Assembly lines can almost completely complete a manufacturing object. Indeed, some manufactured goods are packaged without ever being touched by human hands. However, many products require the finishing touches that only hand grinders and polishers can deliver. 

These craftsmen grind and polish metal, stone, clay, plastic, and glass objects or parts with hand tools and hand-held power equipment. They may also be responsible for the repair and maintenance of equipment, the sharpening of abrasive grinding instruments, and the application of solutions and chemicals. 

You may be referred to as a grinder, chipper, polisher, buffer, or sander depending on the substance you work with and the instruments you employ. Typically, this position requires only little on-the-job training. To perform it successfully, you must be skilled with your hands and understand the phases of the specific process for which you have been employed. You must be able to perform the same task repeatedly without losing focus. 

Working circumstances can be noisy, and you will almost certainly be required to wear protective equipment, such as safety glasses, to protect yourself from flying particles. Grinding and polishing work is enjoyable for people who enjoy making things since it brings the item closer to perfection.
