This machine is suitable for cutting the samples of various metal and non-metallic materials to observe the metallographic and lithofacies organization.




The new model HRD-150 electric Rockwell Hardness Tester is controlled by a motor for the loading, holding, and unloading of test force, with the option to select a hold time. It offers convenient, rapid operation without human error, and demonstrates high sensitivity and stability.


This mill throwing machine is a double disc machine, which can be operated by two people at the same time, suitable for pre-grinding, grinding and polishing operation of metallographic samples.


This grinding machine is suitable for pre-grinding, grinding and polishing of metallographic specimens. It is an essential device for users to make metallographic samples. This machine has a cooling device to cool the specimen during pregrinding to prevent damage to the specimen from overheating. The left plate of the machine is grinding plate, the right disc is throwing disc, can be two people at the same time, easy to use, stable and reliable.


This machine is used for grinding before throwing, for small, not easy to hold or irregular metallographic, rock phase sample inlay. After the inlay, it is easy to grind the sample. It is also beneficial to view the material organization under a gold microscope; test the hardness on the hardness meter.
