Drilling milling machine requirements for spindle

 Zaozhuang Make Machinery Co., Ltd. has certain requirements for the planning of the spindle assembly of the drilling and milling machine. Generally speaking, the following planning should be achieved to meet the needs. Zaozhuang Make Machinery Co., Ltd. introduces the specific planning requirements for the spindle assembly as follows:

  1) Rotation accuracy. It means that the drilling and milling machine is in no-load and low-grade rotary (motorized or manual), and the radial and axial runout values of the workpiece or tool part at the front end of the spindle meet the requirements (for the value, please refer to the relevant machine tool accuracy standards). The intention is to ensure the precision and surface roughness of the machined parts.

  2) Stiffness. Refers to the ability of the spindle assembly to maintain a certain operating accuracy under the effect of external forces (such as cutting forces). When the rigidity is lacking, it not only affects the machining accuracy and appearance quality, but also easily causes oscillation. Deteriorating operating conditions of transmission parts and bearings. When planning, the stiffness value should be increased as much as possible under other conditions allowed.

  3) Vibration resistance. Refers to the ability of the spindle assembly to resist forced oscillation and self-excited oscillation during the cutting process to maintain stable work. Vibration resistance directly affects the surface quality and productivity of processing, and should be improved as much as possible.

  4) Temperature rise and thermal deformation. We know that temperature rise will cause thermal deformation of the drilling and milling machine components, change the relative orientation of the spindle rotation center, affect the machining accuracy, and too high temperature will change the gap of the original components such as bearings, damage the smooth conditions, accelerate wear and even hold the shaft.

  5) Abrasion resistance. The precision persistence of the drilling and milling machine spindle assembly refers to the ability to maintain its initial production accuracy for a long time. For this reason, the sliding appearance of the spindle assembly includes the mating surface of the spindle journal and the sliding bearing, and the axial movement of the spindle of the drilling and milling machine The guide surface of the component, the front end of the spindle and the inner taper hole, etc. must have a certain degree of hardness and wear resistance.
