SFP-560A series (New)

The SFP-560A series fiber polisher is Seikoh Giken’s newest premium production polisher and the first in the marketplace to incorporate our patent pending Dynamic Pressure Control (DPC) pressurization system.

The unique DPC pressure technology offers a mass production platform incorporating highly stable, widely variable precision pressure control to the polishing Turntable. The pressure is applied from the bottom to the top. Moreover, SG’s advanced micro machining design guarantees polishing with perfect parallelism between the polisher's turntable and the rigidly clamped polishing holder by the 4 corners.

Combining proprietary bottom-up pressurization, precision speed & pressure control and rigid fixture parallelism, the SFP-560A series – while in DPC mode - realize epoxy removal of multi-fiber ferrule done by the SFP-560A series polisher and perform multi-fiber polishing similar in simplicity to standard single fiber connector polishing.

Incorporating the 4 Corner Clamp Post locking system from the Legacy SFP-550 series, the SFP-560A series polisher provides a wide range of benefits to the user ; 1) Backwards compatible with the full range of SFP-550 series IPC polishing holders*, 2) Open overhead work space for creative cable handling solutions for multi-fiber, large O.D cables.

Additional features include
1) Programmable polishing process up to 60* processes
2) Four (4) multi-timers for manual polishing operation
3) High Contrast, waterproof LCD Display with multi-language programming operation (ENG-CHN-SPN-JPN)
4) Selectable, password protected programming and operations modes for both administrators and users
5) Polishing program loading optional barcode scanner (inclusive for A3C)
6) Consumables info entry by barcode scanner (A3C only)
7) Operation and Maintenance Data metrics transfer via USB interface

*48 processes for A3C

The following models are available for the SFP-560A series and both models are inclusive of all the above mentioned features.

SFP-560A2 having manual clamping levers
SFP-560A2C having auto-clamping for less operator dependency
SFP-560A3C In addition to auto-clamping, it can manage consumable information, change speed and pressure at each polishing step, and connect to a network.

* IPC fixture / holders are polished in IPC mode.

SFP-550S3 has been discontinued.


SFP-550S3 has been discontinued.
Please consider SFP-560A3C as its successor machine.
Repair service and sales of maintenance parts will continue.

The replacement machine, SFP-560A3C, is a more advanced version of the SFP-550S3, which has not only consumable info management but also offers more advanced controls in time, speed and pressure with active pressure capability that you can expand range of polishing applications to include large O.D. cables polishing, MT and Fiber array.
Please contact our distributors and sales offices for more details.


The SFP-550E3 Polisher Series is Seikoh Giken's mid-range polisher offering a competitive priced, high volume programmable mass production model under our recently introduced concept "Ez-Maintenance and High Duty Cycle" series. Compared to the previous SFP-550 series, there is drastic improvement in ease of maintenance and machine robustness that has achieved reduction in maintenance cost (90% less per our internal test).

Unlike the previous model SFP-550E which had 4 individual timers, this new model SFP-550E3 features Multi Timer on LCD Touch Panel (4 timers). In addition, it features simplified polishing process programming (8 steps each x 12 processes). Polishing speed is variable from 70rpm to 200rpm for revolution and rotation speed is automatically adjusted as per revolution speed.

A notable feature of this polisher series provides the option to add a Center Pressure Module, which converts this machine to be used as an advanced multi fiber polisher.

(Note: the Center Pressure Module can be mounted to all SFP-550 series).

Polishing holders, films and pads are compatible among all 550 (120A) series

The SFP-550C Polisher Series is Seikoh Giken's entry level mass production model. The 550C series model was also developed under the recently introduced concept of "Ez-Maintenance and High Duty Cycle" series. And, compared to the previous SFP-550 series, there is dramatic improvement in the ease of maintenance and machine robustness that has achieved reduction in maintenance cost (90% less per our internal test).

The addition of the high speed turntable technology allows the SFP-550C model to increase productivity by more than 20% (according to our internal test) over previous entry level polishers.

All Seikoh Giken polishing holders come equipped with the proprietary IPC (Individual Pressure Control) system that provides even pressure to each ferrule regardless of it's protrusion length while achieving stable and high-quality output.

Efficient large scale mass production lines focused on cost/production savings can be established by installing this combination of polishing machine and IPC holder for each polishing step.
