Iron-based material electric field assisted processing machine tool and processing method

Abstract

An electric field assisted processing machine tool for iron-based materials and a processing method. The iron-based material electric field assisted processing machine tool comprises a spindle, a mounting piece, a diamond tool and a power supply device. The diamond tool is mounted on the spindle, the spindle drives the diamond tool to rotate, and the mounting piece is opposite to the spindle. , the mounting piece is used to install the workpiece, and the power supply device is used to supply a changing current to the workpiece, so that the electrons in the workpiece are in a disordered state. The electric field-assisted processing machine tool and processing method for iron-based materials provided by the present invention, by setting a power supply device to supply a variable current to the workpiece, so that the electrons in the workpiece are in a disordered state, and the pairing of electrons is suppressed, so as to achieve the effect of suppressing the graphitization of diamond tools. For the purpose, the solution has a better suppression effect, can be applied to long-distance cutting, does not require complex process requirements and expensive equipment, and has low cost.

Description

technical field [0001] The invention belongs to the field of iron-based material processing, and in particular relates to an electric-field-assisted processing machine tool for iron-based materials and an electric-field-assisted processing method for iron-based materials. Background technique [0002] The affinity between iron-based materials and carbon elements is extremely strong, so when diamond tools are used to cut iron-based materials, the diamond tools will suffer catastrophic wear, resulting in the cutting edge of the diamond tools unable to maintain the original sharpness and processing. Optical-level surface roughness, which will bring high processing costs for ultra-precision machining, and it is impossible to replace iron-based materials with turning instead of grinding. In order to suppress the wear of diamond tools, the current processing aids include nitriding on the surface of the workpiece, ion implantation of diamond tools, and ultrasonic vibration assistan...

Problems solved by technology

However, diamond tool wear is only reduced to a certain extent but not completely suppressed. With the increase of cutting time or cutting distance, the signs of diamond graphitization and built-up edge still exist.

[0006] Although the above three solutions have suppressed the wear of diamond tools cutting iron-based materials to a certain extent, the suppression effect is still unsatisfactory, and cannot be applied to long-distance cutting, all of which require complex process requirements and expensive equipment, resulting in higher costs. high
