Three forms of cnc wheel lathe machine spindle

The accuracy, stiffness and thermal deformation of the spindle parts of the cnc wheel lathe machine directly affect the machining quality. As cnc wheel lathe machine do not require manual adjustment during processing, these effects are even more serious. At present, there are mainly three types of spindles for cnc wheel lathes.
The front support is composed of double row short cylindrical roller bearings and 60° angular contact double row radial thrust ball bearings, and the rear support is equipped with a pair of radial thrust ball bearings. This structure greatly improves the overall rigidity of the spindle, can meet the requirements of strong chips, and is widely used in various CNC lathes of small CNC lathe manufacturers.
The front bearing adopts high-precision double row angular contact ball bearings, and the rear bearing adopts single row (or double row) angular contact ball bearings. This configuration has good high speed performance, but its load capacity is small, so it is suitable for high speed, light load and precision CNC lathe spindles.
Double row and single row tapered bearings are used for front and rear bearings. This structure limits the high speed and accuracy of the spindle, and is suitable for the spindle of medium-precision, low-speed, and heavy-duty CNC lathes.
The simple numerical control lathe formed by using stepper motor and single chip microcomputer to transform the feed system of ordinary lathe has low cost, but the degree of automation and functions are poor, and the turning accuracy is not high. Suitable for rotating parts with low requirements.
According to the turning requirements, the cnc wheel lathe machine is specially designed and equipped with a general numerical control system. The numerical control system has powerful functions, high degree of automation and high processing precision. It is suitable for turning processing of general rotating parts. The CNC lathe can control two axes at the same time, namely X axis and Z axis.
