Koyo’s buffs complying with various needs
It is necessary for you to choose a right buff fitting to work.

Why is it necessary for you to choose a right buff fitting to work?

Modern finishing influences not only a product’s appearance, but also its functional value and price. Every finishing operation is a step toward producing a salable item … and profits. The increasing complexity of contours to be finished plus constant advances in buff design and automatic machinery have changed buffing from an art to a science. Modern high-speed buffs are precision production tools, which are used in a wide range of applications. The right buff can increase production rates, reduce per unit cost, and produce a better finish.
The characteristics of bias buffs

1. As the Koyo’s bias buffs made of long bias cloth cut by 45 degree, tip of cotton thread on circumference cuts and no run of thread. Besides, the condition of run of thread on circumference is quite same. As a consequence, long life can be expected with constant wear comparing with the buff used conventional drill (cloth). Therefore, it is especially less number of adjustments for automatic machine and it is not only sanitary but also prevent from wear of machines.
2. Koyo's bias buff is formed with multiple layered pleats. By changing the length of its cloth, the hardness of buff can be adjusted. Also the pleats hold more polishing compounds, and leave less buff scratches.
3. As the Koyo’s buffs possess a center clip for better ventilation, the working piece is fully cooled and decreased a burning condition. By the above mentioned various characteristics, the Koyo’s buffs can polish with a low polishing pressure with a high speed revolution so that a reduction in polishing time, evenness of the polishing surface, so called working efficiency and stability of quality can be obtained effectively.
< Maximum Revolution Speed for Buffs >
Please use buffs within the range of Max. revolution speed which is indicated in seal of each buff because of the difference of rotational strength by the structure of buffs and kinds.
