Problems solved by technology

[0005] To sum up, the severe friction between the chip and the tool surface has always been a problem that is difficult to solve in the cutting process. Although the existing methods can improve the friction state between the chip and the tool surface in a short time and reduce the contact area between the two, the chip and the tool surface The long-term friction between the tools will cause the wear of the tool surface, and eventually cause the tool to fail

Embodiment 2

[0035] This embodiment discloses a cutting machine tool, which is equipped with the electromagnetic force-assisted cutting device described in Embodiment 1, the tool holder is connected with the tool feeding mechanism of the cutting machine tool, and the machine tool also includes a bed, a power system, Structures such as the main shaft all adopt the structure of the existing cutting machine tool, and its specific structure will not be described in detail here.

Embodiment 3

[0037] This embodiment discloses a working method of a cutting machine tool: the workpiece 1 is fixed on the main shaft of the cutting machine tool, the main shaft of the cutting machine tool drives the workpiece to rotate, the tool feeding mechanism of the cutting machine tool drives the cutting tool to move, and the workpiece is cut. While the cutting tool is processing the workpiece, the DC power supply is working, and the DC power is passed into the electromagnetic coil. The staff uses the control system to send instructions to the current controller, and uses the current controller to adjust the current size of the electromagnetic coil. In this embodiment , the current passed into the electromagnetic coil is 0A-30A, which can be set by those skilled in the art according to actual needs.

[0038] After the electromagnetic coil is fed with current, a magnetic field is generated, and the magnetic field generates a magnetic field force away from the direction of the cutting to...

Abstract

The invention relates to an electromagnetic force assisted cutting device, a cutting machine tool and a method, the electromagnetic force assisted cutting device comprises a cutting tool and an electromagnetic coil which can move synchronously, the electromagnetic coil is connected with a direct-current power supply, and the electromagnetic coil is configured to generate magnetic field force acting on cut chips and enabling the cut chips to be far away from the cutting tool after being electrified. By the adoption of the cutting device, the service life of the cutting tool can be effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of mechanical cutting processing equipment, in particular to an electromagnetic force-assisted cutting device, a cutting machine tool and a method. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] With the intensification of environmental pollution, green manufacturing has become a current research hotspot. Dry cutting can effectively avoid the use of cutting fluid, but there are disadvantages such as severe tool wear and low service life in the dry cutting process. One of the main forms of tool failure is the contact and friction between chips and the tool surface leading to tool wear. [0004] At present, the methods to solve the problem of tool wear mainly include tool coating, micro-textured tools and self-lubricating tools. Tool coatings are divided into two categories: hard ...
