Cylindrical grinder operator

Cylindrical grinder operators set up and tend cylindrical grinding machines designed to apply abrasive processes in order to remove small amounts of excess material and smoothen metal workpieces by multiple abrasive grinding wheels with diamond teeth as a cutting device for very precise and light cuts, as the workpiece is fed past it and formed into a cylinder.

Cylindrical grinder operators are employed full time. Some work more than 40 hours per week. Because many manufacturers run their machinery for extended periods, evening and weekend work is also common.

These workers often operate powerful, high-speed machines that can be dangerous and must observe safety rules. Operators usually wear protective equipment, such as safety glasses, earplugs, and steel-toed boots, to guard against flying particles of metal or plastic, machine noise, and heavy objects, respectively.

Other required safety equipment varies by work setting and machine. For example, respirators are common for those who work near materials that emit dangerous fumes or dust.

The following job titles also refer to cylindrical grinder operator:

A high school diploma is generally required to work as a cylindrical grinder operator.

ISCO skill level is defined as a function of the complexity and range of tasks and duties to be performed in an occupation. It is measured on a scale from 1 to 4, with 1 the lowest level and 4 the highest, by considering:

• the nature of the work performed in an occupation in relation to the characteristic tasks and duties
• the level of formal education required for competent performance of the tasks and duties involved and
• the amount of informal on-the-job training and/or previous experience in a related occupation required for competent performance of these tasks and duties.

Cylindrical grinder operator is a Skill level 2 occupation.
