- barrel polishing is performed by collision and contact between a workpiece and a medium in a barrel polishing tank. If the intersecting part 01a, the boundary part 01b, and the vertex 01c form an acute angle, when the work comes into contact with the medium, a strike mark may be formed on the surface of the work or may be damaged.

Two types of media having the shape described in the embodiment were formed by molding a mixture in which abrasive grains were dispersed in a thermosetting resin having a Vickers hardness of 25 HV so as to be 60% by mass of the total (diameter of the bottom surface 13a).

前記メディアとワークの比率を、容積比(メディア全体の容積/ワーク全体の容積)で5.0となるようにし、これを断面が六角形である4つのバレル研磨槽のそれぞれに、前記メディアを、前記バレル研磨槽の容積の1/2となるように投入した。その後、該バレル研磨槽を前記遠心バレル研磨装置に載置し、該バレル研磨槽を自転速度200rpm、公転速度200rpmにて0.5時間運転した。研磨加工終了後、バレル研磨槽を遠心バレル研磨装置より取り外し、該バレル研磨槽よりワークを取り出した後、新たに同量のワークをバレル研磨槽に投入した後、同様に研磨加工を行った。これらの操作を繰り返して、70回の研磨加工を行い、1回目の研磨と70回目の研磨における「メディアの形状」「ワークの打撃痕」「ワークの仕上げ」「研磨力」について評価を行った。各評価は下記の通りとした。
メディアの形状:目視にて、初期の形状とほぼ同一(大きさは異なっていてもよい)の場合は○、若干の変化が認められる場合は△、初期の形状と大きく異なっていた場合は×とした。
ワークの打撃痕 :目視で打撃痕が認められない場合は○、打撃痕が認められる場合は×とした。
ワークの仕上げ:目視にて、ワークの前記L字形状部の隅角部の皮膜が除去されている場合は○、該隅角部の皮膜が除去されていない場合は×とした。
研磨力 :研磨加工前と研磨加工後の重量変化を測定した。 Polishing was performed for the purpose of removing a film (paint film) of a black-coated workpiece (an angle steel having a bottom surface of 10 × 10, a thickness of 2 mm, an R surface at an intersection of 1.0 mm, and a length of 10 mm).
The volume ratio (volume of the entire medium / volume of the entire work) is set to 5.0 so that the ratio of the medium and the work is set to 4 barrel polishing tanks each having a hexagonal cross section. The barrel polishing tank was charged to ½ the volume. Thereafter, the barrel polishing tank was placed on the centrifugal barrel polishing apparatus, and the barrel polishing tank was operated for 0.5 hours at a rotation speed of 200 rpm and a revolution speed of 200 rpm. After completion of the polishing process, the barrel polishing tank was removed from the centrifugal barrel polishing apparatus, the workpiece was taken out from the barrel polishing tank, and the same amount of work was put into the barrel polishing tank, followed by polishing similarly. By repeating these operations, the polishing process was performed 70 times, and “media shape”, “work impact mark”, “work finish”, and “polishing power” in the first polishing and the 70th polishing were evaluated. . Each evaluation was as follows.
Media shape: Visually the same as the initial shape ○ (when the size may be different), △ if slight change is observed, △ if significantly different from the initial shape It was.
Blow mark of workpiece: “B” when no hit mark is visually observed, and “X” when a hit mark is observed.
Finishing of work: When the film of the corner portion of the L-shaped part of the work was removed visually, it was evaluated as ◯, and when the film of the corner portion was not removed, it was marked as x.
Polishing power: The change in weight before and after polishing was measured.
メディアの形状:70回の研磨加工後のメディアの形状は、実施例1、実施例2、比較例1は初期に比べ小さくなっているものの、形状に大きな変化は認められなかった、一方、比較例2は球形、比較例3は楕円体にそれぞれ近づいていた。比較例4および5は、前記径Xと前記高さYとの比(Y/X)がそれぞれ約0.5、約1.4まで変化していた。
ワークの打撃痕:何れのメディアによるバレル研磨においても、ワークへの打撃痕は確認できなかった。
ワークの仕上げ:実施例1、2は1回目および70回目のバレル研磨においても、ワークの隅角部の加工が完了していた。比較例1はいずれのバレル研磨においてもワークの隅角部の加工が完了しておらず、比較例2~5はいずれも1回目のバレル研磨ではワークの隅角部の加工が完了していたが、70回目の研磨ではワークの隅角部の加工が完了しておらず、メディアが偏摩耗したことでワークの隅角部との接触が不十分となったことがわかる。
研磨力 :研磨により形状に変化が生じるメディア(比較例2~5)によるバレル研磨では、いずれも1回目の研磨後のワークに比べ70回目の研磨後のワークとの表面粗さは大幅に大きくなっていることから、偏摩耗による形状の変化によって研磨力が減少していることが分かる。また、比較例1のメディアにより研磨されたワークは、1回目と70回目で大きな差がないものの、実施例1および実施例2のワークにより研磨されたワークの表面粗さより大きく、比較例1のメディアは十分な研磨力を有していないことがわかる。一方、実施例1および実施例2のメディアにより研磨されたワークの表面粗さは、研磨前より大幅に小さくなっており、かつ1回目の研磨後と70回目の研磨後のワークの表面粗さの差が小さいことから、長時間にわたって良好な研磨力を持続していることが分かる。特に、実施例1のメディアは実施例2によるメディアによる研磨より、1回目の研磨後と70回目の研磨後の差が小さいことから、より好ましいことがわかる。 The evaluation results after barrel polishing are shown below. Thus, it can be seen that the media according to the present invention is free from uneven wear of the media and a decrease in the polishing amount with the lapse of the polishing time, and can perform barrel polishing well even at the corners of the workpiece.
Media shape: The shape of the media after 70 polishing operations was smaller in Example 1, Example 2 and Comparative Example 1 than in the initial state, but no significant change was observed in the shape. Example 2 was close to a sphere, and Comparative Example 3 was close to an ellipsoid. In Comparative Examples 4 and 5, the ratio of the diameter X to the height Y (Y / X) was changed to about 0.5 and about 1.4, respectively.
Striking marks on the workpiece: Neither of the media was able to confirm the scratching marks on the workpiece in barrel polishing with any media.
Finishing of workpiece: In Examples 1 and 2, the machining of the corner portion of the workpiece was completed even in the first and 70th barrel polishing. In Comparative Example 1, processing of the corner portion of the workpiece was not completed in any barrel polishing, and in Comparative Examples 2 to 5, processing of the corner portion of the workpiece was completed in the first barrel polishing. However, it is understood that the machining of the corner portion of the workpiece is not completed in the 70th polishing, and the contact with the corner portion of the workpiece becomes insufficient due to the uneven wear of the media.
Polishing power: In barrel polishing with media (Comparative Examples 2 to 5) whose shape changes due to polishing, the surface roughness of the workpiece after the 70th polishing is significantly larger than that after the first polishing. Thus, it can be seen that the polishing force is reduced by the change in shape due to uneven wear. Moreover, although the workpiece | work grind | polished with the medium of the comparative example 1 does not have a big difference by the 1st time and the 70th time, it is larger than the surface roughness of the workpiece | work grind | polished by the workpiece | work of Example 1 and Example 2, It can be seen that the media does not have sufficient polishing power. On the other hand, the surface roughness of the workpiece polished by the media of Example 1 and Example 2 is significantly smaller than that before polishing, and the surface roughness of the workpiece after the first polishing and after the 70th polishing. From this, it can be seen that good polishing power is maintained for a long time. In particular, it can be seen that the media of Example 1 is more preferable than the media with Example 2 because the difference between the first polishing and the 70th polishing is smaller.
The barrel polishing media of the present invention can be suitably used for both dry barrel polishing and wet barrel polishing. Moreover, it can be suitably used not only for centrifugal barrel polishing described in the embodiments but also for polishing by a known barrel polishing apparatus such as a vibration barrel polishing apparatus, a fluidized barrel polishing apparatus, and a rotary barrel polishing apparatus.
