The Habegger guide bush with three positions called hereafter TP bush is a non-revolving bush fitted with tungsten carbide rollers the adjustment of which is done by a pneumatic cylinder.
Its principle is relatively simple: The conventional guiding elements of Habegger bushes with rollers do not change. The inside components are identical with those of our present guide bushes, excepted the nut at the back. That nut, used for manual adjustment, has been replaced by a pneumatic cylinder permitting to adjust the bush at any time.
The material bar is guided by tungsten carbide rollers, driven by the rotation of the bar. That is the principle of a needle bearing, the inside cage of which would be the material bar (direct contact) and it results in an optimal material guiding.
The guide bush can only be used for bars of the diameter which corresponds to the size indicated on the cap.
Non-revolving bush fitted with tungsten carbide rollers. Direct Contact with the machined material bar. The adjustment is done by a pneumatic cylinder
3 positions: working – clamping – open
Before machining each workpiece, the guide bush gets adjusted to the exact tolerance (ma. h11) of the material bar, there where the workpiece will be clamped
Assembly is possible with guide bush holders of our production on most of the CNC machines
