Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If surface grinding configuration
If primarily flat surface rather than cylindrical finishing, classifies under surface grinding machines.
If dividing heads or indexing accessories dominate
Machines where indexing accessories represent main function classify as accessories.
If precision measuring integrated
If grinding function secondary to metrology/measuring, falls under Chapter 90.
