A plurality of pot support members each for detachably supporting the pot are connected, and an endless track is generated for guiding the pot support members driven by sprocket members. Each of the pot support members is supported with a pair of pins so that the pot support members are connected into a chain-like formation. The pitch between the pair of pins for supporting the pot support member is made substantially equal to the pitch between the pins of the adjacent pot support members so as to allow the resultant track to meander both inward and outward.

The chain magazine for holding tools (5) for machine tools includes a continuous chain (1) which has chain links (2) each with at least one tool holder (2a, 2b) and with which at least one sprocket (6, 7) meshes and a guide device (9-12) which has a guide element (12) that can be moved back and forth between a first and a second position, by means of which a tool holder (2a, 2b) of a chain link (2) can be turned in and turned out.

The invention relates to a machine comprising a first machining module (1) configured to simultaneously machine at least two crankshafts, a second machining module (2) configured to simultaneously machine at least two crankshafts, and a support structure (3) with at least four crankshaft fixing positions (31, 32, 33, 34) for the machining of such crankshafts. The support structure (3) is located between the machining modules. The fixing positions (31, 32, 33, 34) are arranged in two columns (35, 36) of fixing positions, each of which comprises at least two of the fixing positions (31, 32; 33, 34) located at a different height, and the support structure (3) is rotatably arranged, such that it can perform a rotation of at least 180 degrees.

A tooling assembly for a machine having an automatic tool changing system includes a tool body disposed about a rotational axis and defining an internal passage operable to flow a fluid therein. The internal passage includes an inlet, stem channel, first and second curved channels, and first and second transition portions. The inlet is configured to receive the fluid from the machine. First and second outlets are open through an exterior of the tool body. The stem channel is in fluid communication with the inlet and ends at a beginning of the first and second transition portions. The first curved channel extends from the first transition portion to the first outlet. The second curved channel extends from the second transition portion to the second outlet.
