          CNC machining machine spindle bearing configuration

          source: time:2019-10-23 09:12:28

          Generally, the spindle components of medium and small CNC machining machines mostly use rolling bearings as the spindle support. At present, there are mainly three types of deployment methods:

          1. Front support with double row short cylindrical roller

          Sub bearing (bearing) and 60. CNC machining is commanded by the control system to make the tool meet the requirements of various movements, in the form of numbers and letters to indicate the shape and size of the workpiece and other technical requirements and processing requirements. It refers to the process of machining parts on CNC machines. In order to improve the automation of production, shorten the programming time and reduce the cost of CNC machining, a series of advanced CNC machining technologies have been developed and used in the aerospace industry. The angular contact double-row radial thrust ball bearing combination and the rear support adopt a radial thrust ball bearing. This configuration (deploy) method greatly improves the overall rigidity of the spindle, and can meet the requirements of strong cutting. It is widely used in the spindles of various CNC machine tools (attributes: automatic machine tools). The rear bearing of this configuration can also be used with a cylindrical roller bearing to further increase the radial stiffness of the rear bearing.

          2. Front support with high precision (accuracy) double alignment

          Heart thrust ball bearing (bearing). CNC machining is commanded by the control system to make the tool meet the requirements of various movements, in the form of numbers and letters to indicate the shape and size of the workpiece and other technical requirements and processing requirements. It refers to the process of machining parts on CNC machines. In order to improve the automation of production, shorten the programming time and reduce the cost of CNC machining, a series of advanced CNC machining technologies have been developed and used in the aerospace industry. ? CNC machine tool (attribute: automatic machine tool) spindle bearing configuration (deploy) mode? Centripetal thrust ball bearing has good high-speed performance, the maximum spindle speed can reach 4000r / min, but its load capacity is small, only suitable for high speed, light load And the spindle of a precision (precise) CNC machine. To increase the spindle stiffness of this type of deployment, the front support can be combined with four or more bearings and the rear support can be combined with two bearings.

          3. The front and rear bearings (bearing) adopt double row and single row tapered roller bearings. The bearings can withstand large radial and axial forces, so that the main shaft can withstand heavy loads, especially with strong dynamic loads, good rigidity, installation and Debugging performance is good. Cnc processing General CNC machining usually refers to computer digital control precision machining, CNC machining lathes, CNC machining milling machines, CNC machining boring and milling machines. The finished feed routes are basically in the order of their part contours. Therefore, the focus of the determination of the feed route is to determine the feed path for roughing and idle travel. However, this configuration limits the maximum speed and accuracy (accuracy) of the spindle and is only suitable for medium-precision, low-speed and heavy-duty CNC machine tools (attributes: automated machine tools).
