tumbling machine parts
Various parts of a tumbling machine, such as a deburr tub, tumbling barrel, tumbling compound and steel media ceramic polishing pins, their qualities and applications.
Tumbling machine operators set up and operate tumbling machines, often wet or drie tumbling barrels, designed to remove excess material and burrs of heavy metal workpieces and precious metals and to improve surface appearance, by rotating the metal pieces in a barrel together with grit and potentially water, allowing for the friction between the pieces mutually and with the grit to cause a rounding, smooth effect.

The most optimal rotation or cycle time and over-all quality of a tool or a machine's processes.
quality standards
The national and international requirements, specifications and guidelines to ensure that products, services and processes are of good quality and fit for purpose.
types of lubricants
Types of substances whose main function is to reduce friction between parts or surfaces in mutual contact such us oil-based, grease-based, penetrating or dry lubricants. They facilitate uninterrupted movement between machinery parts. Based on the type of lubricant, they can also perform other functions such as power transmission or heat regulation.
types of metal

monitor moving workpiece in a machine
Monitor the processing of a workpiece in motion, such as a piece of metal or wood moved linearly over a static manufacturing machine.
perform test run
Perform tests putting a system, machine, tool or other equipment through a series of actions under actual operating conditions in order to assess its reliability and suitability to realise its tasks, and adjust settings accordingly.
remove inadequate workpieces
Evaluate which deficient processed workpieces do not meet the set-up standard and should be removed and sort the waste according to regulations.
remove processed workpiece
Remove individual workpieces after processing, from the manufacturing machine or the machine tool. In case of a conveyor belt this involves quick, continuous movement.
spot metal imperfections
Observe and identify various kinds of imperfections in metal workpieces or finished products. Recognise the best fitted manner of fixing the problem, which could be caused by corrosion, rust, fractures, leaks, and other signs of wear.
supply machine
Ensure the machine is fed the necessary and adequate materials and control the placement or automatic feed and retrieval of work pieces in the machines or machine tools on the production line.
tend tumbling machine
Tend a machine designed to smoothen metal or stone surfaces by having the different pieces rub against each other inside a tumbling barrel, monitor and operate it according to regulations.
troubleshoot
Identify operating problems, decide what to do about it and report accordingly.
wear appropriate protective gear
Wear relevant and necessary protective gear, such as protective goggles or other eye protection, hard hats, safety gloves.
