Claims

5. IN AN APPARATUS FOR MACHINING MATERIAL, IN COMBINATION, A SUPPORT MEMBER FOR SUPPORTING THE MATERIAL TO BE MACHINED;

A VIBRATORY MACHINING MEMBER HAVING A MACHINING SURFACE PORTION LOCATED OPPOSITE SAID SUPPORT MEMBER AND DEFINING WITH THE SAME A SPACE FOR THE MATERIAL;

MEANS FOR INTRODUCING A MACHINING SLURRY IN LIQUID CONDITION AT ATMOSPHERIC PRESSURE INTO SAID SPACE AND BETWEEN SAID MACHINING SURFACE PORTION OF SAID MACHINING MEMBER AND THE MATERIAL BEING MACHINED;

AND SUCTION MEANS COMMUNICATING WITH SAID SPACE FOR SUCKING THE MACHINING SLURRY OUT OF SAID SPACE FOR MOVING THE MACHINING SLURRY IN A SUBSTANTIALLY CONTINUOUS FLOW OVER SAID MACHINING SURFACE PORTION OF SAID MACHINING MEMBER AT A LESS THAN ATMOSPHERIC PRESSURE, WHEREBY THE VIBRATORY
