Stands 30 Specimens Roughness Stand Comparator Gauge Block Set, Ra0.05-12.5mm Microfinish Comparator, Manufacturing Teaching

Specifications:The exterior roughness comparator is used to check the smoothness of mechanical workpieces by comparison, while the inspection or microscope is used to compare and test the degree of exterior roughness.Features:RUG-100: notebook sample block (turning, end milling, flat milling, exterior grinding, external grinding, polishing).The notebook sample block contains standards for the six most important processing methods among the popular "AA" values. All 30 samples were calibrated with uAA (arithmetic mean) and metric equivalent um Ra.Sample exterior roughness comparator 30 pieces of composite bag fixing gauges.3 Flat grinding: 2,4,8; 7/8 "x 3/8" each; Each type of exterior finish is a true and consistent reproduction, with a true idea of the feel, appearance and texture of d parts.Compare conveniently and quickly; Comply with S.A.E and specifications.Overall wallet size (fully enclosed) L x W x H (inches): 6 x 3 x 3/8 * estimated *; Unit weight: 14 ounces * estimate only*.Package Including:A set of 30 sample pieces

• Stable and : These kits are made of stable and made of 45 super carbon steel, which is corrosion-resistant, not easy to deform and . It has a protective oil film to effectively prevent rust. You can rest assured of long-term and repeated use to ensure accuracy and reliability.
• Various Processing Methods: It can measure the roughness of six processing methods (horizontal milling, vertical milling, turning, plain grinding, flat lapping, external grinding). Able to perform a variety of functions such as measurement of different types of s, inspection of various textures, etc.
• The model number of the set is clearly marked, and the sample blocks are arranged neatly and correspond one to one, it easy to compare, observe and distinguish. Whether you are a professional engineer or a student, you can easily operate and compare to meet your needs.
• High-precision Measurement: roughness stand comparator come with 30 samples of different roughness levels, providing you with a wide range of choices to easily distinguish and compare different qualities to ensure that the product meets the highest standards.
• Wide Range of Applications: Not only suitable for roughness measurement, quality control and instrument calibration, it is also a teaching aid for mechanical majors in colleges and universities, meeting various application needs in different industries and fields.
