Crankshaft milling machine

A crankshaft milling machine comprising:

• a bed;
• a pair of rails fixedly secured to said bed;
• a column fixedly secured to said bed;
• a spindle head fixedly mounted on said column;
• chuck means mounted for rotation on one end of said spindle head, said chuck means being adapted to clamp the crankshaft to be milled;
• first motor means for imparting rotational movement to said chuck means;
• tool guide means slidably mounted on said rails, said tool guide means having an inverted U-shaped cross-section;
• tool support means movably mounted within said tool guide means, said tool support means being reciprocably movable in a vertical direction;
• second motor means for causing a reciprocating vertical movement of said tool support means;
• internal tooth cutter means rotatably supported by said tool support means, said internal tooth cutter means having interchangable cutter teeth mounted thereon;
• work rest means mounted on said tool support means for supporting the crankshaft to be milled;
• third motor means for rotating said internal tooth cutter means;
• and
• control means for controlling the relative movement of said chuck means and said tool support means such that the rotation of said chuck means is in synchronism with the reciprocating vertical movement of said tool support means.
