This is a case study of ceramic pin machining by Sanwa Creation. We introduce our achievements in precision micro-machining with a minimum diameter of φ0.03, pin machining not only in round shapes but also in triangular, square, and oval shapes, as well as our diverse processing results for ceramics. Processed materials include alumina, zirconia, silicon nitride, silicon carbide, hot-pressed ceramics, steatite, and more. We can accommodate both cases: when you provide the materials for us to process and when we procure the materials ourselves for processing. Applications for the products include pin gauges, ejector pins, pilot pins, positioning pins, and more.

This is a grinding pin used in a pin mill type grinder for crushing various foods and pharmaceuticals. The pin materials available include steel, stainless steel, carbide, fine ceramics, and SKH51, among others. Since we manufacture to order, you can freely specify the dimensions of the pin, whether or not to include a chamfer, surface roughness, etc.

Before drilling the substrate, these are stack pins (positioning pins/small diameter pins) that are driven in when securing the entry board and backup board (bake board). The outer diameter ranges from Φ1 and the total length is approximately 8L. Chamfers can also be added to both sides of the pin. Precision: φ±0.005 (higher precision tolerances are also possible), outer diameter surface roughness Ra0.1 or less is achievable. Material: SKH51 (HRC60 or higher), SUS materials, carbide, etc. We can manufacture from small lots, so please feel free to consult with us.

We would like to introduce the "Triangular Prism Reamer Pin" handled by Sanwa Creation Co., Ltd.

In applications where high hardness, wear resistance, and chemical stability are required, zirconia ceramic pin gauges are an effective choice. Here, we will clearly explain the features of zirconia pin gauges, their differences from carbide pin gauges, and examples of applications. **Features of Zirconia Pin Gauges** Zirconia is a ceramic with the following characteristics: - High hardness and excellent wear resistance - Non-magnetic and electrically insulating - Excellent corrosion and chemical resistance - High dimensional stability due to thermal expansion rate being close to that of metals These characteristics make them effective in the following situations: - Measurement of non-magnetic parts in contact with metals - Measurement in corrosive liquid or chemical environments - Precision measurement applications where even slight displacements matter - Manufacturing processes that require clean environments and electrical insulation **Differences from Carbide** **Advantages of Zirconia:** - Non-magnetic and does not conduct electricity - Strong against chemicals, with a long lifespan even in corrosive environments - Smooth surface with minimal foreign matter adhesion - Less prone to fine dimensional changes due to wear **Advantages of Carbide:** - Slightly superior impact resistance and breakage resistance - Relatively low cost - Extensive processing track record and availability If you are struggling with the selection of materials and specifications for pin gauges, please feel free to consult with Sanwa Creation.
