Description

Technical Field

[0001] The utility model relates to the technical field of chip removal of numerically controlled machine tools, in particular to a magnetic chip removal system for machine tools. Background Art

[0002] When large CNC gear milling machines are working, a large amount of processing iron chips will be generated. At present, a magnetic chip removal system is installed under the workbench of the gear milling machine for chip removal. The magnetic chip removal system removes chips by installing a strong magnetic block on the chain. The strong magnetic block is located on the lower side of the top plate. The iron chips fall on the top plate. As the chain rotates, the strong magnetic block rotates with it, thereby discharging the iron chips on the upper side of the top plate.

[0003] When the gear milling machine is working, it will use coolants such as oil or emulsion to cool the machining tool. Part of this coolant will flow into the magnetic chip removal system and concentrate between the top plate and the side plate of the horizontal section of the magnetic chip removal system. At present, a drainage pipe port is set on the side plate, and a hose is installed on the drainage pipe port to discharge the concentrated coolant. However, since the magnetic chip removal system itself is installed at the bottom of the gear milling machine workbench, the height difference between the drainage pipe port and the ground is small, and the drainage pipe port is easily blocked by iron chips, resulting in poor drainage effect.
