Frequently Asked Questions
Q1: What is the difference between the black and white models of the Automatic Grinder Machine?
A: The black model of the Automatic Grinder Machine requires an external air compressor to operate, while the white model has a built-in compressor. Both models support 110V and 220V power supply. If you already have an air compressor in your workshop, the black model is a cost-effective choice. If you need a standalone unit, the white model is recommended.
