磨方法に関する。[Detailed Description of the Invention] This invention includes a workpiece, an abrasive material and, if necessary, water in a barrel tank.
The present invention relates to a polishing method in which high-speed planetary rotating barrel polishing and rotary barrel polishing are continuously performed while the compound remains charged.
従来高速遊星旋回バレル研磨は加工能率の高いことで多
用されているが、バレル槽内に装入される研磨材等によ
り加工された工作物の表面アラサには限界があつて一定
アラサに達するとそれ以上の向上は望めない。Conventional high-speed planetary rotating barrel polishing has been widely used due to its high processing efficiency, but there is a limit to the surface roughness of the processed workpiece due to the abrasive material charged into the barrel tank, and once a certain roughness is reached. I can't hope for any further improvement.
一方回転バレル研磨は加工能率は低いが加工された工作

回バレル研磨で粗仕上を行なつた後、内容物を回転バレ
ル槽へ入れ替えて回転バレル研磨を行なうようにしてい
るので内容物の入れ替えに時間がかかる上に多大の労力
を要する。On the other hand, rotating barrel polishing has a low processing efficiency, but is characterized by greatly improving the surface roughness of the processed workpiece. Therefore, if two processes of rough finishing and gloss finishing are required, perform the rough finishing with high-speed planetary rotating barrel polishing and replace the abrasive with a glossy one to achieve a glossy finish, or alternatively perform the rough finishing with high-speed planetary rotating barrel polishing. After aging, the contents are transferred to a rotating barrel tank and the rotating barrel polishing is performed, which takes time and requires a lot of effort.

程である。Furthermore, the use of a high-speed planetary rotating barrel polishing machine and a rotating barrel polishing machine improves the surface roughness, but has the drawbacks of requiring a large installation area and being expensive. However, according to this invention, the barrel tank charged with the workpiece, abrasive material, water and compound is rotated and orbited at high speed in a planetary manner, and after rough finishing the workpiece, the revolution of the barrel tank is stopped. Subsequently, the workpiece is given a glossy finish using the same abrasive material by rotating only on its own axis, so that high-speed planetary rotating barrel polishing and rotating barrel polishing can be performed continuously using the same abrasive material. Therefore, since the two steps of polishing can be performed in conjunction without replacing the contents (referred to as mass), the above-mentioned drawbacks of the conventional barrel polishing method have been completely solved and an ideal barrel polishing method has been successfully obtained. Note that the polishing in the above two steps is not limited to a rough finish to a glossy finish, and can also be performed, for example, from a glossy finish to a super glossy finish.In short, the second step further polishes the workpiece finished in the first step. This is a process of finely finishing.

磨材が使用できる。A predetermined amount of workpieces and abrasive materials are charged into the barrel tank 8 using the automatic supply device 26 and the hopper 25, water and compound are added if necessary, and a lid is attached to the barrel tank using the barrel tank lid opening/closing device 21. Seal tightly. When all the barrel tanks have been prepared, the motor 14 and the barrel rotation motor 22 are mainly started. The rotation speeds of both motors may be selected as appropriate, but normally the barrel tank rotation motor 22 is stopped and the ratio n/N between the revolution number N and the rotation number n of the barrel tank is set to -1. It is best to do so. In addition, the number of revolutions of the barrel tank in this case is determined by the revolution radius of the barrel tank being R (m
) 60 to 200/J per minute? Good results are obtained by selecting a rotation, optimally between 100 and 160/V/min. In this way, the workpiece is polished by rotating the barrel tank at high speed in a planetary manner so as to rotate and revolve around it. When the first step is completed, the main motor 14 is slightly moved so that the roller 20 of the fixed position stopping device 19 fits into the recess 18 of the turret 5, and the main motor 14 is stopped. When the revolution of the barrel tank 8 is thereby stopped, the rotation speed of the barrel tank rotation motor 22 is set to an arbitrary rotation speed. The rotation speed (rotation speed) of this barrel tank is the inscribed circle radius of the barrel tank r (m)
15 to 3V1 per minute? revolutions, optimally 18 per minute
~25/l? Selecting rotation gives good results.
In this way, the workpiece is polished by only rotating the barrel tank. When the second step is completed, the barrel tank rotation motor 22 is stopped, the lid is removed by the barrel tank lid opening/closing device 21, and the barrel tank 8 is rotated to discharge the mass onto the vibration sorter 13 and sort it. One cycle is completed. It will be more effective to use an abrasive for semi-finishing (manufactured by Shikishima Tipton Co., Ltd. with symbols AH, AX, AW, etc.) as the abrasive used in carrying out this invention, but various abrasives may be used depending on the purpose of polishing. can.

In addition, although the variable speed motor was used to change the revolution speed and rotation speed described above, a frequency converter (inverter) may also be used.
