Dynasil Fused Silica Expands Edge Grinding Capability


Finally, the long anticipated EcoTech GM-12 cylindrical grinder arrived at Dynasil Fused Silica (DFS).  The tried and proven method of edge grinding fused silica using the EcoTech GM-8 had served DFS well. However, to better serve the increasing demand from its customers for large-format synthetic fused silica edge grinding, DFS invested in an EcoTech GM-12 cylindrical grinder to create finished diameters of fused silica parts up to 457 mm, and hold tolerance to 0.05mm.

The new EcoTech GM-12 grinder enables DFS to create finished diameters within 0.05mm for fused silica larger than 8 inches. This was a year long collaboration with the OEM which resulted in modifying what is normally a 12-inch diameter maximum rated machine to expand its reach up to 18 inches.

Dynasil Fused Silica is excited to have this new piece of equipment and capability in-house. With two EcoTech cylindrical grinders, along with industry-leading and expert operators, the EcoTech GM-8 and GM-12 grinders will work in tandem to increase both capability and output at DFS.
