1、 Purpose and Characteristics

TM typeStone wear-resistant machineThe testing machine (hereinafter referred to as the testing machine) is mainly used to test the wear resistance or wear resistance of natural granite, marble, and other building decoration materials (such as artificial stone, microcrystalline glass, etc.).

stem or root of plantsStone wear-resistant machineManufactured according to Q/JY046-2006 "TM type stone wear resistance testing machine", it meets the requirements for test performance in Appendix A of the national standard GB/T19766-2005 "Natural Marble Building Panels". Strictly implement national product standards and testing method standards. This testing machine has the characteristics of beautiful appearance, small footprint, low noise, and multiple working heads (sample fixtures).

The wear-resistant medium used by the testing machine must comply with GB/T19766-2005According to relevant regulations in China, the presence of other impurities and chemical substances that are harmful to wear resistance testing is not allowed.
