Abstract

The invention provides a turning machining device used for a machine tool. The turning machining device comprises an online electric pulse processing device used for performing electric pulse processing on a to-be-machined region of a workpiece to improve the machining performance of the to-be-machined region, the online electric pulse processing device comprises a pulse power supply and an electrode, the pulse power supply comprises a positive electrode and a negative electrode, one of the positive electrode and the negative electrode is electrically connected with the workpiece, and the electrode can make contact with the surface of the to-be-machined region of the workpiece and is electrically connected with the other of the positive electrode and the negative electrode. By employing the turning machining device, the acting force required by the turning can be reduced, the quality of the machining surface is improved, the tool loss is reduced, the structure is simple, and the machining cost is low.

Description

technical field [0001] The present invention generally relates to the field of mechanical processing, and specifically relates to a turning device. Background technique [0002] With the development of science and technology, materials such as nickel-based superalloys, titanium alloys, and alloy die steels have gained a lot of attention in the fields of aviation, aerospace, medical, atomic energy, electronics, machinery, metallurgy, chemical industry, nuclear reactors, and petrochemicals due to their excellent performance. It is widely used and has brought huge social and economic benefits. However, these materials are typical difficult-to-machine materials, and it is very difficult to process them. For example, due to its low thermal conductivity, high strength and toughness, nickel-based superalloys have high resistance to plastic deformation and serious chilling and hardening during cutting. The relative processability is only 6%-20% of 45# steel, and the tool wear is se...
