The sliding headstock automatic lathe is used for the production of long pieces

The difference between an automatic lathe with a sliding headstock and an automatic lathe with a fixed headstock is determined by the workpiece, cutting speed and the feed. Automatic turning is conducted over the range of 2.5 times the diameter of the workpiece, after which sliding headstock automatic lathes work very efficiently.
  • Automatic turning requires rigid and working conditions that are free from backlash
  • Processes small and long workpieces
  • Mainly used in medicine and precision engineering

For automatic turning, working conditions that are particularly rigid and free from backlash are required. This allows a for a guide bush, whereas chucks are usually implemented for automatic lathes with fixed headstocks. An sliding headstock automatic lathe is used for the processing for small and long workpieces. The material feed is conducted using the main spindle. This allows for processing to be undertaken in close proximity to the guide bush, and thereby ensuring working conditions that are free from backlash. This type of processing guarantees high precision, even with very long workpieces. During the automatic turning process, material is first pulled in using a guide bush and the spindle stock. Then a collet chuck secures the material in place. A counter spindle is used to take up the material after it has been cut.

The rotating guide bush runs in a synchronised fashion to the main spindle. Cutting tools are generally positioned with a space of a millimetre away from the guide bush. The advantage of an sliding headstock automatic lathe is clear. Next to the high precision levels, there are hardly any problems with vibration or chatter marks. Thereby, the spindle bearings have a really long lifespan. A large variety of pieces can be produced using an sliding headstock automatic lathe. There is a really important requirement for material that will be processed using this machine: a high surface quality for used, centreless material. Without this quality, it is not possible to use the sliding headstock automatic lathe. Sliding headstock automatic lathes are equipped with various tools, depending on their configuration. They usually contain unloading systems for long pieces, a reinforced counter spindle, chip conveyor, a tool to monitor tools and signal if they are broken and even y-axes for milling. Modern CNC-control systems can be used for these machines and allows the machine to quickly switch to the required production tasks.

Areas of application and examples of sliding headstock automatic lathes

Automatic turning is used in many industrial sectors. This includes medical technology, machine construction and all other precision engineering sectors. CNC-controlled sliding headstock automatic lathes make it possible for necessary pieces for, for example, the medical industry to be produced with the highest level of precision. Processing can be undertaken with up to three tools simultaneously and this reduces the processing time. When using machines of the highest quality, it is possible to undertake the complete manufacturing process with up to 15 CNC-axes and more than 30 tools. These high-performance machines can be configured in accordance with production requirements. Workpieces, which are usually difficult to process, can be processed using these excellent machines.

Brand names and manufacturers of sliding headstock automatic lathes
