CNC-MACHINING

Basically, turned parts are distinguished by the different separating processes:

• Turning
• Drilling
• Milling
• broaching
• sawing
• Reaming
• Shaping
• Honing
• Lapping
• Grinding 

CNC machines are equipped with a PLC (programmable logic controller). It serves as an interface between the respective plant and the CNC control. In addition, all safety-relevant automatisms, such as the prevention of collisions, are carried out in the PLC. 

Only the latest Siemens and Fanuq controls are used at TIGGES.

Our approach: all expertise at the beginning of the process. Through our expertise in design and machine programming, feasibility is analyzed in advance. 

In addition, risks are assessed and equally prevented as part of an FMEA (Failure mode and effects analysis). 

Our experienced programmers then expertly set up the appropriate CNC machine. As soon as the programming is completed and the component is ready for drawing, sample parts are tested and released in our in-house quality assurance department according to a previously defined test strategy. Because the following applies: No production without QA release.

The service lives of tools and inserts are determined and taken into account by us in order to remain within the dimensions throughout the entire process.

During production, SPC checks are carried out at least every 180 minutes. In reality, however, measurements are taken at much shorter intervals, since a new SPC check is also carried out after each change of material, insert or tool.

1. prepare CNC program

In order for our production to act quickly and flexibly, our CNC programs are written in advance by experienced programmers. 

2. set up CNC machine

For our complex products we use different tools and tool plates. For special cases we use customized special plates. These are carefully installed and the bar stock is loaded into the bar feeder.

3. fine adjustment

After the machine has been set up, the CNC program is fine-tuned so that the components are produced in accordance with the drawings and, above all, in a manner that is stable in terms of production cells.

3. release

When the process stability is guaranteed and the components correspond to the drawing, the internal quality assurance department checks all dimensions again with appropriate measuring equipment and issues a production release.

3. process check

After the machine has been set up, the CNC program is fine-tuned so that the components are produced in accordance with the drawing and, above all, in a stable manner.

We use a wide variety of machine types for the most diverse requirements in terms of dimensions, tool design, and number of pieces. At TIGGES, we rely on modern machines from the manufacturers DMG Mori and Index.

• Multi-spindle lathe
• Long and short lathes
• CNC turning centers
• Milling machine
• Grinding machine
  Multi-spindle lathe

A multi-spindle automatic lathe is able to use several spindles at the same time. This means that they have a much shorter throughput time and are therefore used for particularly large production volumes. The effort in machine programming as well as the tool costs are usually higher.

Long lathe and short lathe

In the classic sliding headstock lathe, the material is pushed through a guide bush. This means that the longitudinal feed is performed by the material itself. This makes it possible to produce longer shafts without a counter spindle or tailstock, making sliding headstock lathes ideal for efficient series production of longer workpieces. In a short lathe, on the other hand, the material sits firmly in the spindle, clamped by a chuck or collet. which is why it is mostly used for short components.

CNC turning machining centers

Turning machining centers are machine tools that are suitable for complete machining, i.e. they combine the various functions of a lathe, milling machine and drilling machine.

In the future, machining will be fully automated and subject to maximum speeds. 

For this very reason, it is important that, in addition to the basic technical requirements, production is supported by our expertise. 

Already today, automated machining processes are possible at our company. This enables us to produce flexibly, quickly and to a high standard. Our knowledge enables us to optimize existing manufacturing processes and fully exploit the advantages of machining.
