10516  Set up a bench and level a scaiffe for polishing diamond gemstones  Level 2  NQF Level 02  Complete 

PURPOSE OF THE UNIT STANDARD 
This unit standard is useful for people who intend following a career in the diamond processing sector and who are required to set up a bench and level a scaiffe in order to polish diamond gemstones.

Learners credited with this unit standard are able to:
  • Identify the equipment and tools required to set up a bench and level a scaiffe for polishing diamond gemstones and describe their application.
  • Set up and align a bench and a scaiffe.
  • Conduct post set up activities.

    The skills, knowledge and understanding demonstrated within this unit standard are essential for social and economic transformation and contribute to the upliftment and economic growth of the mining and minerals sector, particularly in the aspect of beneficiation.

    This unit standard is intended to promote general skills, knowledge and understanding of the diamond processing industry in the mining and minerals sector in order to ensure knowledgeable and informed workers. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    It is assumed that learners are already competent in:
  • Communications and Mathematical literacy at NQF Level 1. 

  • UNIT STANDARD RANGE 
    The scope and context applies to the conversion of rough diamond gemstones into cut and polished diamond gemstones for sale into local and international markets.

    ASSESSMENT CRITERION 1 
    Appropriate personal protective clothing and equipment is selected and applied according to required standards of occupational health and safety. 

    ASSESSMENT CRITERION 2 
    A bench is set up and checked to be level. Adjustments are made, in line with workplace specific procedures, until the bench is level. 

    ASSESSMENT CRITERION 3 
    The drive mechanism is checked to provide a constant rate of revolution. Remedial action is taken in line with workplace specific practices to adjust the rate of revolution as required. 

    ASSESSMENT CRITERION 4 
    A scaiffe is checked to ensure it is prepared for use, set in the bench and adjusted to be level with the bench. 
    ASSESSMENT CRITERION RANGE 
    Candidates must demonstrate the ability to prepare either spindle or non-spindle types of scaiffe.
     

    ASSESSMENT CRITERION 5
