What does CPC think about ultrasonic finishing devices? If you are finishing a large surface, hand processing or using rotary tools is sufficient. Ultrasonic finishing devices are intended for areas that are difficult to process by hand (such as rib polishing and shaping of C surfaces), for situations where you want to finish quickly without losing micron-level shapes, or for fine processing such as slight shape or dimensional corrections. The ultrasonic finishing device, Serap(R), can be used for fine processing that was not possible with conventional methods. For more details, please contact us or refer to the catalog.

The grinder is strong, resistant to breakage, and has a soft touch, making it suitable for use with power tools and similar equipment. Moreover, its special structure ensures that it is less likely to break even at high rotation speeds, providing peace of mind.
