Introduction
Our company delivers abrasive materials of Australian origin - garnet GMA. Thanks to its unique hardness and solidity of grains it secures the highest productivity and perfect quality of cutting. Highly precise sorting secures 100% effectiveness without any dust and excessive grains and this way permanently optimal cutting conditions and stable supply of abrasive without choking of abrasive nozzles. This way the highest effectiveness of production and lowest manufacturing costs during the whole time of cutting.
Abrasive material is suitable for all cutting applications including:
- carbon steel
- copper
- granite
- aluminum
- rubber
- glass
- corrosion-resistant steel
- marble
- wood and other materials
