CHEVALIER - FSG-H818CNC

High Efficiency Precision 2-Axis CNC Profile Grinder

Features

The FSG-H818CNC (2-Axis CNC) & FSG-B818CNC (3-Axis CNC) grinding machines are high precision, high efficiency multi-purpose CNC profile grinders. These machines are designed to meet current and future grinding requirements such as intricate profiles and mold components. It is well suited for aircraft, automobile, electronic, medical, machine tool and defense industry parts.

  • The FSG-H818CNC with two mode air cooled hydraulic table drive can be set to low speed for creepfeed grinding or high speed for conventional grinding adding to the machine’s versatility.
  • The FSG-B818CNC table is driven by a precision ballscrew and an AC servo motor to provide precise positioning and achieve optimum speeds needed for creepfeed grinding.
  • Column and wheel head traverse on precision roller bearings and hardened and ground guideways that are pre-loaded and driven by a precision ballscrew, to provide excellent rigidity and precise positioning.
  • Integrated machine structure is well suited for heavy duty grinding. Creepfeed grinding can be utilized to grind deep slots with a single pass through high hardness materials.
  • A Fanuc CNC control provides full automation through programming in order to grind multi-shaped workpieces and complete the entire grinding process. This includes rapid approaching, rough grinding, wheel dressing with auto compensation, and fine grinding in one fully automatic cycle.
  • A forced flood coolant, accompanied by a totally enclosed splash guard efficiently cools the workpiece efficiently and helps prevent thermal damage and workpiece distortion.
  • Crossfeed and elevating axes are positioned by precision ballscrews and an AC servo motor for providing superior accuracy and excellent longevity.
