Performance tests of an abrasive cut-off systems for the finishing of high-precision casts

Fedoryszyn A., Meksa W. T., Woźnicki G.

Archives of Foundry Engineering

2008

Vol. 8, iss. 3

205-208

The paper summarizes the performance data of a newly designed and engineered grinding and cut-off system. The machine is used for separation of models manufactured by the investment casting method. The machine comprises the following units: - base supporting other assemblies and elements: abrasive disc holder and drives; this solution enables an easy replacement and access to holding elements while a belt transmission allows the disc rpm to be varied, - mechanism moving the spindle in the horizontal, hence the abrasive disc position with respect to the batch can be precisely controlled, depending on the cast position and their shape, - holding and positioning-control of the batch to enable the fore and aft movements and rotations, - guide systems ensuring the travel of the batch in the specified direction and adjusting the travel speed to the required cutting rate, - centering, control, exhaust system, housing. Extensive tests were performed, including the tests of operating parameters of abrasive discs depending on the cast material, cyclograms of the applied treatment are obtained accordingly.
