Product Q&A

Q:What is a Surface Roughness Comparator used for?

A Surface Roughness Comparator is used to compare the surface finish of machined parts by visual and tactile inspection. It helps operators quickly estimate surface roughness without using electronic measuring instruments.

Q:What surface roughness range does this comparator cover?

This comparator covers a roughness range from Ra 0.05 um to Ra 12.5 um, making it suitable for most common machining and finishing applications.

Q:Which machining processes are included in this comparator set?

The set includes reference samples for turning, vertical milling, horizontal milling, plain grinding, external grinding, and flat lapping, covering a wide range of metalworking processes.

Q:Is this comparator suitable for all metal materials?

Yes. It can be used to evaluate the surface finish of various machined metal parts, including steel, stainless steel, aluminum, cast iron, copper, and other engineering materials.

Q:Can this comparator replace a surface roughness tester?

No. It is designed for rapid visual and tactile comparison. For precise numerical measurements and inspection reports, a digital surface roughness tester is recommended.
