Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If designed specifically for cermet materials
Grinding machines principally for cermets have distinct subheadings from metal-focused machines.
If for horizontal spindle surface grinding
Different machine configuration and grinding action changes primary classification.
If for semiconductor wafer metrology equipment
Wafer preparation grinders/polishers per statistical notes may classify under semiconductor-specific provisions.
