[0002] With the development of modern industry, the demand for high-precision parts is growing. Grinding, as an important processing method, has an irreplaceable position in the manufacture of high-precision parts. In order to meet the market demand for high-precision parts, multi-axis CNC precision grinding devices have come into being. This device adopts multi-axis control technology and can achieve more complex processing trajectories and higher processing accuracy. It can accurately control multiple coordinate axes through the CNC system, so that the grinding tool moves along a predetermined trajectory in three-dimensional space, thereby achieving high-precision grinding of parts. Since the multi-axis CNC precision grinding device will generate a large amount of waste slag during processing, the waste slag will fly inside the device, but most of the existing multi-axis CNC precision grinding devices lack certain blocking components, which easily leads to the accumulation of waste slag in the corners, making it difficult to clean up the waste slag, greatly reducing the cleaning efficiency of the device. In order to solve the shortcomings of the prior art, we propose a multi-axis CNC precision grinding device. Utility Model Content

However, most of the existing multi-axis CNC precision grinding processing devices lack certain blocking components, which easily leads to the accumulation of waste slag in the corners, making it difficult to clean the waste slag, greatly reducing the cleaning efficiency of the device.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model provides an automatic material pushing assembly, including a motor, which is started to drive the bidirectional threaded rod to rotate. The rotation of the bidirectional threaded rod drives two fixing bars connected by threads on its outer surface to move relative to each other, thereby driving the two material pushing members to slide relative to each other at the bottom of the inner cavity of the grinding chamber. By using the above structure, the two material pushing members are driven to move relative to each other by turning on the motor, which can avoid the accumulation of waste residues generated by the grinding mechanism during processing in the corners, making it easier to clean up the waste residues, thereby greatly improving the cleaning efficiency of the device.

The waste residue falls into the interior of the waste frame through the through holes on the lower outer surface of the material guide chamber, and the water will reach the bottom of the inner cavity of the material guide chamber. By utilizing the above structure, the separation of waste residue and water is achieved through the screening component and the waste frame, which greatly improves the recovery efficiency of the waste residue and also avoids the waste of water resources.

[0025] Among them, the waste collection component 3 includes a material guide chamber 31, a waste frame 32 is attached to the lower outer surface of the material guide chamber 31, sliding blocks 33 are welded to the outer surfaces of both sides of the waste frame 32, a support column 34 is fixedly installed at the bottom of the inner cavity of the material guide chamber 31, and a screening component 35 is fixedly installed on the outer surface of the support column 34.
