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发展，几吨到几十吨的手板非常普遍，因此要求机床工作台面能承受大重量，这就要求设备必须具有大承重和高刚性的特性，还必须有足够大的台面尺寸和工作行程与之相适应。另手板材料的强度和硬度都很高，加上常常采用伸长量较大的小直径端铣刀加工手板型腔，因此加工过程容易发生颤振。为了确保零件的加工精度和表面质量，手板制造的高速机床必须有很高的动、静刚度，以提高机床的定位精度、跟踪精度和抗振能力。

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.高转速和大功率高速加工是发展方向，手板厂的高速铣削在手板加工中已显示了大的优越性。为了适应手板型腔曲面的加工，刀具的半径应小于型腔曲面小圆周半径，以免加工过程中刀具与工件发生干涉。由于刀具直径小，因此要求主轴转速非常高，国外高速加工机床主轴转速已达到4万~10万r/min，快速进给速度可达3万~6万min。型腔和手板零件其他部件粗、精加工常常在工件一次装夹中完成，故主轴功率要大，中等尺寸手板铣床和加工的主轴功率常为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.能多轴联动及良好的深孔腔综合切削能力手板型腔多为复杂的空间六曲面及沟槽所构成，且许多手板具有深孔腔。为了达到对3d曲面的高精度、高速度和高稳定性加工，机床需要多轴联动，且具有良好的深孔腔综合切削能力。可以采用五轴联动加工，除了三个坐标的直线运动外，还有两个旋转坐标的进给运动。铣头或工作台可以多轴联动进行连续回转进给，从而适用于加工具有复杂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.
