BT/BTA: working parameters

– SYSTEM FLEXIBILITY AND MACHINING TIME

The chance to use inserts with several sizes and shapes, makes it possible to machine internal profiles which could otherwise obtained only at high costs.

It’s important to point out that, cutting speed and increment depend on the kind of material to machine. Down below there is an example of a keyseat machining operation (pic.6) indicating the machining time and the life of the insert.

When a high quantity production is not required, BT/BTA system is suitable to machine internal splines, with several different features (pic.7).

Down below some suggestions about machining parameters with regards to the material to machine

V =cutting speed (mt/min)

I = Increment (mm)
