Series CNC Machining Using Turning Automatics
Turning automatics are machines designed for CNC series machining from bar stock, whose integral device enabling automatic operation is the bar feeder. This combination allows for precise machining of components with minimal operator involvement. Turning automatics can be classified according to the number of spindles:
- single-spindle
- or multi-spindle.
Single-spindle automatics
Single-spindle automatics come in two variants:
- automatics with turret heads
- and sliding-head automatics.
In the case of single-spindle automatics with turret heads, the goal is machining on a short section, where the workpiece bar, extended through the full machining length, rotates on its axis, and the tool mounted in the turret head cuts the material. Modern turning automatics are equipped with several heads working simultaneously. When operating sliding-head single-spindle automatics, the workpiece bar simultaneously performs rotational and longitudinal movement. This allows cutting the material to the desired shape and dimension. In both solutions, CNC series machining can be performed successfully.
Multi-spindle automatics
Multi-spindle automatics are intended for mass production. These machines use multiple spindles working in parallel, mounted on a shared rotating support – the so-called indexing drum – performing various operations simultaneously. Such equipment is particularly valued in the automotive industry, where CNC series machining guarantees product repeatability.
