Grinding
Grinding is a common metalworking process where workers use special tools and machines to smooth, shape, or finish metal surfaces. Think of it like very advanced sanding, but for metal parts. Workers might use handheld grinders for smaller jobs or operate large grinding machines for bigger industrial projects. This process is essential in manufacturing because it helps create precise, smooth finishes on metal parts, tools, and products. It's a fundamental skill in metalworking, similar to welding or cutting, and is used across many industries from auto repair to aerospace manufacturing.
