Testing machine for analysing shot performances.

摘要

The present invention relates to a device capable of reproducing shot performances, and consists of a table drill without cooling, whose tool is a straight regular cylinder that with its rotary motion erodes blocks of stone, which it rubs from above in combination with a certain quantity of shot deposited between the two. In this way, by studying this and the sand formed, precise data are obtained of its performance in order to achieve maximum productivity and quality. The machine has three stoppage systems, one manual and two programmable and automatic. The latter can either be by timing, where the tool ceases to rotate when the indicated time has elapsed, or by rotations where the tool ceases its activity when the programmed turns have been completed.
