KCM 150 N
 

The KCM 150 N single-column wheel boring machine is designed for machining of railway wheels.

The machine tool can perform the following turning operations controlled by technological program:

-Wheel hub fine boring;

-Hub facing;

-Chamfering;

With a special equipment, it is possible to extend the machine capabilities to the following operations:

-Wheel hub rough boring with 1-mm allowance on each side;

-Machining of solid wheels;

-Machining of wheel centres;

-Boring of tyres;

-Drilling of assist oil injection holes in wheel hubs;

For wheel production purposes a double railhead version of increased productivity can be provided.
