Many users have asked about the requirements of CNC lathes for spindle components. The following editor will introduce to you:

1. Stiffness

When the equipment is working, high-speed cutting is generally used, which requires high rigidity of the spindle components. Otherwise, the spindle will produce large elastic deformation under the action of external force and cause vibration, which will affect the precision and surface roughness of the processed parts. .

2. Rotation accuracy

The co-rotation accuracy of the spindle components of CNC machine tools mainly refers to the radial runout and axial runout measured with a dial indicator when the workpiece, fixture or tool surface is installed at low speed and no load at the front end of the spindle. . Its height directly affects the geometric accuracy and surface quality of the machined parts.

3. Shock resistance

The shock resistance of the spindle components of CNC machine tools refers to the ability of the spindle components to resist vibration and maintain balanced operation during CNC machining.

4. Strong thermal stability

The thermal stability of spindle components mainly refers to the ability of the component to resist shape and position changes caused by heat. When the CNC machine tool is working, heat will be generated due to friction, oil stirring, etc., which will cause the temperature of the main shaft parts to be unbalanced, deform the shape and position of the main shaft parts, and affect the machining accuracy.

5. Reliable and accurate positioning.

The structure of the spindle components of CNC machine tools should ensure reliable radial positioning accuracy and axial positioning accuracy, so as to ensure reliable clamping and accurate positioning of workpieces or tools, and reduce the impact of clamping errors and positioning errors on processing quality.
