The "Thin Plate Flat Grinding Device" performs flat grinding using a lapping film (grinding tape). The workpiece can be attached and detached by the operator, and it can automatically grind the specified area. It is effective for grinding various substrates and for removing fine burrs from punched parts. 【Features】 ■ Film width can be selected based on the workpiece (supports two types) ■ Achieves high efficiency and low-cost processing ■ Effective for grinding various substrates and for removing fine burrs from punched parts ■ If a sub-table is provided, external setup can be done during processing time *For more details, please refer to the PDF materials or feel free to contact us.

The "Stamping Back Surface Polishing Device" can polish the back surface of a stamper using a wrapping film. The clamping (fixing) and unclamping (removal) of the workpiece is performed by the operator, while roll polishing, pad polishing, brush cleaning, and air blowing are done automatically. Various surface roughness requirements from different companies can be accommodated by selecting the appropriate wrapping tape and adjusting the parameters of the device to enable processing under optimal conditions. 【Features】 ■ It is possible to randomize the circumference of roll polishing with pad polishing. ■ Once the conditions are set, even beginners can operate it easily. *For more details, please refer to the PDF materials or feel free to contact us.

Super Finisher flat surface grinding allows even beginners to subtly differentiate the use of laps on the back side of the stamper original plate, and the environment is clean. The stamper back surface grinding device polishes the back side of the stamper using a lapping film. The clamping and unclamping of the workpiece is done by the operator, while roll grinding, pad grinding, brush cleaning, and air blowing are performed automatically. The various surface roughness requirements from different companies can be processed under optimal conditions by selecting the appropriate lapping tape and changing the parameters of the device. *Features* 【Stamper Back Surface Grinding Device】 - Various surface roughness requirements from different companies can be processed under optimal conditions by selecting the appropriate lapping tape and changing the parameters of the device. - The circumference of the roll grinding can be randomized with pad grinding. - Once the conditions are set, even beginners can operate it easily. 【Thin Plate Flat Surface Grinding Device】 - The film width can be selected according to the workpiece (supports two types), achieving high efficiency and low-cost processing. - Effective for polishing various substrates and removing fine burrs from punched parts. - If a sub-table is provided, external setup can be done during processing time. *For more details, please download the materials or 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 Co., Ltd. that addresses on-site issues. A certain electronic device manufacturer was troubled by the burrs that appeared when small holes were drilled into flat plates and wanted to eliminate them. In response, we proposed our "Flat Grinding Machine," which is capable of removing fine burrs that form on flat surfaces. As a result, the removal of burrs led to an improvement in quality. 【Case Study】 ■ Issue - Wanted to eliminate burrs that appeared when small holes were drilled into flat plates. ■ Proposal - Proposed the "Flat Grinding Machine." *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. [Contents] ■ What is film polishing? ■ What is Sanshin's Super Finisher? ■ Differences between film polishing and buff polishing ■ Differences between film polishing and lap grinding ■ Next time (internal diameter polishing, ball screw polishing, spherical polishing) *For more details, please refer to the PDF document or feel free to contact us.

Our company has developed various film polishing machines based on the concepts of "high precision" and "environment," and we have provided them both domestically in Japan and globally. This time, we would like to introduce three of our proud polishing machines: 1. Flat Polishing Machine → For flat finishing, flattening, and removing protrusions on various flat surfaces. 2. Outer Diameter Film Polishing → For ultra-finishing the outer diameter of various shafts. 3. Flat Lapping Machine → For lapping the end faces of workpieces using film. *The above three models will be exhibited at JIMTOF in November. Please come and see our technology at the venue (exhibition information is in the basic information section). <Reasons why our polishing machines are chosen> ■ Manufacturer specialized in film polishing machines ■ Customization (special jigs) support and proposals available ■ Sample testing before installation possible with various demo machines ■ Proposals for optimal polishing conditions based on processing know-how

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. Flat polishing equipment 5. Automatic supply and discharge *For more details, please refer to the PDF document or feel free to contact us.
