25-05-2011· Rolled screws were typically used in non-precise applications, such as in pick-and-place devices, and as actuators. Ground ball screws were used as the drive mechanism in precision machine tools (milling machines, lathes, profile grinders, turning centers, EDM machines, and so on). Additionally, ground ball screws have been the product of ...
The diameter of a grinding spindle is heavily dependent on the pitch angle. The greater the pitch angle, the lower the rigidity of the spindle and the lower the possible metal rate removal. This leads to higher cycle times. The trend towards ball screw nuts with a large pitch which makes grinding even less suitable as a machining technique.
If the screw is brass, it would be easy to grind down. You have several options. With 1/4 inch remaining above the surface, I might first cut it down rather than grinding it all down. A piece of hacksaw blade will suffice, held in my hand flat against the surface to avoid damaging the wood.
