This project was created to showcase the capabilities and effiency of our Y-axis lathes.

Besides being a very recognizable object, a chess rook contains features that require fairly basic machining operations that can be accomplished on 2-axis lathes and 4-axis mills. By completing the majority of operations in a single setup, it is easy to see how Y-axis lathes can significantly reduce processing time for each part.

The project was enhanced by adding 3D contour engraving of our logo and URL.

This part was an adaptation of smaller part we made in batches of 2,000. The original part specified S7 tool steel. For better video footage, we switched to 12L14 leaded steel for its excellent machinability, and we were able to complete the entire process without the use of coolant.

This project took full advantage of our Mori Seiki lathe's production capabilities. Continuous, unmanned production could be realized with the use of the subspindle, part ejector, and part catcher.

The large size of this aerospace part pushed the NL2500SY lathe to the limits of its work envelope. At 7 inches in diameter and 10 inches in length, this part left just a few inches of clearance for turret rotation. Furthermore, its features required the use of boring bars and axial live tools on both ends, using much of the Z-axis clearance.

ID chucking was accomplished using long soft-jaws turned to the proper diameter of 5.75 inches.
