GRINDING/POLISHING/CLEANING MACHINE FOR SMALL CASTING

摘要

PROBLEM TO BE SOLVED: To provide a grinding/polishing/cleaning machine for small castings that can minimize castings with burrs left untrimmed. SOLUTION: A grinding/polishing/cleaning machine 10 for small castings has in its casing 12 a fixed plate 18 with work rotating ribs 24 set at constant pitches and a rotary roller 20 with a peripheral screw tooth 28 both arranged in an adjacent relation to replace a conventional apron conveyor. The screw tooth 28 of the rotary roller 20 and the fixed plate 18 function as a screw conveyor, which feeds work 30 one at a time. The work 30, when fed, is rolled over the work rotating ribs 24 or is rotated at random, so that a blast material 14 can be directed against the work 30 oriented in various directions. Products with burrs left untrimmed appear to a minimal degree.
