Deep hole machining device

Abstract

The invention discloses a deep hole machining device, which comprises an electrolyte tank, a high-pressure liquid pump, a cathode, an insulating tube and a power source, wherein the output end of the electrolyte tank is connected with the input end of the high-pressure liquid pump; the output end of the high-pressure liquid pump is connected with the insulating tube; the cathode is arranged in the insulating tube, and is connected with the input end of the power source; and the output end of the power source is connected with a workpiece. By the device, electrolyte with certain pressure flows through a tool electrode and the workpiece at a high speed and washes away an electrolysate dissolved from an anode, and a deep hole is directly formed through one-time feeding, so the production efficiency is high. The device is compact in structure, ensures that a machined surface does not have any residual stress, fins, burrs, degenerative layers and the like, can machine metal materials with any hardness, strength and toughness, and is high in surface roughness and machining accuracy.

Description

technical field [0001] The invention relates to a deep hole processing device. Background technique [0002] At present, when processing deep holes with a depth-to-diameter ratio of L / d≥100, such as cylinder holes, axial oil holes of shafts, rocket bodies and barrels of various artillery, etc. Due to the poor heat dissipation conditions of the tool and the difficulty in chip discharge, the cutting temperature rises and the durability of the tool is reduced. Moreover, due to the high machining accuracy and surface quality required, the machinability of some processed materials is poor, which is often a production tool. Therefore, during production, the tool holder is often limited by the diameter of the hole, the diameter is small and the length is large, making chip removal difficult, easy to cause poor rigidity, low strength, and vibration, ripples, and taper generated during cutting. Straightness and surface roughness of deep holes. Contents of the invention [0003] P...
