A unique benefit of the twin table design is that when one table is in the forward position and one is completely back, you can place a part on each table that is the same size as the table and still independently machine completely around both parts. You can also perform pendulum processing or add a second spindle for dual process capability.

With the twin table configuration, you can load Table 1 safely while performing machining operations on Table 2. Then, while the machine switches to processing material on the newly loaded Table 1, you safely remove parts from Table 2 and reload the table. This technique is known as Pendulum Processing, and it keeps your production continuously flowing.

By adding a second spindle to the twin table configuration, you gain flexibility in your production, a value equal to buying an additional machine without the expense or taking up valuable floor space. You can cut twice as many parts in the same time period. 

• Use one spindle to machine one process on Table 1, while the other spindle machines an entirely different process on Table 2.
• Use both spindles on an alternating basis to perform different operations on a single workpiece. 
• Use both spindles on a fixed center distance to produce identical parts at the same time on the same table (while still pendulum processing) or different tables.
• Use both spindles on a frequently adjusting or varying center distance while working on a single process.
• Park one spindle and electronically lock the tables together, giving full table access to the other spindle for machining large or oversized parts.

Adding additional spindles to your machine gives you the versatility equivalent to having multiple machines. All spindles can be cutting identical parts simultaneously to keep production flowing, or consider, for example, equipping one or two spindles with 4th axis capability aggregates (specialized tooling) and when the initial 3-axis processes are finished, park those spindles, and send in the 4-axis spindle(s) to machine the sides of the material without losing the time required for refixturing. The E-Series supports up to 8 spindles.
