ECOROLL Processing Cylinders Segment Cage for Skive/Burnishing Tools RDO and RIO and Roller Burnishing Tools Type R

OMEGA System (RDO, RIO) and tool types SK, GZ: Internal machining of hydraulic cylinders and cylinder liners 

ECOROLL's OMEGA system combines skiving and roller burnishing for machining hydraulic cylinders and cylinder liners. While the OMEGA skiving head cuts the cylinder's inner surface to the exact size and form required, the roller head burnishes it. The simultaneous skiving and burnishing process has almost completely replaced honing as the alternative machining process, since it is much more economic and faster. Thanks to its modular design, customized tools can be configured based on pipe quality and machining length. 

Sometimes for various reasons, tubes have to be skived and burnished separately or both processes have to be carried out one after the other. Therefore, all SK skiving heads can be delivered also as separate tools. SK skiving heads are then used in conjunction with GZ roller burnishing tools. In the first pass the SK skiving head peels the cylinder, and in the second pass the GZ tool burnishes it smooth. For cylinders with blind holes or steps, special blind hole skiving heads are available.

For machining short hydraulic cylinders with a length to diameter ratio of L/Ø ≤ 15 ECOROLL's SKOC and GZC tools can be applied directly on the lathe in one setting. The cylinders are premachined by a skiving head. After an automatic tool change the work piece is then finish machined by a separate roller burnishing tool. This process usually requires two toolplaces with one boring bar.

• Diameter range: 205 to 805 mm.
• Dimensioning: For 3 diameter ranges (205 to 405 mm; 405 to 605 mm; 605 to 805 mm) a variable number of standardized cage segments is used.  Only one segment type is necessary for the whole diameter range. This circumferential distance between the segments may vary depending on tool diameter.
• Can also be applied for Type R tools.

• Replacement of worn rollers or cage segments without removing the tool from the machine and without other disassembling.
• Opening of a “window” for quick inspection of the cone surface.
• Easy assembling also in horizontal position.
• Only segments are replaced when the roller pockets are worn out.
• Segments are standard components (only one type for all tool diameters)
• Roller diameters enlarged to 20 mm. Increased service  life of the rollers.
• Significant shortage of machine downtime.
• Short delivery of spare segments.
• Compatible with existing tools.

• The cage consists of a number of segments which are screwed on that segment carrier.
• One single or all segments can be disassembled. It is neither necessary to remove the tool from the machine nor to disassemble other parts for this operation.
