Turning the reduction gear into an inverter

Turning a non-stage gear of the horizontal boring & milling machine (BT-8B) into an inverter.

• A conventional non-stage gear disappears.
• It is maintenance free.
• Its maneuverability is outstanding.

Phenomena that affect quality, precision and efficiency

Repairing the main electric motor (Toshiba 7.5 kW motor) is now difficult.
With a simple mechanism, there is no wear and tear, and no damaged parts.
It enables quiet operation with no mechanical noise.

Transmission mechanism that mechanically controls rapid traverse and feed speed

The AC inverter control controls feeding and only a single motor controls rapid traverse.

Feed speed is controlled by a small knob, eliminating heavy steering operation.

The volume control attached to the pendant enables quick operation.
