Embodiment

[0020] Embodiment: Accompanying drawing 1 is the schematic diagram of high-efficiency CNC milling electric discharge machining using simple long electrodes. The workpiece 1 is an engine turbine blade, and the material is a high-temperature heat-resistant alloy. The turbine blade is milled out by the method of high-efficiency discharge layered milling. space surface. This kind of high-efficiency milling EDM of rough machining is based on numerical control technology, using a simple hollow electrode 3 with a length-to-diameter ratio of 80:1, guided by a guide 4, and performing discharge layered milling on the workpiece 1. The simple hollow electrode 3 is a rod-shaped cylindrical electrode with a length of 1000 mm and a diameter of Φ6 mm. The center of the cross-section of the simple hollow electrode 3 is provided with holes. In electric discharge milling, the electrode rotates around its own axis, and at the same time, three cooling methods are used to cool the processing area, ...

Abstract

An efficient cooling the cutted fillings discharging method for efficient discharge milling features use of three cooling modes, that is, the workpiece is immersed in cooling liquid, the cooling liquid is sprayed out via hollow electrode in machining region for cooling and discharg the cutted fillings, and the cooling liquid is sprayed in working region via the the external channel of hollow electrode for cooling and discharging the cutted fillings.

Description

technical field [0001] The invention relates to a high-efficiency electric discharge milling process in the field of electric machining (such as electric arc and electric spark), in particular to a high-efficiency cooling and erosion removal method suitable for this process. Background technique [0002] In aerospace, military industry, gas turbine, mold and other fields, there are many parts of special materials that need to be processed, such as titanium alloy, high temperature heat-resistant alloy, stainless steel, etc. These materials have strong viscosity, poor thermal conductivity, and poor machinability. The processing efficiency is extremely low, and the tool cost is also very high, which seriously restricts the technological progress and development of these industries. [0003] In recent years, with the rapid development of electrical machining technology and technological level, the milling and forming processing technology for the above-mentioned special material...
