Product Introduction

 

Overview:
The BR-GC204 "Tolerance Fit Precision Testing" Combination Training Platform is a set of practical part precision testing combination training products carefully designed by our company's teaching and research personnel based on the teaching requirements of the "Tolerance Fit and Technical Measurement" course, as well as the actual requirements of modern enterprises for precision testing engineering and technical personnel. It consists of three major parts: Part Size Accuracy Testing, Shape and Position Accuracy Testing, and Surface Roughness Comparison Testing. Its purpose is to deepen students' understanding of the basic concepts of error and tolerance, master the skills of error measurement methods, and lay a solid foundation for the learning of the course "Tolerance Fit and Technical Measurement" and the application of tolerance fit knowledge in subsequent courses through the detection of part size errors, shape and position errors, and surface roughness.
1、 Three major functions
Error measurement training;
Training on qualified parts judgment;
Error analysis training.
2、 Five major characteristics
1. Project implementation: using real parts as testing objects and actual measuring tools as testing methods;
2. Functional systematization: a training mode that integrates error measurement, qualified part judgment, and error analysis;
3. Popularization of students: small combination desktop training devices, two to three people in groups, allowing as many students as possible to have sufficient training opportunities;
4. Teaching standardization: The accompanying standard drawings and guidebooks make teaching and learning very convenient, and the teaching effect is significant;
5. Management convenience: Testing parts, measuring tools, standard drawings, and manuals are all placed in the combination platform training, making management very convenient.
