internal grinding machine 3l229v(a)
Internal grinding machines 3L229V(A) serve for grinding conical, cylindrical, through, and blind holes in items that require particularly high-precision surface processing. These models are equipped with a surfacing wheelhead, which provides the ability to simultaneously process the surface of the end face and hole.

Main features of internal grinding machines, model 3L229V(A), are as follows:

1.Availability of a wide range of rotational frequencies for grinding wheels, item spindle, cross feed, as well as for the speeds of the table movement. As a result, there is a favorable opportunity to process parts in the most optimal modes. The automated feed of the grinding wheelhead to the double table move increases productivity and also improves the quality of processing.

2. Rolling-type guides, used for the movement of the grinding wheelhead in the cross direction, paired with the end link (here a ball screw is used) give the required minimum of high-precision movements.

3. The grinding wheelhead carries out the adjustment movement as quickly as possible.

4. A control panel is provided for starting and stopping the operation of all equipment, as well as for turning on the hydraulic drive and switching the grinding spindles to rotation mode.

5. The design features of the internal grinding machines 3L229V(A) also consist in the existing automated stop of the item headstock spindle rotation, and in the suspension of the supply of a coolant during the withdrawal of the table from the area of grinding work and removal to the respective extreme position.
