Fermat’s BHCR cylindrical grinding machine is designed for external and internal grinding operations on complex workpieces in both serial and small-lot production. The program-controlled rotation of the grinding head along the Y axis enables sequential plunge or longitudinal grinding with a moving table, and plunge grinding with a stationary or oscillating table. Equippable with as many as three grinding wheels, the feature also improves the ability to grind with more tools in one clamping arrangement, eliminating time delays caused by changing grinding wheels for internal grinding procedures, manually tilting the head or rotating and reclamping the workpiece.
Interpolation of perpendicular axes using the Z-axis table feed and the X-axis grinding wheel feed enables a range of grinding operations, with a dressed grinding wheel also available for external and internal grinding. Workpieces can be clamped between centers for precise cylindrical or conical grinding, or held in place with an optional chuck. Additionally, the end surface of the workpiece can be ground by the side of the wheel.
