The "Internal/External Diameter Lapping Device" can polish and finish the inner diameter of collars and the outer diameter of bosses with grooves using lapping tape. The attachment and detachment of the workpiece is performed by the operator, while the opening and closing of the door, workpiece chucking/unchucking, and processing are carried out automatically by a semi-automatic machine. The contact part (the area polished with tape) is developed uniquely by our company (patented), making the tape routing easy. 【Features】 ■ Easy tape routing due to our unique development (patented) ■ The device's width is minimized, making it suitable for processes with multiple machines ■ Vertical design requires less floor space ■ Proven results with tape lapping, eliminating the grinding process *For more details, please refer to the PDF document or feel free to contact us.

The "Shaft Journal Grinding Device" grinds the bearing part (outer diameter) of the shaft using a wrapping tape, removes burrs from other processed areas with a brush, and blows away coolant drips from the shaft grinding area using air blow. The supply and discharge of the workpiece are done using a gantry loader, which is optional. 【Features】 ■ Reduction in total cost ■ Compatibility with various workpiece types can be selected via a touch panel recipe ■ Provides satisfactory values by selecting the wrapping tape (Please consult us regarding the roughness of the pre-processing) ■ Supply of outer diameter tape wrap units is also possible (unit sales) *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 automobile manufacturer was looking to reduce friction in the inner diameter of bearing components in their transmission to improve fuel efficiency. In response, we proposed our "Inner Diameter Grinding Machine," which is capable of grinding the inner diameter of workpieces. As a result, performance evaluations showed that friction was reduced, leading to improved fuel efficiency, and they are considering the practical application of the device. 【Case Study】 ■Challenge - To reduce friction in the inner diameter of bearings and improve fuel efficiency. ■Proposal - Proposed the "Inner Diameter Grinding Machine," capable of grinding the inner diameter of workpieces. *For more details, please refer to the PDF document or feel free to contact us.

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.

We would like to introduce a case study proposed by Sanshin Corporation that addresses on-site issues. A certain medical device manufacturer had the concern that "the outer diameter of the pipes used in medical devices has dirt on it after the final process. Since it is for medical use, strong cleaning agents cannot be used, and the dirt cannot be removed." In response, we proposed our "outer diameter polishing device," which allows for the polishing of the workpiece's outer diameter. As a result, by changing the buff polishing process to film polishing, we were able to reduce the cleaning process. This improved the appearance of the finish and contributed to quality enhancement. 【Case Study】 ■ Issues - The outer diameter of the pipes used in medical devices has dirt on it after the final process. - Due to being for medical use, strong cleaning agents cannot be used, and the dirt cannot be removed. ■ Proposal - Introduced the "outer diameter polishing device" that allows for the polishing of the workpiece's outer diameter. - Conducted sample tests, and modifications to specifications according to customer requests are also possible. *For more details, please refer to the PDF document or feel free to contact us.

"Film polishing" is a polishing method that uses a film-like sheet surface called wrapping film, to which fine abrasive particles are adhered. This document serves as an introductory guide to the basic knowledge of film polishing, covering topics such as "What is film polishing?", the "Differences between film polishing and buff polishing," and the "Differences between film polishing and lap grinding." Please take a moment to read through it.

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.
