Honing with High-Speed
The high-speed honing machine vision Ultimate is more economical honing processes. The concept also means that the machine can flexibly adapt to changing workloads.
Productive and flexible, the vision to make the Ultimate honing. Similar to other high-speed manufacturing technologies such as milling or turning, should shorten the processing machine significantly. Together with the Nürtinger Honspezialisten Bernhard Henzler took the sword from machine-Schömberg Schörzingen the development challenge. To recover the honing process as high-speed processing, it was Necessary to increase the rotation speed of the honing tool and the same proportion the lifting speed. This was a radical change of existing machine designs have been necessary, says CEO Rainer Degen.
The tool is clamped directly into the hydraulic expansion chucks by means of honing spindle that rotates at up to 12 000 min-1. The rotation is less than 3 microns. An inner coolant supply brings the lubricant through the spindle and the tool directly to the cutting edge.
An essential part of the puzzle is the increased lifting speed. The lifting movement is carried out conventionally, on the one hand, the honing spindle, and also by a high-speed linear drive, which is responsible for counter-movement of the workpiece with up to 40 strokes per second. It was necessary to the masses, the speed of oscillation and to brake, are kept to a minimum. The newly developed high-dynamic linear drive allows for absolutely accurate Umsteuergenauigkeit. He is, according to a novelty sword and was realized with the support of Siemens.
- Even the tool concept are the Swabians own way. They rely on sleeves tools that might offer some advantages:
- The cylindrical and concentric widening process guarantee security in the form of dimensional accuracy and tolerance of the machined hole.
- The disposable sleeve almost completely replaced the repair and tool management. This enables a very small stock of tools is necessary.
- The cylindrical sleeve, even with an interrupted cut a dimensionally accurate drilling.
- The tool body is inexpensive to manufacture.
- Various combinations of materials in the workpiece are possible.
- The sleeve can be provided with a twist, which entails the honing oil perfectly into the hole.
- The core tools can be used on all conventional honing.
The developers of the Ultimate Vision also laid great emphasis on the modular structure of the machine as well as the possibility to expand them sequentially as needed. Thus, the standard machine is available as a stand-alone solution available, and - according to the required production volume - at any time to add new modules. Linked to the machine units through a sophisticated handling system. Within each machine can be placed next to the actual honing process for post-processing stations or stations.
