Dispositivo con filtro por campo magnético, para retirar polvo metálico en maquina CNC en la industria metalmecánica

Abstract

Objective: Implement the "filter by magnetic field" and be able to improve the quality of the geometric and visual pieces, returning the properties to the refrigerant (oil) by removing the impurities, and thus being able to improve the efficiency of the machining through this project. Methodology: The device is integrated by a magnetic field filter that was designed to remove the metallic microparticles found in the refrigerant fluid and thereby reduce the geometric and dimensional variation in the specifications of precision machined parts in CNC. A filtering system for the burr of the refrigerant oil is applied by means of an electromagnet. The purpose of this project is to reduce the amount of Scrap by variation produced in the final measurements by premature wear of the cutting tool edge generated by these metal particles suspended in the cooling oil even after being filtered conventionally. This project also aims to extend the useful life of the tools (inserts, bits and shanks), since the durability of the tools is reduced and when they lose the edge they fracture prematurely producing scrap pieces. Contribution: The implementation of the filter would reduce the defect of parts marked by residues inside the refrigerant by 90 percent.
