铂金磨光设备

铂金可以用手磨光,或通过旋转工具进行磨光。 以下所示设备用于手工磨光。

This one features a highly polished stainless steel tip with a curved, smooth surface. For ease of use, it’s mounted in a wooden handle. This tool is useful for burnishing light scratches in platinum ring shanks.

可使用旋转式磨光设备对铂金进行磨光,设备安装在活动轴或微型马达带动的手持设备上。 这些工具运用广泛,十分好用。

This small L-shaped burnisher was fashioned from a used rotary tool. It is ideal for moving metal into depressions. It leaves an irregular finish on platinum that will need some abrasive finishing and light polishing.
