CNC indexing head can provide a lot of convenience for some multi-sided products, it can process the workpiece at multiple angles at one time, so it can obviously reduce the process of processing
However, when the workpiece itself (especially when machining the side of the workpiece) is relatively high, or the fixture height is relatively high, there may be interference between the tool and fixture when changing the tool, which may cause damage to the tool or even the tool changing system, to prevent this problem, we should pay attention to the following points
Placement of workpieces and fixtures on the table
Since the disc type tool changer is usually installed on the upper left side of the machine, the tool change will also take place on the left side of the spindle. When changing tools, a section of space under the tool arm will be temporarily used, so workpieces and fixtures should not be present here.
The table can be moved left and right, if the mounting position of workpiece and fixture is chosen on the left side of the table, then no matter how the table is moved, the workpiece and fixture will be on the left side of the spindle, which may not be a problem when the height of the workpiece and fixture is low, but once the workpiece and fixture conflict with the tool change action due to the height, then the workpiece and fixture will have to be removed and re-tuned.
Therefore, it is a good choice to use the right side of the table space as a priority.
Selection of tool change point
Due to the condition, the tool change action has to be done at a specific point, and this point can be preferred to the upper left corner of the table.
Consistency of the tool change point
We have mounted the workpiece on the right side of the table and the safe tool change point has been set in the program, however, when the operator is resharpening or changing the tool, it is likely to forget about the tool change point and cause damage to the workpiece or tool.
