HS-215/225 Grinding System

The Huffman HS-215 and HS-225 Series Multi-Axis Superabrasive Grinding Systems provide increased productivity, superior precision and reliability for a wide variety of applications including flight and industrial gas turbine components (vanes, vane rings, nozzles, blades and shrouds). With an extended axis travel and up to 50 HP (37 Kw), the HS-215 and HS-225 are designed to accommodate larger parts and achieve high material removal rates.
