect, not only save a lot of time, also improve the quality of the machined surface. In order to achieve the mold cavity and the related parts of the high speed machining, CNC lathe also need to have the following characteristics: 1. Large load and high rigidity is due to the mould is to develop in the direction of large-scale, processing equipment must have a large enough mesa size and working schedule. Now, a few tons to dozens of tons of mould is very common, machine tool working mesa can bear large weight. Strength and hardness of the die material is very high, and often USES the elongation of small diameter end milling cutter machining mold cavity, so the process prone to flutter. In order to ensure machining accuracy and surface quality of the parts, used for mould manufacturing high speed machine tools must have high dynamic and static stiffness, in order to improve the positioning accuracy of machine tools, tracking accuracy and ability to resist vibration. 2. High speed and high power high speed machining is the development direction, high speed milling has shown great superiority in the mold processing. In order to adapt to the mold cavity surface processing, tool radius should be less than minimum radius of circular of cavity surface, in order to avoid in the process of machining tool and workpiece happen & other; Interference & throughout; 。 Due to the tool diameter is small, so the spindle speed is very high. Mold and die parts, other parts finishing is usually done in a clamping workpiece, so the spindle power, medium size mould milling machine and machining center spindle power for 10 - often 40 kw, some even higher. 3. Can multi-axis linkage and good ability of deep hole cavity composite cutting mold cavity in the complex space 6 surface and grooves, and many die with deep hole cavity. For 3 d surface to achieve the high precision, high speed and high stability of the processing, machine tool requires multi-axis linkage, cutting and deep hole cavity with good comprehensive ability. Five-axis linkage machining center can be used, in addition to the linear motion of the three coordinates, and two feed movement of rotating coordinates. Milling head or workbench can be continuous rotary feed multi-axis linkage, which is suitable for processing with complex cavity surface mould parts.
