Numerical control engraving and milling lathe for processing graphite electrode

Abstract

The invention discloses a numerical control engraving and milling lathe for processing a graphite electrode. The numerical control engraving and milling lathe comprises a lathe body (1), a working table (01), an X-axis system (02), a Y-axis system (03) and a Z-axis system (04). The lathe body below two sides of the working table of the numerical control engraving and milling lathe is formed into funnel slope shaped dust collection openings; an air draft channel communicated with the dust collection openings is formed in the center inside the lathe body; the outlet of the air draft channel is formed on the rear side face of the lathe body; a dust absorption fan is arranged on the rear side face of the lathe body; and the absorption end of the dust absorption fan is connected with the outlet of the air draft channel. During working, the dust absorption fan gathers and absorbs graphite dust produced by milling through the dust collection openings and the air draft channel, and sends the graphite dust into a water-filtering dust-removal pot through a hose for wetting, precipitation and integrated processing. By the technical scheme, the shortcomings that the dirt pollutes the environment, the dust removal efficiency is low, and the cooling liquid consumption and the production cost are high are avoided; and by the dry-type dust absorption mode and the water-filtering dust removal mode, the processing of the graphite electrode fulfills the aims of low cost and high efficiency in dust removal.

Description

technical field [0001] The invention relates to a numerically controlled engraving and milling machine tool, in particular to a numerically controlled engraving and milling machine tool used for machining graphite electrodes by engraving and milling. Background technique [0002] Graphite is a non-metallic material with excellent electrical conductivity. Graphite electrodes are used for EDM mold cavities. A large amount of graphite dust will be produced in the process of engraving, milling and cutting graphite electrodes with ordinary CNC engraving and milling machine tools. And the short circuit of the control system is out of control; the existing technology uses a large amount of coolant to wet and wash the graphite dust generated by the cutting process to prevent the graphite dust from flying around; the dust and dirt condensed on the machine tool are difficult to remove in this method, and the coolant is difficult to recycle. This leads to large consumption, high cost,...

Problems solved by technology

A large amount of graphite dust will be produced in the process of engraving, milling and cutting graphite electrodes with ordinary CNC engraving and milling machine tools. and the control system short-circuit out of control; the existing technology uses a large amount of coolant to wet and wash the graphite dust generated by the cutting process to prevent the graphite dust from flying around; in this method, the dust and dirt condensed on the machine tool are not easy to remove, and the coolant is difficult to recycle. It leads to large consumption, high cost, and low efficiency. Therefore, the existing technology has the problems and deficiencies of mud pollution, low dust removal efficiency, high cooling fluid consumption, and high cost.
