Now the development trend of the industry is quite good. This is a scene that we can all see. Because there are too many products driving, handboard is one of them. So what are the precautions for high-speed processing of handboard?

1.由于CNC手板正在向大型化方向發(fā)展，幾噸到幾十噸的手板非常普遍，因此要求機(jī)床工作臺面能承受大重量，這就要求設(shè)備必須具有大承重和高剛性的特性，還必須有足夠大的臺面尺寸和工作行程與之相適應(yīng)。另手板材料的強(qiáng)度和硬度都很高，加上常常采用伸長量較大的小直徑端銑刀加工手板型腔，因此加工過程容易發(fā)生顫振。為了確保零件的加工精度和表面質(zhì)量，手板制造的高速機(jī)床必須有很高的動、靜剛度，以提高機(jī)床的定位精度、跟蹤精度和抗振能力。

1. As CNC handboards are developing towards large-scale, handboards of several tons to dozens of tons are very common. Therefore, it is required that the machine tool worktable can bear large weight, which requires that the equipment must have the characteristics of large load-bearing and high rigidity, and there must be a large enough table size and work schedule to adapt to it. On the other hand, the strength and hardness of the hand plate material are very high, and the small diameter end milling cutter with large elongation is often used to process the hand plate cavity, so the machining process is prone to chatter. In order to ensure the machining accuracy and surface quality of the parts, the high-speed machine tool made by hand plate must have high dynamic and static stiffness, so as to improve the positioning accuracy, tracking accuracy and anti vibration ability of the machine tool.
           

2.高轉(zhuǎn)速和大功率高速加工是發(fā)展方向，手板廠的高速銑削在手板加工中已顯示了大的優(yōu)越性。為了適應(yīng)手板型腔曲面的加工，刀具的半徑應(yīng)小于型腔曲面小圓周半徑，以免加工過程中刀具與工件發(fā)生干涉。由于刀具直徑小，因此要求主軸轉(zhuǎn)速非常高，國外高速加工機(jī)床主軸轉(zhuǎn)速已達(dá)到4萬~10萬r/min，快速進(jìn)給速度可達(dá)3萬~6萬min。型腔和手板零件其他部件粗、精加工常常在工件一次裝夾中完成，故主軸功率要大，中等尺寸手板銑床和加工的主軸功率常為10~40kw。

2. High speed and high-power high-speed machining is the development direction. The high-speed milling of handboard factory has shown great advantages in handboard machining. In order to adapt to the processing of the hand plate cavity surface, the radius of the cutter should be less than the small circle radius of the cavity surface, so as to avoid the interference between the cutter and the workpiece in the processing. Due to the small tool diameter, the spindle speed is required to be very high. The spindle speed of foreign high-speed machining machine tools has reached 40000 ~ 100000 R / min, and the rapid feed speed can reach 30000 ~ 60000 min. The rough and finish machining of the cavity and other parts of the hand plate parts is often completed in one-time clamping of the workpiece, so the spindle power is large. The spindle power of medium-sized hand plate milling machine and machining center is usually 10 ~ 40kW.

3.能多軸聯(lián)動及良好的深孔腔綜合切削能力手板型腔多為復(fù)雜的空間六曲面及溝槽所構(gòu)成，且許多手板具有深孔腔。為了達(dá)到對3d曲面的高精度、高速度和高穩(wěn)定性加工，機(jī)床需要多軸聯(lián)動，且具有良好的深孔腔綜合切削能力。可以采用五軸聯(lián)動加工，除了三個坐標(biāo)的直線運(yùn)動外，還有兩個旋轉(zhuǎn)坐標(biāo)的進(jìn)給運(yùn)動。銑頭或工作臺可以多軸聯(lián)動進(jìn)行連續(xù)回轉(zhuǎn)進(jìn)給，從而適用于加工具有復(fù)雜型腔曲面的手板零件。

3. Multi axis linkage and good comprehensive cutting ability of deep hole cavity. Most of the hand plate cavities are composed of complex spatial six curved surfaces and grooves, and many hand plates have deep hole cavities. In order to achieve high precision, high speed and high stability of 3D surface machining, the machine tool needs multi axis linkage, and has good deep hole cavity comprehensive cutting ability. Five axis machining center can be used, in addition to the linear motion of three coordinates, there are two rotating coordinates of the feed motion. The milling head or worktable can rotate continuously by multi axis linkage, so it is suitable for machining hand parts with complex cavity surface.
