Numerical control machine tool metal cutting method

Abstract

The invention provides a numerical control machine tool metal cutting method. The numerical control machine tool metal cutting method comprises the steps that (1) a cooling water spray branch and a lubricating oil spray branch are arranged, wherein the cooling water spray branch is used for spraying cooling water, the lubricating oil spray branch is used for spraying lubricating oil, and the lubricating oil comprises plant grease, water, polyethylene glycol, diethylene glycol, triethylene glycol, organic acid and an oxidizing agent; (2) a cooling water spray nozzle and a lubricating oil spraynozzle are arranged on the two sides of the axial movement axis of a cutting cutter correspondingly and are mutually symmetrical about the axis; (3) when a metal part is machined, the cooling water spray nozzle and the lubricating oil spray nozzle simultaneously spray corresponding liquid to a rake face of the cutting cutter and a cut face of the metal part. According to the numerical control machine tool metal cutting method, through adjustment of the spray angles of cooling water and lubricating oil, atomizing efficiency of the oil and the mixing ratio of the oil and water mist are increased, the good lubricating and cooling effects are achieved, generation of burrs is also restrained, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of CNC machine tool cutting operations, in particular to a metal cutting method for a CNC machine tool. Background technique [0002] When CNC machine tools are used to cut objects, lubricants are needed to lubricate the cutting surface, and at the same time, cooling water is sprayed to cool down, so as to cool the tools and parts, and avoid deformation and cracks of the tools and parts under high temperature. [0003] The spraying angle of lubricant and cooling water directly affects the cooling and lubricating effect of the tool and parts surface, and there is no better adjustment method in the prior art. [0004] In addition, metal parts are prone to burrs during processing. These burrs need to be removed by grinding before subsequent processing of metal parts. When there are too many burrs, it is easy to reduce the production efficiency of parts. Contents of the invention [0005] Purpose of the inven...
