CNC turned parts | Horizontal turning technology | Vertical turning technology

Simple and highly complex CNC turned parts manufactured in large and small series

A total portfolio of 17 horizontal and vertical lathes enables us to cover a large bandwidth of machining dimensions and component geometries. From diameter 10 mm to 5,200 mm we offer our services for manufacturing of rotationally-symmetric geometries, flexibly and efficiently. Moreover, several of our lathes have integrated boring and milling units that allow 6-sided complete machining without changing machines. In conjunction with our milling centers and boring mills we are also able to manufacture rotationally-symmetric components with highly-complex prismatic elements. Our grinding technology reliably fulfills increased requirements imposed on dimensional and surface tolerances. Thanks to exclusive use of CNC technology, as well as our in-house programming with preliminary simulations, we manufacture precisely, economically, and with process reliability.

Knowledge base
What is CNC turning?
CNC turning is one of the most important manufacturing processes in machining. It produces rotationally symmetrical components in metal and other machinable materials, certain plastics for example. In this process, the workpiece to be processed (the turned part) rotates on its own axis while a fixed tool (the turning tool) is brought into its proximity in order to remove material. Its feed motion shaves off chips of material until the desired form (programmed in the machine controls) is reached. Complex spiral forms and screw threads are also possible. CNC stands for Computerised Numerical Control. Using this technology, workpieces can be automatically manufactured to high precision and in various different batch sizes (single components, small and large-scale series).

The range of CNC turning processes
  Facing
Facing creates a flat surface on the workpiece (front end, stepped ledges) by moving the tool directly perpendicular to the axis of rotation.
  Longitudinal turning
In longitudinal turning, the tool moves parallel to the axis of the workpiece. Here, the lathed object becomes a cylinder of a set diameter.
  Grooving
In the grooving process, the tool moves vertically or parallel to the workpiece axis, allowing, for example, grooves to be created. A similar process to grooving, “cut-off”, is used to separate a workpiece or a section of a workpiece from the rest.
  Shaping
Shaping allows any of those shapes to be created that could not be achieved by simple turning or facing. Examples of this are spherical knobs or non-axial shafts. While in free shaping, the feed is controlled by hand, CNC control allows for very precise and above all reproducible components to be created through the automated adjustment of feed and cutting motions.
  Taper turning
Taper turning is a form of longitudinal turning in which the diameter changes constantly. This allows the creation of conical forms, for example, Morse tapers, hollow shank tapers or truncated cones.
  Threading and tapping
Using profiled tools and the thread-cutting process, the surface of a workpiece can be given a screw thread. The tool in this process already presents the shape of the surface to be created. Tapping is a process allowing both inner and outer threads to be created. Here, the forward feed of the tool determines the pitch of the thread (mm per rotation).
  Rotary broaching/knurling
Rotary broaching is used when rotationally symmetrical or thread-like surfaces need to be applied to a cylindrical workpiece. In this, the rotary motion is also the feed motion. This allows teeth or knurled surfaces to be created.
  Roughing and finishing
As in other machining technologies, turning distinguishes between roughing and finishing. Coarse machining, “roughing”, takes off larger amounts of material because of the greater depth of cut and speed, accelerating the process. Only during the fine processing, “finishing”, are the final dimensions achieved and the demands of tight dimensional and surface tolerances fulfilled. Here, the cut depth and speed are highly reduced.

Surface treatment of CNC turned parts
So that we can deliver you your CNC turned parts ready for installation, we will be happy to take over surface treatment works, including inspection. Our high-performance and regionally developed cooperative network gives you access to the full scope of services – all in the one place.
  Mechanical processing
After CNC manufacture, turned parts can also be subjected to further mechanical processing. This includes treatments such as grinding, polishing, sand- or glass bead blasting. In addition, we can also offer various different marking technologies, such as engraving, dot peening, etching and laser marking.
  Heat treatment
In order to fulfil stringent demands regarding material hardness, toughness and concomitant long service life in CNC turned parts, we also carry out heat treatments. Potential processes here include annealing, hardening and tempering.
  Electroplating
To improve CNC turned parts’ resistance to mechanical strain and corrosion, they can optionally be electroplated. This is an electrolytic process in which the surface of the part in question is either coated or transformed. Together with our regional cooperation partners, we are able to offer you nickel-plating, galvanisation, bluing and phosphate conversion.
  Coating and painting
The surface of CNC turned parts can also be optically and functionally improved by coating and painting. We will be happy to advise you on the painting options we offer in-house, such as powder-coating.
  Conservation
As the finished CNC turned parts are directly destined for temporary storage or shipment, conservation and corrosion protection are very important. From the targeted use of protecting materials to specialist packaging, we guarantee the best possible safeguarding of your precision components. Do you want to commission a CNC-turned part?
