A Surface Roughness Specimen Set typically includes a collection of standard
reference samples that represent different levels of surface roughness. This
specific set with 30 pieces provides a comprehensive range of roughness values
to help users visually and tactilely compare and evaluate the surface finish of
materials. These specimen sets are commonly used in machining, manufacturing,
and quality control to ensure that the surface finish meets specific industry
standards and requirements.

• For checking, identifying and specifying the roughness by symbol
• Accuracy: -17% ~ +12%

Benefits:

• Quick and Convenient: Provides an immediate visual and
  tactile reference for comparing surface finishes, making it easy to evaluate
  roughness without needing expensive equipment.
• Versatile and Comprehensive: With 30 specimens, users
  can reference a wide range of roughness values and machining types, catering
  to diverse industry requirements.
• Cost-Effective: Allows for surface finish assessment
  without the need for sophisticated instruments, which can be expensive and
  require specialized training to operate.

A surface roughness specimen set with 30 pieces is a practical tool for
anyone involved in quality assurance, machining, or product development who
needs a reliable and accessible way to assess and verify surface finishes
according to industry standards.
