Manufacturing of the tangential radial screws

• Reduction of dynamic loads on the power transmission of the gearboxes of the shearer cutting units. Increasing the service life of the screws before overhaul repair.

• High daily productivity achieved by increasing the loading capacity of the screws.

• High wear resistance of the cutting tool (up to 20 times higher than the Ukrainian and Russian analogs).

• Ability to work in extremely abrasive conditions (more than 130 MPa).

• Low production costs.

• Reducing the current load on the motor of the operating member up to 20%.

• Various screw designs: cylindrical; with a conical cutting disc; universal.
