With a setup change time of less than 5 minutes, it is ideal for a variety of products in small lots. Its main applications include various straight shafts for automobiles and construction machinery, motor shafts (single shafts), rollers for printers (rubber, resin, metal), and inspection pin gauges. If you would like to request a sample test, please feel free to contact us! For more details, please inquire or refer to the catalog.

The "SFBS-UN" is a grinding unit specifically designed for ball screws and external diameter screw grooves. The vertical mechanism improves the uniformity of the finish on both sides of the screw grooves. It is capable of achieving surface precision of Ra 0.1 to 0.05, which was not possible with conventional methods. Additionally, by feeding the tape while grinding, it can consistently finish with a new abrasive surface. 【Features】 ■ Improved uniformity of the finish on both sides of the screw grooves due to the vertical mechanism ■ Achieves surface precision of Ra 0.1 to 0.05, which was not possible with conventional methods ■ Surface precision improves in a short time, allowing for a uniform surface finish ■ Consistently finishes with a new abrasive surface ■ Unlike manual grinding, it is not significantly affected by the operator's experience *For more details, please refer to the PDF document or feel free to contact us.

"MFIL" is a unit for precision grinding the inner diameters of various bushes and similar components. It can be attached to lathes and other machines for precision processing. By simply replacing the grinding film, you can achieve the desired surface accuracy according to your needs. Additionally, since it grinds while feeding the tape, it can consistently finish with a fresh abrasive surface. 【Features】 ■ Achieves surface accuracy according to the purpose ■ Capable of precision finishing on inner diameters, outer diameters, and tapered sections ■ Allows for precision finishing regardless of experience level ■ Consistently finishes with a fresh abrasive surface ■ Usable for both dry and wet processes while maintaining a clean and compact working environment *For more details, please refer to the PDF document or feel free to contact us.

The "SFM" is a unit for precision grinding of shafts and similar components. It can be attached to lathes and allows for precision machining. Additionally, depending on the workpiece, the film width can be selected, enabling high-efficiency and low-cost processing. It is primarily introduced in the final finishing process of various automotive parts shafts and is suitable for improving the roughness of sliding and sealing areas. The outer diameter grinding unit can also be applied to grinding end faces and inclined surfaces. We offer a lineup of grinding units that can be attached to customer lathes and table-top grinding machines equipped with work rotation mechanisms. Furthermore, it can be used for both dry and wet processing, and the processing environment is clean and compact. 【Features】 - Achieves approximately 30% space-saving compared to conventional machines - Can obtain surface roughness according to purpose - Allows for precision finishing regardless of experience level - Capable of uniform finishing with a constantly new abrasive surface - Processing environment is clean and compact *For more details, please refer to the PDF document or feel free to contact us.

Are you having trouble improving surface roughness accuracy? Would you like to try the benefits of film polishing? You can polish quickly and easily without the hassle of the fine touch required in grinding with grinding wheels! 【For example, in the following cases】 ■ You want to improve roughness accuracy without worrying about changes in diameter or height dimensions. ■ You have performed grinding with grinding wheels, but it is still insufficient. – Final polishing is needed! ■ You want to finish with film polishing, skipping the grinding wheel process from the turning marks. ■ You want to roughen a surface that is too smooth. ■ You want to remove foreign substances attached to the surface. ■ You have tried various methods but they haven't worked well. ■ Polishing new materials or thin items seems unlikely to succeed without film polishing. *For more details, please request materials or view the PDF data from the download.

Sanshin Co., Ltd. is a manufacturer that designs and manufactures tape polishing machines based on technology, experience, and years of proven results, tailored to your needs. "The Collection of Case Studies on Sanshin's Film Polishing Technology" is a compilation of case studies on the film polishing technology handled by Sanshin Co., Ltd. It covers the basics of film polishing, the characteristics of Sanshin films, and the Sanshin technology that meets a wide variety of needs. We also introduce case studies from medical device manufacturers, automotive parts manufacturers, and electronic device manufacturers. ■ There is dirt after the final process, and strong cleaning agents cannot be used, making it impossible to remove the dirt... ■ We want to improve the roughness of the ball screw groove to reduce noise and enhance rolling performance. ■ We want to remove burrs that appear when making small holes in flat plates. Sanshin can solve these problems! 【Featured Case Studies】 ■ Medical Device Manufacturer - Proposed an outer diameter polishing device. ■ Automotive Parts Manufacturer - Proposed an inner diameter polishing device. - Proposed a ball screw polishing device. ■ Electronic Device Manufacturer - Proposed a flat surface polishing device. *We are currently accepting sample tests! For more details, please refer to the PDF document or feel free to contact us.

It provides an easy-to-understand explanation using diagrams on how the polishing is done and how it compares to other polishing methods. [Contents] ■ How is the polishing done? ■ How does it differ from other polishing methods? ■ What is the roughness of the finish? *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study proposed by Sanshin Co., Ltd. that addresses on-site issues. A certain automotive parts manufacturer was looking to improve the roughness of their ball screw grooves to reduce noise and enhance rolling performance. In response, we proposed our "Ball Screw Grinding Machine," which is capable of film polishing the ball screw grooves. As a result, they were able to achieve noise reduction and improve the rolling performance of the balls. 【Case Study】 ■ Challenges - Improve the roughness of the ball screw grooves - Reduce noise - Enhance rolling performance ■ Proposal - Proposed the "Ball Screw Grinding Machine" *For more details, please refer to the PDF document or feel free to contact us.

As products become more advanced, there is a growing demand for more precise polishing methods. The polishing equipment handled by Sanshin uses polishing films coated with abrasive particles on polyester film, making it easy to improve surface roughness and flattening in the final finishing process of various workpieces. While manual polishing requires skilled techniques, introducing polishing equipment can also address issues related to labor shortages and the transfer of skills. This document explains the purpose and features of Sanshin equipment. [Contents] 1. About film polishing methods 2. Outer diameter polishing equipment 3. Inner diameter polishing equipment 4.
