Three Forms of CNC Lathe Spindle

The precision, stiffness and thermal denaturation of CNC lathe spindle parts directly affect the machining quality. These effects are exacerbated by the fact that CNC lathes do not require manual adjustments during machining. At present, there are three main types of CNC lathe spindles.


1. Double row short cylindrical roller bearing and 60° angular contact double row radial thrust ball bearing


The front support of the CNC lathe 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 pairs of radial thrust ball bearings. The 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.


2. High precision double row angular contact ball bearings and single row (or double row) angular contact ball bearings


The front bearing of CNC lathe adopts high-precision double row angular contact ball bearing, and the rear bearing adopts single row (or double row) angular contact ball bearing. This configuration has good high-speed performance, but its load-carrying capacity is small, so it is suitable for high-speed, light-load and precision CNC lathe spindles.


3. Double and single row tapered bearings


Double row and single row tapered bearings are used for front and rear bearings. This structure limits the high-speed and precision of the spindle, and is suitable for the spindle of medium-precision, low-speed, and heavy-duty CNC lathes.


The simple CNC lathe formed by transforming the feeding system of the ordinary lathe by stepping motor and single-chip microcomputer has low cost, but the degree of automation and function is poor, and the turning accuracy is not high. For low-demand rotating parts.


According to the turning requirements, the CNC lathe is specially designed and equipped with a general CNC system. The CNC system has powerful functions, high automation and high machining accuracy. It is suitable for turning of general rotary parts. A CNC lathe can control two axes simultaneously, the X axis and the Z axis.
