Stream finishing machine SF 1 ILS

The solution of choice for processing small workpiece batches and frequently changing series.

Equipment:SF 1

  • The SF1 ILS with chain loader is the new standard in automated precision fi nishing. The machine requires no expertise in robotics and is designed for maximum user friendliness. Both the SF and the chain loader are operated via a control panel. It features a chain loader with 64 or 160 positions and can process different workpieces in a single batch. Workpieces and collets can be changed automatically as required. Processing times range from 30 to 300 seconds, depending on the process and workpiece geometry.

  • With a processing time of 60 seconds per workpiece, the machine processes around 40 workpieces per hour. The SF1 ILS features a lifting unit for the workpiece holder and is suitable for both stream and pulse fi nishing in wet or dry processing. All these features make the SF1 ILS an extraordinarily effective and fl exible machine. Ideal for processing small batch sizes and frequently changing series.


  • Integrated loading system via chain and gripper system

  • Integrated loading system with automated changing system for collets tallow loading of various shank diameters

  • Maximum workpiece diameter: 3 - 18 mm (more diameters are planned)

  • Maximum workpiece length: 150 mm (other lengths on request)

  • Depending on the finishing process and the tool geometry, processing times are between 30 and 300 seconds

Precision finishing

This fast mass fi nishing process ensures extremely short process times, even with complex shapes. Parts can be deburred, rounded, smoothed or polished in a single work step. This process also effortlessly achieves roughness depths of far below 0.1 μm.

Rounding cutting edges

Rounding a tool’s cutting edge by even a small amount like 15 μm can stabilise the edge and ensure a perfect, burr-free geometry. This protects the edge against breakages and signifi - cantly improves both the service life and process reliability of the tool.


With smoothing, the roughness of the surface is reduced, i.e. the unevenness in the peaks on the surface are removed. The benefits this brings include reduced friction, higher contact ratios and less wear. A further benefit is the removal of droplets after PVD coating.


In addition to improving the appearance of the workpiece surface, polishing also improves the physical properties of the surface. A polished chip fl ute on carbide cutters and drill bits can increase the maximum cutting speed, for example, as well as boosting coating adhesion. A polished forming die will have a longer service life and lower friction coeffi cients.

ZOTEC stream fi nishing machines offer versatile, fl exible and effi cient surface fi nishing for small or large series production. If required, they can be fi tted with the right automation systems for every application.

By choosing an OTEC SF, not only are you choosing uncompromising German quality, but a secure future too.With a comprehensive range of standard equipment, optional extras and countless automation choices, our machines help you scale your production.

You can increase operating comfort and process reliability further with optional modules. Immersion depth control, for example, controls the immersion depth of the workpiece depending on the process. It can be programmed either manually or fully automatically. Wet processing machines feature a dosing unit that allows users to adjust the compound concentration via the touch panel.

Variant 1: Decentralised lifting unit

Here, all holders and workpieces are immers ed simultaneously. This version is mostly used with manual loading and unloading.

Variant 2: Centralised lifting unit

All lifting units are immersed individually. One workpiece is changed while the others are processed. This variant results in shorter downtimes and is mostly used with automatic loading and unloading.
