The present invention provides a milling tool (1) for a wellbore, comprising a milling section (2) and a metal cuttings removal section (3), the milling section (2) comprises radially arranged milling elements (4); and the metal cuttings removal section (3) has a first end (5) and a second end (6) and comprises a cylinder-shaped magnetic element (7), a rotation generating device (8) and a helix-shaped longitudinal guide element (9), wherein the first end (5) is connected to the milling section; the helix-shaped longitudinal guide element (9) is arranged around the cylinder-shaped magnetic element (7); the rotation generating device (8) is operably connected to the cylinder-shaped magnetic element (7) or the helix-shaped longitudinal guide element (9); wherein the cylinder-shaped magnetic element and the helix-shaped longitudinal guide element (9) are rotatable relative to each other around a common centreline (C), and configured such that metal cuttings accumulating on the cylinder-shaped magnetic element during use is guided by the helix-shaped longitudinal guide element towards the second end (6) of the metal cuttings removal section when the rotation generating device is operated.

The invention relates to a liquid separating device capable of separating liquid from metal chip materials. Four positioning guide columns and a motor are installed on a base. A spring respectively sleeves each positioning guide column. The upper end of each positioning guide column is sequentially provided with a stander and a circular outer barrel. A bearing seat with a bearing A and a bearing B in the middle part is installed in the middle part of the stander, and a main shaft is installed between the bearing A and the bearing B. The lower part of the main shaft is connected with the motor through a triangular adhesive tape. A porous circular barrel is fixedly installed on the main shaft. A porous movable suspension barrel is movably installed in the middle of the porous circular barrel, and the bottom of the porous movable suspension barrel is provided with a movable soleplate. A suspension ring is installed on the porous movable suspension barrel. Both the porous circular barrel and the porous movable suspension barrel are provided with a plurality of liquid holes. A liquid holding barrel is arranged below a liquid flow-out pipe of the circular outer barrel. When the liquid separating device is used for separating the liquid from the metal chip materials, less vapor and less smoke, which are mixed with hydrocarbon, are produced, the heat energy is not wasted, the environment is not polluted, and the body health of the operation personnel is not damaged. The liquid separating device can be used for recycling the mixed liquid of cutting liquid and lubricating oil and for further processing and utilizing the metal chip materials.

The invention relates to an abrasion detection device of a mixed type rotary cutter, which belongs to the field of mechanical processing. In the invention, the abrasion image of the cutter is obtained by utilizing an area array type CCD industrial camera and is transmitted to an upper computer by a USB. In order to realize the multi-angle shooting of the cutter, the camera has three degrees of freedom aggregately: a translation platform realizes the focusing function of the camera to the cutter to be detected, a horizontal rotation platform realizes the multi-direction shooting of the camera to the cutter, and a pitching rotation platform realizes the shooting of the camera to a plurality of angles of the cutter. In order to realize the measurement of the abrasion of the cutter in a processing process, the design has the function of water prevention and can prevent cutting fluid and metal swarfs from entering the inside of the device.

The invention relates to the field of numerical control machine tools, and discloses a front-end high-efficiency slag removal protection device for a coolant circulation pump of a numerical control machine tool, which includes a first water inlet pipe, and the water inlet end of the first water inlet pipe is located at the bottom of the coolant water storage tank Above, the water outlet end of the first water inlet pipe communicates with the lower part of the slag removal box, and the first water inlet pipe communicates with the lower part of the slag removal box through a one-way valve, and one end of the one-way valve extends to the slag removal box internal. A liquid outlet hopper with a spiral structure guide plate is installed inside the slag removal box, so that the cooling liquid flowing out of the liquid outlet hopper flows into the centrifugal cavity in a rotating state. Due to the large inner diameter of the centrifugal cavity, the cooling liquid is here The flow velocity at the center decreases, and the heavy metal chips are gradually brought to the inner wall side of the centrifugal chamber, and fall into the bottom of the slag removal box along the gap between the inner wall of the cone and the outer wall of the liquid outlet hopper under the action of its own weight. , so as to realize the separation of metal chips.
