Cutting tool

Abstract

The invention discloses a cutting tool which comprises a base which comprises a fluid cavity for containing fluid; the operation table is arranged on the base; the cutting mechanism comprises a driving part and a cutting part, the driving part drives the cutting part to rotate, and at least part of the cutting part protrudes and penetrates through the operation table; the drainage cover is detachably arranged in the fluid cavity and comprises a main shell part arranged around the periphery of the cutting piece, the fluid can flow along the inner wall of the main shell part, and the inner wall of the main shell part is arranged in an inclined or bent mode relative to the bottom wall of the fluid cavity.

Description

technical field [0001] The invention relates to an electric tool, in particular to a cutting tool. Background technique [0002] The traditional cutting tool includes a cutting piece that can cut the workpiece and a workbench. During the cutting process, the cutting piece will generate heat and become hot. The piece is partially immersed in the cooling liquid, during the cutting operation, the cutting piece rotates and the heat is carried away by the cooling liquid, [0003] During the use of the cutting tool 100 , due to the high-speed rotation of the cutting member 220 , the cooling liquid in the fluid chamber 111 is easily taken away, and the cooling liquid will be splashed by centrifugal force during the process of being driven away by the cutting member 220 . On the one hand, the splash of coolant will pollute the working environment, and the thrown coolant cannot be recovered, resulting in low efficiency of coolant use, and frequent addition of coolant is not conduciv...

AI Technical Summary

Problems solved by technology

[0003] While the cutting tool 100 is in use, due to the high-speed rotation of the cutting part 220, the coolant in the fluid chamber 111 is easily taken away, and the cooling liquid will be splashed by the centrifugal force when it is driven away by the cutting part 220. On the one hand, the splashing of coolant will pollute the working environment, and the thrown out coolant cannot be recycled, resulting in low efficiency of coolant use, and the need to frequently add coolant is not conducive to improving the user experience; on the other hand, the splashed cooling After the liquid and cutting debris are mixed, it is easy to contaminate the surface of the workpiece and cover the cutting line, which affects the user's operation line of sight and affects the cutting accuracy.

[0004] In order to solve the above problems, at present, baffles or bosses that partially surround the cutting piece are set at the axial ends of the cutting piece in the fluid chamber to slow down the splashing phenomenon when the coolant is taken away from the liquid surface. The above method has been verified. Can only slightly slow down the splash phenomenon, the effect is not significant
