Description
Technical Field
The present disclosure relates to the field of material polishing, and more particularly, to a polishing tool having a coolant supply structure.
Background
With the constant development of WPC and 5G technologies of smart phones, glass materials have become the most popular material for making covers. More and more glass cover plates are designed with 3D shapes. In addition, wearable devices having a 3D shape, such as watches, AR glasses, and the like, are also increasing. During the manufacturing of such 3D shape designed cover plates, either the thermoforming method or the CNC machining method, a polishing step will need to be employed to remove surface defects formed during thermoforming or cutting marks caused in CNC machining. The conventional polishing process uses cerium oxide slurry, which removes slight surface defects, cutting marks, and polishes. For certain higher material removal requirements, such as deeper scratches, cutting marks, etc., a higher standard of cutting abrasives must be used for processing.
Diamond polishing films, cerium oxide polishing films, and the like have been developed as a substitute for slurry abrasives. One of the key applications of these polishing films is their use as polishing tools for CNC machines for grinding or polishing workpieces placed on CNC machines.
In practice, high-end CNC machines are typically equipped with a spindle internal coolant supply system that supplies sufficient coolant to the working area of the polishing tool through internal coolant holes to provide good cooling and lubrication of the working area while the polishing tool is performing a polishing operation. However, for many low speed CNC machines or other polishing machines, which typically do not have such an internal coolant supply system, coolant must be sprayed externally to the work area as the polishing tool performs the polishing operation. For large polishing tools or narrow polishing tools, the cooling conditions are not good. In this case, the central contact portion between the polishing head of the polishing tool and the workpiece does not have a sufficient coolant during polishing, which is a root cause of premature wear of the abrasive of the polishing film, heat distortion of the polished portion of the part, generation of orange peel, and the like.
Therefore, there is a need for a polishing tool that can perform well in low speed CNC machines or other polishing machines.

Detailed Description
Reference will now be made in detail to the present embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements throughout. The specific embodiments described below with reference to the drawings are illustrative and intended to illustrate the disclosure and should not be construed as a limitation on the disclosure.
According to an inventive concept of the present disclosure, there is provided a polishing tool including: a polishing head, and the polishing head is formed with a polishing surface; wherein the polishing head is provided with a cooling liquid chamber inside, and the polishing head is provided with a cooling liquid outlet penetrating from the cooling liquid chamber to the polishing surface, so that the cooling liquid flows from the cooling liquid chamber to the polishing surface via the cooling liquid outlet. According to the polishing tool provided by the embodiment of the disclosure, the cooling liquid supply structure is provided, and polishing cooling can be well realized on a low-speed CNC (computer numerical control) machine tool or other polishing machines.
Referring to fig. 1 to 4, a polishing tool 100 according to an embodiment of the present disclosure includes: a polishing head 10, a head cover 20, and a spindle 30. The polishing head 10 is formed with a polishing surface 11, a coolant chamber 12 is provided inside the polishing head 10, and the polishing head 10 is provided with a coolant outlet 13 penetrating from the coolant chamber 12 to the polishing surface 11, so that the coolant flows from the coolant chamber 12 to the polishing surface 11 via the coolant outlet 13.
Specifically, the polishing head 10 is provided with a plurality of coolant outlets 13, and the plurality of coolant outlets 13 are arranged in an array on the polishing surface 11. For example, in the embodiment shown in fig. 1, a plurality of coolant outlets 13 are arranged on the polishing surface 11 around the spindle 30 as a center. In other embodiments, the plurality of coolant outlets 13 may be arranged in other forms of arrays on the polishing surface 11. Here, the polishing surface 11 of the polishing head 10 mainly corresponds to a work area of the polishing tool 100 for performing a polishing operation on a workpiece to be polished. Further, the polishing tool 100 may further include a polishing film (not shown) covering the polishing surface 11. According to the embodiment of the present disclosure, the outer shape of the polishing head 10 matches the shape of the workpiece to be polished, and the polishing pad is covered on the polishing surface 11 as a working layer. Grooves or holes may be formed in the polishing pad to facilitate the coolant flowing from the coolant outlet 13 into the work area. When the polishing tool is rotated, the coolant is ejected from the coolant chamber 12 of the polishing head 10 via the coolant outlet 13 by centrifugal force into a work area in contact with the workpiece to be polished to perform cooling.
According to the embodiment of the present disclosure, as shown in fig. 1 to 3, the spindle 30 is connected to the polishing head 10 to rotate the polishing head 10. Specifically, the spindle 30 is connected to the polishing machine at one end and connected to the polishing head 10 at the other end to rotate the polishing head 10. For example, in the embodiment shown in fig. 1 to 3, the spindle 30 is disposed at the center of the polishing head and extends to the inside of the coolant chamber 12. Additionally, in one embodiment, the spindle 30 may be integrally formed with the polishing head 10; in another embodiment, the spindle 30 may also be detachably assembled to the polishing head 10.
According to the embodiment of the present disclosure, as shown in fig. 1 to 4, the cover 20 is detachably engaged with the polishing head 10 to cover the cooling liquid chamber 12, wherein the cover 20 is provided with a cooling liquid inlet 21 for connecting a delivery hose of a cooling liquid supply apparatus so that the cooling liquid enters the cooling liquid chamber 12 from the cooling liquid inlet 21. For example, in the embodiment shown in fig. 1 and 4, the head cover 20 is substantially circular, and a plurality of (two in the drawing) coolant inlets 21 are arranged around the center of the head cover 20. During the polishing operation of the polishing tool, the cover 20 covers the coolant chamber 12 of the polishing head 10 by its own weight, and holds most of the coolant into the working area corresponding to the polishing surface 11 via the coolant outlet 13.
According to the embodiment of the present disclosure, as shown in fig. 4, the surface of the head cover 20 facing the coolant chamber 12 is provided with an impeller 24. Specifically, a plurality of (three in the drawing) impellers 24 are arranged around the center of the head cover 20. During the polishing operation of the polishing tool, the polishing head 10 rotates together with the spindle 30, and relatively, the cover 20 rotates in the opposite direction with respect to the polishing head 10, so that the impeller 24 generates a pushing force to push the coolant in the coolant chamber 12 toward the coolant outlet 13, which helps to push the coolant toward the working area corresponding to the polishing surface 11 through the coolant outlet 13.
Further, according to the embodiment of the present disclosure, as shown in fig. 1 to 4, the head cover 20 is provided with the spindle through hole 22, the spindle through hole 22 is provided at a central position of the head cover 20, and the impeller 24 is arranged around the spindle through hole 22. The spindle 30 is disposed through the spindle through-hole 22 of the head cover 20. Further, the spindle 30 is provided with a flange 31, and the cover 20 is restrained by the flange 31, thereby preventing the cover 20 from being separated from the polishing head 10 in the axial direction of the spindle 30 during the polishing operation of the polishing tool. Further, the surface of the cover 20 facing the coolant chamber 12 is provided with a step 23, and the step 23 is in contact with the inner surface of the coolant chamber 12 to further restrict the cover 20 from being separated from the polishing head 10.
From the above, according to the polishing tool provided by the present disclosure, through the cooling liquid chamber disposed inside the polishing head and the cooling liquid outlet penetrating from the cooling liquid chamber to the polishing surface, the cooling liquid can directly flow from the cooling liquid chamber inside the polishing head to the polishing surface, so as to provide sufficient cooling liquid supply for the polishing surface (working area) of the polishing head, thereby ensuring that the working area on the low-speed CNC machine or other polishing machines can maintain sufficient cooling liquid supply without an internal cooling liquid supply system, further reducing the abrasive wear of the polishing film, and improving the polishing quality.
The foregoing detailed description of the present disclosure has been presented for purposes of illustration only and not limitation, and it will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the disclosure.
