Balance Reamer

Background

• In deep hole drilling, the tool protrusion is longer, resulting in a large rotational balance (misalignment of the cenere of gravity), and the centrifugal force during rotation causes the tool to behave, resulting in unstable machining accuracy.
  In addition, insufficient coolant supply to the guide section caused welding and scratches on the workpiece surface.

Point for Development

• The ‘Balance Reamer’ uses a special flute shape with balanced rotation to suppress run-out during rotation and an optimized guide pad arrangement to stabilize the machining accuracy of deep hole drilling.
  Furthermore, by supplying coolant to the entire guide, the lubricity is improved, which prevents welding to the guide and scratches on the workpiece surface.
