Abstract (en)
[origin: EP0683012A1] The machine has first and second swinging arms, mounting fixtures, pintles and clamping jaw assemblies. Each jaw assembly has an upper and lower jaw and a pintle which provides their rotatable connection. Each of the jaw assemblies has a mounting for holding the working tools for simultaneous machining of the material of the adjacent channels of the crank journal seats by rotation of the crank around the crankshaft's rotational axis. <IMAGE>
