DESCRIPTION

Technical Description

The kit contains all the parts required to assemble a functional lever shears. The parts are clearly laid out on a base plate. They are grouped into individual assembly sequences. The base plate is covered with a  transparent cover panel on which a graphical representation of the assembly structure is printed. The graphic symbolises standard and production parts, and represents fixed and moving connections differently.

All parts are precision-manufactured on CNC machines and feature standard engineering tolerances and surface finishes. The surfaces of the finished parts have a gunmetal finish to prevent corrosion. 

Multiple trays are stackable, providing for space-saving storage.

The kit is ideally deployed for student exercises during teaching, with two/three students able to work with each kit.

The comprehensive and clearly structured instructional material is laid-out in line with modern principles and is of great help with lesson preparation.
