However, in processing operations using such a conventional dust mouth-shaped dust suction port 1,
Since the dust suction port 1 is widened to improve work efficiency, the wind speed at the work point is slow, and due to the rotational inertia of the cutting equipment, dust tends to fly off and cannot be sucked into the suction pipe 4, resulting in dust scattering. It was hot. In order to prevent this dust from scattering, it is possible to increase the exhaust air volume and increase the wind speed at the work point to increase suction efficiency, but there is an energy limit and it is not possible to increase the air volume unnecessarily. .

被加工物の加工に適用することもできる。 When using the processing dust collection box configured as described above, the negative pressure source is activated, the top cover 14 is opened, and the workpiece 28, such as a denture or denture base, is inserted into the box 11. On the other hand, the working insertion hole 1
6. Insert one hand (left hand) into the workpiece 28.
on the other hand, insert the tip of the pen holder type machining tool 29 held and activated in the other hand (right hand) through the tool insertion hole 17, and insert the tip of the workpiece into the tool insertion hole 17 at a location close to the tool insertion hole 17. 28 is cut or polished using a processing tool 29. The reason why the cutting or polishing process is performed at a location close to the tool insertion hole 17 is that if the process is performed at a location where the wind speed toward the exhaust hole 23 is particularly high, dust will not be scattered and will be efficiently sucked into the exhaust hole 23. This is because such a location is close to the tool insertion hole 17 in the box 11. That is, the diameter of the tool insertion hole 17 into which the processing tool 29 for cutting or polishing the workpiece 28 is inserted may be small at 40φmm, but if the diameter of this hole is made large, the tool insertion hole 17
As a result, the efficiency of sucking dust into the exhaust hole 23 decreases. Therefore, since the diameter of the tool insertion hole 17 is set to be the same as or slightly larger than the diameter of the exhaust hole 23 as described above, the wind speed passing through the tool insertion hole 17 is high. According to this embodiment, the workpiece 28 can be machined in this high wind speed area, so if the process is performed here, the dust generated by this process will be sucked into the exhaust hole 23 without being scattered. As a result, dust can be collected completely and air pollution can be prevented, which is very desirable in terms of environmental hygiene. Furthermore, the heat generated during machining of the workpiece 28 is cooled by the high-speed wind in this part, so the cooling effect is great. Further, according to this embodiment, the top lid 14 of the box 11 can be opened and closed, so the box 11 can be opened and closed.
It is convenient to be able to put in and take out the workpiece 28 from the top of the paper sheet 1, and since the bottom member 24 is removable, the bottom member 24 can be removed after processing work and the dust that has fallen on the paper sheets 26 can be removed immediately. The inside of the bottom member 24 and the inside of the box 11 can be easily cleaned. Further, according to this embodiment, the bottom member 24 is connected to the paper sheet 26 placed on it.
is loosely fitted to the lower end of the side wall of the box 11 with its outer peripheral end protruding from the edge 25 of the bottom member 24, so when processing precious metals such as gold crowns, it is necessary to It is possible to perform the processing by adjusting the air volume, remove the bottom member 24, take out the paper sheets 26 on the bottom member 24, and reliably collect all the precious metal processing waste that has fallen on the paper sheets 26, It can be used to recycle expensive resources. Further, in the embodiments described above, the present invention is applied to the processing of dentures or denture bases, but the present invention is not limited thereto, and can also be applied to the processing of other workpieces, such as deburring cast products.

As explained above, according to the present invention, only one hand needs to be inserted into the box to carry out processing, so it can be made smaller, and the workbench (technician) The area occupied by the machine (table) can be significantly reduced, and the hand holding the processing tool can move freely, greatly improving work efficiency. Also, the diameter of the tool insertion hole is the same as or slightly larger than the diameter of the exhaust hole, so
The wind speed passing through the tool insertion hole becomes high, and the wind speed passing through the machining section directly in the tool insertion hole can be made much faster than before with less energy, thereby reducing the leakage of dust to the atmosphere. It is possible to reliably prevent this and obtain sufficient dust suction efficiency, and since the wind speed in the processing section is thus high, the cooling effect of the processing section can be greatly improved. Furthermore, since the box is made of transparent material, you can see the workpiece and tools directly, so you can work more reliably, and the top lid of the box can be opened and closed, so you can view the workpiece from the top of the box. It is convenient to put in and take out, and the bottom member covered with paper sheets is removable, so by removing the bottom member, you can quickly collect dust that has fallen on the paper sheets and remains. In addition, when processing precious metals such as gold crowns, the bottom member and the inside of the box can be cleaned easily and quickly. It is possible to remove the upper paper sheet and reliably collect all the precious metal processing waste that has fallen on the paper sheet, which can be used to recycle expensive resources. Furthermore, according to the present invention, if the workpiece is large, the top cover must be opened to take it in and out; however, if the workpiece is small, it can be taken in and out from the tool insertion hole without having to take it in and out from the top cover each time. It is possible and convenient. In addition, when machining a small workpiece, hold the small workpiece with the fingertips of your left hand and take it out of the box through the tool insertion hole. It is also possible to process workpieces. It is also possible to process the workpiece by holding the workpiece and the processing tool with both hands near the tool insertion hole outside the box. In these cases, even if the box made of highly transparent material or the top cover gets damaged, the workpiece and processing tools can be seen directly and the processing can be carried out because the processing is being done outside the box. It can be done easily and reliably. Machining of the workpiece outside of this box is performed near the tool insertion hole, and this is the area where the wind toward the exhaust hole is particularly fast, so machining chips, dust, etc. are exhausted without scattering. Of course, it is efficiently sucked into the holes. Also,
The present invention is not limited to processing dentures or denture bases, but can also be applied to processing other workpieces, such as deburring cast products.
