Twin Spindle Turning Center

The “2 plus 4” principle has represented the most economical and efficient means of multi-spindle machining in manufacturing, according to Stama. The company has implemented this principle, with two spindles and four clamped workpieces, in hundreds of existing projects worldwide, resulting in reduced cost per part scenarios for its customers. However, the company has recently conducted discussions with its customers concerning better factory floor use and non-productive capacity.

The “2 plus 4” principle has represented the most economical and efficient means of multi-spindle machining in manufacturing, according to Stama. The company has implemented this principle, with two spindles and four clamped workpieces, in hundreds of existing projects worldwide, resulting in reduced cost per part scenarios for its customers. However, the company has recently conducted discussions with its customers concerning better factory floor use and non-productive capacity. Therefore, the company has developed the four-spindle Twin2 concept that’s now being introduced for multi-spindle machining applications.

 

While twin spindle machining needs to double the capacity of the tool magazine, the four-spindle solution requires a tool magazine to handle four times as many tools. The MC 531/Twin² is equipped with 56 tool places in the standard version, for example, with options for magazines with as many as 120 tools.

 

In four-spindle machining with short tool-to-part contact times, the load and unload sequences of the workpieces are key. In such cases, as long as the machine isn’t equipped with a quick automatic loading/unloading system, pendulum machining is advisable. This ensures parallel machining time while loading new workpieces. Time for loading and unloading can then be as long as the actual cycle time of the machine. This will also result in less time when the operator is interacting with the machine, thereby allowing the operator to run multiple stations in a work cell setup, while keeping a constant touch time protocol on each machine.
