The stable processing chip magnetic roller chip conveyor for waste industrial CNC machine tools utilizes the rotation of magnetic rollers to transfer chips step by step between each magnetic roller, in order to achieve the purpose of conveying chips. This machine is developed based on a magnetic chip conveyor. It compensates for the performance and structural deficiencies of magnetic chip conveyors in certain aspects of use. Suitable for conveying powdered chips in wet machining, and more suitable for chip removal when chips and cutting fluids contain a lot of oil stains.
