Stream Finishing Units – sf -SERIES automation

The SF -series automation offers deburring, rounding and smoothing in a single processing stage, in a very short time and without detriment to the contours of the workpiece. Path-controlled motion enables specific areas of a workpiece to be processed more intensely. Because of the tremendous processing forces involved, the SF Automation provides fast and economical finishing and guarantee absolutely reliable processing results. The SF -series automation of machines can optionally be equipped with pulse finishing and because loading is carried out automatically, they are suitable, among other purposes, for production lines with a predefined cycle time. Depending on the requirement profile, the machines can be pre-equipped automatic loading or optionally equipped with integrated automatic loading. The modular design of the machine means that it can easily be adapted to the cycle time. This enables the SF Automation to be easily incorporated into a production line as an integral component of the line. Typical applications for the SF -series automation include deburring, rounding, smoothing and polishing of camshafts and components with complex geometries such as thread-cutting dies and fuel injectors.

Automatic workpiece loading

Automatic loading and changeover of workpieces by robot or loading system.

Perfect finishing results

The SF enables several stages of processing to be carried out very quickly in a single operation. For example, a workpiece can be successively deburred, edge-rounded, smoothed and polished in one operation. The position-controlled movement sequence enables individual parts of a workpiece to receive intensive selective finishing. Thus the amount of material removed can be regulated right down to the µm level.

Fastest finishing process

Tremendous processing force and high stream speeds result in extremely fast and economical finishing of the workpieces. The automatic loading makes the SF -series automation perfect for processing high quantities and for integrating into a production line.

Customized solutions

Number and design of workpiece holders can be customized to suit requirements. Depending on your needs, we carry out individual adjustments or develop a customized solution based on your requirements.
