Professional Nose-convex Rockwell Hardness Tester Manufacturer
—Laizhou LaiHua Testing Instrument Factory
The convex nose Rockwell hardness tester is an indispensable precision inspection instrument for hardness testing of inner wall materials of industrial annular and tubular workpieces. Custom-designed for components including gear inner bores, bearing raceways, mold cavities and other parts, it addresses longstanding industrial drawbacks of conventional flat-type Rockwell hardness testers, such as unstable workpiece clamping and distorted measurement readings.
For quality inspection laboratories, component production lines, third-party testing organizations, heat treatment workshops, and high-end aerospace manufacturers, an extended nose Rockwell hardness tester with stable performance and precise readings serves as core equipment to control material properties and guarantee consistent product quality.
Laizhou LaiHua has devoted years to the R&D and manufacturing of hardness testing equipment, fully addressing common testing pain points across all industries. Aligned with international standards and technical specifications issued by metrology institutes, we independently develop high-compatibility, high-precision extended nose Rockwell hardness testers. We deliver one-stop complete hardness testing solutions for such equipment to manufacturers in diverse industries.
Product Features:
Coaxiality & Perpendicularity
The integrated optimized mechanical structure of the whole machine ensures the test force is applied vertically and accurately at the apex of the convex surface. It eliminates displacement during testing and guarantees high measurement precision.
Design for Special Workpieces
Adopting a forward protruding indenter design, the indenter can reach irregular inner positions directly. Apart from conventional workpiece measurement, it facilitates hardness inspection on inner areas of various components.
Manufactured in Compliance with Standards
Produced strictly in accordance with international standard ISO 6508-2:2015. The test force is controllable with high precision. The whole process including application and dwell of preliminary test force and major test force runs stably. The error of test force is strictly controlled within ±0.5%, complying with national hardness metrology specifications.
Intelligent Curved Surface Compensation
The instrument is equipped with a curvature correction program, which automatically offsets systematic errors caused by workpiece curvature without manual conversion.
