Fully Automatic Rotary Surface Grinder
Chevalier has added the FRG-400/600 rotary surface grinder to our grinder series. This series features several excellent designs, ensuring a smooth and stable ribbed high-rigidity column structure, capable of handling heavy-load grinding with a fully enclosed hydrostatic rotary table.
Ample interior grinding space and a double door design contribute to ease of access for workpiece loading and unloading. The drainage system easily removes swarf for cleaning. The machine is fully enclosed with a sealed, waterproof metal guard.
This series of grinders meets the high-efficiency productivity requirements and the demand for creating smart factories in industries such as aerospace, automotive, energy, medical, and semiconductor.
