DESCRIPTION

Technical Description

The lever shears model forms part of the extensive GUNT course providing an introduction to technical drawing. The didactic approach involves teaching the systematic and transferable learning matter based on an operational mechanism. 

The lever shears model can be considered to be a project enabling interdisciplinary, action-oriented teaching. As well as the primary technical drawing focus of teaching, other topics that can be covered include machine elements, assembly processes, and manufacturing technology.

TZ 200.07 presents a hand-operated lever shears  which can be used to cut thin metal sheets.

All parts are precision-manufactured on CNC machines. The surfaces of the steel parts have a gunmetal finish to prevent corrosion.

Comprehensive and well-structured instructional material supports wide-ranging use of the model in technical training.

Optimal learning is established when one model is used with two/three students.
