Machine tool chip conveyors are used to carry away the metal chips produced by machine tools. They use heavy-duty steel link belts usually arranged in a serpentine shape. The Machine Tool Chip Conveyor Learning System adds to Mechanical Drives 1 Learning System to teach skills related to machine tool chip conveyors. Students will learn industry-relevant skills related to this new topic including operation, installation, alignment, maintenance, and troubleshooting. Machine Tool Chip Conveyor Learning System uses industrial quality components to help students become better prepared for what they will encounter on the job and to withstand frequent student use. The Machine Tool Chip Conveyor Learning System includes an operational floor-standing chip conveyor; student learning materials for both theory and lab, and teachers guide.

The Machinary Diagnostic System permits vibration measurement exercises whereby readings can be taken from different points on the apparatus and at different motor speeds. The Machinary Diagnostic System can be used to simulate certain types of damage and investigate its effects on the vibration spectrum. Balancing of rigid rotors and alignment of shafts can also be practiced. Users can also complete exercises from purposefully induced faults (measurement of vibration displacement, velocity and acceleration in the time/frequency range).
A speed controller and tachometer display are supplied to allow the accurate controlling and displaying of the speed of the motor. The base frame, with integral grooves allows the elements of the apparatus to be moved and adjusted into position accurately. The Machinary Diagnostic System allows the quick and easy mounting of the key component parts. The key components of the base unit are the mechanical elements (i.e. motor, bearing blocks and shaft with rotors).

Features:
The sheet metal is clamped between the two by anelectromagnet capable of clamping with a force range of between 3-10 tons. The fundamental Principle of the Magnetic Bending Machine is that it uses electromagnetic, rather than mechanical, clamping system. Rotating the bending beam then forms the bend. The sheet is bent around thefront edge of the clamping bar. The machine consists of a long electromagnet with a steel clamp bar located above it. They have application in many ways with fourvarious sets clamping bars.
