DRILLING HEAD HAPONIC 450/275 serves as a source of torque for rotation drilling The boring head /drilling head is equipped with two hydraulic motors whose connection enables to change the scope of revolutions easily. The revolutions in the given scope are controlled by means of regulating elements which are part of the hydraulic system of the bohring machine.
The speed is changed by means of a four-way valve which is part of the boring head. Various boring pins and flushing heads may be connected to the main shaft. The maximum torque and revolutions depend on hydraulic motors used – see the table.
Various types of hydraulic motors can be in the driling head according to the customers requirements. The main shift is movable in the axial direction so that the connection of the boring bars is easy.
