ABSTRACT:
An improved machining device is disclosed which is particularly well suited for machining of a wide variety of materials and in particular elastomeric materials such as for example synthetic rubber employed in manufacture of motor vehicle tires. The machining device comprises a rotatable wheel having secured around the periphery in spaced relationship a plurality of replaceable cutting inserts each of which incorporates piercing corner portions having an acute included angle followed by a sharp linear edge portion operable to produce a clean severing action which results in a finely textured machined surface. Each of the inserts also incorporates a securing arrangement which allows the cutter inserts to be quickly and easily secured to the wheel and also accurately locates the cutting edges thereof along a common circle concentric with the axis of rotation of the wheel. Various arrangements are also disclosed for preventing rotational movement of the cutter insert during use thereof.
