THK BNK1010-1.5RRG2+290LC7Y Ball Screw Finished Shaft Ends

THK BNK1010-1.5RRG2+290LC7Y ball screw has a wide range of applications

Mechanical processing field

CNC machine tools: In CNC machine tools, THK BNK1010-1.5RRG2+290LC7Y ball screw can achieve high-precision linear motion control to ensure the dimensional accuracy and surface quality of the processed parts. For example, in milling, turning and other processing processes, the ball screw can accurately control the feed movement of the tool to improve processing efficiency and accuracy.

Grinding machine: The application of THK BNK1010-1.5RRG2+290LC7Y ball screw in grinding machines is also very important. In the ball screw grinding wheel forming grinding wheel dressing process, the dressing parameters have a significant effect on the grinding wheel topography and the sharpness of the grinding wheel, thereby affecting the grinding wheel wear, grinding force, grinding temperature and the surface integrity of the grinding parts. By accurately controlling the movement of the ball screw, the grinding wheel can be accurately dressed and the grinding quality can be improved.
