The main part of the CNC precision internal bore grinders is the bed. The bed is the basic support of the grinding machine. It is equipped with a grinding wheel frame, a work table, a head frame, a tailstock and a lateral sliding saddle. Keep these parts in exact relative position while working. The inside of the bed is used as an oil pool for hydraulic oil. The head frame is used to mount and hold the workpiece and rotate the workpiece. The head frame can be rotated 90° counterclockwise in the horizontal plane. The inner grinding tool is used to support the grinding wheel spindle of the grinding inner hole.
The grinding spindle of theCNC precision internal bore grinders is driven by a separate motor. The wheel carrier is used to support and drive the grinding wheel spindle at high speed. The wheel frame is mounted on the sliding saddle. When the short conical surface needs to be ground, the wheel frame can be adjusted to a certain angular position within the horizontal plane by ±30°, and the tailstock and the head frame together support the workpiece. The sliding saddle and the infeed mechanism rotate the lateral feed handwheel. The infeed mechanism can be driven to drive the saddle and the wheel frame thereon for lateral feed motion. The workbench consists of two layers.
The feed and compensation of CNC precision internal bore grinders are carried out by two non-interference transmission mechanisms. The feed system has a fixed grinding function, which adopts manual or hydraulic two-feed mode. The CNC precision internal bore grinders is equipped with Quick-jumping mechanism, so it is not necessary to re-tool manually after exiting the grinding wheel for measurement or trimming.
